The intake air temperature (IAT) sensor is an integral part of the mass air flow (MAF) sensor and cannot be serviced separately. Replacement of the MAF sensor is required in order to replace the IAT sensor.

1. Disconnect the electrical connector (1) from the mass air flow (MAF) sensor (4).
2. Remove the two fasteners.
3. Remove the MAF sensor (4) from the air cleaner housing (2).
4. Remove the O-ring (3).

1. Install a new O-ring (3) on the MAF sensor.
2. Install the MAF sensor (4) into the air cleaner housing (2).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Secure the MAF sensor to the air cleaner housing with the 2 fasteners.

Tighten
Tighten the 2 fasteners to 2 N·m (18 lb in).

4. Connect the MAF sensor electrical connector (1).
