Coolant temperature sensor errors

DmitryCorsten Blog Error codes for on-board computers of the Samara-2 family VAZ 2113, VAZ 2114, VAZ 2115

With the introduction by a special commission of the European Union of the mandatory characteristics of Euro-2 and Euro-3 in vehicle electronics, the misfire (ignition) system became mandatory for use as a function when programming the ECU.
Methods for its diagnostics were also integrated into the “brains” of the on-board vehicle. With its help, to prevent unnecessary toxicity of unused fuel, a program was installed to turn off cylinders with deficiencies in the injection system. This occurs by blocking the fuel supply through the injector system. With the help of preventive blocking of this function, the release of unburned fuel into the environment is stopped, and the functionality of the rather expensive complex of catalyst parts is not affected. On vehicles equipped with a set of additional electrical devices included in Euro-3 and subsequent generations, a VAZ rough road sensor is added to the ignition system interval control complex.

This indicator is positioned as the only device in the vehicle electronics that does not directly influence the management function of the Priora from the electrical on-board complex. When the question is posed this way, Russian car owners often ask why a rough road sensor is needed in a car.

Such a device has the function of protection when moving along sections of the roadway with obvious unevenness (bumps, ruts, etc.). Based on the pulses emitted by the device, the controller can temporarily stop the process of identifying intervals and turning off idle cylinders.

The standard device is located in the power compartment on the wing mudguard on the right side. Usually, it is mounted on a special protrusion and connected to the side panel via a three-pin contact. Finding a rough road sensor and replacing it is not particularly difficult.

Lada KalinaDND rough road sensor malfunction

the engine starts and stalls, elimination of error codes P1606/P1616/P1617, description of the cause of the error and its elimination.

It operates on the basis of the introduction of the piezoelectric effect by analogy with the knock sensor of the power plant, i.e., the acceleration signals that arise in the system when driving on an uneven road surface are transformed. Such a pulse is converted into a constant current voltage value, which is in direct proportion to the previous signal. This is how the controller identifies the position when the vehicle is moving along a road with difficult terrain and gives a command to disable the function of stopping the ignition of a flammable mixture.

When moving on a road surface with unevenness and potholes, the variable load effect of a variable type significantly affects the angular speed of rotation of the crankshaft of the technical device. Frequency pulses transmitted during rotation of the crankshaft of a technical device act as an analog signal, which appear during intervals of ignition of the air-fuel mixture.

The electrical rough road sensor in Priora measures the amount of vibration of the vehicle body and transmits the acquired impulse to the controller. If the permissible level of impulse characteristics is exceeded, the controlling sensor disables the characteristics of the combustion intervals of the injection system.

Replacement

Installing a new sensor is not a difficult job. To carry it out you will need a minimum of tools, as well as a little time:

Thus, work to replace the sensor is carried out on Lada Kalina and Lada Priora. On machines of other brands and models, this work may be performed differently.

Manufacturers

. If you have a foreign car, then it is better to purchase an original sensor from official suppliers. Even the most expensive models will cost relatively little. You shouldn’t save money and buy a Chinese “pig in a poke”; no one will guarantee the service life of the part.

Several of our companies produce DND for domestic production. The most famous are Kaluga sensors and those produced in Zelenograd. Connoisseurs of German quality can purchase a device manufactured by BOSCH.

Replacing the device

Technical properties of the sensor:

Checking the ADC pulse of the VAZ rough road sensor can be carried out using the DST-2M device or its analogues. The BSMW indicator is analyzed and diagnosed in the form of acceleration configuration g. If the sensor is subjected to a slight impact with a click or knock, then there is a change in acceleration values ​​with a different spectrum, from instantaneous to small values. In principle, this device is very sensitive, changes are observed even by the body's rocking.

To dismantle the Priora rough road sensor you will need a Phillips head screwdriver:

Table with errors

A complete list of faults with explanations and recommendations for troubleshooting:

Engine malfunctions

Possible causes of the problem:

• regular use of low-quality fuel;
• violation of air intake tightness;
• lack of spark;
• damage or physical wear of cylindrical devices.

