    Q:
    How to troubleshoot the Mass Air Flow Sensor on the Ford Explorer Sport Trac? Posted by Customer
    A:
    Before you blame the sensor for driveability problems, check for wiring issues when troubleshooting the MAF sensor. A hot-wire element is used by the MAF sensor to measure air mass and then it converts it into a voltage signal for the PCM. Faulty MAF sensors can make a car surge or stall in its tracks. To evaluate, measure the voltage from B+ to ground terminal which would be above 10 volts. Consider checking the signal and ground terminals for voltage at idle as well as increased rpm. Apply an ohmmeter to verify broken circuitry in between. Verify that your voltage readings are correct before going any further with your investigation into the wiring harness. In removing the air intake duct, disconnecting the connector, and replacing assembly without separating plastic body from metal ducts is how to replace MAF sensors.
