Fuel Gauge: Description and Operation

FUEL GAGE

The fuel level sender sends fuel level percent to the instrument panel cluster (IPC). The IPC displays the fuel level as determined by the fuel level sender. The IPC receives a message from the fuel level sender indicating the fuel level percent. The fuel gage defaults to E (empty) if the IPC detects a loss of communications with the IPC. When the fuel level is less than 4 percent, the Low Fuel Indicator illuminates.
