Fuel Gauge: Description and Operation

FUEL GAGE

The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM)/powertrain control module (PCM). The IPC receives a class 2 message from the ECM/PCM indicating the fuel level percent. The fuel gage defaults to E (empty) if the ECM/PCM detects a malfunction in the fuel level sensor circuit. Refer to Fuel System Description for the 3.5L engine or Fuel System Description for the 3.6L engine.

When the fuel level is less than 11 percent (less than 1/16 tank) of a tank of gas, the LOW FUEL message illuminates in the message center.
