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, 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.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 RB1RD.
