How to find out the engine temperature of a Lada Granta 2012

Lada Granta displays temperature data on the instrument panel

As you know, AVTOVAZ removed the internal combustion engine temperature scale from the panel on the new Grants and Kalinas and left only the overheating light, but if it lights up, then this is already the beginning of the end.
Therefore, in luxury trim levels, the coolant temperature display was added to the on-board computer readings, and for all others, only a collective farm is assumed in the form of installing additional screens in place of button covers or external On-board computers. To fix this problem, you can update the dashboard firmware of Lada Granta and Kalina 2 cars.

First, we find out what version of the firmware is embedded in the instrument panel.

Now let's decipher them

The first numbers (2190 or 2192) indicate the car model (Granta or Kalina 2). This is followed by the numbers 00, 20 or 40, which stand for “standard”, “norm” or “lux”, respectively.

Now, using the table below, you can see if it is possible to flash your panel so that it displays the temperature.

FIRMWARE VERSIONS OF INSTRUMENT PANELS LADA GRANT AND KALINA 2

Here is an example of firmware for the Grants Norma panel. Initially, the panel is sewn with firmware 090

We take out the panel, remove the back cover, and connect the programmer to a special connector on the panel board.

We upload the new firmware and go try it in the car. As you can see, the version has been updated and now firmware 092 is installed

And using the buttons on the right switch we switch the on-board computer readings and see that the temperature display has appeared.

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.

Solution from Maxim103

The car is September or August 2013, the equipment is the very first norm for casting (Izhevsk assembly), if the firmware costs 90, the sensor should be determined. How to check the firmware number: hold down the daily mileage reset button, turn on the ignition, all the lights on the panel should light up and the arrows should start moving up and down, release the mileage button, then press it again, the screen will display several lines with numbers, as far as I remember the version The top firmware looks like 090. Now, as far as I know, new firmware has been installed on all cars since the summer.

Or buy an on-board computer with this function

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.

Installing a separate engine temperature indicator

A similar engine temperature indicator is installed in any free hole in the car interior. The installation procedure itself does not take much time.

Attention! First you need to turn off all power in the car. It is best to remove the terminals from the battery.

Now you can begin the procedure:

Now you can turn on the power to the car using the battery and start the car. The engine temperature indicator should turn on and indicate a combination of numbers indicating degrees Celsius.

View the temperature using a smartphone or tablet

On modern Lada Granta or Kalina, you can view the temperature using a smartphone or tablet. Only to perform this procedure, the car owner will need to buy a special cable.

This cable works via Bluetooth. You will also need to download a special program to your phone with the Android operating system. Using it, it will be possible to view the engine heating degrees.

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.

The Lada Granta car is equipped with two instrument clusters. Let's call the first instrument cluster the old one; it does not have a temperature indicator, but only a warning lamp for engine overheating. Another model of the instrument cluster already shows the engine temperature, but only in the on-board computer.

How to fix the missing engine temperature indicators in Lada Granta and Kalina-2?

Not everything that our designers adopt from imported cars is useful for the consumer. So all cars used to have a dial indicator for engine temperature, but then VAZ engineers decided that the very fact of its presence meant that the cooling system was not reliable enough.

Also in this issue

Obviously stupid, and it was later corrected. On the panel displays of the latest releases, a digital indication of a previously rejected control parameter has appeared. But it is recommended to do the same on previously released machines. In the article we will find out how.

Why control the temperature

The more experienced the driver, the more the slightest deviations in the temperature of the antifreeze in the engine can tell him. No matter what trouble-free and powerful cooling system it has. And leaving the driver with only an overtemperature indicator light is not the best solution. Even the excess may be different and have a different background.

Different solutions

Technically there are no special problems. A temperature sensor is installed on the cars; it is necessary for the operation of the fuel injection system; all its readings are constantly read by the engine management system, digitized and stored in memory. All that remains is to extract them from there and display them on a convenient indicator.

Working temperature sensor / Source: Drom

If the owner is lucky, then he will already have a new type of instrument cluster on his car, in which it is enough to just change the factory firmware - and the data will appear on the place of the LCD display provided for them. You just need to study the issue or contact service station specialists.

Earlier panels cannot be easily re-skinned; the display matrix will have to be resoldered. This operation is unlikely to be justified; there is an easier way.

There is a plug on the center console of these Lada cars, by removing which you can put in its place a specially made and commercially available temperature indicator with large, contrasting, easily readable numbers.

