How to set the ignition on Daewoo Matiz
Between the legs of the coil mounting clamp, an additional Daewoo Matiz ignition 8 is mounted in a ceramic insulator, connected in series with the primary winding of the coil and shunted when starting the engine to provide a higher voltage in this mode. Technical characteristics The maximum rotation speed of the distributor shaft at which the coil ensures uninterrupted sparking is no less than Remove the Daewoo Matiz ignition from the ignition distributor and, turning the engine crankshaft, set the breaker contacts to the closed state.
Turn on the ignition and periodically open the breaker contacts with a non-conductive object using a wooden or plastic stick.
Checking Daewoo Matiz ignition ignition on a stand On the stand, they check the maximum speed of rotation of the distributor shaft, at which the ignition coil ensures uninterrupted sparking, see. The stand for testing ignition system devices must be equipped with three-electrode needle gaps with a spark gap of 7 mm.
Spark plugs Design features Fig. Spark plug A20D1: The spark plug consists of a ceramic insulator 5 fig.
The insulator with all its constituent elements is secured in the housing by rolling. To ensure a tight connection between the spark plug and the cylinder head, a metal sealing gasket with a 3-shaped section is installed on the spark plug body.
Inspection and check of Daewoo Matiz ignition and removal of the spark plug from the engine, make sure that there is no mechanical damage to the thermal cone of the insulator and the electrodes of the spark plug.
Soot and carbon deposits on the heat cone of the Daewoo Matiz ignition insulator using a sandblaster, wash the spark plug with a brush in clean gasoline and blow with compressed air. Do not clean the spark plug insulator with sharp objects or a wire brush.

The resulting scratches provoke accelerated carbon formation. Due to uneven heating, the insulator warps and the spark plug loses its seal.
Adjust the gap by bending the side electrode 1. Check the serviceability of the spark plug using a special device under pressure. The preparatory work is the same as for adjusting the idle speed for the corresponding engine.
The ignition is adjusted when the engine is idling. Different engines require different jobs. Injection engines Position of individual Daewoo Matiz ignition of the fuel injection system and ignition system in the engine compartment of a car with an SR20DE engine Before checking and adjusting, certain conditions must be met in order to obtain accurate results.
The idle speed must correspond to the required value. After warming up the engine and connecting the tachometer and strobe light, do the following: With the engine turned off, locate the throttle position sensor (see Start the engine). Take tachometer readings. Take readings of the ignition timing in the strobe beam on the crankshaft belt pulley.
To do this, loosen the distributor mounting bolts, see Tighten the bolts again and check the ignition timing. In conclusion, again the Daewoo Matiz ignition plug. On vehicles without a catalyst, the ignition timing is adjusted in the same way. The crankshaft belt pulley has a notch on the edge to indicate ignition timing adjustment from the outside. The illustration shows ignition timing marks.
If, at the same time, the high Daewoo Matiz ignites gasoline, and even the engine troits, then you should pay attention to the performance of the high-voltage wires.
We are talking about the wires that connect the spark plugs. In this case, the engine can also ignite the Daewoo Matiz. Unfortunately, this indicates a malfunction of the control unit. To finally verify this, I made additional measurements of the signals, but directly at the ECU connector. The signals turned out identical to those on the ignition coil.
Conclusion - the electronic engine control unit must be replaced.
Unfortunately, repairing this ECU is almost impossible: There are, of course, methods, but I’ll probably tell you about this in another article, if I have a chance to do it.
Good luck and less breakdowns! Nikolay Bokov, Alexey Daewoo Matiz ignition. Parallel connections should be made using an adapter. Do not pull on the high voltage wire when removing it from the spark plug, but rather pull on the tip or use a tool designed for this purpose.
Spark plugs Fig. Example of spark plug marking: R - resistive type; 4 — thread size 14 mm; 6 — thermal regime; T—conical insulator skirt; S Daewoo Matiz ignition extended electrode tip All engines, with the exception of engines with an aluminum cylinder head, have resistive type spark plugs with a conical insulator skirt.
When installing such spark plugs, the use of gaskets is not required.
The spark plug marking system is shown in Fig. The first and last letters indicate the specific type of candle.
Problems of the Daewoo Matiz ignition system and ways to solve them. Matiz ignition
The numbers indicate the thread size of the Daewoo Matiz ignition thermal mode. The first Daewoo Matiz ignition designates the thread size: The second number indicates the thermal mode: Under normal operating conditions, the engine can operate in idle, slow speed and high speed modes.
