Was bedeutet der Fehlercode?

The ECM gets mixture information from the oxygen sensor across different load ranges and corrects deviations with self-learning adaptations. The code is set when the mixture becomes too rich, so that the adaptations for bank 2 reach an end position. The fuel adaptation is then too high towards rich, and the control module treats this as a fault.

Mögliche Ursachen

Clogged air filter
Oil level too high
Contaminated engine oil, for example with petrol from many short journeys
Leaking fuel injectors
High fuel pressure
Damaged mass air flow sensor

Was Sie tun können

1Read the code, clear it and road test the car to see whether it comes back
2Check that the air filter is not clogged
3Check the oil level sits between the dipstick marks
4Check the intake system for blockages and loose parts, such as a loose air control in the air filter housing
5If you have a diagnostic tool: see whether the fuel adaptations for bank 2 are clearly shifted towards rich across several areas
6Have a workshop check the fuel pressure and the mass air flow sensor with diagnostic equipment

Symptome, die Sie bemerken können3

Check engine light (MIL) on
Poor performance
The engine misfires
