Description of functions

The combination meter ASSY uses the fuel sender gauge ASSY to detect the fuel level in the fuel tank. The fuel sender gauge ASSY has a variable resistor that changes its resistance depending on the fuel level. The fuel sender gauge ASSY receives voltage from the combination meter ASSY and adjusts its voltage based on the resistance that changes according to the fuel level in the fuel tank. The combination meter ASSY detects the voltage between the variable resistor and the resistor inside the combination meter ASSY, and drives the fuel receiver gauge.
