P0005: Fuel Shutoff Valve A Control Circuit/Open
Do not keep driving
If the engine will not shut off with the key, do not ignore it — have the vehicle recovered rather than driven. Otherwise expect a no-start.
What this code means
The fuel shutoff valve is what stops a compression-ignition engine — cutting fuel is the only way to shut a diesel down. An open circuit here means the module cannot command that valve. The practical consequences run in both directions: the engine may refuse to start because the valve never opens, or in the worst case may refuse to stop.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
