The turbocharger's speed is calculated from various input variables.
P0050
P0050
Diagnosis information - Control unit DME (DFI)
Final stage Oxygen sensor heater Oxygen sensor in front of 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)
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 in front of catalytic converter Bank 2 Faulty
