Our ABS wheel speed sensors are manufactured by the high quality materials to match or exceed OEM part performance. It includes but not limited to these Features & Benefits:
- Sensor housing is made from high quality reinforced plastic, offering superior resistance to the elements
- OE connectors and terminals made from premium material are used to ensure an accurate, water-tight connection to the engine wire harness
- Grommets and wire clips are included where applicable per Original Equipment specifications to ensure proper mounting and routing within the car chassis
Typically Features for this ABS Sensor
- Plug and Play design for direct replacement and ease of installation
- Sealed wire connections for corrosion resistance
- Shielded wire harness for added protection from the elements and to reduce electrical noise and signal interference
- Hall sensors that detect forward and backward movement for more accurate readings
What is ABS Wheel Speed Sensor
An ABS wheel speed sensor, also known as an anti-lock braking system (ABS) sensor, monitors the rotation speed of a vehicle's wheels and sends that data to the ABS control module:
The ABS control module then uses this information to adjust the braking pressure to prevent the wheels from locking up during hard braking. This helps the driver maintain steering control and avoid skidding, especially in slippery conditions.
The ABS sensor is typically installed at the wheel's hub or brake assembly. It consists of two components:
- Reluctor wheel or tone ring: Located on the axle, this rotates with the wheel.
- Magnetic or hall effect sensor: Sends the data to the ABS control module.
Symptoms of a Failing ABS Wheel Speed Sensor
The Anti-Lock Brake System (ABS) sensor monitors wheel speed. Common failure symptoms include:
- ABS Light On
- Brake Pulsing
- No / Erratic Traction or Stability Control
- No / Erratic ABS Operation
- Braking Without Pedal Contact
Causes of ABS sensor failure
Whilst ABS sensors are a simple and generally robust part, their location on the vehicle makes them subject to harsh conditions and so the following causes are common:
- Physical damage to sensor from road debris
- Sensor out of position (or increased distance from wheel bearing)
- Breaks in wiring
- Internal short circuits
- Heavy contamination
- Corroded, cracked or swollen ABS ring
- ABS ring blocked, damaged, missing teeth or windows
Problems with the ABS ring can be identified using an oscilloscope and analyzing the patterns as follows:
