Code P1501 2003 Ford F150 Description

The P1501 diagnostic trouble code (DTC) for a 2003 Ford F150 indicates that the vehicle speed sensor is out of the self-test range. The vehicle speed sensor (VSS) is a crucial component that monitors the speed of the vehicle and sends this information to the engine control module (ECM) or powertrain control module (PCM). The ECM/PCM uses this data to calculate various parameters such as fuel injection timing, transmission shifting, and cruise control operation.
