VAZ 2114 misfires reasons

How to eliminate common causes of failure of the daewoo matiz ignition system?

Daewoo Matiz.
The engine does not start - reasons, troubleshooting Frequent reasons why the 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.

It happens that the spark plug is fine, but there is still no spark. Here you need to check the armored wires and even the ignition coil. By the way, the capacitor on the ignition coil may fail. It is advisable to have a spare one with you (it costs pennies).

There is no spark on the center wire. You can check this way: disconnect the central wire from the distributor cover and unscrew the tip. After this, you need to turn the key and keep the end of the wire near the metal. There must be a good spark. Problem with the ignition switch. It happens that some terminal falls off in the lock itself. Especially on older cars. Naturally, you need to know where to put it again. In addition, fuses may blow. Therefore, it is always worth having a set of spare ones in your car. It is inexpensive, does not take up space, and a blown fuse can not only be the reason why, for example, turns do not work. It’s worse when the internal combustion engine does not start for this reason.

Other possible faults

Problems with the starter solenoid (traction) relay. The most common problem here is burnt nickels (can only be seen when the device is disassembled). In addition, contacts may become unsoldered from them. In this case, when you turn the ignition key, only a quiet click of the starter relay will be heard, and the retractor will be silent. If it is working, it will make a clear metallic click. It is unlikely that it will be possible to repair it on the road. Although the repair is inexpensive and relatively simple.

The starter has failed. If, when the car engine starts, a click is clearly heard when you turn the key, but the start does not occur, and the battery wires get hot or even smoke comes from them, then the starter needs to be replaced. The ignition is set incorrectly. This happens after engine repair. In this case, you should contact a specialist.

The distributor is filled with water or simply wet. This happens, for example, when driving through large, deep puddles. In this case, the spark will simply go away (break through) and not reach the spark plugs. The solution is simple: wipe the distributor and let it dry. The engine may not start because it is jammed. The signs and causes of a wedge are a broad topic that will be difficult to consider within the scope of this article. In addition, for various reasons, piston rings, etc. may become completely stuck.

So, as follows from everything that is written above, answering the question of why the engine does not start is not so simple. All reasons can be divided into three main groups: - problems with fuel supply; -electrical problems; -problems with mechanics (that is, with the engine itself).

It is recommended not to forget to regularly carry out scheduled maintenance, additionally check the engine and attachments before a long trip, charge the battery in a timely manner and fill the gas tank with only high-quality fuel.

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.

DAEWOO Matiz: 0.8 liters of trouble. Part 2

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.

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.

VAZ 2114 misfires

A client arrived with the following complaints: the check engine light regularly turns on after driving on the highway, and this happens for no noticeable reason; the car immediately starts to drive worse after the light turns on. Using the diagnostic adapter, he determined that there were misfire errors in one of the cylinders. The engine of the VAZ 2114 has been shaking at idle for a long time, about a year. The client came to terms with this a little and initially called me with a request to reflash the car, but I redirected his train of thought to perform diagnostics: it is impossible to repair a faulty car.

Before conducting diagnostics, I always ask what was done to the car at least in the next two to three weeks. Sometimes the information obtained during such inquiries can lead to the right conclusions when troubleshooting.

The range of work that was performed on his car by other craftsmen: spark plugs were changed, explosive wires were not changed (switched from another car, it didn’t help), injectors were changed about a year ago, the fuel pump was changed relatively recently along with both filters, since he didn’t need any After checking the pressure, the service station said that it was only 2.5 bar. The blood pressure returned to normal after the work. The timing belt and pump were recently replaced due to a leaking pump. The valves were adjusted two months ago. He thought that might be why he was shaking so much.

Connected a scanner to read saved errors and analyze parameters:

According to the scanner, there were errors in misfire in cylinders 1, 2, 3. According to the parameters issued by the scanner, there were no complaints about the car’s performance: air consumption, fuel correction, fuel injection ratio and injection time were normal.

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.

