Fuel Gage

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

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 E (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 fuel level is less than a pre-determined value, the DIC displays the LOW FUEL message.
