I've got a 99 Grand Cherokee and the fuel gauge fluctuates from full to empty (regardless of how much fuel is actually in the tank). The Trouble Code is P0462: Fuel Level Sending Unit Volts Too Low. I've replaced the in-tank fuel sending unit (along with the fuel pump), but this has not fixed the problem. I'm contemplating replacing the in-dash fuel gauge next even though it still shows movement when doing the dash test (hold down odometer reset button then turn key on).

Has anyone had this same issue? Can anyone offer a solution?

Thanks,
Caleb :o)
