Code P0401 - EGR

So my 13' has a issue at 76k on the clock. I keep getting the code for insufficient EGR flow. From what I'm seeing that is most likely a plugged cooler. Anything else I should check before swapping out that cooler?

Also, any comments on a Ford OEM part vs the likes of Dormane or Cardone? This **** is expensive so if a aftermarket is up to the task I'll consider it.

Up to now its been a couple exhaust bolts, get sensors and a confused DEF level that the dealer reset.

For those who might ask, I get to sit in a lot of stop n go traffic in northern nj. 25 minute drives frequently take a hour. Or more.

Clogged EGR coolers are pretty common on these trucks, depending on usage. The good news is they're not terribly difficult to replace, nor are they expensive to purchase OEM. This, I believe is the very reason the secondary cooling system no longer passes through the EGR cooler on 2015 and newer model years.

Got a really quick question for you most people post this code just curious how many engine hours do you have versus engine idle hours you can find this in your screen just curious to see my last truck was a 2016 head over 2000 engine hours and only 145 idle hours it was spotless inside when they took the motor apart thanks and sorry for your problem

I would say you need to stick with an OEM cooler should that be the problem. The aftermarket has it's place, but definitely not for replacement engine parts on newer diesel trucks. The quality of the parts is usually just not up to par.

radium - I'm not sure of the exact number of hours. What I can say is that I sit in a lot of stop and go traffic every day. Its well over half my daily drive time. Can't image that is good for it. I can say that I don't let the truck sit and idle much.

Justin - Thank you for your input on the parts. I had one of your tuners on my old 7.3 and it was a great product. I'd recommend DP any time and would turn to you again except the 6.7 already has so much power. Of course the trans could shift better.

Thank you all

No problem.

Yes, we tune the 6.7L's now too. We even offer a Trans Only tune for guys like you who are happy with the engine power, but not with how the trans acts.

Thought I'd come back with the final story. Took the truck into our local trusted shop. Sure enough, plugged EGR cooler and the EGR valved was loaded too. Odd, he said the carbon was kind of wet but he couldn't find any sign of a leak etc. At any rate its back on the road running great. Thanks for all the advice.

There are alot of vids on Youtube about this. Diesel Tech Ron, and FLMMAZ both had great videos showing removal/teardown/re-install. Might check them out.

Not sure if these will help. These first two don't really show removing bolts etc to remove, more of what it looks like when out.



This one shows what one person did on youtube to delete his EGR. Probably more of what you are looking for:
