Code P0462 2007 Ford Fusion Description

The P0462 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates that the fuel level sensor 'A' circuit is reading a lower voltage than expected by the Engine Control Module (ECM). This sensor is responsible for sending information about the fuel level in the tank to the ECM, which then displays this information on the fuel gauge in the dashboard. When the sensor circuit is reading a low voltage, it means that the fuel level sensor is not functioning properly, leading to inaccurate readings on the fuel gauge.
