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. Disconnect the MAF/IAT sensor electrical connector.
2. Loosen the clamp on the air intake duct at the throttle body.
3. Loosen the clamps on each side of the MAF/IAT sensor.
4. Remove the air intake duct.
5. Remove the MAF/IAT sensor from the air cleaner housing.

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 into the air cleaner housing.
3. Tighten the clamp securing the MAF/IAT sensor to the air cleaner housing.
4. Install the air intake duct to the MAF/IAT sensor and the throttle body.
5. Tighten the clamps at the MAF/IAT sensor and the throttle body.
6. Connect the MAF/IAT sensor electrical connector.
