Fuel Gauge

The IPC  sends a reference voltage to the fuel level senders. As the fuel level changes, a separate float on each sender actuates the variable resistor fuel level senders, raising or lowering the fuel level signal voltages. The IPC  monitors the changes in voltage from both senders and commands the fuel gauge with a corresponding movement of the pointer.

Depending on which operating mode the fuel gauge is in after a fuel fill up, the time for the fuel gauge to move from empty (E) to full (F) ranges from 2 seconds to 55 minutes.

The IPC  uses 4 different operating modes to calculate the fuel level:
