En anglais:
P2187 Oxygen Sensing Adaptation, Idle Range, Bank 1 (RKAT1) - Above Limit
P2189 Oxygen Sensing Adaptation, Idle Range, Bank 2 (RKAT2) - Above Limit
Possible fault cause
- Incorrect main charge signal
- Intake air system leaking
- Fuel pressure too low
- Volume supply of fuel pump too low
- Mechanical fault in injection valves
- PCV valve leaks
- Cap of oil filler neck leaking
- Leaks in exhaust system
- EVAP canister purge valve mechanically faulty (hangs open)
- EVAP canister purge valve output stage faults
