Characteristic Dzten.
So that nozzles, as well as other elements injector 16 or 8 valves operated in normal mode, the ECM reads readings from many devices. At first glance, it may seem that - this is not particularly important for the engine "Dozens" device, but it is not. As the devices are included, where there are pointers and what functions they perform - to begin with, we suggest familiarizing yourself with the answers to these questions.
Location, functions and principle of operation
Coolant temperature sensor is electronic deviceIn essence, this is a semiconductor resistor with a negative coefficient. The resistance of the controller changes in accordance with the state ambient. The device is designed to control the temperature during circulation consumables in the cooling system VAZ 2110 with further transmission of the data obtained on dashboard. In addition, this device is also responsible for the extra start of the fan. In VAZ 2110, Dzuz is in the head of the BC Motor. Many car enthusiasts are confused by calling his VAZ 2110 fan switching sensor, but it is incorrect.
The design of the coolant controller on the VAZ 2110 is quite simple. The bigger the temperature effects will be on the device, the less will be its resistance. The principle of operation lies in the transmission of the signal from the device to the ECD unit, which, based on this data, is adjusted combustible mixture In the cylinders of the power unit. Until that moment until the motor warms up, a more enriched combustible mixture will flow into the cylinders.
Ways to check for performance
There are several ways to diagnose antifreeze temperature controller - visual and with a tester. Before arm with a multimeter, you should carefully examine the device's housing. If there are traces of corrosion, deposits or damage, this suggests that the regulator needs to be replaced.
As for the verification of the multimeter, this procedure is as follows:
- First, the device should be removed, for this you just need to find the place of installation, turn off the power and unscrew the device. Next, you will need a container that the refrigerant should be pouring.
- The next step is the heating of the capacity after you put the DPET into it. But before this it should be connected to the tester shoes. Please note that when diagnosing you should definitely know the level of heating temperature of the fluid, it will make it possible to determine the performance of the controller. Capacity is heated, and you will need to compare the obtained indicators with those that are specified in the table. The table itself is shown below.
- In the event that the temperature level does not correspond to the nominal resistance rate or vice versa, this indicates a device malfunction. A cooling fluid temperature sensor signal level also speaks of its breakdown. There are cases that the problem when the values \u200b\u200bare higher than the optimal can be solved by cleaning the surface of the device, but such measures will usually help if the deviation of the indicators is minor (author of the video about independent diagnostics Dzh - channel device and repair of the car).
Possible malfunctions and ways to eliminate them
The car owner can inform the following symptoms about the failure of the DR
- The quality of the exhaust gases is too low, which is associated with a disruption of a combustible mixture in the cylinders.
- Increased fuel consumption, and significantly.
- There were problems in the work of the power unit. Dynamics vehicle It may decrease, the engine power as a whole will also deteriorate.
- An error combinations may appear on the tidy, and the ECU can send a signal to the shield about the need to verify the performance of the motor.
- The power unit has become harder to run.
If the first signs are detected, many motorists immediately drive their cars into the garage or a hundred to change the controller. In practice, the symptoms of Dzhop problem are often associated with damage to the electrocups and a bad contact of the device with onboard network car. Therefore, if you encountered a similar problem, first of all we recommend checking the condition of the wiring.

DVT removal in VAZ 2110
Salon temperature sensor VAZ 2110 is used to control the temperature parameters in the car. This controller is also a transmitter associated with ECM. In the cold time, the VAZ air controller transmits information on the ECU, which contributes to the optimal circulation of the air flow through the cabin car. As in the previous case, the device malfunction can be due to problems in the operation of electrocups, so it will not be superfluous to check and wiring if the controller does not turn on.
To replace the cabin, you need to perform the following actions:
- Machine you need to put on parking brake. Disconnect the battery.
- Using a flat tip screwdriver, you need to push the body of the device from the installation site.
- First, the upper part of the DTVS is removed, it will allow to provide a more convenient dismantling of the controller. When the device is dismantled from the clamps, act neatly because you still need to turn it off from the wiring (two connector). First, the wiring is turned off, then the DTVS itself is retrieved.
- As for the installation, this procedure looks likewise, only carried out in the reverse order. After installation, it is necessary to diagnose the device's performance.
The full operation of the engine depends on the set of factors, in particular from the good state adjacent to it. So that the motor does not overheat, you must constantly monitor the cooling system. The main function in it performs the engine.
