Subaru Crosstrek ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Subaru Crosstrek

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

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

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

Passive vs. Active ABS Sensors for the Subaru Crosstrek

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

Why GeoBrakes for the Subaru Crosstrek ABS Wheel Speed Sensor

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

Frequently Asked Questions - Subaru Crosstrek ABS Wheel Speed Sensor

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

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

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

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

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

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