The indicator itself will find the necessary information in the ECM memory and display it for the driver; you just need to connect it to the wiring of the on-board diagnostic connector in accordance with the attached instructions. This will not harm the connector itself in any way.

Grant engine temperature sensor. We install it ourselves

Every owner of a Lada Granta car has encountered its main drawback - the absence of an engine temperature sensor on the panel. The task of the AvtoVAZ management was to make Grant accessible, the engineers did it “excellently”, saving even on this device. The emphasis was on cheapness, so we tried.

Soon, however, everything was corrected - on models of a higher price and advanced configuration of the Lada Granta liftback 21911, 21912, 21917, an engine temperature sensor has already appeared and helps monitor the condition of the internal combustion engine. However, what should owners of earlier models do? The overheating indicator lamp installed on cars is not informative enough. In winter, it is impossible to determine whether the engine is warm enough to start driving, and in summer, the overheating warning light may come on too late.

The thermostat is the weak point of Lada Granta cars, and it would be much more effective to determine its malfunction at a very early stage by assessing the behavior of the TD sensor needle, but...

It was these problems that prompted some motorists to look for answers to the question: “How to install an engine temperature sensor on a Grant?” You can, of course, contact dealers. For a fee, specialists will equip everything you need. But there's no need to rush. It is not at all difficult to equip your car with this device yourself. To make sure of this, let's look at the whole process step by step.

How to equip your Grant with an engine temperature sensor

First, you should purchase an installation kit for the coolant temperature sensor (engine). If you don’t want to go to a car store far, or don’t want to, you can easily order the necessary kit in an online store with home delivery. It includes:

1. temperature indicator,
2. plastic case for it,
3. the sensor itself;
4. fastening clamps.

Once you have the kit in your hands, it's time to head to the car. To see the place where the Grant engine temperature sensor will be attached, the negative terminal is removed from the car battery, and behind it the air filter is disconnected and removed.

This will open an overview of the pipe that leads from the thermostat. Coolant circulates through it during operation.

It is necessary to carefully cut the pipe and insert the temperature sensor inside along with the adapter (buy at a car store), then securely tighten it with clamps.

Knock sensor Lada Granta

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 on the Grant, 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. The knock sensor on the Lada Granta is located directly on the cylinder block (more precisely, between the second and third cylinders).

Operating a vehicle may lead to malfunctions, for example, the engine may lose power. This symptom indicates that there are obvious problems with the knock sensor. The presence of a malfunction is indicated by the illuminated “Check Engine” lamp, and diagnostics almost always reveal one of the following errors:

Sensors on the Lada Granta engine

To ensure the normal operation of all vehicle components, modern cars use many different regulators. In this article we will talk in more detail about domestic Lada cars. Where is the speed sensor, coolant and other controllers on the Lada Granta and what functions do they perform - read below.

Sensor locations

Where is and how to find this or that regulator on Grant, Priora, Vesta or Largus? In fact, the location of the devices on these car models is identical. Below is a diagram identifying all devices.

Characteristics of sensors

Speeds

The Lada Granta speed sensor is located on the gearbox housing. This regulator is directly related to the transmission of data about how fast the vehicle is moving, how the car is idling, and what kind of gas mileage it is driving at.

To find this controller on a Priora or Grant, you need to open the hood and remove the air supply hose that goes from the air filter element to the throttle. Having done this, at the bottom of the gearbox housing you can see the controller with a wire connected to it. To replace the device, you simply need to disconnect the wiring and remove it from the installation location, and then replace it with a new one.

Removing DTOZH from a car

A coolant temperature sensor is necessary to measure the temperature of antifreeze in the cooling system. In accordance with the data from the temperature regulator on the Grant, the control unit adjusts the crankshaft speed, adjusts the composition of the combustible mixture, as well as the ignition timing.

As practice shows, such a device rarely fails, but in some cases it can give incorrect readings. Located in the engine compartment, in particular, in the thermostat cover, the controller has its own “diseases”. The wiring at the base of the connector may fray, resulting in the need to replace the DTOZH.

The mass air flow controller is located behind the air filter element of the power unit, it is also often called a flow meter.

The main purpose of the device is to monitor the volume of air flow that enters the vehicle engine.

In accordance with the data received, the on-board computer determines the required volume of gasoline, which is necessary to maintain a normal air-fuel ratio.

The idle speed sensor is one of the regulators designed to monitor and control the operation of the power unit. If the device breaks down, the motor immediately begins to work incorrectly - it will trip and the power will decrease.

