Removal Procedure

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

Installation Procedure

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.

Insert the MAF/IAT sensor into the air cleaner assembly.
