Guide to the ABS Speed Sensor on a 2010-2017 Chevrolet Equinox
Understanding why your ABS, Traction Control, and StabiliTrak lights are on and how to fix the problem.
- A bad ABS sensor on a 2010-2017 Equinox will trigger the ABS, Traction Control, and StabiliTrak warning lights.
- The issue could be the sensor itself or the magnetic ring on the wheel hub; a scan tool is needed to diagnose the specific fault code.
- Replacement is a simple DIY job for many, requiring basic tools and taking less than an hour.
- Aftermarket sensors are a cost-effective alternative to OEM parts, with prices often under $30.
Common Symptoms of a Failing ABS Sensor
When an ABS speed sensor starts to fail on your Equinox, your vehicle's computer will usually let you know right away. The most common sign is a combination of warning lights on your dashboard.
- ABS Warning Light: This is the most direct indicator. A faulty sensor will cause the ABS computer to log a fault and turn on the light.
- Traction Control Light: Because the traction control system relies on the same wheel speed data, its warning light will often come on as well.
- Service StabiliTrak Message: The StabiliTrak stability system also becomes disabled, and you will see a warning message for it. 🎬 Watch: Diagnosing the Service StabiliTrak message on your Equinox
- Pulsating Brake Pedal: In some cases, a faulty sensor can send incorrect readings, making the ABS system think a wheel is locking up. This can cause the brake pedal to pulsate at low speeds.
A Note on the Magnetic Encoder Ring
For the 2010-2017 Equinox, the ABS sensor reads a magnetic ring (encoder ring) that is part of the wheel bearing hub assembly. Sometimes, the warning lights are not caused by a bad sensor, but by this ring being cracked, damaged, or covered in metallic debris. If the ring is damaged, the entire wheel hub assembly needs to be replaced.
Choosing the Right Aftermarket ABS Sensor
When it's time to replace your ABS sensor, you have options outside of the original equipment (OEM) part from the dealer. Aftermarket parts can offer significant savings. They generally fall into two categories:
- Value/Budget Brands: These are the most affordable options and meet the basic requirements to get the job done. For a common part like an ABS sensor, these can be a good choice, especially for an older vehicle. They are designed to match the original's fit and function.
- Premium Aftermarket Brands: Brands like Duralast, NTK, and Delphi often position themselves as equal to or better than OEM quality. They may use higher-grade materials and undergo more rigorous testing. For a critical safety component, spending a few extra dollars for a premium aftermarket part can provide extra peace of mind.
For the Chevrolet Equinox, many owners find that a quality aftermarket sensor works just as well as the OEM part for a fraction of the price. The key is to buy from a reputable seller that offers a warranty.

Frequently Asked Questions
Can I drive my Equinox with a bad ABS sensor?
Yes, but you should get it fixed soon. Your regular brakes will still work, but the anti-lock (ABS), traction control, and StabiliTrak features will be disabled. This means your vehicle won't have the extra safety assistance during emergency braking or on slippery surfaces.
Is replacing the ABS sensor a DIY job?
Yes, for most people with basic tools, this is a straightforward DIY repair. The sensor is usually held in by a single bolt and an electrical connector. The main challenge can be if the old sensor is corroded and stuck in the wheel hub. The job typically takes less than an hour per wheel.
🎬 Watch: Step-by-step guide to replacing the front ABS sensorWhich wheel has the bad sensor?
You can't tell just by the warning lights. You will need an OBD-II scanner that can read ABS codes. These codes, such as C0035 (Front Left) or C0050 (Right Rear), will tell you exactly which wheel's sensor is reporting a fault. 🎬 See how to diagnose and repair a C0035 sensor code Many auto parts stores will scan your codes for free.
Do I need to replace the sensors in pairs?
No, you only need to replace the sensor that has failed. However, they are relatively inexpensive, and since they are exposed to the same conditions, some owners choose to replace them in pairs (both fronts or both rears) as preventative maintenance, but it is not required.
Are there any recalls for the ABS sensor on the 2010-2017 Equinox?
No, there are no specific recalls from GM or NHTSA for the ABS wheel speed sensors on the 2010-2017 Chevrolet Equinox. However, GM did issue a Technical Service Bulletin (TSB) for the 2013 model year regarding issues with the rear sensor harness connectors not being fully seated, which could cause similar symptoms. Another TSB from 2017 notes that debris on the magnetic encoder ring can cause false readings.