In turn, the needle on the tachometer will jump sharply from one value to another. The element itself is located on the throttle, in particular on its lower part.

To get to it, you need to free the throttle valve from the pipes, there are four in total.

To replace and install a new IAC, you will need to disconnect the wiring from the regulator itself, as well as the throttle position controller.

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.

Clutches and brakes

The clutch sensor allows you to determine the position of the pedal. When the pedal is not depressed, the regulator turns off the load adjustment on the power unit. The device is located in the pedal assembly, in the same place where the brake sensor is located.

The operating principle of the latter is quite simple:

• when the pedal is released, the rod is located inside and clamps the floating contact to the top;
• when the pedal is depressed, the rod clamps the contact to the bottom of the group.

As practice shows, one of the main problems of this controller is the poor quality of the contact itself. It can simply catch on the spring, and ultimately the control unit will receive an impulse to apply the brake.

The vast majority of modern cars, including the Lada Granta, are equipped with digital sensors. “Scanners” transmit readings online to the electronic control unit of the ECU.

The on-board computer compares the received data with the programmed ones. In case of discrepancy, an error is indicated on the dashboard. The owner of the car, seeing a system error, decides on the nature of the breakdown and visits a service station to order a comprehensive diagnosis.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

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

In total, over ten digital and mechanical sensors are installed in the Lada Granta. The following deserve special attention and control from the driver:

• Coolant temperature sensor (hereinafter referred to as DTOZH);
• Environmental DT (hereinafter referred to as DTOS).

The functionality of the devices and the accuracy of data display depend on the condition of the technical equipment and the safety of driving a car.

DTOZH is designed to monitor the temperature of antifreeze in the cooling system circuit of the power unit. After receiving data about the “degree” of the engine, the ECU increases or decreases the speed of the power unit in order to adjust the temperature.

The quality composition of the fuel mixture depends on the accuracy of the DTOZ readings. The service life of the sensor is unlimited, with the exception of mechanical damage or manufacturing defects.

The standard installation location is the thermostat cover. The base part is screwed into the thermostat housing. Two power supply cables extend from the top.

A melting element is installed inside the DTOZh base. As soon as the antifreeze temperature reaches 90, the contacts close and the on-board computer signals an error.

Catalog articles, prices of temperature sensors for Lada Granta

Installed at the front bumper mounting location, to the left of the central air duct. The DTOS shape is conical with two contacts on the back side.

The fuse in the mounting block at number 32 is responsible for the operation of the DTOS. The first sign of a malfunction is the absence of temperature readings on the dashboard.

Is it possible to become infected with coronavirus without fever?

Fever is one of the main symptoms of Covid-19 (Image: Getty Images) As coronavirus has impacted every aspect of our lives in recent months, many of us will also be looking for any signs or symptoms that may indicate a case of Covid-19.

And while they can vary greatly, the most common one is fever, which is defined as a hot sensation when touched on the chest or back.

But with coronavirus cases varying in both symptoms and severity, is it possible to catch the virus and not have a fever?

Here's what you need to know...

Is it possible to get coronavirus without fever?

Fever is listed as the most common symptom of Covid-19, along with a new, persistent cough and loss of taste or smell, according to the NHS.

Absolute pressure and air temperature sensors Lada Granta

These sensors are combined into one housing and installed on the receivers of the intake module; the most modern AvtoVAZ engines are equipped with them.

DBP on Grant differs in the output signal voltage within the range of 0.15..4.6 V, this voltage depends on the pressure level inside the intake pipe. The information it sends helps the ECU calculate the amount of air received by the intake pipe during one cycle.

A breakdown of the device circuit leads to an error code being entered into the system memory, and then the alarm turns on. After this, the control system calculates the air received based on the crankshaft speed, as well as based on the throttle valve opening angle.

The sensitive component of the DTV is the inlet pipe thermistor. The output signal voltage of the device connected to the computer will be approximately 0.3..4.9 V, it depends on the temperature of the air passing through the specified element. When a DTV failure is detected, the control system performs actions similar to its actions in the event of a DBP failure on a Lada Granta, replacing the readings of the described device with fixed temperature values.

Removing the coolant sensor Lada Granta

The Lada Granta coolant temperature sensor is a thermistor (a resistor whose resistance changes depending on the temperature). The sensor is screwed into the thermostat housing and connected to the controller input, connected to an internal voltage source of 5 V through a 2 kOhm resistor. At low temperatures, the resistance of the sensor is high, and at high temperatures it is low (Table 1). The controller calculates the coolant temperature from the voltage drop on the sensor. On a cold engine the voltage drop is high, and on a warm engine it is low. Coolant temperature affects most of the characteristics controlled by the controller.

