Code P1120 2012 Ford Fusion Description
The P1120 diagnostic trouble code for a 2012 Ford Fusion indicates that the throttle position sensor is out of range. The throttle position sensor (TPS) is a crucial component of the vehicle's fuel injection system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). When the TPS is out of range, it means that the sensor is not providing accurate data to the ECM, which can lead to issues with fuel delivery and engine performance.
