Hva betyr feilkoden?
The engine control module (ECM) adjusts injection from the lambda sensor reading. The code is set when the correction has to be close to its maximum at idle and the signal is too low. The fault may lie in leaking injectors, the mass air flow sensor, the engine oil or oil level, the lambda sensor or the calculated ethanol content.
Mulige årsaker
- Leaking injectors
- Damaged mass air flow (MAF) sensor
- Contaminated engine oil
- Oil level too high
- Damaged heated oxygen sensor (HO2S)
- Incorrectly calculated ethanol content
Hva du kan gjøre
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Have a workshop measure the fuel and residual pressure to check whether the injectors leak
- 3Look at the dipstick, where the oil should sit between the two marks, and check the oil for dirt
- 4Check the mass air flow sensor for damage and dirt
- 5Think back on how the car has been refuelled; and have a workshop check the ethanol calculation if it may be wrong
- 6Replace the lambda sensor if nothing above cures the fault, since a damaged lambda sensor can also set this code
Symptomer du kan merke4
- The malfunction indicator lamp (MIL) is lit
- The engine stalls when accelerating
- The idle is uneven
- The engine does not start and only cranks
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
