• Q: How to replace the Mass Air Flow Sensor on 2003 Cadillac DeVille?

  A: The maf / iat sensor replacement begins by disconnecting its electrical connection followed by removing clamps securing the maf/iat sensor assembly between the air cleaner and the intake air duct. Handle the maf/iat sensor with care while extracting it from the air cleaner and intake air duct by avoiding both dropping it and touching sensing elements or damaging the screen at the air inlet end. Install the sensor by wetting its elements with a touch of soap solution while keeping all liquids away from the sensing elements. Place the maf/iat sensor back into the air cleaner and intake air duct by following the same installation precautions step-by-step. Secure the maf/iat sensor assembly within the air cleaner and intake air duct using clamps while tightening them to 3 n.m (27 lb in). Hook up the electrical connector to the maf/iat sensor as the final step.