Occasional or periodic driving at high speed is necessary to improve spark plug performance. This releases more heat, which burns away carbon and other deposits that form when the engine is idling frequently or when driving in stop-and-go traffic.
The spark plugs are protected by an insulating tip made of a special heat-resistant material that covers the spark plug terminal and part of the insulator. If the ignition is set incorrectly, the symptoms will be the same as with a faulty distributor. If everything was done correctly, the car will function properly. However, to be absolutely sure, visit a service station and let specialists accurately check the ignition timing, which may have gone astray when installing the distributor.
Next, with the Daewoo Matiz ignition, follow the same steps to ensure the absence of detonation with sudden pressure on the gas.
If everything is adjusted correctly, detonation will last about 2 seconds, if it is absent or when it lasts longer, adjustment is required. Daewoo Matiz ignition set the distributor by turning one tooth in the direction of adjustment. Adjustment using a strobe It is recommended to warm up the engine to operating temperature, then be sure to turn it off. We connect terminals A and C of the diagnostic connector using additional wire 1, or connect the Daewoo Matiz ignition diagnostic tool to the connector.
Matiz revs the engine at idle speed. Daewoo Matiz
As soon as the first cold weather sets in, driving a car without a heater becomes uncomfortable. In addition to comfort, there are also safety issues, because if there is no heat in the cabin, the windows will be icy and the driver will not have a normal view, which can cause an accident.
What happens in cases when:
- the stove does not work at all;
- Cold or slightly warm air is blowing, despite the fact that the control on the panel is set to maximum.
No fluid in the system
The most common reason why the heater in a Daewoo Matiz does not work is insufficient level or lack of coolant. Initially, the cooling circuit is sealed, but it may well happen that one of the hoses or the expansion tank, which is made of plastic, cracks and antifreeze begins to leak.
It is recommended to check the coolant level before each trip using special notches with the Min and Max inscriptions on the tank. The lack of coolant can threaten not only that the stove will not work, but also such a major breakdown as an engine wedge, which will put the Matiz out of action for a long time.
Thermostat failure
If the coolant level is normal, but the stove still does not heat, then check the thermostat next. When starting the engine, the coolant first circulates through a small circuit so that the engine warms up quickly, which is especially important in cold weather.
Further, when the temperature reaches the desired level, the valve opens and the liquid begins to circulate along a common circuit, from which the heat is taken into the cabin. This valve is called a thermostat. If it doesn't work and remains closed, then in Matiz.
Since the thermostat is a mechanical device, it can simply get stuck in one of the positions. The problem is solved by replacing the thermostat. It is quite inexpensive for a Daewoo Matiz.
Airlock
When replacing coolant or adding to the expansion tank, this may occur. Its characteristic feature is that the stove seems to be working properly, but the air coming out of it is barely warm. There are several options for getting rid of an airlock. You can lift the front of the car on jacks or drive it onto a hill, unscrew the cap on the expansion tank and give it a good rev. The second way is to remove the clamp on the pipe, but remember to take precautions, as you can get severe burns. The best thing to do is simply go to the nearest service station.
Radiator or filters clogged
A large amount of dust, sand and dirt, insects, fluff, etc. accumulate on the radiator and cabin filter. This can cause the Matiz stove to heat poorly.
It's quite easy to check:
- start the car;
- Warm up the engine to operating temperature according to the dashboard. If everything works properly, then warm air should start flowing from the stove as soon as the coolant temperature reaches 50 °C;
- if the air is cold, carefully try the pipe entering the radiator with your hand; if it is hot, then.
How to clean the radiator and stove in Matiz without removing them
It is best to use proprietary cleaning compounds, which take into account the material from which the radiator is made. In addition, it is necessary to thoroughly blow it with compressed air from the compressor.
You can also use one of the following traditional methods:
- Hydrochloric, sulfuric or phosphoric acid is mixed with water in a ratio of 1:10. After this, the solution is poured into the radiator for 2–3 hours. Then start the car and let the engine run for 15 minutes, turn it off and let it cool. The mixture is drained and the system is washed with clean water at least three times. Important!
