Toyota Sienna ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Toyota Sienna

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

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

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

Passive vs. Active ABS Sensors for the Toyota Sienna

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

Why GeoBrakes for the Toyota Sienna ABS Wheel Speed Sensor

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

Frequently Asked Questions - Toyota Sienna ABS Wheel Speed Sensor

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

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

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

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

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

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