Fuel Gauge Sender: Description and Operation
FUEL LEVEL SENSOR
The fuel level sensor consists of a float, a wire float arm, and a ceramic resistor card. The position of the float arm indicates the fuel level. The fuel level
sensor contains a variable resistor which changes resistance in correspondence with the amount of fuel in the fuel tank. The powertrain control module
(PCM) sends the fuel level information via the Class 2 circuit to the instrument panel (IP) cluster. This information is used for the IP fuel gauge and the
low fuel warning indicator, if applicable. The PCM also monitors the fuel level input for various diagnostics.