Misfire in a VAZ Priora cylinder, signs, causes

Almost every motorist has encountered the problem of flammable mixture ignition. There can be many reasons for problems when igniting a combustible mixture, but they all lead to a drop in engine power and the shutdown of one or a pair of cylinders. On cars with an ECU, when the engine malfunctions, errors appear that indicate problematic parts of the unit. If misfires occur, you should urgently contact a service station to troubleshoot the problem.

Unstable engine operation and shaking at idle, loss of power and increased fuel consumption, the appearance of a “Check” error on the instrument panel, jerking of the car and other troubles can be caused by a misfire in the engine cylinder.

There is nothing wrong with this, because if the engine runs but does not pull, it means that not everything is so critical.

Next, we will talk about how to properly diagnose a car and identify the cause of the malfunction.

There can be many reasons for the problem; even professional mechanics spend more than one hour to identify its source.

The main reasons for misfire in cylinders 1, 2, 3, 4 can be:

The ignition coil or module has failed;
Inoperative fuel injector, clogged due to low-quality gasoline;
Incorrect spark plug gap, which can lead to poor sparking;
The spark plugs are flooded or carbon deposits have formed on them;
Breakage of high-voltage wires, increased resistance (non-standard ones are installed), oiliness of contact points;
A high-voltage wire has fallen off (often happens on Lada Kalina and Granta);
On an 8-valve engine, the timing belt may jump (during replacement, an error was made due to marks or as a result of excessive wear);
On a 16-valve engine, the hydraulic compensators are not working correctly;
Air leak (can be anywhere);
The compression in the engine cylinders has dropped or is different (applies to cars with high mileage);
Low pressure in the fuel rail as a result of reduced fuel pump performance.

If your car is equipped with a modern control unit, then this greatly simplifies troubleshooting; otherwise, you will have to use time-tested old-fashioned methods.

By connecting the computer to the car, you can find out in which cylinder, 1, 2, 3 or 4, and for what reason there are misfires, for example, the ignition coil or one of the injectors has failed.

But in any case, before going to a car service center, you need to check the condition of the spark plugs, injectors, high-voltage wires, how the exhaust system works, and whether there is smoke from the exhaust pipe.

The scanner is connected to a special connector, which can be located in different places in each car model, but it has one function: diagnostics.

Next, error codes are read from the control unit and decrypted.

For example, VAZ 2110, 2114, 2115, Lada Kalina, Priora, Granta cars have the following error codes that are characteristic of misfire:

P0300 - a large number of misfires;
P0301, P0302, P0303, P0304 – misfires in cylinders 1, 2, 3 and 4, respectively;
P0300 - a large number of misfires in a random order;
P0301, P0302, P0303, P0304 – misfires were detected in 1, 2, 3 and 4, respectively;
P0363 – see point 4, the fuel supply to the problem cylinders is stopped;
P1301, P1302, P1303, P1304 – respectively, misfires dangerous for the catalytic converter were detected in cylinders 1, 2, 3, 4;
P0300, P0301, P0302, P0303, P0304 – detection of misfires affecting the toxicity of exhaust gases;
P0363, P1301, P1302, P1303, P1304 – the same as in point 7, but affecting the catalyst;
P0351, P0352, P0353, P0354 – open circuit in the ignition coil in the control circuit 1 (1-4), 2 (2-3), 3, 4;
P2301 P2303 P2305 P2307 - short to on-board network in the coil in the control circuit of cylinders 1 (1-4), 2 (2-3), 3, 4;
P0201, P0202, P0203, P0204 – respectively, open circuit for controlling injectors 1,2,3,4;
P0261, P0264, P0267, P0270 - short circuit of the injector control wires to the body, respectively, in the 1st, 2nd, 3rd, 4th center;
P0262, P0265, P0268, P0271 – the same as point 12, but only to the on-board network;
P1500 – electric fuel pump relay, wire break.

Let's look at misfires using the example of the VAZ 2109, 2110, 2114, 2115, Kalina, Priora, Granta models.

The computer generated error P0303 (misfire in 3rd crank).

First you need to understand how the ignition coil works. It consists of two small coils, pins 1 and 4 are connected to the first, and pins 2 and 3 to the second.

