Cadillac Ats ABS Wheel Speed Sensor in US

Your Cadillac Ats ABS wheel speed sensor is the component that makes anti-lock braking possible on your Ats. It monitors the rotational speed of each wheel in real time and sends that data to the Cadillac Ats ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your Ats, 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 Ats wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Cadillac Ats

The ABS wheel speed sensor on the Cadillac Ats is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your Ats. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the Ats ABS module interprets as wheel speed. On most modern Cadillac Ats 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 Ats systems simultaneously.

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

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

Passive vs. Active ABS Sensors for the Cadillac Ats

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Cadillac Ats. Passive sensors use an analog signal and are found on older Ats 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 Ats vehicles manufactured after the mid-2000s and are required for full compatibility with modern Ats traction and stability control systems.

Why GeoBrakes for the Cadillac Ats ABS Wheel Speed Sensor

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

Frequently Asked Questions - Cadillac Ats ABS Wheel Speed Sensor

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

You can drive the Cadillac Ats with a failed ABS sensor, but the anti-lock braking system on your Ats 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 Ats. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

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

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

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

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