Cadillac Deville ABS Wheel Speed Sensor in US

Your Cadillac Deville ABS wheel speed sensor is the component that makes anti-lock braking possible on your Deville. It monitors the rotational speed of each wheel in real time and sends that data to the Cadillac Deville ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your Deville, your ABS loses the input it needs. On wet, icy, or gravel road surfaces, the difference between a controlled stop and a skid can come down to whether your Cadillac Deville wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Cadillac Deville

The ABS wheel speed sensor on the Cadillac Deville is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your Deville. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the Deville ABS module interprets as wheel speed. On most modern Cadillac Deville vehicles, this same data feeds the traction control system, electronic stability control, and electronic brake force distribution, making a functioning wheel speed sensor critical to the safe operation of multiple Deville systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Cadillac Deville

• ABS warning light on your Cadillac Deville dashboard, the most common first indicator of a failing sensor
• Traction control or stability control warning light illuminated alongside the Deville ABS light
• ABS activating on your Cadillac Deville during normal stops at low speed where it should not engage
• Complete ABS deactivation on the Deville, wheels lock under hard braking on wet or icy roads
• Speedometer on your Cadillac Deville reading erratically or dropping to zero at speed
• Fault codes in the C0035 to C0050 range stored in the Cadillac Deville ABS control module

Passive vs. Active ABS Sensors for the Cadillac Deville

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Cadillac Deville. Passive sensors use an analog signal and are found on older Deville vehicles and many trucks still in service. Active Hall-effect sensors require a small power supply and output a clean digital signal, offering greater accuracy at very low speeds. Active sensors are standard on most Cadillac Deville vehicles manufactured after the mid-2000s and are required for full compatibility with modern Deville traction and stability control systems.

Why GeoBrakes for the Cadillac Deville ABS Wheel Speed Sensor

Signal accuracy matters as much as fitment with Cadillac Deville wheel speed sensors. A sensor that generates the correct frequency for your Deville ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Cadillac Deville. Every sensor in the GeoBrakes catalogue is matched to the Cadillac Deville through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your Deville.

Frequently Asked Questions - Cadillac Deville ABS Wheel Speed Sensor

Can I drive my Cadillac Deville with a faulty ABS wheel speed sensor?

You can drive the Cadillac Deville with a failed ABS sensor, but the anti-lock braking system on your Deville will be completely disabled. On icy or wet American roads, this significantly increases stopping distances and the risk of losing steering control during hard braking on your Cadillac Deville. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Cadillac Deville?

Use the GeoBrakes vehicle selector and enter the Cadillac Deville year, make, and model. The system displays only the sensors confirmed to fit the Cadillac Deville, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your Deville to avoid receiving the wrong unit.

Do I need to replace all four ABS sensors on my Cadillac Deville at the same time?

No. ABS wheel speed sensors on the Cadillac Deville are independent components and only the failed unit needs to be replaced. However, if your Deville has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Cadillac Deville sensors for corrosion while the wheel is removed.
