Code P0462 1998 Ford F150 Description

The diagnostic trouble code P0462 for a 1998 Ford F150 indicates a Fuel Level Sensor Circuit Low Input. This means that the fuel level sensor in the vehicle is reporting a lower than expected voltage signal to the engine control module (ECM). The fuel level sensor is responsible for sending information about the amount of fuel in the gas tank to the ECM, which then uses this data to calculate fuel consumption, adjust fuel mixture, and display the fuel level on the dashboard gauge.
