Low Fuel Lamp/Indicator: Description and Operation
The resistance of the fuel tank unit varies according to the float position in the fuel tank. When the fuel tank has an adequate amount of fuel, the low fuel
indicator light circuit is open and the indicator light will not come ON.
The fuel level output is received by the Engine or Powertrain Control Module (ECM or PCM) (ECM with M/T or PCM with A/T) and when the fuel
level drops to almost empty, the ECM or PCM closes the circuit and the low fuel indicator light comes ON.
