Was bedeutet der Fehlercode?

The engine control module (ECM) compares the reading from the temperature sensor ahead of the catalytic converter with a calculated value. The code is set when the sensor gives an incorrect value, and a signal wire in contact with voltage can then be the cause. A damaged sensor or an incorrect reading from the mass air flow meter can also trigger it.

Mögliche Ursachen

Signal wire short-circuited to voltage
Damaged exhaust temperature sensor before the catalytic converter
The mass air flow meter gives an incorrect reading, for example because of charge air leakage

Was Sie tun können

1If you have a diagnostic tool: start the engine, read the sensor value in live data and compare how it changes with engine load
2Use a multimeter to check that the signal wire has no contact with voltage
3Look for loose or corroded connections at the sensor connector
4Check that the sensor wiring is not pinched or chafed
5If the fault remains, have a workshop check the sensor with diagnostic equipment

Symptome, die Sie bemerken können1

Check engine warning lamp lights or behaves abnormally

Was der Fehler beeinflussen kann1

A calculated value is used instead of the sensor signal
