Anti-lock Brake System (ABS) Sensors

Technology such as anti-lock brakes (ABS) and electronic stability are now common place thanks to the ABS sensor or wheel speed sensor. A small device, it has a big role to play; monitoring the wheel’s speed and rotation to prevent the brakes from locking. So, it’s important to always fit an OE quality part - anything less could compromise the effectiveness of these safety critical systems. Featuring weather pack connectors and plated pins, and rigorously tested to OE standards, Delphi ABS sensors deliver optimum signal stability and reliability in all conditions, for an accurate, long-lasting sensor that you can fit with confidence.

Latest OE technology

Our ever-expanding range of ABS sensors features the latest digital signal technology. By creating a digital, square wave, Delphi magneto resistive and hall effect sensors only change frequency, not amplitude, improving accuracy, especially at lower speeds. They can also detect the direction of the wheels; forward, reverse and even stop. This is vital for hill hold control, autohold and automatic parking assistance technologies.

Protection from the elements

Given its position, the ABS sensor is particularly vulnerable to contamination from dirt and moisture. That’s why Delphi ABS sensors feature weather-pack connectors that lock out dirt, moisture, chemicals and other contaminants, coupled with plated pins for even great corrosion protection and improved conductivity.

Extreme testing

Water, heat and vibration can all affect a sensors characteristic. So we subject all our sensors to extensive thermal, shock and vibration testing just to be sure. With test temperatures ranging from -40 o C to 140 o C, we know they’ll perform even in the most challenging conditions. Delivering optimum stability and reliability at all times.

Easy installation

For right-fist-time fitment, Delphi ABS sensors are designed to match the OE. With like-for-like mounting and connector designs and wire lengths, technicians can fit quickly and easily, straight from the box.

The complete solution

As well as a growing range of ABS sensors, we also offer advanced diagnostic capability including the ability to read live fault codes and individual wheel speed data, essential repair data through our vehicle technical information package, and expert training and technical support.

Resource Highlights

Exposed to heat, dirt and moisture, ABS sensors can often need replacing. Learn how here.

How do I remove the existing ABS sensor?

First, remove the wheel. Then, remove the clip on the arch liner to give access to the connector on the ABS sensor. Now, disconnect the faulty ABS sensor followed by the mounting rubbers. Next, pivot the hub so it’s easier to get to the 10mm securing bolt holding the ABS sensor in place. Remove the bolt, free the sensor from its mounting and remove it.

Do I need to do a visual check of the new part?

We always recommend checking the new part against the old one to make sure that it matches. It’s quick to do and ensures you’re fitting a like-for-like new part. To do this, hold the old and new ABS sensors next to each other. Now check that their heads are identical, also that the electrical connectors have the same pins and locating point.

In what order do I fit the new component?

Start by fitting the electrical connector. Next, secure the cable to the chassis using the clips. You now need to clean the hub for a flush fit. Once you’ve done this, fit the ABS sensor in place. Now, replace the 10mm bolt before resecuring the arch liner. Finally, refit the wheel.
