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 engine wiring harness electrical connector (1) from the MAF/IAT sensor.




2. Remove the MAF/IAT sensor screws (1).
3. Remove the MAF/IAT sensor (2) from the air cleaner upper 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. Install the MAF/IAT sensor (2) to the air cleaner upper housing.

Caution: Refer to Fastener Caution (Fastener Caution).

2. Install the MAF/IAT sensor screws (1).

Tighten the screws to 1.5 Nm (13 lb in).




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