WHAT IS THE BEST WAY TO FIX A PO463 CODE

The P0463 is a fairly straight forward code pointing to a fault in the Fuel Level Sensor. It's mounted to the side of the fuel pump assembly, located inside the fuel tank. Check the wires harness going to the pump assembly for any loose, broken or rubbed through wires. If the harness looks good, replacing the Fuel Level Sensor should solve the problem.
