2005 Infiniti G35

2005 Infiniti G35
I have a 2005 Infiniti G35 (3.5L) with 140K. My fuel gauge has started to read near full at all times and give me P0462 error codes. I replaced both the driver side fuel sensor unit and the passenger side unit (part of the fuel pump assembly). This had no effect on the problem. I still get P0462 errors and the fuel gauge isn’t working correctly. I self tested the instrument cluster and everything tested OK. I also put an Ohm meter on the fuel sensors (both units) while manually changing the float position and I did see the Ohm readings change on both units. I don’t know where to go from here. Any help would be greatly appreciated.