Strictly observe the time, because if you “overexpose” the acid, it will begin to corrode hoses, gaskets and everything made of rubber. The safest option is to use ordinary whey instead of acid. - Dissolve citric acid (500 grams) in 7 liters of distilled water, pour it into the system and drive the car for a week. Then the water is changed back to antifreeze or antifreeze. Important!
You can use this advice only at above-zero temperatures so that the water does not freeze. You cannot use ordinary water, only distilled water, otherwise the opposite effect may occur when scale forms. - Coca Cola. A method that must be treated with extreme caution. Boil two liters of the drink and pour it into the heater through a funnel, having first removed the supply hoses from it. Wait an hour and rinse the radiator with clean water at least three times.
How to eliminate common causes of failure of the Daewoo Matiz ignition system?
Thus, the control device recognizes the TDC of cylinders 1 and 4 and, accordingly, cylinders 2 and 3.
Pressure sensor Pressure sensor 1 is mounted in a holder on the front wall. If the ignition timing is adjusted incorrectly, the cause of the malfunction may be a damaged or incorrectly installed low-pressure hose 3.
In this case, problems will also arise with idle speed due to sharp fluctuations in engine speed. In addition, it is necessary to check the plug connection 2. In this case, never pull on the cable, only on the plug itself after removing the safety clip.
Mirrors and glass
If there are outside rear view mirrors, there should be no scratches or cracks. All glass is checked for the same purpose. Each of them has a factory stamp with the year of manufacture. If the stamps are different, and the year of manufacture does not coincide with the manufacture of the car, then the glass has been changed. The windshield can be replaced frequently due to impacts from bouncing stones and does not serve as a criterion for an accident. The rear window and side windows are more revealing.
Daewoo Matiz won't start
It is located in the Daewoo Matiz ignition fault module holder on the front wall and is connected by a hose to the intake pipe. Via the hose, the pressure in the suction pipe influences the pressure-sensing crystal chip in the pressure sensor. Depending on the pressure in the suction pipe, the resistance value of the crystal chip changes. By changing the resistance, the control device receives information about the pressure created in the intake pipe.
The pressure in the suction pipe and the current rotation speed are compared with each other and the control device determines the optimal engine load.
Knock Sensor Knocking combustion with too early ignition timing is harmful to the engine. The consequences may be overheating, damage to bearings and pistons.
On the other hand, early ignition provides the greatest engine power and is at the limit of detonation.
This detonation limit depends on too many factors to be accurately determined. Therefore, all Renault 19 gasoline engines are equipped with a knock sensor, which detects its presence.
The knock sensor is installed between cylinders 2 and 3 in the cylinder head. This material is well known from lighters, in which it produces sparks to ignite gas.
Mechanical forces, traction and pressure, which act on piezoceramics, are converted by it into electrical voltage. Although I somehow changed the fuel filter, I removed the pump fuse on a working engine - and it stalled at the same moment.
After all sorts of manipulations, replacing spark plugs, wiping headlights and all that, the engine still starts for the same 10 seconds. And at this time you can not touch the gas pedal - the engine runs smoothly without failures. Or you can push the gas full throttle, it picks up speed until the cutoff, back and forth, 10 seconds pass and it stalls.
I removed the fuel hose from the fuel rail, drained half a liter of gasoline, clean without impurities, without dirt, without ignition faults in the Daewoo Matiz. I found an alarm unit under the dashboard, a VALET button, there was nothing in the instructions for a Daewoo Matiz ignition fault, how to completely turn off the alarm.

Next, we will consider both the most common and less common causes of such a malfunction. If at the same time there is a high gasoline consumption, and even the engine is running rough, then you should pay attention to the faulty ignition of the Daewoo Matiz high-voltage wires. We are talking about the wires that connect the spark plugs. In this case, the engine may also trip. This is the only sensor whose malfunction will prevent you from even getting to the garage. His refusal is an exceptional phenomenon.
Based on the synchronization pulse from the crankshaft position sensor, the controller determines the position and speed of the crankshaft and calculates the moment of activation of the injectors and the ignition module. Fuel pump - you won't go anywhere. If the fuel pump begins to work worse, the reasons are mainly due to dirt and water in the gasoline, then dips, loss of power, and popping noises appear in the intake system.
If it completely dies, then the Daewoo Matiz ignition faulty car will continue to drive: If all other sensors and mechanisms are faulty, the engine will work: Although the engine operates in an abnormal mode of pairwise parallel fuel supply, when each injector fires twice as often once for each revolution of the crankshaft - do not try to determine this by ear.
