Hva betyr feilkoden?
The fault is registered as intermittent, meaning it occurred at some point but may not be present now. The engine control module (ECM) has registered that the current from the front oxygen sensor is too low. The fault may be caused by a connector that is only occasionally making poor contact.
Mulige årsaker
- Signal wire short-circuited to supply voltage
- Defective front oxygen sensor
- Occasional poor contact in the connector at the sensor
Hva du kan gjøre
- 1Read and clear the fault code and check whether it returns
- 2With the ignition on, gently move the connector at the front oxygen sensor and see whether the fault follows
- 3Check the connector for contact resistance and oxidation, and do not use penetrating spray or grease in it
- 4Check the wire for chafing and for short circuits to supply voltage
- 5If the fault returns, have a workshop check the oxygen sensor
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- Fuel trim control is switched off
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
