Fuel Gauge
The fuel gauge is controlled by the PCM. The PCM monitors the fuel level sensor and sends the Class 2 information to the instrument cluster through circuit 1036. The fuel gauge displays the fuel level based on the Class 2 information it receives from the PCM.When the fuel level sensor reads the fuel level at less than 1/16 full, the PCM sends a Class 2 message to the instrument cluster through circuit 1036 to turn on the check gauges indicator.
