P1450 Ford is a diagnostic trouble code (DTC) for "Fuel Level Sensor Circuit Malfunction". This code is set when the powertrain control module (PCM) detects a problem with the fuel level sensor or the circuit that it is operating in. There are a few different things that can cause this code to set, but the most common is a problem with the fuel level sensor itself. Other possible causes include a short in the sensor circuit or a problem with the PCM.
