Was bedeutet der Fehlercode?

The engine control module (ECM) compares the signal from the front 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.

Mögliche Ursachen

Short circuit to voltage in the wiring to the temperature sensor
Damaged temperature sensor

Was Sie tun können

1Read out the fault code, erase it and check whether it returns at the next ignition on
2Switch off the ignition and check the connector to the front temperature sensor 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 to the sensor 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 replace it if needed

Symptome, die Sie bemerken können1

The check engine lamp lights or behaves abnormally
