Air Flow Meter/Sensor: Service and Repair

REMOVAL PROCEDURE




1. Loosen the clamps on the air duct (1) from the air cleaner.
2. Disconnect the wiring harness from the Mass Air Flow/Intake Air Temperature (MAF/IAT) sensor (3).
3. Loosen the hose clamps (2) at the bottom and top of the MAF/IAT sensor.
4. Remove the air duct (1) from the air cleaner to the MAF/IAT sensor.

IMPORTANT: Do not disassemble the MAF sensor. Remove and install as a complete unit only. If there is external deformation, e.g., deformation of grid, replace the MAF sensor.

5. Remove the MAF/IAT sensor from the intake duct. Note the installation position.

INSTALLATION PROCEDURE




1. Install the MAF/IAT sensor (1) into the lower air intake duct. An arrow on the MAF/IAT sensor shows the proper flow direction.
2. Install the air intake duct onto the MAF/IAT sensor and to the air cleaner housing.

NOTE: Refer to Fastener Notice in Service Precautions.

IMPORTANT:Ensure that all of the hose connections are in good condition and are correctly seated.

3. Install all of the hose clamps to the air intake ducts.

Tighten
Tighten the hose clamps to 3 N.m (27 lb in).

4. Connect the wiring harness to the MAF/IAT sensor assembly.
5. Inspect for leaks.
