Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor/Intake Air Temperature Sensor Replacement

Removal Procedure




1. Disconnect the MAF/IAT sensor electrical connector (1).
2. Remove the air cleaner outlet duct assembly.
3. Loosen the MAF/IAT clamp (2).

Notice:
* 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.

Remove the MAF/IAT sensor from the air cleaner outlet duct. Note the position of the MAF/IAT sensor.
