P2A03
P2A03Diagnosis information - Control unit DME (DFI)
Oxygen sensor in front of catalytic converter Bank 2 , Electrical fault
NOTE:
Separated plug connection = open reference-air duct.
Damage to oxygen sensor.
- DO NOT use spray, grease, fluid or similar products on the oxygen sensor plug connections.
INFORMATION
- Do not interchange the oxygen sensor in front of the catalytic converter with the sensor behind the catalytic converter as this will result in implausible fault entries.
- The plugs themselves are coded and cannot be interchanged.
Diagnostic conditions
- Engine running > 30 Second(s) , at:
- Exhaust gas temperature > 100 °C (°F)
- Oxygen sensor in front of catalytic converter ready for operation
- without Overrun phase(s)
Possible fault causes
- Fault in area : Oxygen sensor in front of catalytic converter Bank 2
Fault setting condition(s)
- Temperature implausible (Oxygen sensor in front of catalytic converter)
Fault effects
- Since oxygen sensing is interrupted the moment a fault is detected, the DME (DFI) control unit stores this fault as information.
- Other faults have been entered
- The vehicle must be driven in the same driving cycle (without ignition reset) for this purpose.
