2003 Cadillac Escalade Parts Questions & Experts Answers

• Q: How to replace the Mass Air Flow Sensor and Intake Air Temperature Sensor on 2003 Cadillac Escalade?

  A: When replacing the mass air flow (MAF) and intake air temperature (IAT) sensor handle the device carefully to keep the air inlet honeycell intact while also avoiding physical contact with the sensing elements and cleaning solutions or lubricants. Some non-silicone based lubricant can be used to aid installation. A minimal amount of non-silicone lubricant is acceptable for applying on the air duct to help with the installation process. Start by removing first the air cleaner outlet duct followed by pulling out the gray connector position assurance (CPA) retainer. The sensor electrical connection requires disconnecting through black clip pressure while loosening the clamp and sliding out the sensor from the air flow assembly. It is essential to put the new maf/iat sensor into position with the embossed arrow facing the engine direction. Perform installation of the sensor to the air cleaner assembly followed by clamp tightening to 7 n.m (62 lb in) and electrical connector reattachment before inserting the gray cpa retainer and reinstalling the air cleaner outlet duct.
