Hva betyr feilkoden?
This code is a collective code for fuel adaptation faults on bank 2. It is set when an underlying adaptation code has been stored in two consecutive driving cycles, and it always comes together with one of them. Although the code is named for a signal that is too high, the root fault is what needs to be found.
Mulige årsaker

Hva du kan gjøre

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
