Fuel Gage

The ECM sends fuel level percent to the IPC via class 2. The IPC displays the fuel level as determined by the ECM. The IPC receives a class 2 message from the ECM indicating the fuel level percent. The fuel gage defaults to E (empty) if:

• The ECM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the ECM.

When the fuel level is less than 4%, the low fuel indicator illuminates. Refer to Evaporative Emission (EVAP) Control System Description in Engine Controls for more information.
