[@thenewpatriot737]

This video is for all my brothers out there in trades where troubleshooting nightmares have had us questioning our own, very existence in the universe😄. How much better would the world be if repair technicians where as transparent as you. You sir are a true class act. Wish you were near my area in So Cal. Your work ethic will shine out to the rest of the department which in turn will mold more great technicians. God Bless you sir! After my cold pipe blew, on replacement, I noticed a lot of soot build up in that area of the manifold which I tried cleaning as much as I could without letting too much fall in. I did not realize those were ports behind that round thing. I'll have to go back and check if they need cleaning. My truck was still idling a little rough and not much power after the pipe change out but the MIL reset. I found the MAP sensor to be clogged of soot as well and after cleaning it, the truck was running perfect again. Which leads me to my question: What causes the carbon to build up quicker in that area?

[@PowerStrokeTechTalkwARod]

By product of burning fossils fuels my friend.🙋‍♂️

[@carls2210]

This is why I need to find time to bring my truck up to you. You take pride in your work and care to show the bad with the good.

[@espweirdo]

When I did the disaster prevention kit, I could not believe how packed off both upper and lower intakes were... truck was immediately put on strict weight loss diet and ordered the Pusher piping kit.

[@anthonyb8691]

I’ve been to after treatment classes and a large majority of these codes stem for the engine side turbo egr etc these are all things that reduce nox etc I watch your video weekly I totally respect you for posting this most people would not I know how much pride you have in your work great video

[@PowerStrokeTechTalkwARod]

Appreciate that pal

[@Thegoose95]

I don’t know what it is, but for some reason after a repair, we can test drive and idle a truck for days and everything seems perfect. But as SOON as the customer turns on the damn thing…BOOM.. check engine light. Never. Fails.

[@wilwiener]

Been there done that.

[@Terror1Void]

I'm willing to bet you're not putting a load on it like the customer is. Our 15 Freightliners will do fine bobtail after emissions repairs and throw codes as soon as I hookup to a trailer.

[@Thegoose95]

@@Terror1Void yeah I never get the chance to hook a trailer on. And all box trucks, flatbeds, and garbage trucks come to us unloaded.

[@crewdawg2008]

@@Terror1Void Ya know, there's something to that. My wife wanted a Tahoe, we went to test drive one at a dealership, she really liked it, I rode along as she test drove it, all was fine, then I drove it myself, and I stood on the gas to really put it to work. Wouldn't you know it? Check engine light pops. It was an O2 sensor, dealership made the repair, then drove it again, and all was fine. Whether it matters or not, it's a used vehicle, but we went ahead and bought it and haven't had an issue since. It's just always important, in my mind, to put a vehicle through the paces and make sure it's all solid.

There is a great carbon/oil cleaning solvent that most Ram dealers have on the shelf because of the EGR cleaning requirements for them. Block off all holes and pour in the quart of the stuff and you will be rather surprised at how easy the carbon comes out. I wish I knew who actually made that product because it works so well and I hate giving a Ram dealership any of my money. I’m approaching 100K miles and removing the upper and lower intakes for cleaning is on my list of things to do. Also, the fact you’re sharing your own missed diagnosis and the pain you’ve gone through just proves how good you are as a tech. You were diligent and eventually found the culprit. Great job finding it and fixing it.

[@PowerStrokeTechTalkwARod]

Thanks so much buddy!

Dude that's why your the bestest tech out there ....staying with it .....lesson learned ....!!!!!

[@buckhorncortez]

Great job diagnosing a hidden problem. As my shop teacher always used to say, "We learn by doing" and that's the best you can do when the problem isn't obvious and the diagnostic instructions are generalized. That's why I take my trucks to the Ford store, their mechanics see and fix problems unique to the specific vehicle design.

[@PowerStrokeTechTalkwARod]

No doubt

[@rar91181]

Thats the first thing I look for on heavily idled trucks setting a p0401. Especially 15 and up. They don't seem to restrict EGR cooler cores like the 11-14's did.

Just one little tip on the death wobble, well 99% of the time it comes from the front end and usually the track bar would be the first thing changed but don’t ignore the leaf springs in the back, make sure they’re not broken, ask me how I know this.

[@gibrancubillas6297]

That the most important thing you do, not quick, that is i like ti see your videos, good job......

[@jasoncarlsen5138]

Yes I have in a 2015 f250 but never set a code for it. Was in for a drivability concern due to a bad torque converter but took the intake off to check for contamination of the fuel system and bam the intake was nearly plugged solid at 90k. Stick with your guns and don't read past the original code p0401 egr insufficient flow. Congrats on sticking with it and finding the solution.

