Subaru Impreza ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Subaru Impreza

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

Signs of a Failing ABS Wheel Speed Sensor on the Subaru Impreza

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

Passive vs. Active ABS Sensors for the Subaru Impreza

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

Why GeoBrakes for the Subaru Impreza ABS Wheel Speed Sensor

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

Frequently Asked Questions - Subaru Impreza ABS Wheel Speed Sensor

Can I drive my Subaru Impreza with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Subaru Impreza?

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

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

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