An EGR code can be caused by several different issues. One of the more common is a failing DPFE sensor. This sensor monitors EGR gas flow. There is a technical service bulletin put out by Ford with a recommendation for it's replacement for EGR related codes.
The code can be caused by a dirty EGR valve and port, a bad DPFE sensor, a bad EGR, bad vacuum lines, and bad wires/connections.
Check all the vacuum lines, electrical wires, and connections. Next remove the EGR and clean it and it's port. You can reset the code and see if it comes back. If it returns I would test/replace the DPFE sensor.
Good luck and let us know. :)