[@PowerStrokeTechTalkwARod]

[@smtshrek3674]

Around here with all the high idle time the farmers and utility companies do we recommend cleaning upper and lower intakes and map sensor as preventative maintenance every 50k or if it’s in for 401/207f repairs. It’s like the 6.0 all over again, some people don’t agree but after you fight several different codes caused by carbon, fleet customers understand and pay to not have anymore down time

[@PowerStrokeTechTalkwARod]

Buddy ive never had this issue be4. I will never forget. Maybe this is something I will now implement

You preserved and fixed it... the modern diesel emissions and electrical systems are so intricate that even the best techs hit a wall occasionally and have to regroup and try again. I’m sure this will never happen again to you! Is the cleaning process of the 3 egr ports something you can do with the lower intake installed ? Once you found it you must have been so mad at yourself,I know I would have called myself every name in the book and a few of that weren’t In the book! Thanks you for sharing this diagnostic and repair procedure, im sure it will help someone.

Mind blowing! We have a fleet truck that i too replaced a egr cooler on for same code. P0401. And it occasionally still sets same code. We may have this exact problem. I was with you also and didn't feel confident on the cooler when i saw it. I too only checked up to the intake egr pipe. I never thought of checking lower intake. I will definitely be checking the lower intake now. Thanks. Keep up the good work!

Some times we can't see the forest for the tree, we do common sense trouble shooting and over look the obvious, I've done myself. With that being said I own a 2019 F350 SD 6.7 and the first time after 35K miles I removed my throttle body and found this god awful oily mess and cleaned it out never seen the like. After that I did the CCV REROUTE and then installed a 2020 model year intake manifold and picked up 2 to 3 mpg. And now there is only lite soot inside the manifold. Keep up the great work that you do, that's why we all look for your expert knowledge, your A number 1 in my book..

2017 f350 alumiduty 6.7l 150,000 miles, I had the rubber cold side intercooler pipe burst, when I replaced it with a metal one I had to clean a ton of that black crap out of that section behind the throttle body. I hadn't had any codes thrown.. yet. I bet I was well on my way to this problem though.

[@markkoppenhaver5366]

Thanks very much for this. I have a hard time diagnosing P20EE and P207F. The pinpoint tests don’t guide you to the root cause. I’ll check for these clogged ports from now on.

[@adamkamm6331]

Moved the cause of a 401 from the cooler to the intake with the redesign. Great information and thank you for sharing your struggles. Everyone has them. It's all about learning

[@tomcat1fl]

Hi ARod, I appreciate your work. I have a '16 F250 Platinum with the 6.7 in it. Have seen P207F quite a bit. Every time I take it in, the shop says the DPF was clogged, they say they do a region and charge 375 for labor and give it back. They replaced the DEF tank and pump assembly when I had a P207A at 65795 miles. I understand why the filter clogs frequently, I don't drive it long enough or far enough to get it to clean on its own. I got a copy of FORScan and learned to do my own regens. My problem today is I got into the 50 miles before 50MPH warning. I got it home and put it on FORScan and as expected I got P207F. I did a regen and cleared the P207F but the 50 miles to 50mph didn't clear. Truck has just over 85K on the odometer. I'm looking for 2 things e. 1) Where do I go to find the driving procedures to reset these warnings, I'm mechanically inclined but not a mechanic (used to work on my own stuff back in the 80s & 90s), and 2) is there a comprehensive pdf out there that I and an owner can use to troubleshoot? Is it possible that I have the issue in this video if the only code Ive gotten in the last three trips to the shop are P207F? Again, Thanks for all you do.

[@PowerStrokeTechTalkwARod]

Yes, you neeeeeed to go thru the proper pinpoint tests as you saw in the video. You can try motorcraft.com I have 2 videos that show you how to remove it from 50mph OR idle only. There are in my Playlist sections & need to be followed to a TEEEEE!!!!! or it won't work. P207F's suck btw....

[@comporangegt]

I have had several super duties with the 401 code and that port plugged with soot. I remove the upper intake and clean all the soot from that as well. I am currently working on one with a 20EE and I did the pinpoint test which lead me to replacing the NOX sensors and modules. Went for a test drive and as soon as the PM sensor went through regen I saw the DTC count turn on. The same code of course, I checked mode 6 and the EGRT12 was showing 17 degrees when EGRT11 was 68 degrees. I am going to replace that EGR temp sensor and see what happens after I drive it again.

