Air Flow Meter/Sensor: Service and Repair
Mass Airflow Sensor with Intake Air Temperature Sensor Replacement
Removal Procedure
Note
Use care when handling the mass air flow (MAF)/intake air temperature (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.
1. Remove the air cleaner outlet resonator. Refer to Air Cleaner Resonator Outlet Duct Replacement (See: Air Cleaner Housing/Air Cleaner Fresh
Air Duct/Hose/Service and Repair) .
2. Disconnect the engine wiring harness electrical connector (2) from the MAF/IAT sensor.
