Where is the fuel volume regulator control circuit located?
What the P0001 code means. P0001 is the OBD-II generic code describing an issue with the circuit which runs from your engine computer (ECM) to your fuel pressure regulator on your fuel injection rail on your engine. The ECM regulates your fuel pressure from your fuel pump going to your engine through this circuit.
What is fuel volume regulator control circuit open mean?
Diagnostic trouble code P0001 stands for “Fuel Volume Regulator Control Circuit/Open.” Although P0001 is a generic code, it can pop up on various makes and models. This code indicates that your vehicle’s primary computer or PCM has detected a potential open in the fuel volume control valve (FVCV) circuit.
How do you fix a high fuel volume regulator control circuit?
What repairs can fix the P0004 code?
- Connect a professional scan tool to verify the code exists.
- Perform research from professional sources for testing and values based upon the code.
- Check for any other fault codes which may be related to the issue.
- Perhaps clear the fault codes to see which fault codes return.
What is fuel volume?
Testing fuel volume Volume is how much fuel we deliver in a specific period. For example, consider a fuel pump that produces one-pint of flow per minute. If the fuel injectors require one-half pint of fuel per minute at an idle, the pump can supply this.
How do you calculate fuel volume?
If you’re curious about your fuel tank capacity, here is a simple formula to determine the size of your gas tank in gallons. Simply multiply the length, width, and height (L x W x H) of the gas tank, then divide the total by 231. 231 is the number of cubic inches in one gallon of gasoline.
Where is the fuel volume control valve located?
The fuel volume control valve (FVCV) is found on high pressure pump on most modern common rail diesel engines. It regulates the volume of fuel from the internal transfer pump to the high pressure pumping components. The valve adjusts the low pressure side of the system to meet the demands of the engine.
What causes a fuel volume regulator to be open?
An electrical fault such as an open circuit in the fuel volume regulator on a system with a normally closed valve will also cause this situation. A short circuit on the control wire of a normally open fuel volume regulator will also cause this fault.
How can I Fix my fuel volume regulator code p0001?
How do I fix code P0001? Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Where is the fvcv located on a diesel engine?
The high pressure side varies according to injection type, but typically consists of a high pressure pump and fuel rail. The fuel volume control valve (FVCV) is found on high pressure pump on most modern common rail diesel engines. It regulates the volume of fuel from the internal transfer pump to the high pressure pumping components.
