• Q: How to Service the Mass Air Flow Sensor on 2005 Ford Excursion?

  A: The first step when servicing the mass air flow (MAF) sensor is to disconnect the battery ground cable. Handling the MAF sensing elements in the airflow meter should be avoided to prevent unit failure. Start by unplugging the MAF sensor wire while performing engine air cleaner maintenance to disconnect the air cleaner clamp and divide the inlet section from the outlet section of the cleaner. After disconnecting the MAF sensor electrical connector the second time remove the nuts which enables separation of the MAF sensor from the MAF sensor plate. It is vital to check that the grommet installed at the engine air cleaner housing extension harness has complete seating to prevent air leaks into the engine. Follow the alignment notch reference to correctly match the inlet and outlet of the engine air cleaner housing. Install the MAF sensor properly by ensuring the wires remain free from trapping behind the sensor while the electrical connector should point upward. The installation should be finished by repeating the steps in the removal process.
