Buick Allure ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Buick Allure

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

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

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

Passive vs. Active ABS Sensors for the Buick Allure

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

Why GeoBrakes for the Buick Allure ABS Wheel Speed Sensor

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

Frequently Asked Questions - Buick Allure ABS Wheel Speed Sensor

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

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

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

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

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

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