The exhaust of the Daewoo Matiz is as clean as before, but the increase in toxicity can only be caught by measuring the driving cycle.
Problems of the Daewoo Matiz ignition system and ways to solve them
You can tell that the engine is unhealthy by the increased fuel consumption. Another sign of a malfunction is a malfunction of the self-diagnosis system. The first thing I did was remove the timing belt cover and make sure it was properly tensioned. This is already good!
Daewoo Matiz ignition malfunctions step by step I connect to the distributor with a motor tester. But before we get into the web of wires, let's look at the diagram to understand where we will connect the motor tester and what we will look at. Here is a diagram of the ignition system of this engine, the picture is clickable: As can be seen from the diagram, only four wires come to the distributor connector.
And two more wires going to the ECU: I jumped ahead a little and didn’t say that the ignition coil on this engine is controlled by the ECU. This is a typical scheme for cheap cars: Well, now it’s time to check everything thoroughly.
Replacing the timing belt for Daewoo Matiz with 0.8 engine
Many Matiz car owners turn to car repair shops for engine repairs, including trusting the technicians to replace the timing belt. But the work of replacing parts of the gas distribution mechanism is not very difficult, and if you have even minor plumbing skills, you can do it yourself. The most important thing in this matter is to correctly set the marks on the camshaft and crankshaft - if they are set incorrectly, the valves will be bent, and the repair will then be much more serious.
We replace the timing belt on the F8CV engine as follows:
- we place the car on a level surface; it is not necessary to perform work on a pit or a lift;
- turn off the engine, remove the negative terminal from the battery;
- jack up the car, take off the front right wheel, and put chocks under the rear wheels. It is better to install a stop next to the jack; such insurance will not hurt;
- dismantle the timing belt casing;
- remove the generator belt;
- we stop the crankshaft from turning (you can stick 5th gear on the box), tighten the crankshaft pulley bolt;
- dismantle the shaft pulley,
- remove the tube with the oil dipstick;
- we set the marks - it should be installed on the camshaft, as in the figure below. It is important not to confuse the marks - the second mark on the gear is only needed for adjusting the valves;
- unscrew the bolts of the lower casing, dismantle the timing belt protection;
- the mark on the crankshaft must also match;
- loosen the tension roller bolt and remove the belt;
- completely unscrew the roller bolt, dismantle the spring and the roller itself;
- to install a new roller, first fix the spring on it, then put the other end of the spring behind the font;
- insert the tension roller into the fixing hole and tighten the bolt;
- tighten the bolt and move the roller as far as possible to the side so that you can easily install the belt;
- Having installed the belt, we tighten it;
- We check the marks match and perform assembly.
How to eliminate common causes of failure of the daewoo matiz ignition system?
Common reasons why a car engine does not start
The reasons can be both general and specific. Let's look at the most common problems.
First place, perhaps, can safely be given to problems with the battery. Very often the engine does not start as a result of the battery being discharged. It is not necessary that the charge be completely absent. In many cars, the starter refuses to turn if the battery produces less than 10 volts. Taking into account this information, it becomes clear that you should not forget to recharge the battery on time. However, complete failure or problems with starting the engine are not always associated with a low battery charge level. Quite often, oxidized or poorly secured terminals are to blame. From time to time you need to clean them with sandpaper to remove the deposit of oxide film, which is a poor conductor of electricity. The same applies to the contacts on the battery itself. After cleaning, it is recommended to lubricate the terminals with machine oil or lithol so that they do not oxidize. Better yet, replace the copper terminals and install brass ones.
In second place in terms of frequency is a very simple and harmless reason - lack of fuel. There are two options: it may not be in the tank, or it may not enter the engine. The driver's actions in this case are extremely simple. First, check the tank (the sensor may fail or show incorrect values). Secondly, check the fuel line. Perhaps there was a leak somewhere and it filled with air. The complexity and cost of repairs depends on the nature of the damage. Sometimes it is enough to simply replace the hose under the hood.
Fuel may not enter the combustion chamber due to a clogged carburetor or injectors on injection engines. In addition, it happens that the fuel pump fails. The reasons for this can be different, but the most common one is overheating of the fuel pump. Of course, we are talking about those cars in which the pump is installed under the hood (usually carburetor cars). It overheats especially often in the summer heat. Another option, although very rare, is that gasoline has lost its properties (evaporated, diluted with condensate, etc.). This happens if the car has been sitting for more than a year. In this case, it is enough to add fresh fuel or drain the remaining fuel, and then refuel with suitable fuel.
