Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor with Intake Air Temperature Sensor Replacement

Removal Procedure




1. Disconnect the engine wiring harness electrical connector (1) from the mass air flow (MAF)/intake air temperature (IAT) sensor (2).




2. Remove the MAF/IAT sensor screws (1).
3. Remove the MAF/IAT sensor (2) from the air cleaner assembly.

Installation Procedure

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.
