Acura Rdx ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Acura Rdx

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

Signs of a Failing ABS Wheel Speed Sensor on the Acura Rdx

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

Passive vs. Active ABS Sensors for the Acura Rdx

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

Why GeoBrakes for the Acura Rdx ABS Wheel Speed Sensor

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

Frequently Asked Questions - Acura Rdx ABS Wheel Speed Sensor

Can I drive my Acura Rdx with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Acura Rdx?

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

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

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