Astro Van 2WD V6-4.3L VIN X (2002)
Fuel Gauge: Description and Operation
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel
gage defaults to empty if:
^
The PCM detects a malfunction in the fuel level sensor circuit.
^
The IPC detects a loss of class 2 communications with the PCM.
When the IPC detects that the fuel level is less than 17 percent, the IPC illuminates the low fuel indicator.