Those. during operation, voltage is simultaneously supplied to the first and fourth cylinders or to the second and third.

We have misfires in cylinder 3. Remove the wires from 2 and 3 and swap them.

High-voltage wires are tested by checking their resistance. To do this you need a regular multimeter.

Set the resistance measurement mode to 20 kOhm.

In our case, we check the third wire. If the device shows numbers within the range of 3.5 - 10 kOhm, then the wire resistance is considered normal, otherwise it changes.

Next we check the coil. For this you also need a multimeter.

We measure the resistance between 1 and 4 and 2 and 3 coil terminals. Readings of 10 kOhm, or around this figure, are considered standard.

Next we check the resistance between each terminal and ground. In this case, on the contrary, the multimeter should show 1 (infinity).

If resistance is shown at one of the terminals, it means that its insulation is damaged and it is connecting to ground. Accordingly, the required voltage will not be supplied to form a spark.

Next, we check the resistance between the central terminal of the ignition coil and the housing (ground). It should also be equal to infinity, i.e. 1.

A resistance of 2 ohms is considered normal (-). There should be no break between the extreme terminals.

Next, check the condition of the contacts on the coil itself and on the wires; they tend to oxidize over time, especially if your region of residence has a humid climate.

If the error remains in cylinder 3, but the coil and high-voltage wires are in good condition, we check the spark plug.

The easiest option is to remove the spark plug from the working cylinder and swap them.

If the error then transferred to another cylinder, then most likely the issue is in the spark plug.

If nothing has changed and the error remains, then check the injectors.

Next, check the injector power supply circuit. Also, the injector may become clogged and not supply the required amount of fuel, which can cause misfires. Therefore, you will have to clean the injectors.

If after all the above checks the misfires have not disappeared, you need to check the valve clearances.

The valves should not be tightly clamped, as this will lead to their incomplete closing, and this, in turn, will lead to a decrease in compression and compression ratio in the cylinders and this will cause misfires. Also, if you press too hard, the valve may burn out.

If we talk about foreign cars, they also have special error codes indicating misfires.

Let's look at the error codes using the example of a BMW x5 e53 motor M54 3.0 USA (if the country of manufacture is different, the codes may differ).

As a rule, these errors are associated with problems with mixture formation, sparking and decreased compression:

Problems with the ignition coil - errors 101, 202, 303, respectively, cylinders 2, 4, 6;
Injector circuits – errors 505, 606, short circuit, open circuit;
Injector - codes 2216, 2317, 2418, 3321, respectively, refer to cylinders 3, 6, 4, 5;
Malfunction of the idle air control valve - 271V;
Ignition coil - errors 291D, 301E, 311F - 1, 3, 5 ts.
Problems with the camshaft position sensor - error code 6541;
Fuel pump relay - error code 6945;
Problems in the ignition system - 210D2;
Failure of the idle air control valve as a result of its mechanical damage - 211D3;
Poor quality fuel mixture - 227E3 for cylinders 1, 2, 3 and 228E4 for 4, 5, 6.
Cylinder misfires - 238EE in the first, 239EF in the second, 240F0 in the third, 241F1 in the fourth, 242F2 in the fifth, 243F3 in the sixth;
Weak flow in the air mixing system - 245F5 cylinders 1, 2 and 3. Error code 246F6 - 4, 5 and 6 cylinders.

Also, the reasons for misfire in a BMW x5 e53 M54 engine can be:

Air leakage, for example, the throttle corrugation or other suction points are torn;
The mass air flow sensor has failed;
Incorrect operation of hydraulic compensators;
Timing chain stretching and ignition timing deviation;
The high-voltage coil of one of the cylinders has failed (rearrange it to check);
The problem is in the flow meter, remove the terminal block from it and see how the engine works;
If the BMW x5 e53 has misfires after 3000 rpm, then check the DIS (DISA - installed inside the intake manifold, designed to suck in the fuel mixture through separate pipelines);
A failed membrane is responsible for the mixture of gasoline and air;
Other reasons.

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.

