My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Code P0004 usually indicates fuel volume regulator control circuit high.This can be an issue with the fuel volume regulator itself causing this fault here in some cases.The code needs to be tested/diagnosed to help pinpoint and repair this fault here and then repaired from there.If you need more info on this code let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

If you have not checked for fault codes using a scan tool that can plug in and communicate with all computers in your model at all this needs done.Some of the cheaper hand held scan tools are only able to communicate with the engine/transmission computer to diagnose any codes set in this computer and cannot read anti lock brake codes or traction codes.

I would have the codes re checked with a fully compatible scan tool to see if any other codes are set needing diagnosed and repaired to correct this fault here.

Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.

Thanks Pete
