location of EGR EVR

What is your question?

On my 2002 Windstar, the cannister purge valve is located where the EVR should be. I have been told that the EVR was moved in certain ones. Could you point me to that location and tell me what it looks like?

What makes this problem better or worse?

Error code P0401, insufficient air EGR flow. I'd like to check the EVR and the hoses.