If replacing the fuel does not help, it is necessary to diagnose the air intake system. You should tighten the fastening clamps, change the air filter element and check the pressure in the rail (the normalized value is no more than 2.8 atm).

It is also necessary to perform diagnostics:

• high-voltage wires connected to the defective cylinder;
• spark plugs;
• check for possible oxidation at the cable connection points.

Diagnostics of high-voltage wires is carried out using a tester; it is necessary to check the resistance. If the obtained value is more than 10 kOhm, then the cables must be replaced. You also need to check the integrity of the spark plugs and make sure there is no carbon deposits on their tips.

Possible causes of the problem:

• breakdown of the mass air flow sensor;
• lean or enriched air-fuel mixture in the engine cylinders;
• malfunction of the electronic engine control system unit.

To fix the problem, you can try to relearn the throttle valve, to do this, perform the following steps:

Possible solutions to the problem:

Electrical faults

When this combination appears, the following problems are possible:

Possible signs of problems:

• the car engine does not start or stalls for no reason;
• fuel consumption increased;
• electronic devices and mechanisms do not work correctly;
• the power of the power unit is lost, etc.

If you do not have the appropriate equipment and skills, you can follow these steps to resolve:

Indications for self-diagnosis and contacting specialized service stations will be different, error codes are also displayed differently. Therefore, today we will consider two options.

It is not at all necessary to use the on-board computer to diagnose problems with the car. Not all VAZ 2114 owners know about this method, so we will definitely tell you about it.

It consists of the following steps.

1. Sit in the driver's seat and hold down the odometer button.
2. Then turn the ignition key to the first position.
3. Release the odometer button. After this, the arrows will start moving.
4. Press the button again and turn it off. This will allow you to see which firmware version is used in your case.
5. Press and release the button a third time. So you will see codes indicating the presence of certain errors in the operation of the car.

Let's now look at the most popular errors that occur during such diagnostics and figure out what the code means. Even without an on-board computer, you can detect faults on the VAZ 2114 using the odometer codes.

We suggest you familiarize yourself with them in the table.

• VAZ repair.
  Check all sensors! Plus, all fault codes will be stored in memory until you manually reset them. To do this, you need to disconnect the terminals from the battery while keeping the ignition on, wait a few seconds and connect it back. Don’t forget to do this, especially if you are going to go to a service station for diagnostics. They will find these errors and will eliminate them, although in fact you have already done everything yourself before. Pay extra money? No, it's not worth it.

Errors in the idle system and ecu of the Lada Priora

P0500 - a malfunction in the sensor that is responsible for speed. When the last digit is 6, the speed is low, and when 7 is high. At 11 the regulator is broken, and at 60 the voltage is low, and at code 62 it is too low. Code 63 numbers indicate high voltage. 0601 - checksum malfunction. Code 0627 indicates tears in the fuel pump cables. With code 0645, 46 and 47 - problems with the air conditioner.

This is the main list of problems and malfunctions that occur in the car. If you decipher them correctly, then it will be much easier to repair the car and correct Priora errors. But even with the most effective equipment, you need to remember that a good auto mechanic cannot be replaced by any testing device.

Error P0123 - what it means, symptoms, causes, diagnosis, solution

Trouble code P0123 indicates a problem with the throttle/pedal position sensor. When the engine control module (ECM) detects that the rated output voltage of the throttle position sensor exceeds the manufacturer's specification, it generates trouble code P0123.

The throttle position sensor (TPS) is another name for a potentiometer. It is located on the throttle body while the pedal position sensor is connected to the accelerator pedal.

The throttle position sensor monitors the movement of the accelerator pedal and determines how much power the engine requires. Code P0123 is triggered when the TPS voltage value is outside the specified range.

