ABS Speed Sensor Set
The ABS Speed Sensor Set is a component of your vehicle's Anti-lock Braking System (ABS). It is used to monitor the speed and traction of an automobile's wheels. The ABS speed sensor is fitted to the wheel hub. It consists of a permanent magnet enclosed by a coil, and a toothed sensor ring that is attached around the constant-velocity (CV) joint hub. When the tooth comes under the sensor, the magnetic field changes, generating a single-direction current in the coil. After the tooth passes, the magnetic field returns to normal, producing a current in the opposite direction. This process generates an AC signal which is converted to a digital signal.
This digital signal is processed by the ABS control module which evaluates the wheel speed by counting the number of pulses. It compares the wheel speeds received from each of the four wheels. If the control module detects a difference in the speed of a wheel from other wheels, it takes necessary action to prevent the wheel from losing traction.
A faulty ABS speed sensor will cause your whole anti-lock braking system to fail. One of the visible indications of a bad ABS sensor is the lighting up of the ABS warning light in your car's dashboard. If your vehicle lacks noticeable traction control, it may be a symptom of a damaged ABS sensor. A faulty ABS sensor needs to be replaced at the earliest.
