Delphi SS20127 Abs Wheel Speed Sensor

The Delphi SS20127 is a direct-fit ABS wheel speed sensor engineered to OE specifications. As a Tier 1 original equipment supplier to the world's leading automakers, Delphi builds its aftermarket sensors with the same standards and materials used in factory production, ensuring a reliable, like-for-like replacement.

Key Features:

• OE-matched design — like-for-like mounting, connector design, and wire length for straightforward installation straight from the box
• Plated connector pins — corrosion-resistant plating helps prevent failure caused by internal and cable short circuits
• Weather-pack connectors — lock out dirt, moisture, and chemicals to protect against contamination in harsh environments
• Digital output signal — magneto-resistive or Hall-effect technology delivers a stable square-wave signal for maximum signal-to-noise ratio and accurate readings at low speeds
• Rigorous thermal testing — validated across a temperature range of -40°C to 140°C for dependable performance in extreme conditions
• OE heritage — backed by over 100 years of original equipment manufacturing experience

The ABS wheel speed sensor continuously monitors wheel rotation speed and transmits data to the ABS control module to prevent wheel lock-up during braking. A failed sensor will typically trigger an ABS warning light and store a diagnostic fault code. The Delphi SS20127 restores proper ABS, traction control, and electronic stability system function with a quality replacement built to last.
