Code P0463 2005 Ford Explorer

the service engine soon light went on

with less than 33,000 miles. i plugged the scanner and got the code P0463. Any idea what this means and what i need to do.

P0463 Fuel level Sensor Circuit High Input. Not sure what fuel level its sensing, but something with emissions. Maybe someone else can be more specific.


The first suspect is the fuel level sender in the gas tank. Since you don’t have the factory scan tool (right?), you could back-probe the wire at the gas tank electrical connection which carries the level signal (voltage) to the engine computer. If it’s less than 2.5 volts, the fuel level sender’s resistance,with the gas tank on empty, is too low. Cut power. Disconnect electric plug. Measure sender resistance. (I don’t know what it should be).
