Check the mass air flow (MAF) sensor connector and terminal. Check for contact resistance and oxidation.
NOTE:
The intake air temperature (IAT) sensor is integrated in the mass air flow (MAF) sensor.

Remedy as necessary.
- If no faults are found and the fault returns as a permanent fault, replace the intake air temperature (IAT) sensor.
