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 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. Asyou drive, a wheel speed sensor record the speed of its respective wheel'and sends the data to the ABS module. Four-wheel ABS always has a sensor for each wheel typically installed directly on the wheel axle or behind the wheel's brake rotor. Temperaturesensing; Hall Effect Sensors: Bicycle wheels; Gear-teeth; Speedometers; Automotive ignition systems; Generally speaking, vehicle speed sensors can also use other methods to determine wheel speed, such as optical sensors. This makes them suitable for different applications as well; bringing with them their own advantages and Typesof Wheel Speed Sensors. Vehicles commonly use two-wheel speed sensors: Magnetic inductive sensor. Hall effect sensor. The magnetic inductive sensor relies on a toothed wheel or a tone ring with magnetic properties. In contrast, the Hall effect sensor uses a magnet and a semiconductor to detect wheel speed. 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. Thesensor is mounted at a specific gap from a toothed reluctor ring. As the teeth pass by the wheel speed sensor, it changes the magnetic field and produces alternating current or AC voltage. The AC voltage can be seen by a scope as a sine wave. The voltage signal will increase in amplitude with an increase in the speed of the reluctor ring. 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.
