AUTOKAY Front ABS Wheel Speed Sensors for Chevy Equinox & GMC Terrain 2010–2017 — Left & Right, OE Fit

AUTOKAY front ABS wheel speed sensor pair (20811371 & 20811372) replaces worn sensors on compatible Chevy Equinox and GMC Terrain models to restore accurate wheel speed data for ABS and stability systems.

When a wheel speed sensor wears out, dashboard warnings, inconsistent ABS behavior, or stability control alerts can appear. These AUTOKAY sensors are sold as a front left and right pair and cross-reference OE numbers like 20811371, 8543704500, ALS1994, and 14602750. They are designed to match the fit and electrical interface of the originals so you can swap them in without custom wiring or major modifications.

Which vehicles will these sensors fit?

These sensors are engineered for specific Chevrolet Equinox and GMC Terrain model years and submodels. Confirm your vehicle year and trim before ordering to ensure compatibility. They cover many popular trims across the 2010–2017 production span.

• Chevrolet Equinox: 2010–2017 (LS, LT), 2010–2016 LTZ, 2015–2017 L, 2017 Premier
• GMC Terrain: 2010–2016 (SLE, SLT), 2013–2016 Denali, 2015–2016 SL
• Replaces OE numbers: 20811371, 8543704500, ALS1994, 14602750

How straightforward is installation for the front left and right sensors?

Installation is typically a bolt-and-plug replacement that most home mechanics or professional technicians can handle. The sensors are provided as a matched front pair, which simplifies servicing both sides at once and helps avoid inconsistent wheel speed readings after a single-sided replacement.

• Comes as 2 pieces: front left and front right sensors
• Direct electrical connector to original harness—no splicing required
• Standard mounting points to match factory hardware and clips
• Recommended inspection of tone ring and connector for damage during installation

What materials and design aspects improve durability?

AUTOKAY sensors are built to withstand road debris, moisture, and typical temperature ranges encountered on passenger vehicles. While they are not lifetime components, the construction aims to provide stable output and a reliable physical connection to the vehicle’s wiring harness.

• Sealed connector to resist moisture intrusion
• Durable sensor housing to resist chips and road impact
• OEM-equivalent electrical specifications for accurate signal output
• Quality control checks to ensure consistent performance between pair units

Will replacing both sensors at once prevent future issues?

Replacing both front sensors simultaneously can prevent mismatched readings and uneven wear between sides. It also reduces the chance of a second failure shortly after replacing only one sensor, saving time and labor costs in the long run.

• Matches sensor output characteristics across both front wheels
• Reduces callbacks for repeated ABS or traction control faults
• Often recommended when vehicle has high mileage or both sensors show wear
• Packaged pair simplifies parts ordering and reduces diagnostic ambiguity

Who is this for: Drivers and technicians who own or service Chevrolet Equinox or GMC Terrain models within the listed years and trims and who need a reliable front left and right ABS wheel speed sensor replacement. These AUTOKAY sensors are suited for routine ABS repair, preventative maintenance when replacing worn components, and situations where matching both front sensors is preferred to restore consistent wheel speed signals.