The process of diagnosing a car using a tester or a connected computer

Much more accurate and reliable data when checking a car for malfunctions can be obtained if you use separately connected equipment. But the introduction of such tools and devices gives encrypted readings, therefore, in order to correctly understand and find all the faults in the car, you need to decrypt the data received from diagnostic devices. Of course, manufacturers could have done things easier for Russian-speaking car enthusiasts. It would be possible to write “replace the canister valve” on the device screen after diagnostics, but instead, only a code in the form of p0441 can be found on the display, and code p0130 will appear only due to problems with the oxygen sensor.

But the problem is that Lada Priora is produced not only for the domestic market, it is also produced for sale in other countries. Therefore, such a classification of automobile problems and their code on the testing device was created.

It is easier to enter only a certain number of universal codes into the program than to enter your own language data for each national market. As a result, you can look at a specific code on the display and easily determine the essence of the problem in the car using a list that lists all encrypted codes. A special code is used to indicate error codes on the Lada Priora car. This cipher includes:

On the Lada Priora, all gap codes in the vehicle's operation will have five digits. Here is a complete list of Priora designations. The first character of the code will be a Latin letter. The letter “P” indicates problems with the engine, or more precisely with its electronic system. The letter “B” indicates problems with the interior electronics.

The letter “C” is present on the screen only if there are failures in the electronic system of the vehicle chassis. If combined errors occur in several operating systems of the vehicle, the letter “U” will appear on the display. The letter designation is followed by a number.

The zero indicator is indicated by the OBD-2 code. Numbers 1 and 2 show the company code, and the third digit is responsible for the backup code. The subsequent set of numbers conditionally shows the place where errors were detected during diagnostics. A zero code indicates the exhaust system. Number 1 indicates the fuel system, number 2 indicates the air supply system.

If there is a malfunction in the ignition, then the number 3 will appear. If there are problems with additional control, the number 4 will appear. If there are malfunctions in the idle speed, then the number 5 is responsible for this, and if there are problems in the ECU, the number 6 will appear. Numbers 7 and 8 are associated with the transmission In the general code, the very last two digits indicate the error number in the operation.

What does code P0507 mean?

Trouble code P0507 is triggered when the engine idle speed is higher than expected. All modern engines have a desired idle speed - usually between 600-1000 rpm.

The control unit uses position sensing and throttle adjustment to achieve these speeds. If the idle speed exceeds these set values ​​and the maximum adjustment zone, the control unit will generate this error code.

Code P0507 is a common code for vehicles equipped with Electronic Throttle (E-Gas). Newer vehicles usually use E-gas.

The throttle valve is only called electronic. It replaces the old throttle body with a cable between the gas pedal and the throttle body.

The electronic throttle body uses sensors on the gas pedal and an electric motor in the throttle body to provide the desired acceleration. But this does not mean that this error code must necessarily be related to a faulty throttle valve. It can also have many other causes.

Self-diagnosis of the instrument cluster Kalina/Priora

Decoding error codes in the dashboard:

How to reset errors on Kalina? You can reset the errors yourself using the on-board computer, or contact a service station with special diagnostic equipment.

Let us remind you that you can find detailed photo reports in the Lada Kalina repair category.

Self-diagnosis

Let's look at the decoding of combinations of faults that you can read when checking the Lada Priora yourself.

The arrows on the dashboard move to maximum values ​​when performing self-diagnosis of the vehicle, and all icons on the panel are lit.
Please note: if the button for switching functions of the on-board computer is not pressed for more than 10 seconds, the dashboard will return to the operating state.

Symptoms of malfunction

The main driver symptom of P0222 is the MIL (Malfunction Indicator Light) illumination. It is also called Check engine or simply “check light”.

They can also appear as:

1. The “Check engine” warning light on the control panel will light up.
2. Unstable or low idle speed.
3. Increased engine speed at idle.
4. The engine stalls or has trouble starting.
5. The motor runs unevenly (pulsates).
6. There is no response to the gas pedal.

