What does P0001 code mean?
Fuel Volume Control Regulator Circuit/Open
Code P0001 stands for Fuel Volume Control Regulator Circuit/Open. Some diesel engines use what’s called a common rail fuel injection system. With this design, all the pressure the fuel injectors need is created by an engine-driven injection pump.
What does it mean fuel volume regulator control circuit open?
– P0001 : “Fuel Volume Regulator Control Circuit – Open”. It’s job is to increase the fuel pressure for the very high pressure needed at the fuel rail for the injectors. These high pressure fuel pumps have a low pressure side and high pressure side, and a fuel volume regulator which controls the pressure.
How do I fix code P0004?
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 does engine code P0004 mean?
Fuel Volume Regulator Control Circuit High
OBD-II Code P0004 is defined as a Fuel Volume Regulator Control Circuit High. The Fuel Volume Regulator allows the fuel system to release excessive fuel from the engine back to the fuel tank.
What does the Diagnostic Code p0001 stand for?
OBD-II code P0001 is a generic diagnostic trouble code (DTC) related to a potential malfunction with your vehicle’s fuel regulator control valve or its circuit system. What does the P0001 Code Mean? Diagnostic trouble code P0001 stands for “Fuel Volume Regulator Control Circuit/Open.”
What causes the fuel volume regulator code p0001?
The ECM regulates your fuel pressure from your fuel pump going to your engine through this circuit. When the computer detects a fault in the circuit, it will set a Check Engine Light. The code will affect fuel economy and possibly damage the engine. What causes the P0001 code? The fuel volume regulator code may have several causes:
When does a PCM trigger a p0001 code?
Once the PCM detects a fault, particularly an open in the FCVC or its circuit, it will trigger code P0001. On common rail fuel injection systems, the pressure needed by the fuel injector comes from an engine-driven injection pump.
What to do if your car has a p0001 trouble code?
P0001 is properly diagnosed with a scan tool capable of sensor readings (not just one from an auto parts store). A qualified technician can read the data from the scan tool to determine when the problem occurred, or if it is still occurring. They may clear the code/light and test drive the vehicle while monitoring data to see if it returns.
