Three-digit combinations. LADA code errors

102

Malfunction of the mass air flow sensor. The cause of the problem may be a blockage of the device, sometimes it can be eliminated by cleaning the controller.

 

131

Failure of one of the oxygen controllers. A detailed inspection of all sensors, their contacts and heating devices is required.

 

134

No signal from the oxygen controller. The number of the sensor is not specified, as well as its location, so you need to check each device.

 

171

Depleted mixture in the cylinders of the power unit.

 

300

The microprocessor module detects accidental or multiple misfires in the engine cylinders.

 

327

Low level of the signal recorded in the control circuit of the detonation controller.

 

328

The signal detected in the detonation sensor control circuit is too high.

 

343

Malfunction of the camshaft position sensor, increased signal coming from the device.

 

501

Speed controller malfunction.

 

504

Incorrect signal from the brake pedal control. You need to check the contacts of the sensor for the integrity of the pins and clogging of the connector.

 

422

Low efficiency of the catalyst device. The cause of the problem may be a leak in the system.

 

441

Incorrect air flow through the adsorber purge valve.

The appearance of this code may be due to the following factors:

1. The power unit works for more than twenty minutes.
2. The engine operates at non-contact speed.
3. Diagnosis by the microprocessor module of the adsorber purge valve gave a negative result.
4. The control unit calculated that the amount of oxygen after the neutralizing device is much higher than the normalized value.

 

603

External RAM module error.

 

830

Malfunction of the controller mounted on the clutch pedal.
