P1108

Oxygen Sensing Adaptation, Lower Load Range, Bank 2 - Below Limit

Diagnosis conditions
- Oxygen sensing system active
- Time elapsed after engine start-up: 250 to 350 seconds (USA)
- Time elapsed after engine start-up: 302 to 402 seconds (RoW)
- Engine temperature greater than 60 °C

- Fuel injector leaking

Diagnosis/Troubleshooting

NOTE:
- If DTC P0445 (fuel tank vent valve - short to ground) is stored, correct this fault first. An open EVAP canister purge valve can lead to the lean threshold being reached.
- If the fuel tank reserve light is switched on, no fault is entered.
