What does it mean?
The fuel shut off solenoid is used to shut off the fuel supply to the fuel pump. It is typically controlled by the starter via a relay. When the ignition is off, the spring loaded plunger is in the down position, blocking fuel flow to the pump. When the starter is cranked, power is applied to the solenoid from the shut off relay. The plunger is then moved to up position, allowing fuel delivery to the pump.
When the ignition switch is released and the engine is running, low amperage current is applied to another winding on the solenoid to keep it in the up position. An example of a fuel shutoff valve control circuit Code P0005 stands for fuel shutoff valve control circuit open and indicates a problem with the shut off solenoid or its circuit. Note: Circuit Open means that a component or sensor in a system is deprived of the reference voltage it needs to work.
Causes of open circuits are many and varied, but for the most part, this type of code is caused by broken wiring, poor connections across electrical connectors or previously repaired wiring, loss of ground that prevents current flow, blown fuses, defective relays, faulty switches, or any of a host of other issues and problems that prevents the flow of current through wiring.
