Where is the Kalina coolant temperature sensor located?

Optimal temperature conditions in the refrigerator and freezer

In order not to lose the beneficial properties of food during storage, it is necessary to provide any product with an optimal temperature regime.

The storage temperature of the most commonly consumed products (dairy, fresh vegetables, sausages) ranges from +2 to +6 ºC.

Food supplies are placed in the freezer for long-term storage. The normal temperature is -18 ºС, and if food needs to be quickly frozen, then -25 ºС.

Food storage table

The table below shows the recommended storage mode for the most commonly used products:

The shelf life and conditions of many products are indicated on the packaging.

Cold distribution, food storage areas

In the refrigerator, the temperature in different places is not the same and may differ by 2-3 degrees.

Due to the frequent opening of the refrigerator door, the door shelves are always a little warmer than in the refrigerator compartment. If you set it to +4 ºС, then the door may be +5+8 ºС. Door shelves store drinks, bottled dairy products, ketchups, and sauces.

Vegetables are stored in special drawers on the bottom shelf.

The temperature regime here is affected by the location of the freezer. If it is at the top, then the usual temperature is +6 ºС, if at the bottom, then it may be 1 degree less. Vegetables at this temperature can not spoil and can be stored for up to 20 days.

In new models, a separate compartment is installed, the so-called “Freshness Zone”. This is the coldest place, and the temperature in it is set within +1+2 degrees. You can store butter, cheeses, sausages, and herbs in such a chamber.

On the shelves, below and above the “Freshness Zone”, the temperature ranges from +2 to +4 degrees. This is a place for eggs, confectionery, and you can store fresh meat and fish for a short time.

Soups, main courses, and salads are stored on the middle and top shelves. In order for household appliances to serve for a long time, dishes should only be placed cooled to room temperature. The temperature on these shelves is about +4 ºС.

If you frequently use a household appliance, the temperature may be higher than that set during adjustment. If you do not open the refrigerator doors for a long time, the temperature becomes the same on all shelves.

Checking the coolant temperature sensor and its circuits

With the ignition off, disconnect the engine management system wiring harness block from the coolant temperature sensor.

The block terminals “A” and “B” are marked on its body. By connecting the tester probes to terminal “B” of the block and to engine ground, with the ignition on, we measure the voltage of the sensor input signal circuit.

The device should detect a voltage of 4.8-5.2 V. If the voltage does not match, check the serviceability of the circuit (open and short to ground) between terminal “B” of the wiring harness block and terminal “39” of the controller. If the circuit is OK, the controller is faulty.

By connecting the tester probes to terminal “A” of the block and to the “ground” of the engine, we measure the resistance. If the sensor grounding circuit is working properly, the device should detect a resistance of less than 1 ohm. The reason for the increased resistance may be an unreliable connection in the blocks connected to the sensor or to the controller. To check the sensor, disconnect the engine control system wiring harness block from it. Using a tester, we measure the resistance of the sensor for two values ​​of coolant temperature - a non-heated and a warm engine. We compare the obtained values ​​with the control ones, see the table:

Freezer

Typically, the freezer has 3 shelves with spacious drawers for storing food. If there is a separate mode adjustment in the freezer, then it is set depending on the load.

With an incomplete load, you can keep it at -16 ºС , with a full load or when you urgently need to freeze the product, do -25 ºС. The average optimal temperature is -18 ºС.

The approximate placement of food in the freezer compartments is as follows:

1. Top drawer. Products that are often used: minced meat, dumplings, semi-finished ready meals.
2. Middle drawer. Here you can store provisions that require long-term storage: frozen meat and fish.
3. Bottom drawer. Provisions that are rarely used: frozen vegetables, mushrooms and other products for freezing.

Kalina 2

Lada Kalina of the second version, by and large, differs from its predecessor only in complete restyling. The exterior has undergone many changes as well as the interior design, but the interior has remained the same. “Kalina 1 temperature sensor” remained in its place, although it was supplemented by a fellow from the salon, proudly calling itself “Kalina 2 temperature sensor”. It came along with a new air conditioning system.

