Fuel Gauge

The instrument cluster receives the fuel signal via the hard-wired circuitry form the fuel pump module. The fuel pump module changes resistance according to the amount of fuel in the fuel tank and varies the current flow through the fuel gauge. A low resistance will result in a lower gauge indication, while a high resistance will result in a higher gauge indication. The fuel gauge is controlled by the instrument cluster micro processor and varies the position according to data received form the fuel pump module.
