Air Temperature Sensor ( Ambient / Intake ): 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. Remove the air cleaner outlet resonator. Refer to Air Cleaner Resonator Outlet Duct Replacement (Service and Repair).
2. Disconnect the engine wiring harness electrical connector (2) from the MAF/IAT sensor.




3. Loosen the MAF/IAT sensor adapter clamp.
4. Remove the MAF/IAT sensor from the air cleaner assembly.

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 to the air cleaner assembly.

Caution: Refer to Fastener Caution (Fastener Caution).

2. Tighten the MAF/IAT sensor adapter clamp.

Tighten the clamp to 4 Nm (35 lb in).




3. Connect the engine wiring harness electrical connector (2) to the MAF/IAT sensor.
4. Install the air cleaner outlet resonator. Refer to Air Cleaner Resonator Outlet Duct Replacement (Service and Repair).