Problems in the ignition system
No spark at the spark plugs or wet spark plugs. This is also a very common reason why the engine will not start. You can check the spark plugs yourself. To do this, you need to have a spark plug wrench in the trunk. Checking for a spark is also not difficult. To do this, you need to unscrew the spark plug, put a contact wire on it and try to turn the ignition key at the moment when the spark plug itself is near the metal. A good spark should be fat and bright. If the spark is weak or absent at all, you should take a closer look at the spark plug contacts. Perhaps they are covered with soot. In this case, they must be cleaned with sandpaper or a wire brush. If this does not help, then you should try replacing the spark plug.
Adjustment of valves
The 0.8 liter Daewoo Matiz engine does not have hydraulic compensators, so the valves are adjusted manually. Typically, such an operation should be carried out once every 50 thousand kilometers; you can also adjust the valves yourself. The sequence of operations here is as follows:
- first of all, unscrew the valve cover bolts, for this you will need an M5 hexagon;
- There are 6 bolts in total;
- remove the front timing belt cover;
- set the TDC of the first cylinder;
- adjust using the feeler gauge on the 1st cylinder of the valve: on the intake – 0.15 mm, on the exhaust – 0.3 mm. We also adjust the intake valve on the second cylinder and the exhaust valve on the third. The locknut is loosened with a 12mm wrench, and the screw is adjusted with a flat screwdriver;
- turn the crankshaft further, align another mark on the camshaft with the “triangle” on the inner timing case - you need to set exactly this mark (there is an ebb under the numbers);
- we adjust the exhaust valve on the second cylinder and the exhaust valve on the third.
Close the valve cover, start the engine, listen to how the engine works. During adjustment, you need to pay attention to the condition of the camshaft cams, and if there is wear on them, it will not be possible to adjust the valves (they will knock) - in this case, you need to prepare to replace the camshaft.
So the day has come that I would not wish for any of the readers of our magazine... Having worked safely and faithfully all winter, Matiz did not show any signs of ill health and behaved quite normally. Pounding family worries, the birth of a child and related troubles did not allow us to pay enough attention to the car, and my wife and I simply forgot that after winter we needed to change the oil! As you already understand, today we will talk about such an unpleasant thing as a major overhaul of the Matiz engine .
Reasons for engine overhaul.
Under normal conditions, a major overhaul of the Matiz engine is required only due to the natural wear and tear of engine parts. And the Matiz engine resource is 250,000 km. – however, it may differ up or down depending on driving style, quality of oil used, climate and operating conditions of the vehicle.
But much more often, engines fail due to low-quality motor oil (fake, used and lost its quality - as was the case in my case), or due to insufficient oil level, which is due to leaks, or the fact that the engine “eats” oil , and its level decreases. Yes, besides everything, the oil pressure sensor on our Matiz did not work, and we had no idea about it, which is why it was necessary for a major overhaul - a penny item, but capable of causing so much trouble.
other reasons why a Matiz capital , and in one hundred percent of cases, major engine repairs are required solely due to the owner’s carelessness.
What happens to the engine if the oil level is insufficient or its quality is poor? The oil pump stops supplying oil to rubbing parts that operate under high loads - to the pistons, cylinders and crankshaft. The wear of parts increases sharply, the friction force increases, and “scores” appear on the rubbing surfaces - irregularities and cracks in the metal. As a result, the parts simply jam and the engine stops, often with destruction or deformation of the pistons, cylinder head, connecting rods, crankshaft liners, etc.
Making a diagnosis...
In any case, it is possible to determine what has failed in the engine only after removing it from the car, cleaning and disassembling it - which I highly recommend doing at a good car service center.
Here's what can fail and what options there may be for overhauling the Matiz engine:
– scoring on the walls of one or more cylinders. Not the most severe case - you will need to bore the cylinder block and install repair pistons of larger diameter (all three or four). If the connecting rods are destroyed, the situation is worse and repairs will cost much more.
– “sticking” and turning of the crankshaft liners. This is also a common occurrence, in my case it happened simultaneously with the piston jamming. It is treated by turning and grinding the crankshaft journals and installing repair liners. Complications can be that the crankshaft is deformed or destroyed - then it needs to be replaced, and it is quite an expensive thing.