Main functions of the engine cooling system
The engine during operation reaches critical temperatures that can not be out of order in the car. In order not to happen like such incidents, you need to take off the excess heat from its details. This feature provides a cooling system, which is also:
- Accelerates the engine heating to operating temperature.
- Heats air in the cabin.
- Cool exhaust gases.
- Cool lubrication system.
The cooling system is three types:
- Liquid - cooling occurs due to liquids (toosol, antifreeze, water).
- Air - cooling occurs by blowing air.
- Combined - mixed type.
Most cars, including VAZ, are equipped with a liquid cooling system using Tosola. It includes:
- Radiator with fan.
- Radiator stove.
- Cooling shirts.
- Water pump.
- Expansion tank.
- Connecting nozzles.
- Cooling fluid temperature sensor VAZ 2110.
Cooling fluid runs in the system two circles:
- Small circle. This is the initial movement of the fluid, which is not yet involved in the radiator. Passing a small circle, water or toosol provide engine warming.
- By a major circle, the liquid begins to go when the engine temperature reaches hundred degrees. The thermostat is revealed, and Tosol begins to enter the radiator where it is cooled. If he does not have time to cool with further heating, a fan is entered into operation, which additionally cools and the radiator itself, and the engine itself.
Why do you need any sensors?
Cooling fluid temperature sensor VAZ 2110 - not the only automotive sensor. There is a huge number of all the devices with which the engine control is made.
All sensors perform the function of receiving information about the status of the control object. Then this information is transmitted to the controller. He, in turn, plans or adjusts the work of all systems in the car.
For example, air in the cabin is needed to control the climate inside the car. When it is cold - the stove turns on its signal, and when it is hot - air conditioning. Thus, in addition to ensuring a comfortable stay, the frost is also prevented.
Speed \u200b\u200bsensor is required to control the car on idling. Position sensor throttle valve - For the correct calculation of the fuel and air mixture. And thanks to the driver always knows how much gasoline it remains in the tank, and may not worry about what will not reach the refueling.
The cost of such devices is the most diverse - from 150 rubles and up to several thousand. One of the most expensive sensors mass flow air. The price of some of its models reaches 7,000 rubles.
Coolant temperature sensor (VAZ)
This device is a semiconductor resistor with a negative temperature coefficient. It is installed in the engine cooling system on the thermostat housing. Resistance depends on temperature. At low temperature, the resistance is high, and vice versa.
The signals of this device are coming to the electric motor control unit. ECU based on readings adjusts the feed fuel mixes. If the engine has not yet warmed, the enriched mixture is supplied.
When the sensor is defective, incorrect temperature readings are fed to the computer, as a result of which the engine begins to overheat and lose its functionality. Therefore, with the replacement of the device it is better not to delay.
Cooling fluid temperature sensor 2110: fault signs
In order for the sensor readings to be correct, it needs to be properly installed, namely, next to the thermostat case, while its tips should concern the coolant. If the instrument indicators are inaccurate, the first and essential reason may be incorrect installation. False testimony will be and then when the coolant is located on a critical low level.
One way or another, the problems of the sensor can be judged by the following features:
- Low quality exhaust gases.
- Increased fuel consumption.
- The deterioated composition of exhaust gases.
- Low engine handling.
- Problem code or flashing engine overheating lamp.
- Difficult launch.
Before you "sin" to the sensor, check the condition of the wiring and connectors. Often, breakdowns are connected only with wires.
The external diagnosis of the sensor can also talk about its non-working condition - corrosion and different deposits make it unsuitable. The device resistance is checked with a special device - voltmeter or multimeter. The thermistor sensor in the cold state shows the voltage of 2 V, in the hot - 0.5 V. Other readings say that it is not suitable.
Change the sensor with your own hands
Despite its size and simplicity, performs an important role in cooling the engine. It happens that its testimony is inaccurate. In this case, the device should be changed.
Replacing the coolant temperature sensor is performed in the following order:
- Dry liquid, better all.
- Disable battery.
- For practicality, remove the air filter.
- Disable the ignition system and disconnect the sensor connector.
- Using the key (on 19) you need to unscrew the sensor and remove it along with the sealing ring.
- Installation is made in reverse order.
Such device is a relatively inexpensive car spare part. The new coolant temperature sensor (2114, 2110, 2109, as well as other models of the vase) can be in average for 200 rubles. The failure of this device is widespread. Absolutely any driver can cope with the replacement process. The sensor is small, but very important item. If he starts to "clutch", with repair it is better not to delay - herself is more expensive!
