ABS Sensor FAQs

How to replace an ABS sensor?

The sensor sits close to the wheel hub. Replacing it usually means unclipping the old one, unbolting it from its bracket, and plugging in a new one. It’s not the hardest job but because it’s part of your braking system, many people prefer to let a professional fit it.

How to test ABS sensor?

If your ABS light has come on, that’s the first sign something’s up. The best way to check the sensor properly is with a diagnostic tool that can read the car’s error codes. A mechanic might also use a multimeter to see if the sensor is sending the right signal.

When are anti-lock brakes ABS most effective?

ABS helps the most when you need to brake hard on a slippery or wet road. Instead of the wheels locking up, the system keeps them turning just enough so that you can still steer while slowing down quickly.
