Hva betyr feilkoden?
The engine control module monitors the front oxygen sensor by checking its signal. The code is stored when the sensor only indicates air and no fuel and air mixture. The sensor may be installed incorrectly in the exhaust, or it may be damaged.
Mulige årsaker
- Oxygen sensor fitted incorrectly
- Damaged front oxygen sensor
Hva du kan gjøre
- 1Check that the oxygen sensor is correctly fitted in the exhaust system
- 2Check the sensor connector for contact resistance, open circuits and oxidation. Do not use rust solvent or grease in it
- 3If the fitting and connector are in order but the fault remains, have a workshop try a new oxygen sensor
