x2 Jun 30, 2021 · 1) Set the DMM to the diode range. 2) Keep the mosfet on a dry wooden table on its metal tab, with the printed side facing you and leads pointed towards you. 3) With a screwdriver or meter probe, short the gate and drain pins of the mosfet. This will initially keep the internal capacitance of the device completely discharged. It should raise and drop. Dont recall the resistance but its something like 5-10ohms. And you can test it while connected. Get some thin single strand copper wire. place inside the plug on both pins and plug the sensor in. turn the car on and spin the wheel. Again voltage should rise and drop from like 5-12v.Switch your multimeter to the voltage reading. Identify the wheel speed sensor's electrical connector along the wheel's frame. Be careful not to use the pad wear sensor, which can easily confuse you. Once you find the connector, disconnect it from the sensor by removing the safety clasp and pulling it out gently.ACTIVE WHEEL SPEED SENSORS. Active WSS use two wires and look like passive wheel speed sensors. Active WSS are used on most newer vehicles because they are more accurate at lower speeds and can detect 0 mph. Also, active sensors can even detect if the vehicle is moving in reverse. Active WSSs output a digital signal. Diagnosing Antilock Brake Wheel Speed Sensors. When a wheel speed sensor (WSS) fails or there's a problem in the sensor's wiring circuit, it usually disables the ABS system and causes the ABS warning light to come on. Loss of a wheel speed signal is a serious problem because the ABS module needs accurate input from all its sensors to determine ...

Active WSS use two wires and look like passive wheel speed sensors. Active WSS are used on most newer vehicles because they are more accurate at lower speeds and can detect 0 mph. Also, active sensors can even detect if the vehicle is moving in reverse. Active WSSs output a digital signal. To measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below).
