Error codes on the 16 valve VAZ-2112: self-diagnosis on the dashboard

On Lada cars produced in 2001 - 2007 and subsequent ones, the manufacturer installs a BC capable of performing a self-diagnosis procedure. Thanks to this, the motorist can independently read the fault codes of the VAZ 2112 and determine the presence of a breakdown. Errors are reflected on the instrument display in the form of one or two-digit codes. The disadvantage of the procedure is the lack of an accurate determination of the location of the breakdown - self-diagnosis is only capable of a general determination of the circuit. Faults can also be read using additional equipment. The connected scanner provides detailed information about the specific location of the breakdown.

How to replace the coolant sensor

To work on removing the coolant temperature sensor, you need to remove at least part of the antifreeze from the system. The easiest way is to drain it from the radiator, but you will have to unscrew the plug on the cylinder block, since the sensor is located not far from this unit. Let's figure out how to drain the liquid from the system completely:

Remove the negative terminal of the battery. Remove the middle mudguard in the engine compartment.
Close the cap of the expansion tank tightly, place a container with a volume of at least 6 liters under the hole in the radiator, and remove the plug. To make the fluid drain faster, unscrew the cap on the expansion tank.
To remove antifreeze from the cylinder block, you must additionally unscrew the plug on it. The exact instructions will depend on the number of valves in the engine. If your Kalina has an eight-valve system with a traction drive gearbox, then you need to find the drain hole under the ignition coil on the front side of the cylinder block. After this, place the container under it and remove the stopper. After this, all you have to do is unscrew the sensor, having first disconnected the block with wires from it.

If your Lada Kalina has a sixteen-valve system with a cable-driven gearbox, then you will need to remove the starter before draining the antifreeze. If you do not do this, you will fill this unit with coolant. The starter is held on by three bolts, but before removing them you need to disconnect the wiring.

Once you have removed the fluid, replace the plugs. Now you can start replacing the sensor itself. Remove the wire block from it, if you did not do this to check, then unscrew the controller using a 21 key. In its place you need to install a new element, having previously treated the thread with heat sealant. Connecting the wiring to the new sensor is not at all difficult - the chips have special notches for proper installation.

Return fluid to the cooling system through the expansion tank. It is necessary to use new antifreeze; the manufacturer recommends using red “Felix” for this. Then reassemble, warm up the engine to bleed the system. Check to see if antifreeze is leaking from the plugs or through the threads of the sensor. After the engine has warmed up, touch the pipes - they should all become warm. If everything is normal, you can begin testing the system and making a test drive. If the error persists, then most likely the on-board computer provided false information.

In the event of malfunctions in the operation of the vehicle, the engine electronic control unit (ECU) stores errors in memory. In the future, Kalina ECU errors can be read using an on-board computer or special equipment for car diagnostics. In addition to controller error codes, it is possible to perform Kalina self-diagnosis on the dashboard.

Advice

: To read errors in electronic units, car owners often use the ELM327 adapter (buy on Ali) and the OpenDiag application in their smartphone.

How to check the sensor

Since the cause of error 4 on the Lada Kalina is not always the failure of the controller, you need to learn how to diagnose it. First of all, inspect the wiring; if there are no breaks in it, then you need to move on to checking the sensor itself. Follow the instructions:

Turn off the ignition and disconnect the wire connector from the coolant sensor. For the convenience of motorists, the block is marked “AB”.
Place the probes of the electronic tester on contact B of this block and on engine ground. If the power circuit is not broken, the tester will show a voltage of 4.8 to 5.2 V. Otherwise, you need to check the power circuit.
If the device shows sufficient voltage in the circuit, then you need to check the controller itself. To do this, place the tester probes on contact A and engine ground. Switch it to resistance measurement mode. If the circuit is grounded, the device will show a resistance of less than 1 ohm.
The following measurements should be carried out on a warm and slightly cooled engine. The probes of the device are placed on the contacts of the sensor itself to measure its resistance. It is also important to know the temperature of the coolant; the hotter it is, the lower the resistance should be. The maximum resistance is achieved at negative temperatures, and at 100 degrees it is minimal - 180 Ohms.

If the sensor does not pass the warm-up test, it must be replaced. There are more complex ways to check the sensor, but to do this you will have to unscrew it and test it.

Diagnostics using a scanner

The method involves connecting an external computer with the program installed. This opens up more opportunities for car diagnostics. In this case, error codes for VAZ 2110 and VAZ 2112 consist of 5 characters.

Letter part:

P – failure or malfunction of the power plant, transmission;
B – body systems are damaged;
C – a problem has been detected in the vehicle’s chassis;
U – violation of pairing of different modules.

First digit:

0 – general value;
1/2 – manufacturer code;
3 – reserve.

Second digit:

1-2 – violation in the air-fuel mixture supply devices;
3 – malfunction of the ignition units;
4 – atmospheric emissions control device;
5 – malfunction of the engine speed or engine speed meters;
6 – failures in electronics;
7-8 – malfunction of the gearbox module;
9-0 – reserve unit.

The last two digits give the serial number of the breakdown and its location.

Prevention of breakdowns of electrical appliances

To prevent breakdowns of electrical circuits, you must follow a number of simple rules.

Periodically check the contact connectors for oxidation or overheating. Rust disrupts the passage of impulses, which can be read by instruments as damage to the unit.
Once a year, treat contacts with special oils. Lubricants prevent moisture from entering metals, which prolongs their service life.
Replace dry wires in a timely manner. Cracked insulation can cause a short circuit.

Errors on the VAZ 2110 (2112) panel provide the user with complete information about the condition of the vehicle’s components and assemblies. If you know the decryptions, the driver can independently fix the breakdown of the vehicle electronics.

Checking the coolant temperature sensor

I will not show tables with sensor resistance values at a certain temperature, since I think this method of checking is not entirely accurate. The simplest and fastest way to check the DTOZH is to simply remove the chip from it. The engine will go into emergency mode, the fan will turn on, and the fuel mixture will be prepared based on the readings of other sensors. If at the same time the engine begins to work better, then the sensor definitely needs to be changed.

For the next check of the coolant temperature sensor, you will need diagnostic equipment. First, you need to check the temperature readings on a cold engine (for example, in the morning). The readings must correspond to the ambient temperature. A slight error of 3-4 degrees is allowed. And after starting the engine, the temperature should rise smoothly, without jumping between readings. Those. if the temperature was 33 degrees, and then suddenly became 35 or 36 degrees, this indicates a sensor malfunction.
