Co oznacza ten kod błędu?

The code applies to bank 2, the cylinder row furthest to the rear. The ECM gets mixture information from the oxygen sensor across different load ranges, and the code is set when the mixture becomes too lean and the adaptations for bank 2 reach an end position.

Możliwe przyczyny

Too high ethanol content in the fuel
Air leak in the intake pipe
Air leak in the exhaust pipe
Low fuel pressure
Damaged mass air flow sensor
Incorrectly fitted or damaged oil dipstick, causing an air leak

Co możesz zrobić

1Read the code, clear it and road test the car to see whether it comes back
2Check the intake and exhaust systems for air leaks
3Check that the dipstick is seated correctly in its tube and that air does not leak around it
4If the fuel adaptations for bank 2 are clearly shifted towards lean at idle, this points to an air leak
5Have a workshop check the fuel pressure and the mass air flow sensor with diagnostic equipment
