Thereare two different types of wheel speed sensors, active and passive. Before you can diagnose a suspected faulty wheel speed sensor, you need to have a good understanding of the type of sensor Theyhave two wires: signal and ground. Inside a passive WSS sensor is a permanent magnet core surrounded by copper wire windings. When the teeth on the tone ring rotate past the sensor tip, it changes the magnetic field and induces a current in the sensor windings. The result is a classic sine wave current pattern that changes with wheel speed. TheHall-type wheel speed sensor is made using the principle of Hall effect. The Hall-type wheel speed sensor has also been widely used in automobiles, and has the following characteristics: the output signal voltage amplitude value is not affected by the rotation speed; the frequency response is high; Strong anti-electromagnetic wave interference ability. 1 What type of sensor is a wheel speed sensor? A wheel speed sensor is a type of vehicle sensor that monitors the rotational speed of each wheel. This information is used by systems such as ABS (Anti-lock Braking System), traction control, and vehicle stability to enhance the safety and performance of the vehicle. 2. Thewheel speed sensor, also known as the vehicle speed sensor (VSS), is a SENSOR used to measure the steering of the car wheels. Commonly used wheel speed sensors are: magnetoelectric wheel speed sensors and Hall effect wheel speed sensors. Thevehicle speed sensor, also known as a transmission speed sensor or output shaft speed sensor, plays an active role in your car's transmission and cruise control systems. There are also ABS wheel speed sensors (WSS) on a vehicle's wheel hubs (both on the front axle and rear axle). U115e.
