Code P1771 Ford Description
The P1771 Ford code indicates a problem with the throttle position sensor (TPS) in the vehicle. The throttle position sensor is a crucial component of the engine management system, as it helps to regulate the amount of air entering the engine, which in turn affects fuel delivery and the overall performance of the vehicle. When the TPS is reporting an open circuit, it means that the sensor is not sending any signal to the engine control module (ECM), leading to potential issues with engine performance and drivability.
