Hva betyr feilkoden?
This code is a collective code for fuel adaptation faults on bank 1, and it is set when one of the underlying adaptation codes is stored in two consecutive driving cycles. Although the code is named for a signal that is too high, the underlying cause is what needs finding, because the code is always set together with one of them.
Mulige årsaker
- Consequential fault from an underlying fault code for adaptive lambda regulation on bank 1
Hva du kan gjøre
- 1First find and fix the root fault among the underlying fault codes for adaptive lambda regulation on bank 1
- 2Clear this code only once the root fault is fixed, then road test the car to check that it does not return
- 3Have a diagnostic tool? Read all stored fault codes and see which lambda-related codes are stored at the same time
Symptomer du kan merke1
- The malfunction indicator lamp (MIL) comes on
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
