Delphi SS21577 ABS Wheel Speed Sensor

The Delphi SS21577 ABS Wheel Speed Sensor is a direct-fit replacement sensor engineered to restore precise wheel speed monitoring to your vehicle's anti-lock braking system. As a trusted original equipment supplier to the world's top automakers, Delphi manufactures this sensor to meet or exceed OEM specifications, delivering the same reliable performance as the part your vehicle was built with.

The ABS wheel speed sensor continuously measures wheel rotation speed and transmits that data to the vehicle's ABS control module. This signal is critical for preventing wheel lockup during braking, and also supports traction control and electronic stability control systems. On vehicles with automatic transmissions, wheel speed data is also used by the Powertrain Control Module (PCM) to optimize shift points.

Key Features:

• Manufactured to meet or exceed OE specifications for dependable braking performance
• Plated connectors help resist corrosion and prevent failures caused by internal and cable short circuits
• OE-matched design helps prevent mechanical damage to the sensor ring, soiling, and issues from increased wheel bearing free play
• Engineered for consistent digital output and maximum signal-to-noise ratio
• Maintains stable performance across a wide range of temperatures for long-lasting durability
• Backed by Delphi's stringent OE development and product validation standards

The Delphi SS21577 is a reliable, OE-quality replacement for restoring full ABS, traction control, and stability system functionality.