- destruction of the cylinder head, torn connecting rods, burst bearings - and so on. A very difficult case - prepare for high costs for spare parts and consider the option of replacing the complete engine.
Signs of an engine overhaul
The main signs that a major overhaul of the Matiz engine awaits you soon are:
– dry oil level dipstick and warning lamp for emergency oil pressure;
– a sharp, growing knock in the engine (which will inevitably be replaced by complete silence after thirty to forty seconds);
– decrease in speed and power, “failures” in engine operation;
– vibration and unstable operation of the engine, increased temperature;
– black smoke from the muffler;
As with any disease, prevention is much cheaper than treatment, so I sincerely advise you to learn from my mistakes and carefully read the practical tips at the end of the article.
The cost of a major overhaul of a Matiz engine
The cost of a major overhaul of a Matiz engine consists of the cost of spare parts, engine overhaul and work on boring and grinding the cylinder block or crankshaft. The good news is that spare parts for Matiz are very affordable, and in terms of the cost of engine overhaul, it is one of the cheapest foreign cars. Here is the approximate cost of original spare parts for a major overhaul of the Matiz engine:
Work on mistakes. Daewoo Matiz: misfire, error P0300
An illuminated Check Engine light will alert us to the presence of errors in the system. In Daewoo Matiz, as in all modern fuel-injected cars, engine operation is controlled electronically. Testing the electronic control unit will help you understand what is causing the error. If a scanner or other diagnostic equipment shows the presence of error P0300, most likely we are dealing with a malfunction in the ignition system. The error code is typical for engines of Matiz, Lacetti cars, as well as related Opel, Hyundai and Kia engines.
Video “Daewoo Matiz car diagnostic process”
To see how the diagnostic procedure for a Matiz vehicle is carried out, watch the video.
How often will the owner of a minicar have to use the services of service station specialists - https://oiler.ua/sto/. The first Daewoo Matiz (“Daewoo Matiz”) came out in 1998. The exterior and interior of the car were designed by specialists from ItalDesign Giugiaro. In 2002, the car was restyled, redoing the front optics, hood, and rear lights. Since 2003, they began to install a 4-cylinder engine with a volume of 1 liter and a power of 64 hp. At the same time, the manufacturer offered an automatic transmission (variators were available for some countries). In 2004, Daewoo became part of General Motors, and cars were produced under the Chevrolet brand. With all the advantages, the car also has serious disadvantages.
When error P0300 occurs
The P0300 code appears when the problem is related to the ignition. The error code can be determined in the range P0300-P0312. The code values directly depend on the number of cylinders and the malfunction in each of them. For example, error code 0301 indicates a misfire in the first cylinder, and so on. When checking with a scanner, it will display a warning message about random multiple misfires on the cylinders. If the error is indicated as 0300, the problem is general sparking.
Error code on display
Nevertheless, it is the 300th code that is recorded by the scanner only when there is a failure in sparking in several cylinders at once. The failure is not stored in memory instantly, but only 210 seconds after the next operation at idle; at medium speeds, the error rate should be no less than once every 75 seconds. In this case, an ignition error in several cylinders is indexed only when more than 3.25% of all flashes are missed. If a specific cylinder is to blame, then we will see another version of this code - 0301, 0302 or 0303, if we are dealing with a three-cylinder Daewoo Matiz engine.
Diagnosis and symptoms of an error
Actually, you don’t need to be a great diagnostician or even have a scanner to visually determine a failure in the ignition system. If the check light comes on, and the engine is feverish at idle, the speed does not develop as before, jerks are noticeable when accelerating and starting from a stop, you can talk about error P0300 or its derivatives without a scanner. In addition, the symptoms that cannot be ignored are the following:
- Reduced vehicle traction.
- Difficulty starting the engine.
- Increased fuel consumption.
- Uneven operation at idle speed when cold.
- A sharp drop in power.
Any problem listed above is a wake-up call. Even if the electronic system does not signal for help, the driver should diagnose the systems himself and figure out what is causing this behavior of the car.
Main automatic transmission malfunctions and their causes
Automatic transmission has long been widely used in America, and in recent years it has become increasingly popular in Russia and the CIS countries. This is not surprising - an automatic transmission is more convenient for the driver, especially for use in the city with its good roads and frequent traffic jams. However, an automatic transmission is a mechanism, and like any mechanism, malfunctions can occur.
