2003 Ford Excursion Mass Air Flow Sensor Parts Questions & Experts Answers

• Q: How to Service and Repair the Mass Air Flow Sensor on 2003 Ford Excursion?

  A: Service and repair of the Air Flow Meter/Sensor starts with disconnecting the battery ground cable while opening the engine air cleaner. Unplug the MAF sensor electrical connector then release the air cleaner clamp before splitting apart the air cleaner between its inlet and outlet sections. Touching the Mass Air Flow (MAF) sensor elements in the airflow meter will result in unit failure. The MAF sensor and body should be repaired in a combined form. You must disconnect the MAF sensor electrical connector for a second time before unfastening the nuts to take the MAF sensor off the MAF sensor plate. The installation requires reversing all removal steps while making sure the engine air cleaner housing grommet is completely seated at the extension harness to stop unmetered air from entering the engine. Align the inlet and outlet parts of the engine air cleaner by using the displayed alignment notch before installing the MAF sensor while making sure wires stay clear from trapping behind it and always position the electrical connector upward.
