  Q: How to service the Mass Air Flow Sensor on Cadillac Catera?

  A: The first step for servicing the maf sensor involves loosening air duct clamps at the air cleaner before disconnecting the wiring harness from mass air flow/intake air temperature (MAF/IAT) sensor . The service process starts with hose clamp loosening at both ends of the maf/iat sensor followed by removing the air duct connecting the air cleaner to the sensor. You should never take apart the maf sensor because doing so could harm it. When working on this unit always treat it as an entire assembly. Replace the maf sensor when external deformations lead to grid deformation. Remove the maf/iat sensor from the intake duct while documenting its initial position. When installing the maf/iat sensor position it into the lower air intake duct where the arrow indicator points to the correct airflow direction. Attach the air intake duct to the maf/iat sensor and the air cleaner housing while confirming all hose connections have good conditions and secure seating points. Secure all hose clamps on air intake ducts by tightening them to 3 n.m (27 lb in). Attach the wiring harness to the maf/iat sensor assembly while also checking for any signs of leakage.
