Grant temperature sensor: where is it located, check, repair of DT coolant on Lada

Why does coolant boil?

Sometimes you can see a car standing on the side of the road with the hood raised, from under which steam is pouring out. This is the result of a failure of the Lada Granta temperature sensor. The device provided incorrect information to the electronic control unit (ECU), and the ventilation system was unable to operate in time, which is why the antifreeze began to boil.

If the coolant temperature sensor (DTOZh) on the Lada Granta is faulty, the antifreeze may boil for several reasons:

1. Loose timing belt.
2. Destruction of the pump bearing.
3. Thermostat failure.
4. Antifreeze leak.

Loose timing belt

The belt tension may become weak due to the exhaustion of its running life or poor manufacturing quality. The belt begins to slide along the teeth of the pump drive gear. The speed of movement of antifreeze in the radiator drops, and the temperature sharply “flies” upward. The belt is tightened or replaced with a new product.

Timing belt:

Pump bearing failure

The consequence of a failure of the coolant pump bearing is that the pump begins to jam. Antifreeze stops moving inside the large cooling system circuit on the Grant, and the liquid, quickly heating up, reaches the boiling point of 100 ° C. The pump is urgently dismantled and replaced with a new pump.

Water pump:

Thermostat failure

Over time, the device may exhaust its resource, and the valve stops working when the antifreeze heats up. As a result, antifreeze cannot circulate in a large circuit and pass through the radiator. The liquid, remaining in the engine jacket, quickly heats up and boils. The thermostat needs urgent replacement.

Thermostat:

Antifreeze leak

This can happen due to leakage in the connections of the cooling system pipes, damage to the radiator, expansion tank and pump. A low antifreeze level can be seen by the marks on the expansion tank. This will also be noticeable by how quickly the needle moves or the temperature values ​​​​change on the instrument panel interface. You need to add fluid to the required level and go to the garage or service station.

New instrument panel

New instrument panel combination (from June 16, 2014)

If your car was manufactured after June 15, then the engine temperature should be displayed in the on-board computer. If it is not there, then you need to reflash the instrument panel.

We found ways to save money. And putting an additional indication is a collective farm!

Where to buy a button?

Which button? If on-board instead of a button, then in almost any auto store that specializes in domestic cars!

You are probably talking about STATE1? So, my experience shows that STAT1 never shows the temperature accurately, sometimes the error ranges up to 13 degrees in the direction of underestimation!

Let us remind you that on the website you can find out what the real fuel consumption of the Lada Grant and Lada Kalina 2 should be.

I installed the additional indicator at a car dealership for 2500 rubles, purchasing it on June 9, 2014. Eh, I would have purchased the shipment after June 15, if only I had a computer on board)

I installed the indicator in the cabin for 2500 rubles on June 9, 2014, a necessary thing

Damn you are needed)) they write the red price is 600. ) And why are you lost) stop by and see the guys, they will stick you a flatbed for 35) I think they won’t refuse such a necessary person!)

Soon you will probably have to buy seats separately, like mats, armor. On the 14th, everything was there, engine temperature, ambient air temperature, battery charging. I bought a Lada Granta, there is nothing.

The same bullshit generally blew my mind at first, also after 14 - oh, on a grant, I moved to an empty one, there wasn’t even a puff filter, damn economists...

Where can I buy such a sensor in Moscow? I can not find

I have a grant for 13 years. I reflashed the computer a couple of times. There is no trust in him. The check lights up and displays errors for items that are not in the car. Naturally, there is no temperature sensor either. What were you thinking? Don't know. The fan is electronic and needs monitoring. And you don’t know whether it works or not. Russia in a word. We hope so. And it is not known whether the overheat sensor will work or not. It didn't seem to catch fire yet. And if it ever lights up, in any case it is not good, this is already the limit, although the cause could have been established earlier if there was a temperature sensor. Thank God I have to change the car in a year, maybe by then there will be something new.

