Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

replace the vsv that has the vacuuum hose running from it to the egr valve
SOURCE: p0405 code.. changed egr valve and cleaned passage
The truck has two egr vales unless it's a 4 cylinder, then it has one, if it say your slipping and it's automatic change the filter and oil in the transmission and add Lucas transmission fluid conditioner to the tyranny. If the EGR valve is still giving a code then it means something in the egr system is not working, and one item that comes to mind is the purge canister valve on the evaporative control canister. To test find the purge valve and crimp it off with a pair of vise grips to close the vent then drive it. If it runs good then you have found your problem. Also low vacuum can cause the transmission not to shift correctly as it needs a vac. input for it to shift. Check your transmission fluid if it is brown and sort of smells like onions then the fluid is burnt and will cause all types of erratic behavior. And since I took the time to write this I would like to get some feed back as I am about to stop doing this.

You have to the EGR valve (sometimes the Intake manifold to EGR Vlalve line also). After you remove it take a drill bit the about 20 % smaller than the actual hole of the outlet side and rotate the drill bit with your hand to dig out the carbon. Aditionally the line coming from the intake manifold to the EGR valve will clog near the connection to the EGR valve. I use either a single piece of copper wire or the wire that you would use to tie ribar together to clean the line. When your done cleaning take a piece of vacuum line and connect it to the diaphram side and **** on it... then plug the line well with your thumb. Grasp the valve and blow thru it... Air should blow thru it freely. Remove your thumb from the vacuum line and try blowing again.. No air should pass thru the valve.
Then reinstall the valve and start the vehicle with the vacuum line disconnected (but blocked off) Use another piece of vacuum line connected to the diaphram again and **** on the line.. The vehicle should die or run really bad. If it does this then you cleaned it correctly.
