CEL Light, EGR FLOW?? Please Help!

[Blinkstang]

Hey guys, my buddy has a 2001 V6, all stock. His CEL light just came on yesterday, so I had him run the code at Autozone, it came back:

P0401 Insufficient EGR Flow

Does this just mean he has a dirty EGR valve?? Should he pick up a new one?

Or am I way off, and its something else?

Also, where is the EGR located on the six, I have a GT so I wasn't sure.

Thanks for the help!

(I know I should have posted this in the V6 tech, but I am use to posting in here, and I figured it wasn't really an engine specific problem)

most of the time its a dpfe sensor that causes that code, i would hold off on the egr valve and check into that sensor first. the sensor has two vacuum tubes that go to it and an electrical harness that plugs into it. its a small black or alum. box. hope this helps
