Diagnostic conditions
- Engine start (Cold start + Catalytic converter heating measure)
- Engine temperature > -10 锟斤拷C (锟斤拷F)
- Engine running > 5 Second(s)
Possible fault causes
- Pre-delivery quantity or pressure in fuel low-pressure circuit too low
- Quantity control valve Faulty (in Fuel high-pressure pump)
- Fuel high-pressure pump Faulty
Fault setting condition(s)
- Deviation Fuel high-pressure > 20% ( Actual value - Nominal value ), at:
- Catalytic converter heating measure
P0056
P0056
Diagnosis information - Control unit DME (DFI)
Final stage Oxygen sensor heater Oxygen sensor behind catalytic converter Bank 2
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 > 10 Second(s)
- Oxygen sensor heater Active
Possible fault causes
- Loose contact or corrosion on connectors or lines
- Short circuit to B+/ground or open circuit in the line (Power supply or Activation)
- Oxygen sensor behind catalytic converter Bank 2 Faulty
