Intake Air Temperature 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 from the MAF/IAT sensor. Refer to Air Cleaner Resonator Outlet Duct Replacement (See: Fuel Delivery
and Air Induction/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 (1).
3. Loosen the MAF/IAT sensor adapter clamp.
4. Remove the MAF/IAT sensor from the air cleaner assembly.
