The ABS sensor is typically located in each wheel hub/rotor on a four channel ABS system. Some rear wheel drive applications have the sensor mounted in the rear differential.

• The anti-lock braking system uses an ABS or wheel sensor to monitor the wheel speed and send this information to the ABS computer
• Generally these sensors will fail as a result of clogging from metallic debris, brake dust or dirt due to exposure to the harsh elements
• A failing sensor can illuminate the MIL or ABS warning lamp, and may cause failure of the anti-lock braking system to operate safely and properly
• BWD ABS Sensors are designed to meet or exceed OE specifications
