Hi there:

A code P0001 which is for a Fuel Regulator Circuit, is for a diesel engine; a gas engine does not have an electrically controlled regulator, thus this code does not apply to this vehicle. I would suggest taking it to a parts store, for a second opinion.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
