How to service the Mass Air Flow Sensor on Ford Expedition?

The service procedure for Mass Air Flow (MAF) sensor starts by disconnecting the battery ground cable and opening the air cleaner. Service of the MAF sensor begins by disconnecting wires from the harness then freeing the clamp before splitting the air cleaner into intake and outtake compartments. Modifying the sensing elements of the MAF sensor will result in unit failure and requires service to both the MAF sensor module and body as an integral unit. The wire loom's extension harness tape must be cut to reveal its area near the grommet found on the air cleaner. First detach the outlet grommet of the air cleaner and insert it toward the extension harness. Detach the MAF sensor plate and MAF sensor which are located at the outlet side of the air cleaner before disconnecting the MAF sensor electrical connector from the harness extension and completing the removal of the MAF sensor plate by removing its nuts. Reverse the previous steps for installation while confirming that the grommet at the extension harness properly seals against engine air cleaner housing entry of unmetered air. The air cleaner needs alignment through the built-in notch on the device.
