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

We expect our car windows to seamlessly slide up and down with the touch of a button. So when they don’t operate as they should, we need to understand exactly why. Is it a simple fix or a substantial failure?

In this video from the experts at Delphi, we show you how to calibrate the front windows of a 2015 BMW X5 following a reported fault with the ‘one touch’ feature.

With step-by-step troubleshooting instructions you’ll learn how to quickly pinpoint the problem and fix the issue. The video covers:

• Diagnosing the fault
• Self-calibration and calibration using a diagnostic tool
• Clearing fault codes
• The equipment you need


What can cause car window failure?

It could be anything from the battery having been disconnected and reconnected, the door itself or the door module having been replaced, a blown fuse, or switch failure. That’s why it’s important to run a diagnostic test on the car.

Do I need a diagnostic tool to calibrate a window?

That depends on the make and model. If you don’t have a diagnostic device to hand, try taking the window up and down several times in succession, holding the switch for a few seconds at each end of the travel . This will carry out a self-calibration on the window, but as mentioned, this method depends on the vehicle.

Does it take a long time to run a diagnostic test?

No. With the right diagnostic tool you can have an idea what’s wrong in a few minutes.
