Toyota Prius ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Toyota Prius

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

Signs of a Failing ABS Wheel Speed Sensor on the Toyota Prius

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

Passive vs. Active ABS Sensors for the Toyota Prius

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

Why GeoBrakes for the Toyota Prius ABS Wheel Speed Sensor

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

Frequently Asked Questions - Toyota Prius ABS Wheel Speed Sensor

Can I drive my Toyota Prius with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Toyota Prius?

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

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

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