The fuel level sensor transmits an accurate reading of your current fuel level to your fuel gauge. A functioning fuel level sensor is required for an accurate representation of your current fuel level. Fuel level sensors come in varying types and are model-specific.
These Sensors are known by the following terms:
The fuel level sensor sends an electric signal to your fuel gauge. This sensor works like a float in your fuel tank to determine the amount of fuel contained within the fuel tank. In some vehicles, the fuel pump and fuel level sensor are combined into a single unit.
In your motor vehicle this fuel level sensor usually contains these components:
The sensing unit typically uses a float connected to a potentiometer. As the degree of fuel in the fuel tank is consumed, the float drops and slides a moving contact along with the resistor. When the fuel level reaches a certain point, it will also turn on a low fuel light on some vehicles.
Meanwhile, the indicator unit is measuring and displays the amount of electric current flowing through the sending unit. When the tank level is high and the maximum current is flowing, the needle points to "F" indicating a full tank. When the tank is empty, and the least current is flowing, the needle points to "E" indicating an empty tank.
What are the warning signs of a Bad or Failing Fuel Gauge Sender
Purchasing a new fuel level indicator from KLM Performance will restore your ability to tell how much fuel is in your tank.
