We just bought TODAY a '03 Ram 3500 dually with the 5.9. Apparently I've inherited some baggage from the previous owner. It threw 3 codes on the ignition check.
PO463- Fuel sensor 1 high
PO462- Fuel sensor 1 low
PO500- Vehicle speed sensor

Does anyone know what these codes pertain to, and how severe it may be? Any help would be appreciated. The truck runs great with no other problems I know of.