A few words finally
Oh neither twist, the functionality of the engine depends on the established operation of all system sensors. After all, with their help, you can learn about the status of a certain part and correct its work. Cooling fluid temperature sensor 2110 - one of the main appliances. Its malfunction can lead not only to increased fuel consumption, but also to overheating the engine, which is further fraught with a breakdown. A new motor, compared to the sensor, is a whole financial condition!
Are the most important elements common systemwhich is responsible for the stable operation of the power unit equipped with fuel injection. The "Dozens" injectors collect information about the state of certain parts of the engine and send them to the electronic unit Motor control (ECU), which, after analyzing all data, adjusts the operation of the power unit.
Actually, you ask why such difficulties? The reason is that the injector motor VAZ 2110 is much more effective than the carburetor fellow. More power, less fuel consumption, stable operation, high reliability, all this is characteristic of "dozens" with good electronics. A malfunction of one or more sensors necessarily leads to the failure of the engine or its unstable operation. Today we will tell about in detail about vAZ 2110 injector sensorsfrom which depends normal work Motor.
Mass flow sensor VAZ 2110
VAZ 2110 air sensor or mass flow sensor is located between the casing air filter and rubber nozzle. Actually, under the hood, dozens find it is not difficult, since the air sensor is located in the most prominent place. In the photo assembly, he looks like this.
Air sensor measures the number of past air, thereby assessing its volume. Immediately say the air consumption sensor is very sensitive and even a few dust or elevated humidity can output. It is worth considering it when removing or replaced.
The principle of operation of the VAZ-2110 air sensor is next - inside there are heating elements, which are cooled by the stream of air passing by air. The more energy is spent on the heating of these elements, the greater the volume of air passes by. Thus, the sensor and calculates the mass consumption of fuel.
Incorrect operation of the mass flow rate of the injector of the VAZ 2110 fuel consumption usually leads to an increase in fuel consumption, power drop, unstable operation and poor launch. Because of this sensor, the engine may simply stall on idling. The reason is simple, the electronic engine control unit taking incorrect data from the air sensor begins to feed incorrect commands to form a working mixture. A mixture of air and gasoline that burns in the motor cylinders can be very enriched or very dining, which leads to abnormal operation of the injection force unit.
VAZ 2110 throttle position sensor
The throttle position sensor of the VAZ 2110 injector is located directly on the throttle node. We offer for clarity photos where the sensor can be seen without difficulty.
This sensor responds to pressing the gas pedal by the driver, feeding the signal to the electronic control unit, thereby increasing the amount of fuel injected through the nozzles. That is, the sharper you click on the gas pedal, the more fuel in the engine will be injected. The throttle position sensor is quite reliable because it is mechanically connected to the valve axis.
It is possible to determine the malfunction of this sensor using a conventional tester, which should show voltage changes when you click on the gas pedal. When the flap is closed, the output voltage is usually from 0.3 to 0.7 watts. If you press the gas "to the floor" voltage increases to 4 W. The sensor malfunction can sometimes be determined without any testers, let's say if during overclocking the car begins to move the jerks or an abnormal failure occurs, then the problem is most likely in the throttle position sensor.
Cooling fluid temperature sensor VAZ 2110
The VAZ 2110 injector temperature sensor performs two basic functions - in case of overheating of the motor, it turns on the cooling radiator fan, and in the case of a cold start of the engine gives a command to enrich the working mixture, which would not be a motor in the cold. IN carburetor enginesThis feature is executed by the so-called "sample", which opens the flap to increase the air supply. In the event of a malfunction of the temperature sensor, problems with a cold engine start are starting and an overheating unit is overheating if the fan does not turn on during. So this VAZ 2110 sensor is very important for stable work engine Photo sensor Next -
The principle of operation of the coolant temperature sensor is as follows - with a change in temperature, electrical resistance begins to change. The lower resistance, the higher the temperature. Check the performance of the sensor can be armed with a thermometer, a container with hot / cold water and a conventional electric probe. A good temperature sensor shows about the following values \u200b\u200b-
- At a temperature of 100 degrees, the resistance is 180 ohms
- At a temperature of 80 degrees, the resistance is 330 ohms
- At a temperature of 60 degrees, the resistance is 670 ohms
- At a temperature of 30 degrees, the resistance is 2240 ohms
- At a temperature of 10 degrees, the resistance is 5670 ohms
Find the coolant temperature sensor under the hood of injector VAZ 2110 is possible between the engine and the air filter casing, it is screwed into the intake nozzle of the cooling system.
