More than likely a faulty valve.

That is an insufficient flow code. there are 2 common causes of that. The first is the passage that goes through the throttle body getting plugged up with carbon. You would usually have to remove the throttle body and clean the passage with a coathanger.
Another common cause of that on Fords is a bad DPFE sensor, also called an EGR pressure transducer.