Other symptoms may also be present.

Prior error codes on the dashboard

Using the built-in controller, drivers can identify the main error codes for Priors 8 and 16 valves on their own. The procedure is carried out using a built-in computer or a connected device. Almost all modern cars are equipped with a system of various sensors that monitor the condition of automotive components. The bottom line is that the functionality of many working units directly depends on the correct functioning of the existing sensors.

On the other hand, turning off some indicators may not affect the operation and movement of the car, and malfunctions are detected much later, when the negative consequences of deactivating the sensors appear. Symptoms of the indicators turning off include unstable engine operation, excessive fuel consumption, and excessive wear of parts.

Description of error P0480

The cooling fan is electrically controlled by the engine control unit via a relay based on sensor readings:

• — Engine Coolant Temperature (ECT) Sensor
• — Incoming air temperature (IAT) sensor
• — Air conditioning selector switch
• — Air conditioning refrigerant pressure sensor A/C
• — Vehicle Speed ​​Sensor (VSS)

The ECM controls the fan by completing a control circuit that turns on the fan relay. The cooling fan relay turns on when the following conditions are met:

• Engine coolant temperature reaches 106°C (223°F) or more.
• The air conditioner clutch engages.
• The vehicle speed is less than 60 km/h.

The cooling fan relay turns on regardless of vehicle speed when the following conditions are met:

• -Engine coolant temperature has reached 151°C (304°F) or more.
• High refrigerant pressure in the air conditioning system.

Self-diagnosis using BC

The owner can identify the main error codes of Priora 8 and 16 valves using the built-in controller and on-board computer (BC), without resorting to the services of car service diagnosticians. To do this, you must activate the vehicle testing option. The arrows on the instrument panel move to the maximum possible position. Further manipulations are performed in the following sequence:

Checking with a plug-in tester

More accurate and comprehensive diagnostics can be performed using a connected computer or a special tester. However, the data displayed on the screen is alphanumeric. The letters have the following meaning:

In addition, the number 0 means OBD code 2, numbers 1 and 2 indicate the enterprise code, and 3 is the backup password.

Basic ignition system

(the letter P precedes the digital designation):

Fuel-air system

(the letter P is located before the numbers):

In principle, diagnostics using BC makes it possible to identify the main faults. Basic error codes for Priora 8 and 16 valves using a plug-in tester provide significantly more information. To understand it, you should study the decoding of indicators, which is not so difficult.

Modern Lada model

Like any modern foreign car, the Lada Priora has many different sensors installed. The condition of important vehicle systems depends on their correct operation. The problem is that if some sensors fail, the Priora can continue to move. Faults of this kind can lead to increased fuel consumption, unstable engine operation, and increased wear of parts, but the car will drive, and you will only find out about the fault when it means you have to make expensive repairs.

In order not to go into the engine compartment with a multimeter, the Priora has a controller that allows you to check faults using a special tester, a plug-in or built-in on-board computer. In order to diagnose the systems, just press 2 buttons and look at the error codes.

Description and meaning of error P0422

This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles. While general, specific repair steps may vary depending on the make/model. A vehicle's catalytic converter (catalyst) helps improve tailpipe emissions by oxygenating the exhaust gases. It helps convert carbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) into water vapor (H20), carbon dioxide (CO2), and nitrogen (N). The PCM (Powertrain Control Module) monitors catalyst efficiency through the catalyst post oxygen sensor. This sensor is mainly used for this purpose. It should shift much slower than the front oxygen sensors. If at any time the PCM detects that the catalytic converter O2 sensor is switching too quickly (without indicating any change between the input and output of the catalytic converter), then it interprets this as the catalyst not functioning properly. Bank 1 is the side of the engine with cylinder number 1.