Detonation Sensor VAZ 2110
The detonation sensor of the VAZ 2110 injector is located on the cylinder block. The task of this device transmit a signal of the ECU on detonation. The electronic control unit in accordance with the software algorithms rebuilds the operation of the engine (changes the ignition advance angle) to reduce the negative impact of detonation. Initially, a resonant sensor (piezoelectric) was installed on the VAZ 2110, but then a more advanced broadband (piezoceramic). Photo of both types of sensors below.
Actually, the stronger detonation, the stronger the sensor displays the AC voltage on the ECU. It is possible to check the performance of this sensor, it is quite simple, sufficiently knock on the core of the sensor. In this case, it is necessary to connect a tester to the sensor outputs, which must record voltage jumps.
Oxygen sensor or lambda probe VAZ 2110
The oxygen sensor of the VAZ 2110 injector or lambda probe is installed on a graduate manifold. The task of the instrument to track the composition of the exhaust gases and the presence of oxygen there. This information helps the electronic control unit (ECU) to adjust the composition of the working mixture, it helps not only more efficiently burn fuel, but also improve exhaust environmental friendliness. When using the eaten gasoline, the oxygen sensor is incorrect. Photo sensor Next.
If the sensor fails, it causes increased flow Fuel and increasing emissions. The most interesting thing is that if there is an exhaust gas catalyst in the system of exhaust gases of oxygen sensors or lambda probes already two. The second is for a catalytic neutralizer, it helps to make the car even more environmentally friendly.
VAZ 2110 speed sensor
The VAZ 2110 injector speed sensor is installed on a gearbox, more precisely on the output shaft of the speedometer. If the sensor is defective, this can lead to the fact that the car in some cases can sulk at idle. When the arrow of the spirometer starts abnormally (jumps) to move on the instrument panel, it should alert you. After all, this may indicate a speed sensor fault. The sensor itself is as follows, look at the photo.
The principle of operation of the Speed \u200b\u200bSensor "Dozens" is based on the Hall effect, when the gearbox is rotated, the sensor transmits a pulse signal. The higher the rotation speed, the greater the frequency of the pulse signal. Thus, the vehicle speed is measured. The VAZ-2110 was set by the sensors of two types, one has a square connecting block, another round.
Crankshaft Sensor VAZ 2110
Position sensor crankshaft The injector of the VAZ 2110 is quite important, since without it the start of the engine is not possible. Any malfunction leads the ECU "dozens" or "brains" of the engine into a stupor. The sensor monitors the position of the camshaft (and therefore the pistons in the cylinders) in real time and allows you to make the ignition candles work on time. A signal comes to the candle from the ignition module, which comes the upper point of compression in the cylinder and it is time to "light up" a spark. The sensor itself schematically looks like in this picture -
This is a small electromagnet that catches the position. gear pulleywho rotates close by. On the pulley 58 of the teeth, which create electromagnetic perturbations. Actually for injector EngineThis is the main and most important sensor.
Sensor Phase timing VAZ 2110
The phase sensor of the VAZ 2110 injection phase phase was installed not on all the "dozen" engines. Initially, they were put on 16-valve. Then, when environmental norms tightened in our country, this sensor began to appear on all injectors, even on 8-valve. The principle of operation of this sensor in determining the position of the camshaft, and therefore obtaining information about the position inlet valves. This information is necessary for the timely injection of fuel injectors to a certain cylinder. The sensor failure leads to the enrichment of the working mixture and the unstable operation of the engine. This sensor is installed at the top of the GBC motor. Picture of the phase sensor of the VAZ 2110 gas distribution below.
I would like to note that this article will be useful not only to the owners of the VAZ of the tenth family, but also the happy owners of other injection machines. After all, the principles on which injection force aggregates work are largely similar, especially for sensors.
Cars are equipped with a multitude of sensors controlling the condition of all car units. One of the most important sensors is a temperature sensor located in the engine compartment.
On the VAZ 2110, the replacement of the temperature sensor is a responsible process. Replacing the VAZ 2110 temperature sensor in this article is carried out completely with your own hands.
What is this device
Despite the importance, relatively simple, it controls the condition of the coolant in the shirt of the cylinder block. It reports changes in temperature, passing this information to the electronic control unit.
