Ok here is the solution when I had the exact same problem with my 2001 Ford Escape:
Idler air control valve
EGR vaccum sylenoid
I did all of this work myself (and as a girl it was not hard at all), it cost me around $170.00 for all of the parts, had it done in less than 2 hrs., erased the codes and have not had a problem since then! I hope this helps you out, cuz it sure would have helped me out when I encountered the same problem.

This might sound crazy but it works with these Escapes most of the time. Go buy a can of Seafoam from your part store. With the engine off, disconnect the brake booster vacuum line and place it in the can of sea foam. Start your engine and keep your foot on the gas pedal and keep the RPM's around 2k.The vehicle is going to smoke like crazy for 10 minutes or so, when the smoke clears up for the most part, go drive it for a couple of miles and see if that helps. It cleans out the carbon buildup from you intake and sensors and takes care of that code you getting most of the time. OR, you purge canister needs to be replaced...

The code in the ECU might not have reset after you changed the EGR. Try unhooking the battery and let the car sit for a couple minutes and then hook it back up and see if the light goes away.

P0401 shows an Exhaust Gas Recirculation Flow Insufficient. Without a good scan-tool you will be playing the "Parts Changing Game". Insufficient flow can be the result of a vacuum leak, bad MAP sensor, an exhaust leak, faulty EBP sensor, carbon build-up, and so on. I wish I could say more but with all the electronics it is more complicated then earlier cars.
