EGR Troubles:
"Insufficient EGR flow"Possible causes: Clogged EGR passages in the manifold gooseneck
Bad EGR valve
Bad DPFE sensor
Bad EGR Vacuum Control Valve
Clogged edge orifice in EGR pipe (very unlikely)
Here's a primer on EGR: http://www.lincolnsonline.com/tech/00217.html
The best bet for the trouble is cause #1. Next best bet cause #3.

Insufficient EGR Flow
Recommend cleaning EGR.
If cleaning the EGR valve and orafice(s) doesn't do the trick, then you're looking at a bad DPFE sensor. Common code and common cause.
Oops, Kattumaran you beat me do it.

I have a 02, had this code years back, Ford had issues with DPFE, suggest using only a new Ford replacement to avoid purchasing the junk that ford had trouble with. In the future its a good idea to put up the year and engine.

Another Good Source:
Reasonable advice, Bill, but be apprised that BWD, an American outfit would you believe, produces excellent quality aftermarket products that it retails through Advance Autoparts. My ride sports a replacement TPS and a DPFE sensor by BWD; they work perfectly and are quite reasonably priced.
