Air Flow Meter/Sensor: Service and Repair

REMOVAL

CAUTION: Always disconnect the battery ground cable prior to work on the electronic engine controls or damage to the electronic component may occur.

1. Disconnect the battery ground cable.







2. Open the engine air cleaner.
- Disconnect the MAF sensor extension harness connector from the wiring harness.
- Release the air cleaner clamp.
- Separate the inlet side of the engine Air Cleaner (ACL) from the outlet side of the engine air cleaner.

CAUTION: Do not tamper with the MAF sensing elements located in the airflow bypass. Tampering may result in unit failure.

NOTE: The MAF sensor module and body are calibrated and replaced as a unit.







3. Cut the tape on the wire loom of the extension harness.
- Peel back the wire loom from the extension harness near the grommet in the engine air cleaner.







4. Remove the grommet from the outlet side of the engine air cleaner and slide the grommet down the extension harness.







5. Remove the MAF sensor plate and Mass Air Flow sensor (MAF sensor) from the outlet side of the engine engine air cleaner.







6. Disconnect the MAF sensor electrical connector from the extension harness.







7. Separate the MAF sensor plate from the mass air flow sensor.
- Remove the nuts from the MAF sensor plate.







INSTALLATION

CAUTION: The grommet used to seal the engine air cleaner housing at the extension harness must be fully seated. Failure to do so will result in unmetered air entering the engine.

NOTE: Use the alignment notch to properly align the inlet side and the outlet side of the engine air cleaner.

1. Follow the removal procedure in reverse order.
