Detailed Description

Delphi SS20936 is an ABS wheel speed sensor designed for the rear position on compatible Chevrolet and GMC vehicles. Delphi tests and calibrates its sensors to OE standards, which helps ensure the ABS module receives precise wheel speed data. That accuracy is important for vehicles like the Chevrolet Blazer, Chevrolet S10, GMC Jimmy, and GMC Sierra 2500 HD, where stable rear wheel speed input supports proper anti-lock brake operation. This part cross-references Standard Ignition SC86 for the same application.

What It Helps Address

• ABS warning light caused by a failing rear wheel speed sensor
• Erratic or missing wheel speed signal at the rear axle
• ABS activation concerns related to inaccurate sensor readings
• Brake system fault codes tied to rear sensor performance
• Intermittent braking control issues on GM rear ABS systems
