Faulty Signal or Signal Missing

Faulty signal or signal missing

Checking components and wiring

Hint: If a diagnostic trouble code (DTC) for the intake air temperature (IAT) sensor is also stored, this code must be fault-traced first.

Check the connector for the outside temperature sensor. Check for contact resistance and oxidation.
Check the resistance of the outside temperature sensor.

Hint: With the ignition on and the outside temperature sensor connector disconnected, the voltage between terminal #2 and ground must be approximately 5 V.

Remedy as necessary.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?