[@orvillewilkerson5432]

Super job! I had a 2005 and three dealers gave it back to me telling me they could not fix it,, I was a egr by pass holes or something? and it was a recall at that! A student mechanic at a deal fixed it!

[@lanehammer]

This video was the reason why I purchased a pusher intake

[@bernietorres25]

Oh I know how that feels same thing with me excepting it was just a P20EE and I did the pint point test forward and backwards and even thought aliens had zapped the truck lol only to find something that was in plain sight but not taken as important as the the rest of the system parts are. One of the things I ask now and even check on the cluster is high idle hours, down here in Florida people love to sit in their a/c and carbon loves to attach to fresh naked metal, lol thanks for the video..

[@PowerStrokeTechTalkwARod]

See you in florida

[@CITIZENSDOGE]

I believe I had that 401 code. It turned out to be the manifold pressure sensor. It was plugged up with carbon. I’m pretty sure you already know where the manifold pressure sensor is. It’s easy to check in his right on top of the engine.

You’re right the intakes get nasty but I’ve too never seen them plugged up like that. I wander that’s due to the new cooler design being less restrictive?🤔

[@coreyfincham3417]

I had the same exact issue. A truck came in from another dealership. They replaced the egr valve and cooler 2-3 times and 401 was still setting. I checked the intake and found the same thing. I removed the lower intake and power washed it out. Truck hasn't been back. The truck had low miles but a ton of idle hours.

[@PowerStrokeTechTalkwARod]

Never will I forget

[@pepinillorick1214]

I have a 2014 right now, with 401,207f, and that scr dtc too. What i did so far is, Cleaned both intakes, replaced egr valve and cooler, had to replace the exhaust manifold because the inlet pipe bolt broke, (i don't own that kit to remove the broken bolt) replaced all one time used parts on that, cleared codes, drove it and right around the 25th mile truck goes on derate, and the only code that shows is p207f. Checked reductant quality following ppt rd. Right now i recommended the NOX sensors. Both are reading the same. ...is crazy how this video showed on my feed like it is literally what im dealing with right now. 😅

[@jmonty11b]

In my 2019 350 6.7l I've noticed if I forget to put it in Tow Mode before hauling my 15k lb RV it will trigger a P20EE. I'll clear it on my own and see if it comes back. It seems to come back for a few weeks and then it'll stop coming back until I forget tow mode again.

[@alexkoya4048]

Okay so I’ve ran into a similar situation and the customer denied the intake cleaning services and just wanted to do the egr valve replacement. When they brought it back with the same 401 code they tried to back-flag me luckily in my notes I put lower intake manifold severely restricted recommend upper and lower intake services. Showed that to my manager he called the customer. Customer approved intake cleaning and never saw the truck again… Ever since then any time that I have similar codes I inspect that lower I take and if I see any gummed up gunk in there then I give the customer the option to clean both intakes that way it is on them whether or not they want their vehicle repaired properly. Very easy to over look things like this especially when you have two codes from separate systems. Very nice work getting down to the bottom of it! Also I was wondering if there was any way that I could get that cheat sheet pdf for the 207f and 20ee codes?

[@darrenhenley6080]

I had the same issue with my 2014, except the code that popped on me was P2263 "Turbo/Super Charge Boost Performance. I had probably 80% blockage all the way around. I wish I could send a picture, it's amazing it would run at all.

[@PowerStrokeTechTalkwARod]

Thanks brotha!!

[@axl151]

I saw the mention of high idle time(=bad news for emissions equipped trucks), but find myself pondering if there might have been a small casting fault in that lower intake (a raised burr or slight restriction) that gave the carbon an initial place to start sticking to , creating the port blocking buildup.

[@pepelepew4117]

My thoughts as I watched were that it might be a good idea to do a little polishing around those ports to prevent the the problem returning.

[@TheRealSlowhand]

[@bryanfordreif]

I had similar on a 2017 transit 3.2 was chasing it for a week and the cooler was plugged but I didn't think too check the intake and there it was 207e .but the scr was bad that is why the Knox was the same

[@smtshrek3674]

My diag for 207f/ee is drive it watching pids, def psi should be 72psi and under 15% duty cycle, when the injector first starts it should blip the psi indicating it’s spraying and pump duty cycle staying around 15% indicates it’s no plugged. Once system is up to temp and working steady 65mph cruise nox 11 should be 200ppm and nox 12 0-10ppm. If nox12 is higher than nox 11 then 12 is bad. If nox 12 is elevated 80-150ppm it most usually is a def quality/injection fault. If 12 is close or mirroring 11 the scr is not working or is overwhelmed. Now if both are elevated, 11 is 800-1000ppm and 12 is 400-600 maybe even matching 11 then there’s an upstream issue with egr not being able to lower nox and overwhelming the scr, anything from a bad valve, plugged cooler, and plugged intake.

