Air Flow Meter/Sensor: Service and Repair
Mass Airflow Sensor/Intake Air Temperature Sensor Replacement
Removal Procedure
Important: Take 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. Do not
drop or roughly handle the MAF/IAT sensor.
1. Remove air intake resonator. 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 MAF/IAT sensor electrical connector.
3. Loosen the clamp securing the MAF/IAT sensor to the air cleaner housing.
4. Remove the MAF/IAT sensor from the air cleaner assembly.
Installation Procedure
Important:: The embossed arrow on the MAF/IAT sensor indicates the proper air flow direction. The arrow must point toward the engine.
1. Locate the air flow direction arrow (2) on the MAF/IAT sensor.
2. Install the MAF/IAT sensor on to the air cleaner housing.
3. Tighten the clamp securing the MAF/IAT sensor to the air cleaner housing.
4. Connect the MAF/IAT electrical connector.
5. Install air intake resonator. 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) .