Lada Kalina second version

In general, the new car claims to be a class of car higher than its predecessor, and in terms of comfort we can say that the claim is justified. Inside, Kalina 2 has the usual 8 and 16 valve engines. The presence of the same number of valves in the predecessor does not yet cause alarm, but suspicions begin to creep in.

Further more, the same rear drum brakes, stiff suspension, problems in the cabin. However, there are also many corrected problems with Kalina 1. As for the sensors, there is almost complete interchangeability between Kalinas.

As a result, if you decide to replace the first version of the car with the second, but only recently purchased a new high-quality part for it, do not rush to get upset about it. It will almost certainly fit a new car when the time comes.

How to measure the temperature in the refrigerator

Measuring the temperature in the refrigerator and finding out whether it meets the recommended food storage standards is an important task for every user. For this purpose, use an ordinary household thermometer with a measurement scale from -40 ºС, so that you can measure in the freezer.

The measurement is carried out in the following sequence:

1. Remove all food from the refrigerator, with the exception of perishable items.
2. Place the thermometer on the central shelf.
3. Close the refrigerator door for 8 hours so that warm air when opening the door does not affect the readings.

In the freezer, measurements are carried out in the same way, but there is no need to remove food from the freezer.

If you want to find out the maximum negative minimum of the device, then you need to set the mode regulator on the case to the most extreme position and after 8 hours look at the thermometer readings. The nominal value should be about -24 ºС.

Signs of DTOZH malfunction

The coolant temperature sensor affects engine starting and operation. Here are some symptoms that indicate that the sensor may be faulty:

• poor engine starting in cold weather;
• increased fuel consumption;
• poor exhaust on a cold engine;
• Problems with the engine cooling fan.

The coolant temperature sensor is located in the thermostat housing; it is number 14 in the diagram.

To change the DTOZH with your own hands, you should:

1. Drain the coolant (car mechanics do not drain it);
2. Disconnect the connector with wires;
3. Unscrew the sensor (key “19”).

Installation is carried out in reverse order. To eliminate the leak, replace the copper washer or apply a heat-resistant sealant to the threaded part of the sensor.

How to set the temperature in refrigerators from different manufacturers

The temperature regime in the refrigerator is controlled using a regulator . Depending on the product model, regulators are mechanical or electronic.

Manufacturers also produce equipment equipped with two compressors with separate control of the mode in the freezer and in the cooling chamber.

Electronically controlled models

Units on which electronic temperature control devices are installed allow you to regulate the operating mode of the product and temperature with an accuracy of 0.1 ºС.

The control buttons and display are located on the outside of the refrigerator door. The display shows the actual temperature inside the device.

This control method is very convenient; you can easily set the optimal cooling and storage mode for food. You will always be aware of what is happening inside the refrigerator. All information about this will be displayed on the display screen.

Mechanical Refrigerators

Depending on the model, the control knobs are installed on top of the door, or inside the refrigerator on the right wall. Setting the required temperature mode is done by moving the regulator knob clockwise.

Be sure to read:

In such household appliances, it is not possible to set the temperature inside using an electronic display, so the position of the regulator knob is determined experimentally. Manufacturers recommend setting the handle to the middle position, believing that the temperature inside will be the most optimal.

But the cooling mode is affected by the load on the appliance with products and the ambient temperature. Therefore, if this is not enough for normal cooling, the knob can be turned 1-2 notches to the right. True, this will increase the operating time of the compressor.

Refrigerators with separate control modes

In refrigerators with separate control modes, two thermostats are installed for the refrigerator and freezer compartments. Setting the required temperature in the chambers can be done using the regulator knob or by pressing the regulator button.

The freezer has a super cooling mode, in which the temperature drops to -25 ºС, and then after a certain period of time returns to the optimal -14 ºС.
