Delphi SS21795 ABS Wheel Speed Sensor

The Delphi SS21795 is a direct-fit ABS wheel speed sensor (also known as an anti-lock brake sensor or wheel speed sensor) engineered to restore proper function to your vehicle's anti-lock braking and electronic stability control systems. As a trusted OE supplier, Delphi builds this sensor to match original equipment specifications for a reliable, confidence-inspiring replacement.

How It Works:

The ABS wheel speed sensor monitors wheel rotation speed and sends real-time data to the ABS control module. When the system detects wheel lock-up during hard braking, it modulates brake pressure to maintain steering control and reduce stopping distances. A faulty sensor can trigger an ABS warning light, store a fault code, and disable critical safety systems.

Key Features:

• OE-matched design — like-for-like mounting hardware, connector shape, and wire length for straightforward installation
• Weather-pack connector — seals out dirt, moisture, and chemicals to prevent corrosion and signal loss
• Plated pins — enhanced corrosion resistance and improved electrical conductivity
• Digital signal technology — Hall effect or magneto-resistive design produces a stable square-wave signal, improving accuracy especially at low speeds
• Rigorously tested — subjected to thermal, shock, and vibration testing across a wide temperature range to ensure durability in demanding conditions
• Always new — never remanufactured

The Delphi SS21795 ABS sensor is a safety-critical component and should be replaced with a quality part that meets OE standards. Delphi's engineering heritage as an original equipment manufacturer makes this sensor a trusted choice for professional technicians and informed DIYers alike.
