358 Oxygen Sensing Adaptation, Lower Load Range, Bank 2 - Above 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

Possible fault cause
- Incorrect signal from MAF sensor
- Intake air system leaking
- Fuel pressure too low
- Volume supply of fuel pump too low
- Fuel injectors fouled

NOTE:
- Air leaks ahead of the oxygen sensors can lead to a fault in adaptation.
