Fuel Gage: Diesel
WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
The fuel gage displays the fuel level as determined by the fuel sender buffer module. The IPC receives a direct hardwire input from the fuel sender buffer module indicating the fuel level percent. The fuel gage defaults to empty if the fuel sender buffer module detects a malfunction in the fuel level circuit.
