Air Flow Meter/Sensor: Service and Repair
REMOVAL1. Disconnect the battery ground cable.
2. Open the air cleaner.
^ Disconnect the MAF sensor extension harness connector from the wiring harness.
^ Release the air cleaner clamp.
^ Separate the inlet side of the air cleaner from the outlet side of the air cleaner.
CAUTION: Do not tamper with the sensing elements located in the Mass Air Flow (MAF) sensor. Tampering may result in unit failure.
NOTE: The MAF sensor module and body are calibrated and serviced 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 air cleaner.
4. Remove the grommet from the outlet side of the air cleaner and slide the grommet down the extension harness.
5. Remove the MAF sensor plate and the MAF sensor from the outlet side of the air cleaner.
6. Disconnect the MAF sensor electrical connector from the extension harness.
7. Separate the MAF sensor plate from the MAF sensor
^ Remove the nuts from the MAF sensor plate.
INSTALLATION
1. To install, reverse the removal procedure.
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 correctly align the inlet side and the outlet side of the air cleaner.
