Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor/Intake Air Temperature Sensor Replacement

Removal Procedure




1. Disconnect the mass air flow (MAF)/intake air temperature (IAT) sensor electrical connector (3).
2. Remove the MAF/IAT sensor screws (2).

Caution:
* Handle the MAF sensor carefully.
* Do not drop the MAF sensor in order to prevent damage to the MAF sensor.
* Do not damage the screen located on the air inlet end of the MAF.
* Do not touch the sensing elements.
* Do not allow solvents and lubricants to come in contact with the sensing elements.
* Use a small amount of a soap based solution in order to aid in the installation.

3. Carefully remove the MAF/IAT sensor (1) from the air cleaner housing duct.
4. Discard the MAF/IAT sensor gasket.
