How Does an ABS Speed Sensor Work?
Antilock Braking Systems Anti-lock braking systems (ABS) are common on newer model cars. ABS controls the braking ability of the car under select driving conditions that result in a loss of traction. This system features a controller, valves, and speed sensor that work in conjunction to determine the safe braking ability of your car. ABS speed sensors monitor the rotation of each tire, making sure that each wheel is rotating properly. Any slippage or difference between the wheels triggers the ABS system. Parts of the ABS ABS begins with sensors deciding if the wheels are losing traction. Once this decision is made, the controller (like a computer) engages a valve system in the vehicle that controls available brake fluids in the lines. Since brakes work based on pressure generated by fluid compressed in the brake lines, a pump engages in the braking system to rapidly apply the brakes. This application occurs faster than any human can apply the brakes. Many drivers feel a pulsing feeling
