Code P1501 Ford Description

The P1501 Ford code indicates that the vehicle speed sensor is out of the self-test range. The vehicle speed sensor (VSS) is an essential component of the vehicle's onboard computer system, as it provides the necessary data for various systems to function properly. The VSS measures the speed of the vehicle and sends this information to the engine control module (ECM) and other relevant systems. When the VSS is out of the self-test range, it means that the signal being received by the ECM is either erratic or not within the expected parameters.
