Pontiac G3 Wave ABS Wheel Speed Sensor in US

Your Pontiac G3 Wave ABS wheel speed sensor is the component that makes anti-lock braking possible on your G3 Wave. It monitors the rotational speed of each wheel in real time and sends that data to the Pontiac G3 Wave ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your G3 Wave, 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 Pontiac G3 Wave wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Pontiac G3 Wave

The ABS wheel speed sensor on the Pontiac G3 Wave is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your G3 Wave. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the G3 Wave ABS module interprets as wheel speed. On most modern Pontiac G3 Wave 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 G3 Wave systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Pontiac G3 Wave

• ABS warning light on your Pontiac G3 Wave dashboard, the most common first indicator of a failing sensor
• Traction control or stability control warning light illuminated alongside the G3 Wave ABS light
• ABS activating on your Pontiac G3 Wave during normal stops at low speed where it should not engage
• Complete ABS deactivation on the G3 Wave, wheels lock under hard braking on wet or icy roads
• Speedometer on your Pontiac G3 Wave reading erratically or dropping to zero at speed
• Fault codes in the C0035 to C0050 range stored in the Pontiac G3 Wave ABS control module

Passive vs. Active ABS Sensors for the Pontiac G3 Wave

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Pontiac G3 Wave. Passive sensors use an analog signal and are found on older G3 Wave 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 Pontiac G3 Wave vehicles manufactured after the mid-2000s and are required for full compatibility with modern G3 Wave traction and stability control systems.

Why GeoBrakes for the Pontiac G3 Wave ABS Wheel Speed Sensor

Signal accuracy matters as much as fitment with Pontiac G3 Wave wheel speed sensors. A sensor that generates the correct frequency for your G3 Wave ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Pontiac G3 Wave. Every sensor in the GeoBrakes catalogue is matched to the Pontiac G3 Wave through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your G3 Wave.

Frequently Asked Questions - Pontiac G3 Wave ABS Wheel Speed Sensor

Can I drive my Pontiac G3 Wave with a faulty ABS wheel speed sensor?

You can drive the Pontiac G3 Wave with a failed ABS sensor, but the anti-lock braking system on your G3 Wave 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 Pontiac G3 Wave. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Pontiac G3 Wave?

Use the GeoBrakes vehicle selector and enter the Pontiac G3 Wave year, make, and model. The system displays only the sensors confirmed to fit the Pontiac G3 Wave, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your G3 Wave to avoid receiving the wrong unit.

Do I need to replace all four ABS sensors on my Pontiac G3 Wave at the same time?

No. ABS wheel speed sensors on the Pontiac G3 Wave are independent components and only the failed unit needs to be replaced. However, if your G3 Wave has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Pontiac G3 Wave sensors for corrosion while the wheel is removed.
