Air Injection System Incorrect Flow Detected
I've never come across a P0000 code before, so I have no idea what that signifies. It may be a Ford indication that the P0411 is the only code, as if it is placed at the end of any "list" of codes in the ECU so that you know that you've seen every code currently failing.
Secondary air injection failures can indicate a failure of a secondary air pump, or could be as simple as a vacuum leak. Take some time under the hood and inspect all the vacuum lines - see if any are hanging free or unplugged, cracked, split, or broken. That can lead to failures such as what you're seeing.
