Chevrolet Impala ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Chevrolet Impala

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

Signs of a Failing ABS Wheel Speed Sensor on the Chevrolet Impala

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

Passive vs. Active ABS Sensors for the Chevrolet Impala

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

Why GeoBrakes for the Chevrolet Impala ABS Wheel Speed Sensor

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

Frequently Asked Questions - Chevrolet Impala ABS Wheel Speed Sensor

Can I drive my Chevrolet Impala with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Chevrolet Impala?

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

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

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