Checking The Connector

HINT: The intake air temperature (IAT) sensor is integrated in the boost pressure sensor. 

• Check the boost pressure sensor connector and terminals. Check for contact resistance and oxidation.

  If the diagnostic trouble code (DTC) for this fault returns after erasing diagnostic trouble codes (DTCs) and test driving, trying using a new boost pressure sensor.

  Remedy as necessary.
