Scion Tc ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Scion Tc

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

Signs of a Failing ABS Wheel Speed Sensor on the Scion Tc

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

Passive vs. Active ABS Sensors for the Scion Tc

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

Why GeoBrakes for the Scion Tc ABS Wheel Speed Sensor

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

Frequently Asked Questions - Scion Tc ABS Wheel Speed Sensor

Can I drive my Scion Tc with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Scion Tc?

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

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

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