According to the DTC Codes:

P0460 - Fuel Level Sensor Circuit Malfunction The PCM monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified fuel fill percentage in the fuel tank. Empty fuel tank
Fuel pump (FP) module stuck open
Incorrectly installed fuel gauge
Damaged instrument cluster
CASE GND circuit open
FLI shorted to VPWR
Damaged PCM
Overfilled fuel tank
Fuel pump (FP) module stuck closed
Damaged fuel gauge
FLI circuit open
FLI circuit shorted to CASE GND or PWR GND
CSE GND shorted to VPWR
Monitor FLI PID and FLI V PID in key ON engine RUNNING. FLI PID at 25% fill (with non matching fuel gauge) and FLI V PID less than 0.90 volts [for FLI PID at 75% fill (with non matching fuel gauge) and FLI V PID greater than 2.45 volts] indicates a hard fault.

Maybe some one that has seen this code before can chime in to narrow it down.

Good luck
