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 volume. 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 14%, the low fuel indicator illuminates.