[@PowerStrokeTechTalkwARod]

Thank you screen shotting this mister!

[@williambourne5092]

I just had this problem did the nox sensors and modules and throttle body was so plugged up the butterfly wouldn’t even move but I didn’t check the 3 inlets behind the throttle body thought I had it fixed but came back two days later same codes as you pulled the egr cross over pipe and seen the cooler face plugged so I did the cooler and valve and gave it back and it came back I was ready to set it on fire so I got to thinking and check the ports like u did and they were plugged solid so I guess I’ll be pulling the lower intake on Monday to have it cleaned the only good thing is I work for a construction co and there our trucks so it’s not as bad as sending it back to a paying customer I just have to here the formens cry they need there truck I hope this is the fix if not the truck will go to Richie brothers auction 😂😂

I work at a ford dealership and I have a 2020 f250 customer complaint is check engine light p20ee nothing else. Nox11 efficiency. First thing I did was a regen regen saw soot loaded at 120% during regen I found an exhaust leak from rust hole in dpf system, after nox11 before scr. After regen I performed a def injection flow test. Clean spray pattern and perfect amount to specs. Sold a dpf and all 3 nox sensors and all 3 temp sensors. Installed road test 20 miles everything was good. Customer picked it up, brought it back next day for p20ee again. This time I cleared the codes and road tested while watching mode 6 and nox 11 would fail every 8 miles. I checked for failed ccv, none. Air filter? Dirty put a new one in. Boost leak? None. Egr valve operation? Perfect. Egr cooler is cooling. Map and maf I replaced just for the hell of it. I checked egr port behind throttle body clog free. I did everything the pinpoint test said and it passes everything but still get a p20ee every 8 miles. I don't remember what nox 11 reads while driving but at 80mph nox 12 is reading 0ppm sometimes will rise with heavy acceleration but never as high as nox11. This is a rental f250 from New York so I'm sure it a gets short drives all the time. Hints to why the intake manifold was full of carbon build up really bad for the low miles. 30k miles

My truck is going through the same problem and the same amount of miles

[@matthewfort3740]

Wow a lesson learned for sure. When I did my disaster kit. I noticed my lower intake was nasty. About 1/ 4 to 1/2 inch of crud. So too it to the solvent tank and tried to clean. It was bake in hard. So power purple and soke it in a bucket. Scrub like heck and it was spot less. But thinking about it when I changed out my egr cooler. I was thinking it really didn't look that bad. So maybe my 401 was the lower intake?. Good to know to check if it happens again Arod. Thanks for the info. And keep plugging away.

[@agmechanic94]

Seeing this truck is a service truck and being a field tech myself I can imagine high idle time had a major effect on this issue. Oddly enough the same situation happened to my coworkers service truck, 2019 F450 had in the neighborhood of 42,000 miles and around 4500 idle hours. Took 7 trips to the dealer to get it figured out till they replaced the lower manifold. Knowing the issue he had then I stumbled upon a video on an identical situation is crazy to me. As a fellow tech great job and perseverance!!!

[@PowerStrokeTechTalkwARod]

Thx brotha

[@Frank-pv1hp]

We don't work on many diesels in our shop. On a gas engine, you can tell if the EGR port or passages are restricted by opening the EGR valve and seeing if it stalls the engine or at least makes it run very poorly. Same on the diesels I'm assuming?

[@PowerStrokeTechTalkwARod]

Sorta

[@BAfrom1996]

Just bought a used 2017 f250 with the 6.7. I’ll be going back to the dealership for the FOURTH time for a 20ee code this week. I’ll be sure to show them this video

[@PowerStrokeTechTalkwARod]

I will NEVER miss it again. I learned on this one, good luck buddy! Let me knw

[@johnnyrizzo8057]

Your a freeken maniac. Great job. That throttle body was nasty. Think whats heading into the turbo. Heading for a weight loss plan next.

[@Alignmentguy]

Cleaned mine out with a scraper and a vacuum. Has since been removed permanently. No more throttle valve or EGR to contend with.

[@RXR91]

This is good stuff. Learn from failers.

[@ck3561]

Do you think fuel additives and being mindful of your idle time could prevent this?

[@PowerStrokeTechTalkwARod]

Yepp all day

[@jasonwember9927]

You put a scr in with a p0401 code... Egr is there to reduce nox formation in the combustion chamber. But i get it, it happens to the best of us. We're all human.

