Co oznacza ten kod błędu?

The control module compares the signal from the rear temperature sensor in the catalytic converter with a calculated value and sets the fault if the signal is too high. The fault is checked when the ignition is switched on. The causes are wiring to the sensor that is shorted to voltage, or a damaged sensor.

Możliwe przyczyny

Wiring to the temperature sensor short-circuited to voltage
Damaged temperature sensor

Co możesz zrobić

1Read out the fault code, erase it and check whether it returns at the next ignition on
2Switch off the ignition and check the rear sensor connector for loose connections and oxidation
3Use a multimeter to check that the signal wire to the sensor is not shorted to voltage
4Also check that the supply wire is not shorted to voltage, and look for chafed wires near the exhaust pipe
5If the fault remains, have a workshop with diagnostic equipment check the sensor and the wiring
