Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor with Intake Air Temperature Sensor Replacement

Removal Procedure

1. Remove the radiator and air baffle. Refer to Radiator Air Upper Baffle and Deflector Replacement (Service and Repair) .




2. Disconnect the mass air flow (MAF)/air intake temperature (IAT) wiring harness connector (2) to mass air flow (MAF)/air intake temperature (IAT) sensor (1).




3. Loosen the air intake duct to MAF/IAT sensor retaining clamp (2).
4. Loosen the upper air cleaner body to MAF/IAT sensor retaining clamp (1).
5. Remove the air intake duct from the mass air flow MAF/IAT sensor.
6. Remove the MAF/IAT sensor (3) from the upper air cleaner body.



Installation Procedure






Important: Make sure that the arrow on the MAF/IAT sensor is pointing to the front, radiator, indicate the proper air flow direction. The arrow must point toward the engine.


1. Install the MAF/IAT sensor to the upper air cleaner body.
2. Install the air intake duct to the MAF/IAT sensor.
3. Position the retaining clamps (1 and 2) to the MAF/IAT sensor.

Notice: Refer to Fastener Notice (Fastener Notice) .

4. Tighten the MAF/IAT retaining clamps (1 and 2).

Tighten the clamps to 4 N.m (35 lb in).





5. Connect the MAF/IAT wiring harness connector (2) to the MAF/IAT sensor.
6. If re-programming is required. Refer to Control Module References (Programming and Relearning) .
7. Install the radiator and air baffle. Refer to Radiator Air Upper Baffle and Deflector Replacement (Service and Repair) .
