Lexus Gs450h ABS Wheel Speed Sensor in US

Your Lexus Gs450h ABS wheel speed sensor is the component that makes anti-lock braking possible on your Gs450h. It monitors the rotational speed of each wheel in real time and sends that data to the Lexus Gs450h ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your Gs450h, 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 Lexus Gs450h wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Lexus Gs450h

The ABS wheel speed sensor on the Lexus Gs450h is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your Gs450h. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the Gs450h ABS module interprets as wheel speed. On most modern Lexus Gs450h 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 Gs450h systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Lexus Gs450h

• ABS warning light on your Lexus Gs450h dashboard, the most common first indicator of a failing sensor
• Traction control or stability control warning light illuminated alongside the Gs450h ABS light
• ABS activating on your Lexus Gs450h during normal stops at low speed where it should not engage
• Complete ABS deactivation on the Gs450h, wheels lock under hard braking on wet or icy roads
• Speedometer on your Lexus Gs450h reading erratically or dropping to zero at speed
• Fault codes in the C0035 to C0050 range stored in the Lexus Gs450h ABS control module

Passive vs. Active ABS Sensors for the Lexus Gs450h

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Lexus Gs450h. Passive sensors use an analog signal and are found on older Gs450h 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 Lexus Gs450h vehicles manufactured after the mid-2000s and are required for full compatibility with modern Gs450h traction and stability control systems.

Why GeoBrakes for the Lexus Gs450h ABS Wheel Speed Sensor

Signal accuracy matters as much as fitment with Lexus Gs450h wheel speed sensors. A sensor that generates the correct frequency for your Gs450h ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Lexus Gs450h. Every sensor in the GeoBrakes catalogue is matched to the Lexus Gs450h through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your Gs450h.

Frequently Asked Questions - Lexus Gs450h ABS Wheel Speed Sensor

Can I drive my Lexus Gs450h with a faulty ABS wheel speed sensor?

You can drive the Lexus Gs450h with a failed ABS sensor, but the anti-lock braking system on your Gs450h 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 Lexus Gs450h. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Lexus Gs450h?

Use the GeoBrakes vehicle selector and enter the Lexus Gs450h year, make, and model. The system displays only the sensors confirmed to fit the Lexus Gs450h, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your Gs450h to avoid receiving the wrong unit.

Do I need to replace all four ABS sensors on my Lexus Gs450h at the same time?

No. ABS wheel speed sensors on the Lexus Gs450h are independent components and only the failed unit needs to be replaced. However, if your Gs450h has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Lexus Gs450h sensors for corrosion while the wheel is removed.
