Hva betyr feilkoden?
The oxygen sensor gives the engine control module information about the fuel and air mixture. The code is set when the module detects that the sensor's calibration signal is wrong, here too low. The fault can only be checked when the sensor is calibrated, which is a workshop task.
Mulige årsaker
- The signal lead is short-circuited to ground
Hva du kan gjøre
- 1Check the connector to the oxygen sensor for loose connections and damage
- 2With the ignition off, use a multimeter to check that the signal lead from the oxygen sensor is not short-circuited to ground
- 3Look for chafing or pinch damage on the signal lead where it may have touched ground
- 4Have a workshop check the oxygen sensor during calibration if the fault remains after the wiring check
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- The engine control module uses the last measured value
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
