The fuel shutoff valve is a solenoid valve that opens or blocks the fuel supply. On diesel engines it is usually closed without current, so that the engine stops reliably when switched off. The engine control module energises it to let fuel flow and monitors its control circuit continuously. P0007 means the voltage in the control circuit stays too high, because the control module expects the line to be pulled to ground. Typical causes are a short to battery voltage or, with ground-side switching, an open circuit. The valve cannot be switched, which leads to starting problems or stalling.
Likely causes
Control wire open or shorted to battery voltage
Valve coil open
Connector fault at the valve
Output driver in the engine control module faulty
Symptoms
- Check engine light on
- Hard starting or no start
- Engine stalls