My friend, those who have their hands full are always taken on a tow truck. And what’s interesting is that they gave birth to more than enough of them “waist-deep.” I have seen almost every brand with an infinite number of car models being taken to a tow truck for repairs. And these were not “Muscovites” - these were only after an accident. Now the girls’ heels will start clicking that Moskvich is not a machine. And don’t give a fuck about buying a car with which you, the generation that chooses PEPSI, fuck with tears in your eyes, whining and vilifying the auto industry of the country that is, in fact, your Homeland. The thing is that rear-wheel drive owners of modern junk cars worth several hundred thousand Pindosyat money don’t particularly worry about the breakdowns of their cars and don’t shed tears on various kinds of forums the way the rest of the herd does, who own quite durable cars that didn’t go to the owners. those who want to comprehend the interesting world called a CAR WITH INTERNAL COMBUSTION ENGINE, not even because of their laziness, although this is present, but because of innate or acquired dullness, inability to perceive information, with its subsequent processing and execution in the form of repairing their car with their own hands. Opening a can of beer with these hands is a completely different matter. Since childhood we have seen enough of this goodness on TV. Unable to carry out repairs yourself, you give the car to the same complete mechanics from the service center where your housemates or street neighbors work and try to do the repairs for minimal money. And the repairman, seeing the client’s tight-fistedness and the condition of the car he needs to fuck with, because... the car has not seen proper care for a very long time, and is trying, in turn, to screw over cunning clients, realizing that there is no money to be made here, because... the whole condition is crap and cannot be unscrewed, rotten, worn out.

Recommendations for care and maintenance of sensors

• Strictly follow the manufacturer's recommendations regarding vehicle maintenance schedules;
• Preferably buy parts with original catalog numbers. The exact data is indicated in the instruction manual for your technical device;
• Carry out preventive maintenance, install consumables and spare parts in certified service stations. This is especially true when the car is under factory warranty. There are frequent cases of warranty cancellation due to third-party intervention.
• When the first signs of engine malfunction appear, contact a service station.

Purpose

The process of ignition of the fuel mixture in the cylinders of the internal combustion engine is accompanied by an increase in temperature to 20000C. If you do not maintain operating temperature conditions, the cylinder block with all its parts will simply collapse. The purpose of the engine cooling system is precisely to maintain the thermal operating conditions of the engine at a safe level.

The Grant engine temperature sensor is a meter that tells the ECU about the degree of heating of the antifreeze. The electronic unit, in turn, analyzing data from all sensors, including DTOZH, brings all internal combustion engine systems to a balanced optimal operating mode.

DTOZH:

Displaying temperature data on the instrument panel

AvtoVAZ manufacturers answered the question of experienced mechanics: why there are no heating degrees on the instrument panels of vehicles from the Russian manufacturer. They claim that this was done because it was unnecessary to display these numbers. Because the engine is configured in such a way that the temperature in it is always maintained at an optimal temperature. There were no cases of overheating.

Attention! AvtoVAZ manufacturers allow car owners not to warm up the car. They refer to European environmental standards. Allegedly, by not warming up the engine, the car owner does not destroy nature and saves fuel.

However, experienced mechanics and car owners managed to display information on the dashboard screen. Some even buy special devices to determine engine temperature.

Now we’ll find out how to check the engine temperature on a Lada Granta car.

On ordinary Russian-made cars, although there is no engine temperature scale, in top trim levels, or as they are also called “Lux”, this scale remains. It is called the coolant or antifreeze temperature scale.

On other machines, only places for installing additional devices for determining this data are provided. Now, you need to find out whether the ECU firmware will show the temperature if the car owner installs additional devices.

1. Turn off the ignition.
2. Press the daily mileage reset button and turn the ignition key to the “Start” position.
3. Now notice that all the indicators turn on and the arrows on the panel move. This means that the system has entered service mode.
4. You need to release the reset key.
5. Press it again.
6. The numbers that appear on the scale indicate the firmware version.

Let's see if we can flash the equipment so that it shows the engine temperature.

For Grant Standard:

• 015 – not possible due to the old modification of the motherboard;
• 029 – 040 – not possible due to the old modification of the board;
• 053, 060, 076, 087 - you will have to work with a soldering tool. Experienced mechanics reflash the device to the new 2190-20 092 For 076.

