Was bedeutet der Fehlercode?

This fault code concerns the outside temperature sensor in the left mirror, which is compared with the intake air temperature. It is set when the signal from the outside temperature sensor is too high.

Mögliche Ursachen

Contact resistance in the connector
Damaged outside temperature sensor

Was Sie tun können

1Use a multimeter to check that the signal wire from the outside temperature sensor has no voltage with the ignition off
2Check the connector to the outside temperature sensor in the left mirror for contact resistance
3If you have a diagnostic tool: read the outside temperature in live data and see whether it is reasonable compared with the outdoor air
4Have a workshop check the outside temperature sensor if the fault returns

Symptome, die Sie bemerken können1

Check engine lamp (MIL) lights up

Was der Fehler beeinflussen kann1

The lowest intake air temperature value from the mass air flow sensor during the drive cycle is used
