P0005

Diagnostic Trouble Code (DTC) stands for "Fuel Shutoff Valve 'A' Control Circuit/Open" . It is a rare generic code triggered when your car's computer—the Engine Control Module (ECM)—detects an electrical break or "open" in the circuit that operates the fuel shutoff solenoid. This solenoid is responsible for stopping the flow of fuel when the ignition is turned off or in emergency situations. Understanding the Significance

When this code is stored, you will likely notice the immediately. Other symptoms include:

While standardized as a powertrain code, P0005 is seldom seen in modern gasoline vehicles because their electronic fuel injectors typically handle fuel shutoff. However, it is more commonly found in older diesel engines, such as the Ford Powerstroke 6.0L and 6.4L, or vehicles with dedicated fuel shutoff solenoids intended to prevent "dieseling" or engine run-on.