All malfunctions of an automatic gearbox (automatic transmission) can be divided into two large categories:
• Malfunctions of the electronic part; • Malfunctions of the mechanical and hydraulic systems of the box.
Malfunctions of the electronic part of the automatic transmission may be as follows:
• Failure of the electronic control unit (controller); • Damage to transmission and engine control system sensors; • Short circuits, breaks and other damage to electrical wiring; • Failure of actuating elements.
It should be noted that if a malfunction occurs in the electronic part of the transmission, the computer launches emergency work programs. These programs ensure the functioning of the gearbox even if certain elements break down, and different programs are provided for different breakdowns. If the breakdown is serious (for example, the automatic transmission electronic control unit or actuators have stopped responding), then the box is switched to emergency mode. Typically, in this mode, third gear is automatically engaged, which ensures that the vehicle can be driven with the greatest safety. The car cannot be operated normally in emergency mode, but it is quite capable of getting to the repair site.
Malfunctions of the mechanical and hydraulic automatic transmission systems can be as follows:
• Wear of gears and shafts; • Wear or damage to friction elements (clutch discs, brake bands); • Various torque converter malfunctions; • Malfunction of the torque converter lock-up clutch; • Malfunction of the torque converter stator (reactor) overrunning clutch; • Breakdown of the hydraulic unit; • Clogging of oil channels (usually occurs when friction elements and other parts wear out); • Oil pump failure.
Very often, in an automatic transmission, one malfunction smoothly flows into another, and if the problem is not solved immediately, then soon the box will simply fall apart. It's all about the design and the principles on which the automatic transmission is based. For example, friction clutch discs wear out over time, and the products of this wear gradually contaminate the oil. These contaminants cause clogging of the oil channels and valves of the hydraulic unit, disrupting its operation, which causes poor performance and overheating of the friction clutches. Oil contamination also affects other automatic transmission systems, and if you do not immediately pay attention to this problem, you will soon have to spend money on serious repairs to the transmission.
All malfunctions, regardless of type, have common causes:
• Depletion of service life of box components or their natural wear; • Filling the box with oil other than that recommended by the manufacturer (different composition, different viscosity, etc.); • Carrying out repairs using low-quality spare parts (and this is often a conscious choice to save money); • Gearbox maintenance with an extended service interval or irregular maintenance “from time to time”; • Carrying out maintenance or repair work by a low-skilled specialist; • Features of driving style, in which the transmission and engine often operate in difficult and dangerous modes.
The occurrence of a transmission malfunction is indicated by external signs by which the problem can be judged. But a more accurate “diagnosis” can be made only after diagnostics have been carried out. Initial diagnostics of an automatic transmission are quite accessible to ordinary motorists.
Reasons for error code P0300
Even the master will not name one reason right away: identification will require a complete diagnosis of the main systems, but since the malfunction is quite typical for the 800 cc Matiz engine, the reasons are more or less known. Here are the main ones:
Problems in the power system, which usually occurs due to low-quality fuel or its complete absence. The problem appears when the filter is clogged and the pressure is low, as well as when the injectors are not functioning properly.
- Errors in the operation of the ignition system. Any element directly involved in igniting the fuel may fail. Most often the problem is caused by faulty coils and spark plugs. Information sensor malfunction.
- Problems associated with intake and exhaust. A common cause is a malfunction of the catalyst, clogged with debris. There is a possibility of problems in the valves.
- Faulty electronic components. The absence of a signal may cause an error to be displayed. There may be problems in the entire electronic unit.
Compromise or problem
A weak battery is another problem with Daewoo Matiz. Due to its compact size, which does not allow placing a full-fledged battery under the hood, the car provides the most compromise option inherited from its predecessors Alto and Tico. Despite the small capacity, it is usually enough for daily use and even in frosts down to -20 degrees and wet weather you can easily start the car. The driver will face recharging if he forgets to turn off the lights and leaves the car for several hours.
To improve this situation, there are options for installing a more powerful battery, but it is not so easy to find, like the rest of the spare parts provided for this model.
Sometimes starting a Matiz in winter is real torture!

Remove the wire tips, holding the tip, not the wire, so that it does not break, unscrew the spark plugs and check their condition.
