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.
