Chevrolet Traverse ABS Wheel Speed Sensor Guide (2019-2024)
Understanding the common ABS, Traction Control, and Stabilitrak light issues on your Traverse.
- A single failed ABS sensor will disable the ABS, Traction Control, and Stabilitrak systems on your Traverse.
- This is a common, inexpensive, and DIY-friendly repair. A scan tool is needed to identify which sensor has failed.
- Using a high-quality aftermarket brand like Delphi is recommended to avoid potential compatibility issues.
- Before replacing a sensor, have your battery tested, as a weak battery can sometimes trigger similar Stabilitrak warnings.
Understanding ABS Sensor Failure on Your Traverse
If you own a 2019-2024 Chevrolet Traverse, seeing the trifecta of "ABS," "Traction Control Off," and "Service Stabilitrak" warning lights on your dashboard is a common issue. More often than not, the culprit is a single, inexpensive part: a failed ABS wheel speed sensor. This sensor's job is to report wheel speed to the onboard computer. When the signal is lost or incorrect, the computer disables the safety systems that rely on that data as a precaution.
Symptoms of a Bad ABS Sensor
The signs of a failing sensor are hard to miss. Your dashboard will light up with warnings. You may also notice your cruise control no longer works. In some rare cases, you might feel a brief brake pedal pulsation, but typically the system just shuts down. The vehicle's main braking system will still work, but you will not have the anti-lock function in an emergency stop.
Known Issue: Check Your Battery First
Some Traverse owners have reported that a weak or failing battery can cause the "Service Stabilitrak" message to appear, especially during an engine auto-stop/start event. 🎬 Watch: How the autostart cycle can trigger Stabilitrak warnings. If your symptoms are intermittent and happen during auto-stop, it's worth having your battery tested before replacing any sensors.
Choosing the Right Aftermarket Sensor
When it comes to replacing the ABS sensor on your Traverse, you have options. While OEM parts are always a safe bet, quality aftermarket brands can offer significant savings. However, be aware that some Traverse owners have reported issues with certain aftermarket sensors not communicating correctly with the vehicle's computer, causing the warning lights to return even after replacement.
- Delphi: Delphi is a well-respected brand and is often the original equipment (OE) manufacturer for many GM parts. Their sensors are known for quality construction, including weather-pack connectors that resist corrosion—a common failure point. Choosing Delphi is the closest you can get to OEM quality in the aftermarket.
- Standard Ignition (SMP): Standard is a long-standing aftermarket brand with a reputation for producing reliable replacement parts. For a component like an ABS sensor, their standard product line is a dependable and budget-friendly choice. They engineer their parts to match OE fit and function.
Pro Tip: Given the potential for compatibility issues, sticking with a reputable, OE-quality aftermarket brand like Delphi is a wise investment. If you choose another brand and the warning lights return immediately after driving, you may have an incompatible part.

Frequently Asked Questions
Can I replace the ABS sensor myself?
Yes, this is a very DIY-friendly job for someone with basic tools. The sensor is usually held in by a single 10mm bolt. The most common difficulty is the old sensor becoming seized in the wheel hub and breaking during removal, which may require it to be carefully drilled out.
🎬 Watch: How to remove a stuck or broken ABS sensor.Which wheel sensor is bad?
You cannot tell which sensor is bad without a proper diagnostic scan tool. An OBD-II scanner that can read ABS codes is required. It will provide a specific code (like C0040 for the right front wheel) that points directly to the failed sensor.
🎬 See this walkthrough for diagnosing and replacing a front sensor.Do I need to reset the computer after replacing the sensor?
Typically, once the correct new sensor is installed, the warning lights will turn off on their own after you start the car and drive a short distance. However, it is best practice to use a scan tool to clear the stored fault codes from the ABS module after the repair is complete.
Can I just clean the old sensor?
While dirt and debris on the sensor tip can cause issues, failure is more often due to an internal electronic short or a break in the wiring. You can try cleaning it, but if the warning lights are on, the sensor itself has likely failed and needs to be replaced.
