Hyundai Sonata ABS Wheel Speed Sensor in US

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

What Is the ABS Wheel Speed Sensor on Your Hyundai Sonata

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

Signs of a Failing ABS Wheel Speed Sensor on the Hyundai Sonata

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

Passive vs. Active ABS Sensors for the Hyundai Sonata

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

Why GeoBrakes for the Hyundai Sonata ABS Wheel Speed Sensor

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

Frequently Asked Questions - Hyundai Sonata ABS Wheel Speed Sensor

Can I drive my Hyundai Sonata with a faulty ABS wheel speed sensor?

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

How do I find the right ABS sensor for my Hyundai Sonata?

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

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

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