Fuel Level

The Instrument Panel Cluster (IPC) reads the fuel level directly over a discrete input from the fuel level sender. The raw fuel level data is filtered for gauge display purposes. The IPC has two filter modes. A slow (heavy) filter is used whenever the vehicle is out of Park to prevent fuel slosh from activating the gauge display. A fast (light) filter is used whenever the vehicle is in Park allowing the gauge display to respond quickly when the vehicle is being fueled. The IPC also sends raw fuel level data to the Powertrain Control Module (PCM) via Class 2 serial data bus.
