P1130

361 Oxygen Sensing Adaptation, Idle 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

Possible fault cause
- Incorrect signal from MAF sensor
- Fuel pressure too high
- Fuel injector leaking
- EVAP canister purge valve open

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.
- For vehicles in the USA, the upper load range will probably not be reached. The only case in which a fault could be stored is during driving while towing a trailer or caravan on a hill.
- Contrary adaptation values in connection with misfiring point to incorrectly adjusted control times See check control times and adjust if necessary.
- If the fuel tank reserve light is switched on, no fault is entered.

361 Oxygen Sensing Adaptation, Idle 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
- PCV valve leaks
- Cap of oil filler neck not closed correctly or seal is damaged

Diagnosis/Troubleshooting

NOTE:
- Air leaks ahead of the oxygen sensors can lead to a fault in adaptation See Check exhaust system for leaks.
- Contrary adaptation values in connection with misfiring point to incorrectly adjusted control times See check control times and adjust if necessary.
- If the fuel tank reserve light is switched on, no fault is entered.
