What is a ABS Speed Sensor?

Anti-lock brake systems (ABS) are a mainstay in most modern cars. These brake systems make use of sensors in determining the rotation rates of car wheels. The information is then sent to a computer for proper regulation of brake pressure in the event that the car wheels lock when braking. Considered a Hall effect component, the sensor analyses wave produced by the tone ring that is affixed to the axle or wheel. There are four-channel ABS systems in cars, and each monitors to which they are attached. Older pickups, however, have three-channel systems, with the rear axle monitored by a sensor and the remaining two sensors for the front wheels.

Note:

– The entire brake system will cease to operate with no anti-lock control if one ABS speed sensor fails. Your mechanic will usually be able to identify which, and how many sensors have failed after diagnosing the system.

– The Anti-lock brake system light automatically turns on and stays lit when the car’s ABS sensor fails.

– Losing the functionalities of your ABS system makes steering overly difficult, especially in emergency situations where brakes might be locked up and stopping distance increased.
