The P0001 is not a valid code for a 2011 Toyota Avalon. Can you re-check that code for me?

CODE COMES UP THE SAME EVERY TIME

Hello. Please allow me to assist in this request. I agree with my colleague that the code is invalid with the vehicle you specify. Additionally. The p0001 code is a "generic" code; this is usually displayed with a scanner that is either incompatible with your car or the scanner is faulty.
I would recommend another scan with a different scan tool. I doubt highly that the P0001 code will appear on a different scanner.
Additionally, this engine does not have a 'fuel volume regulator circuit' fitted. Toyota does not use such a device; that is why the code is not valid.
