fuel level sensor

The DTC code would point to fuel level sensor wiring problems. Under the rear passenger seat, check the connections and wiring for loose or chafed wires or corrosion. If no problems are immediately apparent, the problem may be in the pump unit itself. The fuel level sender is integrated into the pump unit. The tank needs to come out for pump replacement.
Which gauge(s) wasn't (weren't) working? If the problem is more than just the fuel gauge, it may be something different.

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.
Causes:
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.

check the fuse under your dash #50 should be a 7.5amp fuse something to do with the fuse and gauges up front throws a code and causes these problems from what im reading
