Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor with Intake Air Temperature Sensor Replacement

Removal Procedure

Note: Use care when handling the mass air flow (MAF)/intake air temperature (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

Note: 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.

Caution: Refer to Fastener Caution (Fastener Caution).

3. Tighten the clamp securing the MAF/IAT sensor to the air cleaner housing. Tighten the clamp to 7 Nm (62 in. lbs.).
4. Install the air cleaner outlet duct.
5. Install the air cleaner outlet duct bolt and tighten to10 Nm (89 in. lbs.).
6. Tighten the clamps at the MAF/IAT sensor and the throttle body to7 Nm (62 in. lbs.).




7. Connect the MAF/IAT electrical connector.
