Show original supplier description
The Motorcraft DY1123 is a precision-engineered rear axle vehicle speed sensor (VSS) specifically designed for 1994-2003 Ford trucks equipped with the 7.3L Powerstroke diesel engine. This genuine OEM component is built to meet strict Ford factory standards for durability and reliability, ensuring a precise fit and consistent performance in demanding conditions. Failing speed sensors often lead to diagnostic fault codes such as P0500, erratic speedometer behavior, or issues with transmission shifting, including a flashing overdrive light. Replacing the faulty sensor with this original equipment part provides a direct solution, often resolving speedometer signal loss and transmission management errors. Installation is typically straightforward, with many users reporting the repair can be completed in approximately 10-15 minutes by accessing the sensor on the differential housing.
