Buick Regal ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Buick Regal

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

Signs of a Failing ABS Wheel Speed Sensor on the Buick Regal

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

Passive vs. Active ABS Sensors for the Buick Regal

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

Why GeoBrakes for the Buick Regal ABS Wheel Speed Sensor

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

Frequently Asked Questions - Buick Regal ABS Wheel Speed Sensor

Can I drive my Buick Regal with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Buick Regal?

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

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

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