Diagnostics using the built-in BC

To view the error codes, you need to find the daily mileage reset button on the dashboard, press it and, holding it, turn the ignition key. The self-diagnosis mode will turn on. All arrows on the instruments should move from minimum to maximum values ​​and back, and all positions on the LCD display should light up. You need to look: if any position does not light up or the arrow on any device does not move, then you should check the corresponding sensors, their networks or display for malfunctions.

Priora on-board computer

In the same mode, press any button for switching modes of the built-in BC 2 times, after which digital codes may appear on the liquid crystal display:

Many drivers ask how to reset error codes on a Lada Priora. Perhaps their built-in BC is faulty, since a working on-board computer automatically exits the diagnostic mode after 30 seconds if you do not press any control buttons.

On which cars is this problem most common?

The problem with code P0222 can occur on different machines, but there are always statistics on which brands this error occurs more often. Here is a list of some of them:

• Chevrolet (Chevrolet Aveo, Cruze, Lacetti)
• Daewoo (Daewoo Matiz)
• Ford (Ford Ranger, Focus)
• Hyundai (Hyundai Solaris)
• Jeep (Jeep Grand Cherokee)
• Kia (Kia Sid)
• Land Rover (Land Rover Range Rover)
• Mazda (Mazda 6)
• Mercedes
• Mitsubishi (Mitsubishi Lancer)
• Nissan (Nissan Pathfinder)
• Opel
• Peugeot
• Skoda (Skoda Octavia)
• Ssangyong
• Subaru
• Toyota
• Volkswagen (Volkswagen Passat, Polo Sedan, Tiguan)
• VAZ 2114
• Gazelle
• Lada Granta, Kalina, Niva, Priora
• UAZ Patriot

With fault code P0222, you can sometimes encounter other errors. The most common are the following: P0121, P0122, P0123, P0221, P2100, P2105, P2106, P2135, P2160, U0151, U1900.

Checking using a connected computer or tester

Driver Information Panel

Checking system malfunctions using connected devices gives more accurate results, but at the same time requires deciphering special codes. For example, the monitor displays code p0441 or p0130 or error p0422. Oh, these car manufacturers, in human language they could write “replace the oxygen sensor” instead of P0130 or “check the canister valve” instead of P0441. But nothing can be done, the Lada Priora is also intended for export, so it is easier to write p0441 in the program than to give explanations in Russian, Kazakh, Arabic, Armenian and 10 other languages. And then attach special tables that indicate the meaning of certain codes. Just look at them and everything will become clear. But these tables are not included with the operating instructions. Either way, you can check them out below.

All fault codes for Lada Priora car systems consist of 5 characters. Here is a breakdown of Prior's errors.

The Latin letter comes first:

The system indicates an error

The next digit indicates the system in which the malfunction was found:

The last 2 digits indicate the serial number of the fault.

How to Troubleshoot or Reset Trouble Code P0222

Some suggested steps to troubleshoot and fix error code P0222:

1. Read all stored data and error codes using an OBD-II scanner. To find out when and under what circumstances the P0222 error appeared.
2. Clear the error codes from your computer's memory and test drive the vehicle to see if P0222 appears again.
3. Visually inspect the electrical wires and connections related to the throttle position sensor “A” for looseness or damage.
4. Compare the readings of the throttle position sensors “A” and “B” using a scanner, and if necessary, replace the faulty sensor.
5. Clear the error code from your computer memory again and test drive the vehicle to find out if the problem is resolved.

Diagnosis and problem solving

Carefully check the Throttle Position Sensor (TPS), wiring connector and wiring for opens, etc. Repair or replace as necessary to resolve P0222.

Check the voltage at the TPS (see your vehicle's service manual for more information). If the voltage is too low, this indicates a problem. Replace the sensor if necessary.

If recently replaced, the TPS may need to be adjusted. On some vehicles, installation instructions require proper alignment or alignment (see repair manual for details).

If there are no symptoms, the problem may be intermittent and cleaning the code may temporarily resolve it. In this case, you should definitely check the wiring to make sure that it is not rubbing, worn out, etc.
