Fuel Gauge

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. If the fuel tank is less than 1/16 full the PCM sends a class 2 message to the IPC in order to turn on the CHECK GAGES indicator. Refer to Fuel System Description in Computers and Controls Systems 3.8L or to Fuel System Description in Computers and Controls Systems - 5.7L for more information.
