Fuel Volume Regulator A Control Circuit/Open
This code means that the car's computer is having trouble controlling the amount of fuel that goes to the engine. It's like when a faucet is stuck and you can't control how much water comes out.
The code P0001 indicates an issue with the electrical circuit that controls the fuel volume regulator, which manages the amount of fuel sent to the engine.
P0001 is triggered when the Engine Control Module (ECM) detects an open circuit in the fuel volume regulator A control circuit. This regulator is responsible for adjusting the fuel pressure and volume sent to the fuel injectors. An open circuit means there is a break in the electrical path, preventing proper control.
• Use an OBD-II scanner to confirm the code.
• Inspect the fuel volume regulator and its wiring for damage.
• Test the fuel volume regulator with a multimeter.
• Replace or repair damaged wiring or connectors.
• Replace the fuel volume regulator.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Sensor Issue
• Avoid driving long distances until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer for warranty coverage on fuel system components.
P0001 is a relatively common code that has been reported across various makes and models, often related to electrical issues in the fuel system.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with a malfunctioning fuel system can lead to increased emissions and potential safety hazards.
• Engine running
• Fuel system pressurized
The fuel volume regulator is typically located near the fuel rail or fuel pump assembly.
Q: Can I drive with a P0001 code?
A: It's not recommended to drive for long distances with this code, as it can lead to poor engine performance and potential safety issues.
Q: How do I reset the P0001 code?
A: You can reset the code using an OBD-II scanner, but it's important to fix the underlying issue first to prevent it from returning.
