Guide to the 2007-2015 GMC Yukon ABS Wheel Speed Sensor
Understand the common signs of failure and how to choose the right replacement ABS sensor for your Yukon.
- A bad ABS sensor is a very common cause for ABS, StabiliTrak, and Traction Control warning lights on a 2007-2015 Yukon.
- Symptoms include warning lights and unwanted ABS activation (grinding/pulsing) at low speeds.
- For best results, choose a premium aftermarket brand like ACDelco, Bosch, or Delphi.
- Replacement is a DIY-friendly job, but a scan tool is needed to know which sensor has failed and to clear the codes afterward.
Is your GMC Yukon showing ABS or StabiliTrak warnings? It might be a bad wheel speed sensor.
If you own a 2007-2015 GMC Yukon, you're likely familiar with the dashboard alerts for the ABS, StabiliTrak, and traction control systems. A common cause for these warnings is a failing ABS wheel speed sensor. These sensors live in a harsh environment near the wheels, exposed to dirt, water, and road debris, which can lead to their failure over time. On this generation of Yukon, a faulty sensor can cause a number of issues, from annoying warning lights to serious braking problems.
Known Issues for 2007-2015 GMC Yukon
Erratic ABS Activation: A very common complaint for these trucks is the ABS system engaging at low speeds, like when pulling into a parking spot. This can feel like a grinding noise or a pulsating brake pedal and is often caused by rust and debris building up between the sensor and the wheel hub bearing, creating an incorrect air gap. Sometimes, simply cleaning the mounting surface and the sensor can resolve the issue, but often the sensor itself needs replacement.
Service StabiliTrak Message: A failing wheel speed sensor is a primary culprit for the "Service StabiliTrak" and "Service Traction Control" messages on the driver information center. Because the stability system relies on accurate wheel speed data, a bad sensor will cause the system to disable itself and trigger the warning.
Technical Service Bulletin (TSB) PIT4056H: GM issued a bulletin related to a loss of communication with the Electronic Brake Control Module (EBCM), which can set a U0121 code. The bulletin notes that a shorted or faulty wheel speed sensor or its wiring can cause this condition, leading technicians to unplug each sensor one by one to isolate the problem.
Choosing the Right Aftermarket ABS Sensor
When it's time to replace a sensor, you don't have to go back to the dealer. The aftermarket offers a wide range of options, but quality can vary. Here’s a breakdown of what to look for.
Brand Tiers
- OEM & Premium Aftermarket (ACDelco, Bosch, Delphi, NGK/NTK): ACDelco is the original equipment manufacturer for GM, so their parts offer a direct fit and factory performance. Brands like Bosch, Delphi, and NGK (NTK) are also highly respected OEM suppliers for many carmakers and are known for their quality and reliability. Choosing one of these brands is the safest bet for a long-lasting repair.
- Quality Mid-Range (Standard Motor Products, Dorman, Hella): These brands are popular in the aftermarket. Standard Motor Products (SMP) often provides a solid alternative to OEM. Dorman is known for making a huge variety of replacement parts, though some professional mechanics have mixed opinions on their electronic components. They can be a good value, but for critical sensors, sticking to a premium brand is often recommended.
- Economy Brands (Holstein, Skyward, True Tech, Walker Products): These brands offer the most budget-friendly prices. They can be a viable option if cost is the primary concern, but their longevity and performance may not match the higher-tiered brands. For a part that is relatively easy to replace and low-cost, some owners find success with these brands.
Pro Tip: Consider the Whole Hub
The ABS sensor is mounted directly to the wheel hub and bearing assembly. Often, when a wheel bearing starts to fail, the increased play and vibration can damage the ABS sensor. Many mechanics and experienced owners recommend replacing the entire wheel hub assembly, which includes a new bearing and a new ABS sensor, especially on higher-mileage vehicles. While more expensive upfront, it can save you from doing the job twice.
How Much Does a Replacement Cost?
The cost depends on whether you do it yourself or go to a shop.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket ABS Sensor | $21 - $99 |
| New OEM ABS Sensor | $60 - $100 |
| Shop Labor Cost | $117 - $172 |

Frequently Asked Questions
Can I replace just one ABS sensor?
Yes. The sensors operate independently, so you only need to replace the one that has failed. A proper diagnostic scan tool that can read ABS codes is needed to identify which specific sensor is faulty.
Is it hard to replace a Yukon ABS sensor?
For a DIYer with some experience, it's a manageable job. It involves removing the wheel and brake caliper to access the sensor. The sensor is held in by a single bolt, but sometimes corrosion can make it difficult to remove. The wiring harness is then unclipped and disconnected.
🎬 See a step-by-step guide on changing your wheel speed sensor.Do I need to clear the codes after replacing the sensor?
Yes. After replacing the faulty sensor, the diagnostic trouble codes (DTCs) stored in the computer must be cleared with a scan tool. In most cases, the warning lights will not turn off on their own until the codes are cleared.
What's the difference between a front and rear sensor?
Front and rear sensors are not interchangeable. They have different shapes, mounting points, and harness lengths. You must order the correct sensor for the specific wheel location (e.g., front left, rear right).
