Air Flow Meter/Sensor: Service and Repair

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

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.

Removal Procedure




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




1. Install the MAF/IAT sensor.
2. Install the MAF/IAT sensor bolts.

NOTE: Refer to Fastener Notice.

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.
