At speeds above 4000 rpm, misfires may be stored. Erase the fault memory and repeat the test.
NOTE:
- If a fault is detected, it is only recorded in the fault memory after 6,000 ignitions (at idling speed approx. 3 minutes waiting time).
- It is important to observe the oxygen sensors during acceleration with wide-open throttle or to record their behaviour with the data logger.
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).
Diagnosis/troubleshooting - all naturally-aspirated models
NOTE: The DTC only covers electrical faults here.
Diagnostic conditions
- Battery positive voltage between 10 V and 16 V
- Exhaust temperature less than 800 锟斤拷C
- Oxygen sensor heating switched on for at least 120 seconds
NOTE: DTC P0132 is stored by the DME control module when the sensor voltage is continuously above 1.5V for more than 5 seconds
Possible cause of fault
- Short circuit to B+ in signal wire
- Oxygen sensor faulty
- Control module faulty
Affected pins
DME control module connector II, pin 10 and oxygen sensor jack, bank 2, pin 3
DME control module connector II, pin 16 and oxygen sensor jack, bank 2, 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).
