GeoBrakes stocks a complete range of passive and active ABS wheel speed sensors confirmed to fit the Porsche 911, each sourced to OEM specifications for direct-fit installation and reliable ABS performance on your 911. Every Porsche 911 sensor is compatible with traction control and stability control systems.
Your Porsche 911 ABS wheel speed sensor is the component that makes anti-lock braking possible on your 911. It monitors the rotational speed of each wheel in real time and sends that data to the Porsche 911 ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your 911, 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 Porsche 911 wheel speed data is reaching the module.
The ABS wheel speed sensor on the Porsche 911 is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your 911. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the 911 ABS module interprets as wheel speed. On most modern Porsche 911 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 911 systems simultaneously.
GeoBrakes stocks both passive and active ABS wheel speed sensors for the Porsche 911. Passive sensors use an analog signal and are found on older 911 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 Porsche 911 vehicles manufactured after the mid-2000s and are required for full compatibility with modern 911 traction and stability control systems.
Signal accuracy matters as much as fitment with Porsche 911 wheel speed sensors. A sensor that generates the correct frequency for your 911 ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Porsche 911. Every sensor in the GeoBrakes catalogue is matched to the Porsche 911 through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your 911.
Can I drive my Porsche 911 with a faulty ABS wheel speed sensor?
You can drive the Porsche 911 with a failed ABS sensor, but the anti-lock braking system on your 911 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 Porsche 911. Replacing a failed sensor promptly is strongly recommended, particularly before winter.
How do I find the right ABS sensor for my Porsche 911?
Use the GeoBrakes vehicle selector and enter the Porsche 911 year, make, and model. The system displays only the sensors confirmed to fit the Porsche 911, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your 911 to avoid receiving the wrong unit.
Do I need to replace all four ABS sensors on my Porsche 911 at the same time?
No. ABS wheel speed sensors on the Porsche 911 are independent components and only the failed unit needs to be replaced. However, if your 911 has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Porsche 911 sensors for corrosion while the wheel is removed.
