Toyota Avalon ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Toyota Avalon

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

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

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

Passive vs. Active ABS Sensors for the Toyota Avalon

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

Why GeoBrakes for the Toyota Avalon ABS Wheel Speed Sensor

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

Frequently Asked Questions - Toyota Avalon ABS Wheel Speed Sensor

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

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

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

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

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

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