The device is a thermistor in which the electrical resistance is reduced with an increase in temperature.
The temperature sensor readings affect many engine systems and motor performance. Therefore, it is necessary to constantly monitor the serviceability of the sensor and when it is discovered to replace it immediately.
The defective sensor is distorted by information entering the electronic control unit, which can lead to great trouble. There may be problems with the controllability of the machine with a cold engine, exhaust, the fuel consumption may increase or deteriorate the composition of the gases.
Note. Often the sensor changes only in cases when it breaks. But it is recommended to change it in advance, for example, when repairing or replacing the engine, because the sensor can wear out, and the readings may be inaccurate.
Dzhtoh, as the temperature sensor of the coolant is still briefly called the temperature sensor, the readings of which affect the operation of the engine itself. You should not forget about it.
Small, and a remote device closely monitors the engine engine systems, being a kind of watchman.
Replacement process
To check and replace the temperature instrument, the following tools and materials will be required:
- Caid key to "19";
- Sealant;
- Coolant;
- Copper washer.
Note. The temperature sensor is located in the VAZ 2110, often in the intake manifold near the thermostat case, rarely in the cylinder head.
It is installed so that the tip comes into contact with the coolant. Only in such cases its signal is correct.
If the coolant level is low, the sensor readings may be incorrect.
When you need a replacement
With a high resistance of the sensor on a cold engine and not passing the electric current through a pointer, its arrow is located at a low value. In cases where the temperature pointer, the engine temperature is not specified, then, first of all, you need to check the electrical chains of the sensor.
You should also check the current supply to the electrical panel. With random jerking of the arrow of the pointer, an inaccurate supply of voltage or reception of non-stabilized voltage is possible.
This requires replacing the stabilizer.
If there are still suspicion of a malfunction of the temperature pointer, then before performing the replacement, it should be checked its performance:
- in the event that the arrow indicates low temperature motor, then you need to disconnect the electrical connector from the temperature sensor and connect it with the mass;
- if when the ignition is turned on, the arrow deflects that, faulty, and it must be changed;
- if you do not move the arrow, you need to remove the instrument combination and check the electrical circuit between the pointer and the sensor and the supply of the voltage (the serviceability of the electrical circuit means that the temperature pointer is defective and it must be replaced).
Note. It should be borne in mind that quite often problems with the device arise due to poor wiring or loose rusty connectors.
- in cases where the temperature pointer constantly shows a high temperature, then you need to disconnect an electrical connector from the device (if the index arrow is moved when the ignition is turned on on the cold temperature scale, this indicates a malfunction of the temperature sensor and need to be changed).
A breakdown of this device is sometimes noticeable visually - this is a leakage of liquid, strong corrosion of clamps or cracks on it.
Note. You should also check the condition and coolant. If it was used for more than 3 years (for usual) and more than 5 years (for durable), then it must be replaced. It is replaced with explicit signs of its pollution.
Replacement directly
The replacement of the DPE is performed in the following order:
- First turns off the ignition and from the terminal rechargeable battery the wire is disconnected;
- Merges from the radiator coolant;
Note. The cooling fluid is not necessary to drain completely, you can open the shore valve and drain this volume of the fluid so that its level is below the sensor.
- To work comfortably, you can remove the air filter;
- The shoe with wires is disconnected from the temperature sensor with the pressing of the plastic clamp;
- Duzov is turned out of the cooling system nozzle using a key to "19" (while the sensor is removed along with the copper sealing washer).
Note. Working with the sensor, it is necessary to abide care.
Due to the damage to the device, the normal operation of the engine control system may violate. You need to know that it cannot be removed until the engine cools.
If you need to replace a new sensor installed in the reverse order.
- Before screwing the temperature sensor, a thin layer of sealant is applied on its thread;
- The sensor is then screwed into place and the electrical connector is connected to it;
- The cooling system is poured or coolant;
- After that, the engine is launched and the temperature indicator sensor operation is checked.
In conclusion, the cooling system is checked for leaks. If there is a need, the sensor turns stronger in the thermostat body.
It is also necessary to check the cooling system for the presence of air in it, which, falling into the thermostat, can cause engine overheating by changing the temperature sensor readings.
Note. In cases where it fails to flow, it is necessary to reinstall the sensor. It will be necessary to apply to the threaded part more heat-resistant sealant or replace the copper washer.
It is recommended to see this video before working.
