Air Flow Meter/Sensor: Service and Repair

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

REMOVAL PROCEDURE

IMPORTANT: Use care when handling the mass air flow/intake air temperature (MAF/IAT) sensor. Do not dent, puncture, or otherwise damage the honeycell located at the air inlet end of the MAF/IAT. Do not touch the sensing elements or allow anything including cleaning solvents and lubricants to come in contact with them. Use a small amount of a non-silicone based lubricant, on the air duct only, to aid in installation.




1. Disconnect the MAF/IAT sensor electrical connector.




2. Loosen the clamps at the MAF/IAT sensor and the throttle body.
3. Remove the air cleaner outlet duct bolt.
4. Remove the air cleaner outlet duct.
5. Loosen the clamp attaching the MAF/IAT sensor to the air cleaner housing.
6. Remove the MAF/IAT sensor from the air cleaner housing.

INSTALLATION PROCEDURE

IMPORTANT: The embossed arrow on the MAF/IAT sensor indicates the proper air flow direction. The arrow must point toward the engine.




1. Locate the air flow direction arrow (2) on the MAF/IAT sensor.




2. Install the MAF/IAT sensor on to the air cleaner housing.

NOTE: Refer to Fastener Notice in Service Precautions.

3. Tighten the clamp securing the MAF/IAT sensor to the air cleaner housing.

Tighten the clamp to 7 N.m (62 lb in).

4. Install the air cleaner outlet duct.
5. Install the air cleaner outlet duct bolt.

Tighten the bolt to 10 N.m (89 lb in).

6. Tighten the clamps at the MAF/IAT sensor and the throttle body.

Tighten the clamps to 7 N.m (62 lb in).




7. Connect the MAF/IAT electrical connector.
