Co oznacza ten kod błędu?

The engine control module has had to correct the fuel mixture for the bank 1 oxygen sensor so much that the long-term correction has nearly reached its maximum at lower part load. The mixture is therefore far from the target, and the cause can be a leak in the intake or exhaust, low fuel pressure or a damaged sensor.

Możliwe przyczyny

Air leakage in the intake system
Air leakage in the exhaust system
Low fuel pressure
Damaged heated oxygen sensor on bank 1

Co możesz zrobić

1Clear the code and road test the car to see whether it returns
2Go over the intake hoses and connections for cracks, loose clamps and leaking spots
3Check the exhaust system for leaks at joints and seams
4Check that the hose to the brake booster and the hoses to the EVAP valve are intact
5Have a diagnostic tool? Follow the long-term fuel trim for bank 1 in live data at idle with the engine warm, and see whether it sits close to its extreme position
6If the fault remains, have a workshop measure the fuel pressure and check the oxygen sensor on bank 1