For Grant Norm:

• 090, 091 – it is allowed to change the air heating sensor on the street, you cannot install DTOZH;
• 092-095 – it is allowed to change the air heating sensor, you can also change the TOZh sensor;
• 032, 038, 042 – it is possible to change the outside air heating sensor, you cannot install DTOZH.

For Grant Lux:

• 046 – allowed;
• 047 – allowed;
• 007 – it is allowed to replace the system with 046.

For Kalina Norma:

For Kalina Lux:

Now you will need to flash the ECU with a new program. They do this as follows:

1. Pull out the panel and connect the programmer device to it.
2. Upload new firmware.
3. Turn on the ignition and poke the buttons with your finger, watching how the icons switch on the screen.
4. Switch until the screen displays the motor temperature.

This completes the display of motor heating on the toolbar screen.

Design and principle of operation

The temperature meter on Grant is a thermal variable resistor. The thermocouple, enclosed in a bronze case with a threaded tip, reduces the resistance of the electrical circuit when heated. This allows the ECU to determine the coolant temperature.

DTOZH device:

If you look at the sensor in cross-section, you can see two contact petals located at the top and bottom of a thermistor made of a special metal alloy, which changes its resistance depending on the degree of heating. It closes both contacts. One is supplied with power from the on-board network. The current, having passed through a resistor with a changed characteristic, exits through the second contact and enters the ECU microprocessor through the wire.

The following parameters of internal combustion engine operation depend on the DTOZH:

• temperature indicator readings on the instrument panel;
• timely activation of the internal combustion engine forced cooling fan;
• enrichment of the fuel mixture;
• engine idle speed.

Mass air flow sensor

The mass air flow sensor is designed to count the air sucked into the engine to adjust the fuel mixture. The readings from the sensor are sent to the ECU. This sensor is one of the most expensive on Grant. It is installed on the air filter housing and secured with two 6mm bolts.

Symptoms of malfunction:

• High fuel consumption;
• Uneven engine operation;
• Floating XX;

Knock sensor

The main tasks of this element include the determination of high-frequency oscillations resulting from fuel combustion in the cylinder block.

Based on the DD signal, the control system selects the most suitable ignition timing angle, thanks to which efficient and complete combustion of fuel is achieved in the cylinder block of the car engine. In addition, the ignition timing is also regulated, which is important when using fuel with different octane numbers. This element is located directly on the cylinder block (more precisely, between the second and third cylinders).

What temperature sensors are installed on the Lada Granta, where are they located and the price

Now let's see what devices are installed on Russian cars and where they can be found.

• Lada Granta engine coolant temperature sensor is installed in the thermostat cover - 300 rubles;
• detonation device at the front of the cylinder block wall. Between the second and third;
• the device for determining the location of the crankshaft is found in a special opening in the tide of the oil pump cover;
• device for determining phases or camshaft - 2000 rubles;
• air and pressure measuring device;
• lambda probe - 1000 rubles;
• device for calculating mass air flow - 1800 rubles;
• device for determining speed - 310 rubles;
• oil pressure.

Prices are for used and new devices. You need to find out more about the cost in special auto stores.

Attention! Experienced mechanics do not recommend buying equipment on open markets. It is best to make purchases in specialized stores or service centers.

Catalog items

The serial number for the engine temperature gauge of a vehicle from a domestic manufacturer is 2190-94. It is not being repaired. Experienced mechanics advise checking this device before replacing it. At the service center, the procedure is carried out at special stands. But you can check it at home.

Self-replacement of the temperature sensor

The check is done as follows:

1. Immerse the device in hot water.
2. Then they measure the resistance.
3. The values ​​may vary on different devices. You need to read the manual and find out what the optimal resistance of the device is.

If it does not reach the specified values, then the sensor needs to be replaced.

The replacement procedure is carried out as follows:

1. Buy a thermostat. A kit is sold that includes an indicator, a housing for the indicator, a thermostat and fasteners.
2. Remove the air filter and disconnect the battery.
3. The car owner will see a pipe that goes to the thermostat. It must be cut off on both sides carefully.
4. Replace with a new one and tighten the hose clamps.

At this point, the process of changing the thermostat is considered complete. Now all that remains is to observe the engine temperature through the instrument panel. At any slightest hesitation, you must contact the service center. Since it is possible that a faulty thermostat could play a cruel joke on you and display the temperature incorrectly. And at this time the engine overheated enormously.

