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. Mostfactory ABS wheel speed sensors will be a two-wire Hall Effect type. These are powered sensors that produce a square wave pulsed output unlike a non-powered variable reluctance sensor that will produce a sine wave output. 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 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. 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.
