Delphi SS20779 ABS Wheel Speed Sensor - Front

Delphi SS20779 Front ABS Wheel Speed Sensor

Delphi SS20779 is a front ABS wheel speed sensor built as a standard replacement for select Ford Transit vans. It uses a 2-terminal male blade connection with a black square connector and includes the wiring harness for a direct service replacement.

• Front ABS wheel speed sensor for select Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD models
• Standard replacement grade for OE-style service work
• Wiring harness included; harness length is 220
• 1 connector, square shape, black color, male connector and male terminal design
• 2 terminals with blade terminal type
• Package includes ABS wheel speed sensor and instruction sheet

OE-Validated Sensor Performance

Delphi develops and validates its vehicle sensors to OE standards, with calibration and testing focused on accurate signal output. For ABS systems, that accuracy matters because the wheel speed signal is used by the vehicle’s braking and stability systems to monitor front wheel rotation. This Delphi SS20779 sensor is a direct-fit service part for front-position applications on 2015-2019 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD models. This part cross-references Standard Ignition ALS2693 for the same application.

Common Issues This Sensor Can Address

• ABS warning light illuminated
• Wheel speed signal loss at the front axle
• Erratic ABS or traction control operation
• Fault codes related to front wheel speed sensor input
• Intermittent braking system communication from a damaged sensor or harness

Installation Notes

Verify the front position and connector style before installation. Inspect the harness routing, connector terminals, and mounting points for damage or corrosion before connecting the new sensor. Confirm the sensor is seated correctly and clear any stored ABS codes after installation. Fits 2015-2019 Ford Transit-150, front; 2015-2019 Ford Transit-250, front; 2015-2019 Ford Transit-350, front; and 2015-2019 Ford Transit-350 HD, front.

Quality Assurance

Delphi sensors are tested and calibrated to OE standards to help deliver accurate readings and reduce comebacks. Part number SS20779 is backed by Delphi’s OE-focused sensor development and validation process.
