Oxygen Sensing Adaptation, Idle Range, Bank 2 - Below Limit
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 锟斤拷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.
