How to Service the Mass Air Flow Sensor on 2003 Ford Ranger?

Service of the Air Flow Meter/Sensor starts with battery ground cable disconnect then moving on to disconnecting the Mass Air Flow (MAF) sensor electrical connector. The first step of servicing the Air Flow Meter/Sensor requires removal of the air intake tube from the MAF sensor followed by removing its four bolts. The installation should include the opposite steps of removal without touching MAF sensing elements inside the airflow bypass because damage can result in sensor failure. The MAF sensor module must be calibrated before installation together with its body as a single unit.
