Hva betyr feilkoden?
The rear lambda sensor has a heater that brings it up to temperature quickly after a cold start. The control module checks the voltage in the heater circuit and logs a fault when it does not match whether the heater is on or off. The cause is most often an open wire or a wire shorted to ground, but a damaged sensor can also trigger it.
Mulige årsaker
- Open circuit in the heater circuit signal wire
- Heater circuit signal wire shorted to ground
- Damaged rear lambda sensor, bank 1
Hva du kan gjøre
- 1Read, clear the code and road test to see whether it returns
- 2Check that the connector at the rear lambda sensor is fully engaged and free from oxidation
- 3Follow the cable from the sensor and look for chafing, pinched sections and loose clips
- 4With the connector unplugged, use a multimeter to check that the heater circuit wire has no connection to ground (the body)
- 5If you have a diagnostic tool, compare in live data whether the rear sensor heater switches on and off at a cold start and when the engine is warm
- 6If the fault returns, have a workshop with diagnostic equipment check the wiring and the sensor
Symptomer du kan merke1
- Malfunction indicator lamp (MIL) lit
