• An essential part of your anti-lock braking system
• A malfunctioning ABS sensor might trigger a dashboard light
• Can be clogged or damaged by brake dust and road debris

The ABS Wheel Speed Sensor (Rear) is a sensor located on the rear wheels of your INFINITI. The ABS Wheel Speed Sensor (Rear) analyzes wheel speed and sends the data directly to your ABS (anti-lock braking system). Using that information, the ABS computer keeps the brakes on your INFINITI from seizing and locking up in the case of extreme braking.

Without a functioning ABS system and sensors your INFINITI's brakes might seize, causing some wheels to stop turning and others to continue spinning. If the brakes lock up when it's time to brake, you could lose control of your INFINITI. Once the ABS Wheel Speed Sensor (Rear) senses the wheels are turning at various intervals, the ABS will adjust the brakes until your wheels are spinning properly.

If your ABS Wheel Speed Sensor (Rear) stops working properly, it may no longer send the correct data or stop communicating altogether to the anti-lock braking system, and it may not be able to properly regulate the brakes when you need them most. A poorly functioning wheel sensor might also illuminate your ABS light or the Malfunction Indicator Light on your INFINITI dashboard.

Typical issues with the ABS Wheel Speed Sensor (Rear) can occur when debris like dirt and brake dust get into the wheel speed sensor or when exposed to hard objects or incidents. If the sensor has been damaged or is malfunctioning, get it replaced with a genuine replacement ABS Wheel Speed Sensor (Rear) from INFINITI Parts to guarantee a proper fit.
