Understanding ABS Sensor Failure on Your Yukon
If you own a 2016-2020 GMC Yukon, seeing the ABS, Traction Control, or "Service StabiliTrak" light on your dashboard 🎬 Watch this guide to fixing StabiliTrak and Traction Control lights. is a common reason to suspect a problem with a wheel speed sensor. These sensors are exposed to harsh conditions at the wheels and can fail over time due to contamination, damage from road debris, or internal electronic failure. When a sensor fails, it can no longer send an accurate speed reading to the vehicle's computer, triggering warning lights and disabling key safety systems.

General Motors issued a recall for certain 2015-2020 GMC Yukon models equipped with a 5.3L engine, 3.08 rear axle, and four-wheel drive. A wheel speed sensor failure on these specific vehicles could cause a software error in the Electronic-Brake Control Module (EBCM). This can lead to unexpected braking on the opposite wheel when driving between 41 and 60 MPH in 4WD or Auto mode, causing the vehicle to pull to one side. The fix is a free software update for the EBCM performed by a dealer. You can check if your vehicle is affected by visiting the NHTSA website with your VIN. Until the repair is done, driving in 2WD mode can prevent this specific issue.
Choosing the Right Aftermarket ABS Sensor
When replacing an ABS sensor, you don't have to go back to the dealership. Several reputable aftermarket brands offer quality replacements. The key is to understand the difference between OEM suppliers and other aftermarket brands.
- OEM-Level Quality (ACDelco, Delphi): ACDelco is GM's own parts brand, and their "GM Original Equipment" line is the same part your Yukon was built with. Delphi is another major original equipment manufacturer for GM and many other carmakers. Choosing either of these brands is the closest you can get to the original part's performance and reliability. They are highly recommended for electronic components like ABS sensors.
- Trusted Aftermarket Brands (Standard Ignition, Holstein, Walker Products): Brands like Standard Motor Products (Standard Ignition) and Holstein have a long history of producing reliable aftermarket components. They are designed to meet or exceed original specifications and offer a great balance of quality and value. Forum discussions show that many DIYers have good experiences with these brands for sensors.
- Value-Oriented Brands (True Tech): These brands provide a functional replacement at a very accessible price point. While they may not have the same long-standing reputation as OEM suppliers, they can be a good option for budget-conscious repairs, though long-term durability can sometimes be a concern compared to premium brands.
Pro Tip: On these GM trucks and SUVs, a failing wheel bearing can sometimes cause ABS sensor issues. A worn bearing can have excess play, which changes the distance between the sensor and the toothed ring it reads, leading to an erratic signal. If you replace a sensor and the problem returns, have your wheel bearings inspected.

Frequently Asked Questions (FAQ)
Can I drive my Yukon with a bad ABS sensor?
Yes, but with caution. Your normal brakes will still work, but the anti-lock braking (ABS), traction control, and stability control systems will be disabled. This means your wheels can lock up during a panic stop, increasing stopping distances and reducing steering control, especially on wet or slippery roads. It is highly recommended to get the sensor replaced as soon as possible to restore these important safety features. Due to the recall (N192261050), certain 4WD models have an increased risk of the vehicle pulling to one side, so driving in 2WD is advised until it's fixed.
Is replacing an ABS sensor a DIY job?
Yes, for many people with basic mechanical skills. The sensor is typically held in by a single bolt on the wheel hub assembly. The process involves safely jacking up the vehicle, removing the wheel, unbolting the old sensor, and tracing its wire to a connector to unplug it. The most common difficulty 🎬 See how easy it is to replace the sensor yourself. is the sensor becoming seized in the hub due to rust, which may require extra effort to remove. Always use a torque wrench for the final installation.
Where is the ABS sensor located on my Yukon?
Your 2016-2020 Yukon has one ABS wheel speed sensor at each of the four wheels. It is mounted on the wheel hub or steering knuckle, right behind the brake rotor. The sensor's wire harness is routed along the suspension components and frame, secured by clips, before plugging into the main vehicle harness.
Do I need to replace the wheel hub assembly with the sensor?
Not usually. The ABS sensor is available as a separate part. However, on some GM trucks, the sensor is integrated into the wheel hub bearing assembly. In other cases, if the wheel bearing is failing, it can damage the sensor or cause the same warning lights. A mechanic might recommend replacing the entire hub assembly if the bearing is worn out, which would include a new sensor.
