Air Flow Meter/Sensor: Service and Repair

MASS AIR FLOW (MAF) / INTAKE AIR TEMPERATURE (IAT) SENSOR REPLACEMENT







REMOVAL PROCEDURE
1. Disconnect the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector (1).
2. Remove the clamps securing the MAF/IAT sensor assembly to the air cleaner and intake air duct.
3. Carefully remove the MAF/IAT sensor from the air cleaner and intake air duct.

NOTE:
- 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.








INSTALLATION PROCEDURE
1. Carefully install the MAF/IAT sensor (1) into the air cleaner and intake air duct.

NOTE:
- Handle the MAF sensor carefully.
- Do not drop the MAF sensor in order to prevent damage to the MAF sensor.
