Delphi SS21503 ABS Wheel Speed Sensor

The Delphi SS21503 is a direct-fit ABS wheel speed sensor designed to restore proper function to your vehicle's anti-lock braking and electronic stability control systems. As a critical safety component, this sensor continuously monitors wheel rotation speed and transmits accurate data to the ABS control module, helping prevent wheel lockup during hard braking events.

Key Features:

• OE-quality construction engineered to meet original equipment specifications for accurate, reliable performance
• Digital signal technology using magneto-resistive or Hall effect design delivers a clean square-wave signal that only changes frequency — not amplitude — for improved accuracy at low speeds
• Weather-sealed connector with plated pins resists corrosion and ensures signal integrity in harsh operating conditions
• Like-for-like mounting, connector design, and wire length for straightforward, no-modification installation
• Rigorously tested to OE standards for fit, function, and long service life
• Sold as a single sensor

The Delphi SS21503 ABS sensor is built by one of the industry's most trusted original equipment suppliers. Choosing an OE-quality replacement ensures your anti-lock braking system and related safety systems — such as traction control and electronic stability control — operate as designed.
