What are the symptoms of a faulty fuel level sensor?

[Erick]

The symptoms of a faulty fuel level sensor include the fuel gauge not displaying the fuel level or displaying inaccurate readings, making it impossible for the driver to know the amount of fuel in the gasoline tank. Here is some relevant information about the fuel level sensor: 1. The fuel level sensor is essentially the car's fuel quantity sensor. It drives a wound sliding resistor, where changes in fuel level cause variations in the resistor's resistance, thereby enabling fuel measurement. 2. In most cases, the car's fuel level sensor is integrated with the fuel pump. The sensor floats on the fuel surface due to buoyancy, with the float's position indicating the liquid level. The shape of the fuel tank allows for determining the volume of fuel inside the storage tank.
