Air Flow Meter/Sensor: Service and Repair

MASS AIR FLOW (MAF)/INTAKE AIR TEMPERATURE (IAT) SENSOR REPLACEMENT

REMOVAL PROCEDURE

IMPORTANT: Use care when handling the mass air flow/intake air temperature (MAF/IAT) sensor. Do not dent, puncture, or otherwise damage the honeycell 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.
