Hva betyr feilkoden?
The engine control module has found that the front oxygen sensor on bank 1 incorrectly indicates a lean fuel and air mixture, so the fuel mixture adjustments become misleading.
Mulige årsaker
- Air leakage in the intake manifold
- Damaged front oxygen sensor on bank 1
Hva du kan gjøre
- 1Clear the code and road test to see whether it returns
- 2Check the intake manifold and its hoses for cracks and loose joints, since an air leak gives a lean mixture
- 3Check the oxygen sensor connector for play and oxidation
- 4If the fault remains, have a workshop replace the front oxygen sensor on bank 1
Symptomer du kan merke1
- The malfunction indicator lamp comes on
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