[@PowerStrokeTechTalkwARod]

SCR for 401...no...replaced 9V425 for that.......watch again budd🙋‍♂️

[@jasonwember9927]

I know you didnt change the scr because of the 401 code. What i meant was I wouldnt have replaced the scr until I knew the egr system was fixed first.

[@dashcam5398]

So how to repair this , does the intake come off or can you just clean while still installed on the truck. If you can clean it on the truck I would just pull the pipe off once a year and check and clean as preventive maintenance .

[@PowerStrokeTechTalkwARod]

Gotta take it off

[@stevenfuchs2548]

Wow, not to long ago I was changing the CAC tubes and removed the TB on my 14. Uggggllllyyy. I cleaned as much of the black gueies as I could. Then I looked in the black hole and cleaned as much as I could there also. Had no idea there are ports in there. How did you clean them? That would be, in my opinion, the next important question! How, how, how????? Great video!

Long skinny screw driver & my kick ass air vacuum

[@jimanderson2518]

Wow I'll have to say Your a pretty up standing guy..... Good parents ...got to be eh??? I have a P 207F no other codes brand new FLUID ...The system indicates the system level is full The computer still reads 66km til reduction in power ... Any thoughts from some one would be nice Cheers 🍻

Thank you sir yes I wish they were still alive You may want to get the system To do a refill activation with a scan tool

[@PowerStrokeTechTalkwARod]

Come thru!

[@davidayers6758]

Been there done that I’m a double senior master and have had the same problems and it sucks 207f has to be the worse code to diagnose I’ve seen the same issue with the lower intake being plugged I’ve also found excessive oil being pulled through the ccv into the front of turbo saturating all the soot throughout the engine and cause the 207 f try and get all that cleaned out, yea buddy let me just tell ya!

[@PowerStrokeTechTalkwARod]

Thanks pal

[@silntklr]

That is crazy, way to keep at it ARod!

[@caspian5578]

I’ve had a p0401 and found a very carbon filled lower intake. Replaced the cooler and cleaned the intake alright. Never a 20ee or a 207f…yet

[@caspian5578]

And doesn’t 207f ppt say diag other codes first?

[@shawngates138]

I have the same propblem on a customers truck I'll check it thanks so mutch

[@smtshrek3674]

I don’t know we’re you got that pdf but upstream components can definitely cause 207f and 20ee. Scr lowers nox but what else does? EGR! If egr fails scr will get overwhelmed. I have definitely seen that plugged up intake cause all kinds of dtcs including 207f and 401 that other guys already threw egr valves and coolers at it.

[@PowerStrokeTechTalkwARod]

Yea she got me

Thank you so much for sharing that with everybody.

No problem here.# deleted, 2013 180000 miles. Thanks for the videos.

[@joshuadomingo9875]

Working on a local municipal fleet that have high idle, they constantly burn through EGR Valves, Turbos, CCV Filters, Reductant Units, clogging the upper intake, eating the Throttle body, blowing CAC hoses, so many issues

[@PowerStrokeTechTalkwARod]

I thought i saw bout everything until then 😔😔😔

[@joshuadomingo9875]

@@PowerStrokeTechTalkwARod I just wrapped up another truck today, I don't remember what the codes were but it was stuck in forced derate, wouldn't regen, and oil consumption. 10 hours of diag, found EGR valve actuator was stuck closed, CCV filter clogged, 9th injector was stuck, NOx Sensor was biased, CACT sensor went out, MAP sensor clogged to hell, throttle body was clogged, and Turbo seal leaking. This truck was one their fleets loaners that sits for ever until someone needs it and they never bring it in for maintenance.

[@joshuadomingo9875]

Total repair was new turbo seal, NOx Sensor, lower CAC hose, CCV filter, EGR Valve, throttle body service, new upper intake and MAP sensor, cleaned lower intake, new dosing injector, and an exhaust manifold because the bolt for the EGR inlet broke off in the manifold lol. And Monday I get to test drive and do a couple regens because DPF load was at 103%. But ong the engineers that designed the new 6.7 deserve a swift kick to the nuts. Trying to take those turbo inlets off were a royal pain

Thanku

[@dieseldrjustin3857]

I have never seen a 17+ with 207f but don’t feel too bad I have a 19 that has been back 3-4 times now for p20EE and went through an replaced everything you did other then the scr. Was told trucks comming back but havnt seen yet, but good video I would have never thought to check the intake egr ports behind that valve. Also never seen 17+ w/ a 401 only a few 402s.
