Mass Air Flow/Intake Air Temperature Sensor: Notes

WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Take care when handling the Mass Airflow/Intake Air Temperature (MAF/IAT) sensor. Do not dent, puncture, or otherwise damage the honey-cell located at the air inlet end of the MAF/IAT. Do not touch the sensing elements or allow anything including cleaning solvents and lubricants to come in contact with them. Use a small amount of a non-silicone based lubricant, on the air duct only, to aid in installation. Do not drop or roughly handle the MAF/IAT sensor. The embossed arrow on the MAF/IAT sensor indicates the proper air flow direction. The arrow must point toward the engine.
