02 Sensor Circuit
Diagnostic conditions
- Battery positive voltage between 10 V and 16 V
- Oxygen sensor heating switched on for at least 120 seconds
- Exhaust temperature between 200 锟斤拷C and 800 锟斤拷C
Possible cause of fault
- Oxygen sensor faulty
Affected pins
DME control module connector II, pin 11 and oxygen sensor jack, bank 1, pin 3
DME control module connector II, pin 17 and oxygen sensor jack, bank 1, pin 4
Diagnosis/troubleshooting
NOTE: Do not use contact spray on the oxygen sensor plug connections as this may cause irreparable damage to the wiring (contamination of the
oxygen sensor via the reference air channel).