In addition, it is advised to use more often with photo materials, where everything is clearly visible.
With your own hands, as it becomes seen from the article, you can make a lot, including and repair your car. If you do everything, as the instruction requires, then there will be no problems, even the newcomer will not arise.
In addition, you can safely save a family budget, because the price of the services of this type in our country is not cheap.
It's no secret that today's cars have a huge number of different electrical appliances. VAZ 2114 is no exception to the rules. Despite the fact that this brand of cars domestic productionIt also has various electrical appliances that require attention. For example, you can often hear from the owners of this car, that the car in the summer has the property to overheat. That this does not happen and there is a Cooling fluid temperature sensor 2114. As a rule, it is it that leads the car owners of VAZ 2114.
What is the temperature of the temperature mode and the fault is threatened
Many drivers know that overheating of the machine is able to disrupt the functionality of the entire power unit. The main purpose of this sensor is the stable support for a specific temperature for the machine. If someone does not know, the temperature regime must meet the established standards otherwise the car simply breaks and have to pay a lot of money to restore the operation of the engine.
If the temperature sensor works properly, then when the car is overheating, it must automatically turn on to the operating mode. As a rule, information about the state of the car comes directly to the electric motor.
Main sensor functions:
- makes control of all the work of the car;
- reveals in a timely a variety of breakdowns;
- does not allow the car in the summer period of time;
- controls changes in fuel parameters;
- controls the rotation of the crankshaft.
Where the sensor is located
In the machines with an injector there are 2 full-fledged sensors. The first is called to forward information directly to the ECU, which in turn decides how much you need to send to the fuel motor. The second sensor is applied solely to turn on and off cooling. In addition, with an arrow or other pointer, the sensor sends data to the car owner on the temperature state.
How much will the replacement of the cooling sensor per hundred
Replacing the cooling fluid temperature sensor VAZ 2114 Car owner will not have much from 1500 to 2000 thousand rubles. And this money will have to pay only for the work directly, and still need to understand that some details will have to buy. Therefore, experienced car owners recommend replacing the cooling sensor on their own. The procedure is simple, almost every car enthusiast, having at least some small idea of \u200b\u200bthe VAZ 2114 can do it independently.
Detailed instructions for replacing the sensor - in this video:
Below we will present another solution to this problem.
Symptoms for which you can define a breakdown of your sensor
The easiest way to break the sensor can be determined by carburetor engine: the temperature indicator immediately changes immediately. The more heats up force aggregateMoreover, the resistance of the sensor will be one of the common signs of the cooling system malfunction.
Overheating of the motor can occur for several reasons:
- overhaul high temperature on the street;
- cooling sensor contamination;
- failure in the functioning of the ventilation system responsible for cooling the engine;
- thread antifreeze;
- the thermostat was broken;
- malfunction in pumping;
- excessive gasoline consumption.
How to independently check the sensor
Most people will say that an absolutely crazy idea, since the fair value of the sensor provides the likelihood of buying a new unit. But this fact does not stop this fact because of savings or desire to learn something new. The sensor check is needed primarily in order to install the root cause, which led to the engine overheating.
To check this item, you need to make such actions:
- Drain completely antifreeze.
- Implement the sensor.
Dismantling
In its structure, the device of a small diameter in the form of a threaded sleeve is screwed into the collector. The center of this element is the thermal sensor, which monitors the change in the temperature regime.
If the device is inoperable, the sensor parsing is unreasonable. It is easier to throw it and buy a new one.
If there are doubts about the fault of the device, you can check it using a thermometer. The resistance of the sensor in the cold state should roughly be approximately 1500 ohms. With a gradual heating, the testimony should change. At the temperature mode of heating at seventy degrees, the resistance should be about 300 ohms, and with direct boiling - no more ninety. Only so you can confirm the operation of the device.
If you came to the opinion that the device is easier to buy, then when it is installed on the VAZ 2114 you need to use the key 21. In order for the sensor firmly fixed in its place, you need a small amount of sealant on the thread. Also, do not forget to pour the cooling fluid into the motor cylinder itself and into the radiator.
How to change the coolant temperature sensor with its hands
If you do not want to spend money on repair, we will tell you how to change the cooling fluid temperature sensor yourself. Follow the instructions below and then you quickly decide the problem.
Outcome
If a fault, the temperature sensor is better replaced immediately. As you can see, it can be done independently, but if you do not want to spend your time, contact a hundred. In any case, the situation is better not to delay.
