Fuel Level Sensor: 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 position of the float arm. The control module sends the fuel level
information via the Class 2 circuit to the instrument panel cluster (IPC). This information is used for the IPC fuel gage and the low fuel warning
indicator, if applicable. The control module also monitors the fuel level input for various diagnostics.
