Detailed Description

Delphi SS21249 is part of Delphi’s sensor portfolio for vehicle speed and brake system applications. For 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator front-right service, this ABS wheel speed sensor provides the signal the ABS module uses to monitor wheel rotation and respond during braking events. This part cross-references Standard Ignition ALS528 for the same application.

Common Issues This Part Can Address

• ABS warning light caused by a failed wheel speed sensor
• Erratic or missing wheel speed signal at the front right wheel
• ABS system fault codes related to wheel speed input
• Brake pulsation or ABS activation concerns tied to sensor signal loss
• Intermittent traction control or stability system warnings linked to wheel speed data

Installation Notes and Tips

Confirm the vehicle position before ordering, since SS21249 is listed for front-right service on the applications shown. Inspect the connector, wiring path, and tone ring or hub area during replacement, and compare the old sensor to the new unit before installation. Use the included instruction sheet and verify proper seating of the threaded terminal connection.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and uses OE development and validation methods. That focus on signal accuracy supports dependable ABS operation on Ford Expedition and Lincoln Navigator applications.
