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 low.
Mögliche Ursachen
- Contact resistance in the connector
- Damaged outside temperature sensor
Was Sie tun können
- 1Check the connector to the outside temperature sensor in the left mirror
- 2Look for damage or moisture in the connector at the sensor
- 3If you have a diagnostic tool: read the outside temperature in live data and compare it with an ordinary thermometer outdoors
- 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
