The engine is shut down. The fuel metering valve is an electronic gas valve that controls the flow of fuel to the engine. The valve works with the engine ECM in order to ensure the correct flow of gas in all conditions of engine operation.The ECM sends the desired fuel flow and specific gravity of the gas to the fuel metering valve. The valve converts the command signal and the information into a valve position that directly corresponds to the desired gas flow. The position of the valve is compensated by these additional factors that are internal to the valve: .
A signal for absolute fuel pressure
Differential pressure across the valve
Fuel temperature sensorsCommunicationsThe ECM sends the following information to the fuel metering valve via the CAN data link:
The specific gravity of the fuel
PWM signal for desired fuel flowThe fuel metering valve sends the following information to the ECM via the CAN data link:
Position of the fuel valve
Absolute fuel pressure
Differential pressure across the valve
Fuel temperatureIf the ECM and the fuel metering valve cannot communicate via the CAN data link, a 1446-9 diagnostic code is activated. If the engine is running, the fuel metering valve will use the command signal from the PWM signal. The engine will continue to run. However, if the engine is not running and a 1446-9 diagnostic code becomes active, the ECM will not allow the engine to start.PWM SignalThe ECM sends the command signal for the fuel flow via a PWM signal. If the PWM signal for the flow of fuel is interrupted, a 1446-8 diagnostic code will be activated. The fuel metering valve will use the command signal for the fuel flow via the CAN data link.Pressure CodesCycle the battery power and ensure that the GSOV is operating properly. If the code remains and fuel is not present at the fuel metering valve, replace the fuel metering valve.

Thoroughly inspect the harness connectors for fuel metering valve (1). Also, thoroughly inspect the condition of connectors (2), (3), (4), (5), and (6). Check fuse (F5) for good repair. Ensure that the power connections that are for the terminal strip in the engine junction box are tight and free of corrosion. Refer to Troubleshooting, "Electrical Connectors - Inspect".
