Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor/Intake Air Temperature Sensor Replacement

Removal 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.






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




2. Loosen the air cleaner outlet duct clamp at the throttle body.




3. Loosen the air cleaner outlet duct clamp at the MAF/IAT sensor.
4. Remove the air cleaner outlet duct.




5. Remove the MAF/IAT sensor bolts.
6. Remove the MAF/IAT sensor.


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.






1. Install the MAF/IAT sensor.

Notice: Refer to Fastener Notice (Fastener Notice).

2. Install the MAF/IAT sensor bolts.

Tighten the bolts to 4 N.m (35 lb in).




3. Install the air cleaner outlet duct.
4. Tighten the air cleaner outlet duct clamp at the MAF/IAT sensor.

Tighten the clamp to 4 N.m (35 lb in).




5. Tighten the air cleaner outlet duct clamp at the throttle body.

Tighten the clamp to 4 N.m (35 lb in).




6. Connect the engine harness electrical connector to the MAF/IAT sensor.
