How to Service and Repair a Mass Air Flow Sensor on Ford F-150?

The service process for the Mass Air Flow (MAF) sensor begins by disconnecting the battery ground cable together with opening the engine air cleaner. Begin MAF sensor service by unconnecting its wiring harness connector then remove the air cleaner clamp and separate the air cleaner inlet from its outlet point. Avoid handling the MAF sensor elements since this could cause unit failure. Use scissors to cut tape from the extension harness wire loom and pull it from near the grommet within the air cleaner without touching MAF sensor wires. Pull the grommet from the outlet side of the air cleaner before inserting it along the extension harness. The outlet side MAF sensor plate and mass air flow sensor need to be removed so you can disconnect the MAF sensor electrical connector then take out the nuts to divide the MAF plate from the sensor. Before installing the components reverse all steps while making sure the grommet at the extension harness correctly seats within the engine air cleaner housing to avoid engine air intake. The MAF sensor module requires replacement alongside its body as an integrated unit to match the fitment between engine air cleaner inlet and outlet.
