Hva betyr feilkoden?
The control module receives a faulty signal from the lambda probe. The fault may be in the probe itself, or in the connector or signal wire, where an open or short circuit can cause it.
Mulige årsaker
- Defective lambda sensor
- Incorrectly connected connector, or an open or short circuit in the signal wire
Hva du kan gjøre
- 1Check that the connectors to the control module and the lambda sensor are secure and free from oxidation and contact resistance.
- 2Check the wires from the lambda sensor for breaks. With a multimeter you can check that the signal wire is not open or shorted to ground or voltage.
- 3If you have a diagnostic tool, read the lambda value in live data. See whether it swings between rich and lean once the engine is warm.
- 4If no fault is found in the connectors or wiring, the lambda sensor needs replacing. Have a workshop do this.
Symptomer du kan merke2
- The malfunction indicator lamp lights up
- Poor performance
Hva feilen kan påvirke2
- The engine runs only on a rich mixture of fuel and air

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
