AUTOKAY Front ABS Wheel Speed Sensor Pack — 2 PCS Front Left & Right for Chevrolet Equinox / GMC Terrain, OE-fit connectors

AUTOKAY's two-piece front ABS wheel speed sensor set replaces OEM part numbers 20811371 and 20811372 to restore accurate wheel-speed input for compatible Chevrolet Equinox and GMC Terrain models.

If your ABS, traction control, or stability light has come on, or if you’ve noticed uneven braking feedback, a faulty wheel speed sensor can be the cause. This AUTOKAY pack contains both front left and front right sensors (the blue plug marks the front right, the yellow plug marks the front left), engineered to match the fit and electrical connectors for specific Equinox and Terrain years and trims. The set is supplied as two sensors so you can replace both sides at once for consistent signal output and simplified installation.

How do these sensors help with braking and stability systems?

Wheel speed sensors monitor each wheel’s rotational speed and send the signal to the ABS/ECU. Accurate readings allow the vehicle systems to regulate braking force and traction control; replacing a degraded sensor can clear warning lights and improve system responsiveness.

• Restores reliable wheel-speed signals to ABS and traction-control modules.
• Helps eliminate false ABS/traction warnings due to bad sensor input.
• Sold as a matched pair for symmetrical signal output front left and right.

What do I get in the package and how do I tell left from right?

The package includes two front wheel speed sensors—one for each side—so you can replace both simultaneously. AUTOKAY uses colored connectors to simplify installation identification.

• Includes 2 PCS: front left and front right ABS wheel speed sensors.
• Yellow connector = front left sensor; blue connector = front right sensor.
• Pre-molded wiring and OE-style plugs for plug-and-play replacement.

Are these sensors easy to install and what should I check during replacement?

Installation is straightforward for anyone comfortable with basic wheel and brake work; you’ll generally remove the wheel and hub shield to access the sensor. Inspect the mounting hole, wiring harness, and tone ring for damage while replacing the sensor to avoid repeat failures.

• Typically requires wheel removal and access to the hub area.
• Check tone ring and connector pins for corrosion or damage before fitting.
• Torque mounting hardware to manufacturer specs and secure wiring routing.

Who is this for: This AUTOKAY front ABS wheel speed sensor pair is intended for DIY mechanics and professional technicians repairing Chevrolet Equinox or GMC Terrain vehicles listed above who need an exact-fit replacement for front left and right sensors. It's useful if you’re replacing worn or damaged sensors, addressing ABS/traction system warnings, or restoring consistent wheel-speed readings after hub, brake, or suspension service. Always verify fitment with your vehicle year, trim, and OEM part numbers before ordering.
