Hva betyr feilkoden?
The engine control module has detected that the front lambda sensor on bank 1 responds too slowly to changes in the fuel-air mixture. A healthy sensor follows these changes quickly, so when it lags, the control module cannot keep the mixture correct. Most often this is false air from leaks in the intake or exhaust system, though a damaged sensor can also cause it.
Mulige årsaker
- Air leak at the intake manifold
- Air leak at the exhaust manifold
- Damaged front lambda sensor, bank 1
Hva du kan gjøre
- 1Read, note and clear the code, then road test to see whether it returns
- 2Check that the connector at the lambda sensor is fully engaged and free from corrosion
- 3With the engine running, listen for hissing near the intake manifold and its joints, and look for loose hoses or clips
- 4When the engine is warm, listen for exhaust leaks at the exhaust manifold and its joints. A leak before the sensor lets in false air that the sensor picks up
- 5With a diagnostic tool, check how the sensor value follows the accelerator. A slow response confirms the fault but not its cause
- 6If the leak check finds nothing, have a workshop with diagnostic equipment decide whether the lambda sensor needs replacing
Symptomer du kan merke2
- Malfunction indicator lamp (MIL) lit
- Engine may start poorly or sometimes not at all
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
