What is your question?
When you scan for to see what the codes pop with 2 codes showing it has P0446 and the next code is P0446pd. unplugging battery will not reset it. What is the pd stand for behind the code.

P0446 = Evaporative emissions control system, vent control circuit malfunction. My guess on the P0446PD is since you already have a P0446 then the computer has another P0446 pending.

the manual with the scanner I have it is a mature code if it has pd behind the code
Good deal, I am glad you still have your scanner's manual for reference. :-)