Fault diagnosis

The ignition of a VAZ 2114 is diagnosed according to the following scheme: the power plant check lights up on the panel; during testing, error P0300 may light up. This means:

problems in the first - P0301;
problems in the second - P0302;
problems in the third - P0303;
problems in the fourth - P0304, etc.

Error code 0304 - error in the fourth

Of course, there are a lot of factors that cause the air-fuel mixture to not ignite, and they are different.

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.

What can multiple misfires lead to?

Single misfires are only a signal to the owner of a VAZ 2114 about problems with the engine.

Numerous incidents entail the following consequences:

As a result of misfires, unburnt fuel will enter the catalytic reduction system. Because of this, the converter will overheat and fail.
With repeated misfires, some of the gasoline will enter the lubrication system through the walls of the idle cylinder. Oil diluted with gasoline will lose its properties and will not be able to provide high-quality lubrication of loaded engine elements.
All these factors can lead to engine failure and the need for expensive repairs.

Cabin mounting block

In the Matiz interior, the mounting block is located under the dashboard, on the left side (above the driver’s left knee). The most convenient way to operate it is to sit in the passenger seat, lie down on the driver’s seat and tilt your head back or sideways towards the pedals so that you are facing the mounting block, then the mounting block and the fuses in it will be visible.

Or you can open the driver's door, place something on the threshold, sit next to the car and look under the dashboard. It’s not very convenient, considering that the car is mainly for women, but what can you do, it’s what it is.

Interior fuses

F1 (10 A) - instrument panel, sensors and warning lamps, immobilizer, clock, alarm

. If the sensors on the dashboard have stopped showing and the backlight has disappeared, check the panel connector on the back side, it may have popped out or the contacts have oxidized. Also check the wires and connectors on the back of the mounting block for this fuse.

When you turn on the ignition, the immobilizer icon on the panel lights up - this means that it is looking for a chip key. If you successfully find the key, the lamp goes out and you can start the car. To add a new key to the system, you need to flash/train the ECU to work with the new key. If you do not understand electrical equipment, it is better to contact a car service. If the car is not running, you can find and call a mobile electrician.

F2 (10 A) - airbag (if equipped)

F3 (25 A) - electric windows

. If the power window of one door stops working, check the integrity of the wires at the bend point when opening the door (between the body and the door), the control button and its contacts. It could also be a problem with the window lift mechanism. To get to it, remove the door trim. Check the serviceability of the motor by applying a voltage of 12 V to it, the absence of distortion of the glass in the guides, the integrity of the gear and cable (if the window lifter is a cable type).

Design features

The standard Matiz has front-wheel drive and a 5-speed manual transmission. But there are also modifications with automatic transmission. The front suspension uses MacPherson struts, and the rear suspension uses a rigid axle with rubber-metal bushings. Due to the somewhat archaic suspension design, the minicar does not behave well on the road. When cornering, the body rolls heavily, and driving at speeds over 120 km/h is very dangerous.

The M100 model earned only three stars in crash tests according to EuroNCAP. Unfortunately, little has changed after modernization.

Typical problems and malfunctions

One of the weak points of the Daewoo Matiz is the suspension. Ball bearings of levers and shock absorbers wear out relatively quickly, and due to corrosion of threaded connections, repair difficulties arise. Wheel bearings are also not very durable, and soon begin to howl loudly.

Corrosion is cruel to the exhaust system, especially at the junctions of its elements. This drawback applies to almost all vehicles used in the city. With age, rust begins to “affect” the body. The first foci of the “red disease” are found on the wheel arches, hood, sills and at the bottom of the doors.

The interior is not impressive, and the quality of the plastic is scary.

One of the most common problems is a broken windshield. The reason is corrosion of the area located under the glass. As a result, the load on the glass increases and it breaks.

There are also problems with the clutch. Most often, the culprit is the cable, which over time rusts, jams and ultimately breaks. Sometimes synchronizers or gear selection mechanisms fail. Rear brake drums are another component that may require repair.

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.

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.

Daewoo Matiz & Ravon R2 Club

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.

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.
