Fuel Level Sensor: Description and Operation
DESCRIPTION
The fuel sensor is attached to the modular fuel sender. The resistance of the fuel sensor changes with the fuel level by means of a rheostat. As the
position of the float varies with the fuel level, the rheostat produces a variable resistance. The fuel gauge converts this variable resistance into the fuel
level reading displayed on the instrument panel.
