Likeany other speed sensor, a speed sensor can be an inductive sensor (magnet with a wire coil surrounding it) that produces an AC analog wave, or it can be digital, which produces a square wave. Some wheel speed sensors are designed to detect whether the vehicle is moving forward or backward.
Thetwo most important things to know about wheel speed sensors are: 1. What kind of sensor to use 2. Where they can be located. The most common place to find a factory vehicle speed sensor is on the gearbox where you'd usually find a sensor detecting the speed of the output shaft which is directly related to road speed.
Awheel speed sensor (WSS) or vehicle speed sensor (VSS) is a type of tachometer. It is a sender device used for reading the speed of a vehicle's wheel rotation . It usually consists of a toothed ring and pickup.
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
Themerging and processing of the individual wheel speed sensor signals by the control unit provide a single reference speed which is roughly the vehicle speed. A comparison of any individual wheel speed with the reference speed supplies the wheel to road slip (wheel tending to lock) signal.
Thepassive speed sensor creates its own AC signal that changes frequency with wheel speed. This signal is only present while the wheel is turning at a rate fast enough to create the AC signal. Vehicles equipped with passive wheel speed sensors do not read at or below 2 mph coming from a dead stop. During a wheel-spin condition, or under a
Thewheel speed sensor is responsible for relaying the wheel speed to the ECU so that it can tell the ABS system how much pressure to safely apply. When the wheel speed sensor is broken or not working as it should, one of the first things that are affected is the ABS system.
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.
Thereare two types of wheel speed sensors: one that uses magnetoresistive principles, and one that uses a magnetic pulse sensor (encoder wheel). A digital output signal is sent to the ABS using active wheel speed sensors, which operate at temperatures between -40°C and +150°C.
