Detailed Product Information

Delphi SS21427 is engineered for rear right wheel speed monitoring on 2017-2019 Ford F-250 Super Duty and 2017-2019 Ford F-350 Super Duty models. As an ABS wheel speed sensor, it sends the braking system the wheel rotation data needed for proper ABS operation and traction-related control functions. Delphi validates and calibrates its sensors to OE standards, helping maintain consistent readings and reducing repeat repairs.

This part number, SS21427, is a practical OE-style replacement for technicians and owners servicing Ford Super Duty brake sensor faults. The square connector, female connector gender, male blade terminals, and included harness support a straightforward replacement on the rear right side.

Common Issues This Part Addresses

• ABS warning light illuminated on the dash
• Wheel speed signal loss at the rear right corner
• Intermittent ABS or traction control fault codes
• Erratic braking-system sensor readings
• Sensor failure from wear, contamination, or wiring damage

Installation Notes and Tips

Verify rear right placement before installation and compare the connector shape, terminal count, and harness routing to the original sensor. Inspect the tone ring, hub area, and nearby wiring for damage or corrosion before installing the new sensor. Clear stored ABS codes after replacement and confirm proper wheel speed data with a scan tool.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for accurate readings. That level of calibration supports dependable brake-system performance on Ford F-250 Super Duty and Ford F-350 Super Duty applications.
