P0041Diagnosis information - DME V6 DFI
Oxygen sensors behind catalytic converter interchanged
NOTE: Do not use contact spray on the oxygen sensor's plug connections as this will result in irreparable damage to the lines (blockage of reference air duct).
NOTE: Do not interchange the oxygen sensor ahead of catalytic converter with the sensor behind the catalytic converter as this will result in implausible fault entries.
Diagnostic conditions
- Battery positive voltage between 10 V and 16 V
- Time after engine starts > 10 seconds
- Lambda control active
Possible fault causes
- Oxygen sensors downstream interchanged
- Reversed line polarity
