Hva betyr feilkoden?

The code is intermittent, meaning the fault comes and goes rather than being present all the time. The engine control module measures outside temperature with the sensor in the left mirror, and the code is set when the signal is irregular or implausible.

Mulige årsaker

Contact resistance or oxidation in the connectors
The atmospheric pressure sensor is damaged
The outside temperature sensor is damaged

Hva du kan gjøre

1Read the fault status with a diagnostic tool. Fault found means the fault is present now, while No fault found means the fault is intermittent and not active at the moment
2Make sure the fuses are intact. Their location is given in the instruction manual
3With the ignition off, check the sensor connector in the left mirror for contact resistance and oxidation. Loose contacts often give irregular readings
4If you have a diagnostic tool, follow the outside temperature in live data for a while. A value that jumps without reason points to a poor contact or a moving wire
5Have a workshop check the sensor if the fault comes back

Symptomer du kan merke1

The outside temperature gauge shows the wrong value or does not work

Hva feilen kan påvirke1

A calculated value is used
