Hva betyr feilkoden?
The ECM checks the electrical resistance in the heater circuit of the rear oxygen sensor on bank 1. If the resistance is outside the permitted limits, the control module treats it as a fault. Poor contact is the usual reason, although a damaged oxygen sensor can also cause it.
Mulige årsaker
- Contact resistance and oxidation in the connections
- Damaged rear oxygen sensor
Hva du kan gjøre
- 1With the ignition off, unplug the rear oxygen sensor connector and check the contacts for resistance and oxidation, fixing them as needed
- 2If the fault remains after erasing codes and a test drive, have a workshop check and replace the rear oxygen sensor
Symptomer du kan merke1
- Malfunction indicator lamp (MIL) lights up
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