This is how it is possible to quickly detect a problem and quickly eliminate it, if it is minor, for example, by replacing spark plugs or restoring the insulation of wires.
However, if the breakdown is serious, it is better not to get into the internal combustion engine with your own hands. The main reasons for the uneven operation of the Matiz engine. Owners of Matiz cars and Daewoo Matiz malfunctions turn to car services with complaints about the repair of internal combustion engines, so that typical methods for solving problems with engines are known. Remedy: You can hear a squealing or howling sound from the clutch housing Replace the flywheel Strong noise when the starter is running The starter is mounted on the engine with a misalignment, its fastening is loose or the cover on the drive side is broken Inspection Tighten the Daewoo Matiz connection fault with the prescribed tightening torque, see.
You can hear a squeal or howl from the clutch housing Replace the flywheel The teeth of the starter drive gear or, more often, the flywheel ring are worn Inspection after removing the starter Replace the starter or flywheel The gear does not disengage from the flywheel: Daewoo Matiz faulty ignition switch contacts can be checked with an ohmmeter.
If the voltage at the starter traction relay disappears when the ignition is turned off, remove and disassemble the starter to check. Replace the starter traction relay or starter assembly; ignition switch contact group or switch assembly, Daewoo Matiz power relay malfunctions The crankshaft is turned by the starter, but the engine does not start There is no fuel in the tank According to the fuel level indicator and warning lamp Add fuel The battery is discharged The crankshaft is turned by the starter very slowly.
The voltage at the battery terminals when the consumers are turned off is below 12V. Charge the battery; if it does not charge, replace it. Reduced battery capacity. The crankshaft turns very slowly. When the starter is turned on, a voltage of more than 0.5 V appears between the terminals of the battery and its terminals, check with a voltmeter. Tighten the terminals, clean the contact surfaces, lubricate them with petroleum jelly. Increased resistance to rotation of the engine crankshaft: The voltage between the terminals of the Daewoo Matiz battery is normal, see.
If the weather is cold, and the day before the engine was running steadily and without any extraneous noise, most likely the reason for the increased resistance to rotation is frozen oil. In this case, you can try to start the engine with a Daewoo Matiz due to a malfunction of the second battery.

The Daewoo Matiz engine runs unevenly: how to understand what is the reason?
After starting, do not allow the engine to operate at high speeds and monitor the Daewoo Matiz for malfunctions with an oil pressure lamp: If you hear extraneous noise when starting or operating the engine, check the free rotation of the coolant pump and generator pulleys.
If there is any unusual noise in the area of the block or cylinder head, disassemble the engine. Use engine oil in accordance with climatic conditions.
If the coolant pump is jammed, replace the pump cover with the impeller [B] or the entire pump [U], if the Daewoo Matiz is jammed, the fault is the bearing or generator assembly. A non-optimal ratio of gasoline and air will make starting in cold weather difficult.
Within two minutes after the engine is finally started, the computer will decide that the coolant temperature has reached 80°C. So you will have to not only start, but also warm up the engine by operating the gas pedal.
Possible engine malfunctions and methods for eliminating them Deo Matiz
Another trouble awaits the driver when the Daewoo Matiz engine heats up and the temperature is close to critical, for example, in the heat, in a traffic jam. The engine will lose power and detonate. In this case, the engine may also trip. Please note that the problem can also occur on relatively new cars. In practice, we met Matizs whose mileage was 50 thousand.
Pay attention to the air filter. If this is the problem, then the engine cannot start.
True, such a malfunction manifests itself equally on both hot and cold internal combustion engines. The most common cause is a clogged injector.
The motor and its problems
The most popular are Matiz cars with an engine capacity of 0.8 liters. A good motor in terms of service life, and this little one has enough of it. In the city, it allows you to confidently stay in the traffic. The most common problem is clogged injectors. If during inspection the car stalls or sneezes, then the problem is definitely in them, but this problem can be solved by cleaning, plus you can wash the throttle assembly, it is advisable to do this every 20,000 km.
Another common problem (50% of owners have encountered this) is that the throttle position sensor is faulty. It manifests itself in the form of floating speed and unsmooth engine operation. Solved by replacing the sensor (1500 original, 300 analogue).
After you buy a car, immediately replace the timing belt, it costs a penny on a Matiz, but if it breaks, the valves will bend, such repairs will cost a considerable amount. Then change the belt every 40 thousand km. mileage