Temperature sensor T811 | Server room environment monitoring

Temperature sensors A (T811) are designed to measure indoor air temperature without the possibility of water entering the sensor housing. The sensors are made in the form of a board mounted on a plastic case with slots.

Thermal sensors (T811) are connected to NetPing 2 / PWR-220 v4 / SMS, NetPing 2 / PWR-220 v3 / ETH IP power distribution units (IP PDUs). Information on connecting temperature sensors (T811) is given in the “User Manual” documents of the corresponding NetPing IP PDUs to which they are connected. Information on setting up temperature sensors (T811) is given in the “Firmware Description” documents of the corresponding NetPing IP PDUs to which they are connected.

All server room temperature sensors are connected in parallel to each other to the same contacts. The sensor model is indicated on the body of each digital temperature sensor. Before using the air temperature sensor, you must set the temperature sensor address yourself. The temperature sensor address is set by removing the temperature sensor board from the case and installing mechanical switches (jumpers) in a certain place using a screwdriver included with the NetPing power distribution units, or manually:

Disadvantages of low engine operating temperature

An engine that does not reach its operating temperature operates in the wrong modes.

1. The most basic problem is increased fuel consumption (read how to reduce fuel consumption on a Lada Granta here).
2. There is also a risk of breakage.
3. Well, the car interior will not warm up so well.

Remedies

Only replacing the thermostat with a model with an opening temperature of at least 92 degrees will help. Grant farmers purchase a WAHLER 3091.92D thermostat. They poke the insides out of it and insert it into the old thermostat.

In order not to disassemble the original thermostat ahead of time, you can purchase a thermostat for the Lada Granta, and put the insides from a non-original replacement into it.

This is a native Luzar thermostat

Old dashboard

On vehicle models before 2014, it will not be possible to view the temperature on the dashboard in any case. And, if you pay attention only to the overheating light, then when it lights up, it may be too late to save the engine.

In this case, installing a special engine temperature indicator will help. However, you first need to understand what the on-board computer values ​​on the panel mean in order to understand the problem.

On-board computer values ​​on the panel

The manufacturer says that you can drive with an engine that is not warmed up. Although this is fraught with major overhauls not only for the engine, but also for the automatic transmission. If you warm up the engine, then in hot regions you may not understand when the engine warms up to 80 degrees, and the temperature jumps above the set point. And when the engine starts to boil, it will be too late to wave your hands.

So how do you know that the heating levels in the engine have reached their climax? In this case, experienced mechanics suggest installing a special engine temperature indicator.

Sveta

As for the light sensor, it is installed in the same housing with the rain regulator. Its purpose is to activate and deactivate lighting based on the current state.

For example, if it gets dark outside or you enter a garage or poorly lit tunnel, the device should automatically turn on the headlights along with the side lights.

The controller itself is not repairable, so if it fails, the only option is to replace it.

Testing the mass air flow sensor using a multimeter

If you do not have any auto diagnostic devices, you can use a regular household tester (preferably electronic). The fact is that when measuring the voltage at the signal output of the sensor, accuracy to hundredths of a volt is required. It is advisable to use a multimeter with low measurement error.

First, check the supply voltage in the wiring harness coming from the ECU module.

Important! Be sure to disconnect the negative terminal of the battery before connecting (disconnecting) the mass air flow sensor connector. This will prevent false OBD-II errors from being generated.

1. Turn on the car ignition (no need to start the engine).
2. We check the 12 V supply voltage at the connector (the contact number must be specified in the MAF connection diagram specifically for your LADA Granta model).
3. We check the supply voltage of the 5 V sensors (similarly, according to the contact diagram).
4. Disconnect the negative terminal again and connect the connector back.
5. Turn on the ignition, start the engine and check the voltage at the signal output from the mass air flow sensor (you can use a pin inserted into the back of the terminal block).

6. A voltage from 0.99 to 1.02 volts indicates that the sensor is working properly. From 1.03 to 1.05 - the mass air flow sensor will soon have to be changed. More than 1.05 volts or no voltage - the sensor is faulty.
