Mass Airflow Sensor: Notes

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. 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.
