2001 Cadillac Catera Parts Questions & Experts Answers

• Q: How to replace the Mass Air Flow Sensor on 2001 Cadillac Catera?

  A: The replacement process of mass air flow (MAF) / intake air temperature (IAT) sensor starts with loosening clamps on the air duct that leads from the air cleaner then disconnecting the wiring harness from the maf/iat sensor. You must disconnect the air duct from the air cleaner to the maf/iat sensor by loosening its hose clamps first. Thorough maf sensor disassembly is strictly prohibited for this step. The complete maf/iat sensor unit should be removed before installation. The maf sensor needs replacement when external deformations including grid deformations appear. Mark down where to install the maf/iat sensor before extracting it out of the intake duct. The maf/iat sensor installation requires insertion into the lower air intake duct with the sensor arrow pointed toward the correct flow path. Fasten the maf/iat sensor and air cleaner housing together through the air intake duct while ensuring tight secure hose connections. All air intake duct hose clamps should be installed and tightened to 3 n.m (27 lb in). Inspection for leaks should be performed after connecting the wiring harness to the maf/iat sensor assembly.