To remove the sensor you will need: a 19mm wrench and a multimeter.

If you have a 21126 engine, then you can see the algorithm for removing the sensor in the article “Replacing the coolant temperature indicator sensor in Lada Priora”

If you have an 8 valve engine, use the guide below.

1. Disconnect the wire from the negative terminal of the battery.2. Partially drain the coolant from the radiator.3. For ease of operation, remove the air filter (see “Removing and installing the air filter, air supply hose and air intake of the Lada Granta”).4. Press the clamp of the wiring harness block...

5. ...and disconnect the block from the sensor.

6. Unscrew the sensor from the thermostat housing.

7. Remove the sensor.

Check the sensor in ohmmeter mode, connect probes to the sensor terminals and measure its resistance. Measure the current air temperature with a thermometer and compare the obtained values ​​with the data in the table. 1. If the resistance deviates from the norm, replace the sensor.

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.

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:

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

The replacement procedure is carried out as follows:

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.

Installing an outside temperature sensor on a Lada Granta

The outside air temperature sensor, despite its apparent simplicity and low usefulness, is actually quite an important element of driving safety. In spring or autumn, when the roads are often filled with melt water, driving a car at zero temperatures is especially dangerous.

From the driver's seat, the asphalt may appear dry or simply damp, when in fact the asphalt is coated with a glaze of ice.

The outside air temperature sensor will help predict these events, because if it shows the temperature below zero and the roads are wet, then most likely the asphalt will be extremely slippery and you will need to choose a different driving style and increase the distance to the car in front.

However, in order to save money, AvtoVAZ does not equip its cars with an outside temperature sensor in the basic configurations of the Lada Granta and Lada Kalina, but the ability to install it yourself is present in a number of cars.

To check the possibility of installing an outside temperature sensor on your car, you will need to check the firmware version of the instrument cluster.

To do this, with the car turned off, press the daily mileage reset button on the instrument panel and turn on the ignition. The instrument panel will go into self-diagnosis mode.

Press the odometer button again once and you will see the instrument cluster firmware version.

If your version is 090 and higher, then the instrument cluster is available for installing an outside temperature sensor. All versions that have a serial number below 090 do not provide for the installation of the corresponding sensor.

If in your case the instrument cluster is available for installing an outside temperature sensor, purchase the required sensor DVT-2115-3828210-03 from a car store.

The manufacturer provides a standard mounting location for the temperature sensor; it is located in the lower part of the engine cooling radiator on the frame of the bulkhead amplifier. The mass for the sensor is taken in the same place, there is a corresponding nut nearby.

The installation location is clearly visible with the front bumper removed. We marked in red the installation location of the outside air temperature sensor, and in black the installation location of the sensor mass.

We will need to run the power wire into the car interior and connect it to the instrument panel. You can insert the wire into any available rubber plug on the front panel, for example, into the clutch cable plug.

Having removed the instrument panel, we connect the positive wire to the 25th leg of the instrument panel connector. The installation location is marked with an arrow.

If the work is carried out correctly and according to our instructions, then when reassembling and connecting the instrument panel, the on-board computer menu item will contain a corresponding item displaying the temperature outside the car.

If the temperature indications do not appear, unscrew the negative terminal from the car battery for 5-10 minutes to reset the settings of the instrument panel and electronic control unit, after such a procedure the temperature indications should appear.

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:

Speed ​​sensor

The DS is intended to measure the speed of a vehicle, with subsequent transmission of the received data to the ECU. The speed sensor is a small part; it is located in the upper part of the clutch housing, near the front wheel on the right. Its malfunction is usually directly related to a breakdown of the speedometer. However, the sensors installed on Grants are distinguished by fairly high quality and durability.

By the way, initially three types of speed sensors were installed on Grants: VAZ-2170 PEGAS, 2190 AVAR Russia and 21700-3843010-02.

More details about the speed sensor on Grants.

If the DS malfunctions, the electric power steering most often stops functioning, and at the same time the instrument panel begins to display error P-0501. As a rule, the steering wheel fails precisely because the car detects a breakdown of the speed sensor; the DS itself may show zero speed.

If the sensor fails, the following symptoms of failure are noted:

These parts have their own markings, their price ranges from 300 to 600 rubles.
