these vehicles as well as every other Ford vehicle has had problems with the DPFE sensors going bad. Ford had a program for this problem but was limited to time and mileage. You can contact a dealer to see if it still qualifies if not the sensor will need replacement. this is very easy to replace

It is located on the right front valve cover area. It will be either black or silver and have a 3 wire connector with wire colors BN/WH,GY/RD,BN/LG. It will have 2 rubber hoses going from it and connecting to two metal tubes which run to the exhaust.
Now what sets the the P1405 is.
While driving, the EGR monitor commands the EGR valve closed and checks the differential pressure across the EGR orifice. The test fails when the signal from the DPF EGR sensor indicates EGR flow is in the negative direction. Make sure both of the hoses are hooked up and not damaged.
P0401 sets when:
The EGR system is monitored during steady state driving conditions while the EGR is commanded on. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum.
So the DPFE could be causing both codes.
I would also recommend that you take a hand vacuum pump and pump vacuum on the EGR while engine is running and make sure you have a drop in RPM so you know that the EGR ports are not stopped up,they are bad about this too.
As far as the rattling converters this could possibly have an effect because it does use exhaust back-pressure along with vacuum to help open the EGR but if the exhaust is still basically stock this probably won't have enough effect on the back pressure to cause this unless they have stopped up and have so much back pressure it is blowing the hoses off of the DPFE or getting so hot it melts them. You can check this with a vacuum/pressure gage, just hook it into one of the hoses from the DPFE and you should have 1 PSI at idle and 3 to 4 PSI at wide open throttle. Anything more would be a restriction.
If all of this is ok then replace the DPFE.

check the metal line that comes off the exhaust and make sure it isnt plugged with carbon. also remove the egr and check the port and see it's clogged as well

vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Also remove carbon built up behind the EGR valve and the EGR passage tube.
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.
