Hva betyr feilkoden?
The heater supply to the rear lambda sensor on bank 1, sensor 2, is shorted to battery voltage. The engine control module regulates the heating and sets the code when the signal is too high while the heating is active. Lambda control is switched off.
Mulige årsaker
- Signal wire shorted to supply voltage
- Faulty rear lambda sensor
Hva du kan gjøre
- 1Read the code, clear it and road test the car to see whether it returns
- 2Use a multimeter to check that the wire to the rear lambda sensor is not shorted to supply voltage
- 3Check the connector at the lambda sensor, and do not use rust-release spray or grease in the connector
- 4Have a workshop check the resistance of the lambda sensor, and replace it if it is damaged
Symptomer du kan merke1
- Check engine lamp lit or behaving abnormally
Hva feilen kan påvirke1
- Lambda control is switched off
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
