Co oznacza ten kod błędu?

The oxygen sensor correction of the fuel mixture on bank 2 has nearly reached its upper limit at idle, which means the engine control module has to add more fuel than normal. The air and fuel are not in balance, and the fault can lie in an air leak in the intake or exhaust or in a damaged oxygen sensor.

Możliwe przyczyny

Intake air leakage
Air leakage in the exhaust system
Damaged heated oxygen sensor on bank 2

Co możesz zrobić

1Check the intake system for leaks, including the hose to the brake booster and the EVAP valve hoses
2Check that hoses and connections on the intake side are secure and intact
3Check the exhaust system for leaks at joints and seams
4Have a diagnostic tool? Read the mass air flow correction factor with the engine at idle and check that the value looks plausible
5If the fault remains, have a workshop look for leaks with smoke testing and check the bank 2 oxygen sensor
