Why does my gas gauge read full or above?
If the gauge reads full or above with the wire disconnected, the problem is in the tank unit rather than the wiring. It could be an electrical fault, or the float may be stuck or may have sunk because of a hole caused by corrosion. Remove the tank sending unit and check it.
What causes the gas gauge needle to move?
The variations in the amount of fuel in the tank cause the arm to move. This changes the resistance of the tank unit, changing the amount of current at the gauge unit coils, which in turn moves the needle located between the coils.
