Air Temperature Sensor ( Ambient / Intake ): Service and Repair
Mass Airflow Sensor with Intake Air Temperature Sensor Replacement
Removal Procedure
Note:
Take 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. Do not drop or roughly handle the MAF/IAT sensor.
1. Disconnect the MAF/IAT sensor electrical connector (1).
2. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement Service and Repair.
3. Loosen the clamp securing the MAF/IAT sensor to the air cleaner duct.
4. Remove the MAF/IAT sensor bolts from the air cleaner assembly.
5. Remove the MAF/IAT from the air cleaner.
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 onto the air cleaner housing.
Caution:
Refer to Fastener Caution Fastener Caution.
3. Install the MAF/IAT sensor retaining bolts and tighten to 11 Nm (97 lb in).
4. Tighten the clamp securing the MAF/IAT sensor to the air cleaner duct.
5. Install the air cleaner assembly. Refer to Air Cleaner Assembly Replacement Service and Repair.
6. Connect the MAF/IAT electrical connector (1).
