- 1Check that the connectors to the rear temperature sensor are firmly seated and not oxidised
- 2Use a multimeter to check that the wiring to the sensor has no break and no short to ground (the body)
- 3If you have a diagnostic tool, read the rear sensor value with the ignition on and see whether it seems reasonable
- 4Read and clear the fault code, then switch the ignition on again to see whether it returns
- 5If the fault remains, have a workshop check the rear temperature sensor
