Co oznacza ten kod błędu?
To keep the fuel mixture right on bank 2, the engine control module has had to correct it heavily, and the long-term correction has nearly reached its limit at lower part load. Possible causes are air leaks in the intake or exhaust, low fuel pressure or a sensor that reads wrongly.
Możliwe przyczyny
- Air leakage in the intake system
- Air leakage in the exhaust system
- Low fuel pressure
- Damaged heated oxygen sensor on bank 2
Co możesz zrobić
- 1Read and note the code, then clear it and road test the car
- 2Inspect the intake manifold and hoses for cracks, loose clamps and leaks
- 3Check that the fuel lines are not leaking and that there is no smell of fuel in the engine bay
- 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 bank 2 oxygen sensor value in live data at idle and see whether it swings between rich and lean
- 6If the fault remains, have a workshop measure the fuel pressure and replace the bank 2 oxygen sensor if needed
