Lada Kalina comes off the VAZ assembly line with a built-in central electronic control unit and an injection engine. All problems that arise in electrical and electronic systems are recorded by the control unit, stored in memory, and issued as a digital code.
Some errors are displayed on the screen of the combined instruments, and a more in-depth search for errors and their decoding is carried out by external devices, such as scanners or using computer diagnostics. Third-party devices are connected via the diagnostic connector. The fault codes on an 8 valve vehicle are identical to those on a 16 valve vehicle, with some additions.
Self-diagnosis
Before contacting a car service, you can independently determine in which of the nodes or on which of the highways the malfunction occurred. This can be done using self-diagnosis, when errors occurring in the electronic control unit are displayed on the control panel. Maybe you can fix it yourself, or at least understand what you are faced with and what to expect when contacting specialists.
This is a simple procedure. It is enough to reset the instrument data of the daily mileage by holding the Reset button and turning on the ignition. The devices will switch to test mode, during which the indicator lamps and backlights will light up, and the device arrows will move back and forth along the scales. On the steering column lever, on the right, menu items are switched, in which there is a self-diagnosis mode for devices. Information about the software version and digital error codes stored in the memory of the control unit will appear on the screen.
There are tables for deciphering errors. Exit from the self-diagnosis mode occurs within the next 30 seconds, during which no manipulations need to be performed.
Replacing lamps - nuances
Sometimes it is difficult to say which light bulb on model 2114 has lost its functionality. In this case, everything is pulled out and checked with a multimeter. For this:
- set the tester to ohms;
- Press one probe against the side of the base, and the second against the blotch installed at its lower end;
- If the arrow moves, then the filament coil is working.
It is important to remember that the described procedure is not suitable for diode lamps. A different operating principle is used here.
The multimeter must be switched to diode testing mode. The probes are connected in the same way, but during testing they change places - in one direction the current flows without restrictions, and in the other direction it is not allowed to pass at all.
A tester is required for one reason - the light bulb is very small and it is almost impossible to determine the serviceability of the filament purely by eye. The measuring device helps to quickly cope with the task.
Experienced car enthusiasts advise replacing all the lamps at once after disassembling the instrument panel, because they are inexpensive. Otherwise, there is a risk that one or more old ones will soon burn out, and all the work will have to be done again.
When the new lamps are installed, return the instrument panel to the interior, connect the wires to it, but do not fix it. Further:
- turn on the ignition;
- check how the backlight and indicators (handbrake, turn signals, etc.) function.
If everything turns out to be in order, then fasten the panel with screws.

How to choose the right service for diagnostic and repair work
In the age of computer technology, information about self-diagnosis behavior is widely available. Private salons and services are not uncommon, as are craftsmen working on the road. If a problem arises with the operation of your car, it is important to understand whether you can fix the problem yourself or whether it is better to seek the help of a professional. Not all workshops have licensing documents from the manufacturer or certification to provide services. The result of dishonest work will be poor functioning of the ECU or other components of the diagnostic system.
You have every right to demand documentation confirming the qualifications and professional level of employees, their ability to handle special equipment and the electronic system of the car. For computer diagnostics, it is important to have the appropriate equipment, for example, a stand with which work is carried out in parallel with a laptop. It is thanks to the stand that the information will be more accurate and a comprehensive picture of the condition of the machine will be revealed. You should not pay money to specialists who offer the service of flashing the on-board computer or controller to change the technical characteristics of the car.
Kalina error codes are a type of vehicle diagnostic information that every car owner needs to know. The fact is that with their help, self-diagnosis of the Lada Kalina is performed, and this allows you to identify the malfunction of one or another component without waiting for the car to seriously break down.
Diagnostics using third-party devices
For a more detailed check of the vehicle's performance, scanners and computers are used. They are connected to the diagnostic electrical connector (socket) located on the standard panel. Malfunctions are issued in the form of a standard set of alphanumeric codes, consisting of one letter and four numeric designations. The letter indicates specific nodes in which the malfunction occurred.
B - detects problems with electronics inside the cabin;
C - indicates defects in the chassis design;
P - errors in the engine control module or transmission;
U - loss of communication between electronic modules.
The letter designation is followed by four characters:
- the first character indicates a standard code established by engineers at the Automobile Association;
- the second character records personal codes set by manufacturers;
- the third character indicates which system the malfunction occurred in:
1-2 - in the fuel and air system;
- in the ignition system;
- in a secondary emission control system;
- in the speed control controls or when the load is off (XX);
- on-board computer system and wiring;
7-8 - errors in the operation of the gearbox;
9.0 - reserve;
- the fourth and fifth symbols are considered together to more accurately locate the point of failure.

Trouble P0441 - Evaporative Emission System - Incorrect Purge Flow
Trouble code P0441 indicates a problem with the evaporative emission system. Other error codes may also appear along with this code.
What does P0441 mean?
Trouble code P0441 indicates that the ECM has detected incorrect purge flow in the evaporative emission control system. If the purge flow is incorrect, the Check Engine Light will illuminate on the vehicle's dashboard. The ECM uses a vacuum switch to determine purge flow.
Causes of error P0441
- Missing or damaged fuel tank cap
- Vacuum switch malfunction
- Damage to the fuel vapor recovery system tubes
- Short circuit or broken wires
- Blockage of the fuel vapor recovery system
- Fuel vapor leak
- Purge valve malfunction
What are the symptoms of a P0441 code?
Typically, when the P0441 error appears, drivers do not notice any signs of its occurrence at all. In rare cases, you may smell fuel inside or outside the vehicle.
How does a mechanic diagnose a P0441 code?
- First, the mechanic will connect the OBD-II scanner to the vehicle's diagnostic port and read all the stored data and error codes.
- He will then clear the error code from the ECM and test drive the vehicle.
- If P0441 appears again, have a mechanic visually inspect the evaporative emission system.
- The mechanic will then check the fuel pressure sensor in the fuel tank for damage.
- He will also check the fuel cap.
- He will then check the operation of the vacuum switch and purge valve.
- If no problem is found, the mechanic will perform a thorough check of the evaporative emission system to check for leaks.
Common errors when diagnosing code P0441
The most common mistake when diagnosing a P0441 code is not following the diagnostic protocol, as well as not performing a smoke leak test.
Also, mechanics often assume that the problem is a damaged fuel cap, but do not perform thorough diagnostics to verify this. It is imperative to check the fuel tank cap for leaks, for example using a vacuum tester.
How serious is P0441?
Error P0441 is not considered very serious. However, it should be noted that if the Check Engine Light comes on, the vehicle will most likely fail an emissions test. Also, when this error appears, drivers may smell fuel.
What repairs can fix the P0441 code?
- Replacing the fuel tank cap
- Repairing a leak in the fuel vapor recovery system
- Repair or replace damaged evaporative emission system components
- Replacing the purge valve
- Vacuum switch replacement
- Repair or replacement of wires
Additional comments for troubleshooting P0441
To properly diagnose the P0441 trouble code, a mechanic will need an advanced OBD-II scanner. It is necessary to check the operation of the vacuum switch and purge valve, as well as to carry out certain tests.
