Hva betyr feilkoden?
The code is stored when the long-term fuel trim for bank 2 has nearly reached its limit at lower part load, even though the code is named for a signal that is too low. The mixture then deviates strongly from the target, and the cause can be a leak, fuel pressure, injectors, the mass air flow sensor, the engine oil or a damaged sensor.
Mulige årsaker
- Air leakage on the intake side
- High fuel pressure
- Leaking fuel injectors
- Damaged mass air flow sensor
- Contaminated engine oil or oil level too high
- Damaged heated oxygen sensor on bank 2
Hva du kan gjøre
- 1Clear the code and road test the car to see whether it returns
- 2Check the intake system for air leakage, including the hose to the brake booster
- 3Look for fuel leaks at the fuel lines and note whether there is a smell of fuel
- 4Check that the oil level is between the min and max marks on the dipstick, and that the oil is not contaminated
- 5Have a diagnostic tool? Read the fuel trim for bank 2 in live data at idle, and see whether it is heading towards its upper limit
- 6If the fault remains, have a workshop measure the fuel pressure and check the injectors
Symptomer du kan merke1
- No noticeable symptoms for the driver
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
