Those numbers are trouble codes stored in the PCM's memory and don't directly refer to parts. It's never a good idea to replace parts without first confirming the failure by means of the recommended diagnostic procedure. Code P0463 was set due to a high-voltage fault in the fuel-level sensor circuit. This may be caused by a bad sensor, the powertrain control module, or a short in the applicable circuit. The problem may be a defective fuel level sensor in the fuel tank.
P0483-FAN SPEED When Monitored: While the engine is running. Set Condition: The actual fan speed is less than 75 RPM or more than 4000 RPM. The computer controlled fan clutch has failed.
