Air Flow Meter/Sensor: Service Precautions

CAUTION:
^ Do not tamper with the sensing elements located in the Mass Air Flow (MAF) sensor. Tampering may result in unit failure.
^ 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.
