Hva betyr feilkoden?
The code concerns the long-term correction of the fuel mixture, which is controlled by the oxygen sensor. The correction can reach its upper limit, when the mixture is too lean, or its lower limit, when it is too rich. The causes therefore differ depending on which way the correction is going.
Mulige årsaker
- Air leakage in the intake system
- Air leakage in the exhaust system
- Fuel pressure that is too low or too high
- Defective oxygen sensor
- Leaking injectors
- Defective mass air flow (MAF) sensor
Hva du kan gjøre
- 1Look for air leaks in the intake system, for example in hoses and connections
- 2Look for leaks in the exhaust system, especially at the joints
- 3Check the oil level on the dipstick, and whether the oil appears diluted or contaminated
- 4If you have diagnostic equipment, read the long-term correction at idle and see whether it is steady
- 5Have a workshop check the fuel pressure, the injectors, the mass air flow sensor and the oxygen sensor if the fault remains
