• Wiring harness included for a direct repair approach
• Black connector with square shape
• 2-terminal male blade pin connection
• Wiring harness length: 599
• Package contents: ABS wheel speed sensor and instruction sheet

OE-Validated Sensor Performance

Delphi develops vehicle sensors using OE-focused validation methods, and the SS21676 follows that approach for accurate signal output and dependable fitment. This rear ABS wheel speed sensor is built for 2018-2023 Chevrolet Equinox rear applications, 2018-2023 GMC Terrain rear applications, and 2017 Buick Envision rear applications. The Delphi SS21676 is also cross-referenced to Standard Ignition ALS3088 for the same application.

What This Sensor Helps Address

• ABS warning light caused by a failing rear wheel speed sensor
• Erratic or missing wheel speed data at the rear axle
• Brake control system faults related to sensor signal loss
• Traction control or stability system issues tied to wheel speed input
• Comebacks caused by inaccurate sensor readings

Installation Notes

Verify rear position, connector style, and harness routing before installation. The SS21676 uses a square black connector with a male blade pin terminal layout and includes a wiring harness, so matching the original connection points is important for a clean repair. Confirm vehicle application by year, make, and model before ordering, especially on Chevrolet Equinox, GMC Terrain, and Buick Envision rear ABS sensor replacements.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and validates them through stringent development methods. That focus on OE-level signal accuracy helps support reliable braking system operation and reduces the chance of repeat repairs.
