The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the combination meter. The combination meter sends the fuel level sensor signal to the ECM through CAN communication line. It consists of two parts, one is a mechanical float and the other is a variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
