Thanks for the video, found mine completely clogged, removed and replaced it with a new one and that cleared the "P0402 excusive EGT flow detected". Cleaned up the old one for a backup if it clogs up again.
Thank you for the great video. My MAP sensor was very dirty, just like what you had. I have a 2019 F250 Diesel and it would hesitate when taking off on a cold engine. After cleaning the MAP sensor, I tested the truck again and no codes and the turbo would pick up right away with no hesitation. I had changed the air filter prior to cleaning the MAP sensor and that did not help.
You are the man!!! I installed a new Perfomance intake on and it must have pushed a bunch of carbon through or because it’s got 70k on it it just got nasty. It was completely plugged. Cleaned it and the check engine light went right off!! Can’t thank you enough
I HAVE A 2017 F350 6.7 WITH 7,000KM. BASICALY 4 THOUSAND MILES AND HAVE A CODE P0402. HAD IT AT THE SHOP 3 TIMES NOW FOR THIS CODE AND IT KEEPS COMING BACK ON. DON'T KNOW WHAT THE PROBLEM IS BUT IT DOES NOT GO IN LIMP MODE . GOING BACK TO MY DEALER AGAIN FOR THE SAME REPAIR.
Pulled off my MAP sensor and it was completely clogged, now to test to see if code clears. Was getting code P0402, i will update to see if this clears the issue.
Hey awesome videos it helps us Ford owners..... I have a 2016 F250 diesel and I just received this code do you have any videos on this or what do you recommend.... P0401 Thank you! Arthur
Hello. I have the same issue and same code on my 2017 F350 with 147k miles. Replaced the MAP sensor and also the EGR. Not real sure what to do at this point. I only get the problem when I put my travel trailer on it and under a load. Any help would be greatly appreciated.
same code on my 19 with 75k miles. They replaced two sensors and still came back. get yours figured out yet? Do you have reduced engine power when light comes on?
@@giligan6534 I have a 2019 getting the same code replace the map sensor but still getting the code and reduced power. It only does it under load pulling my trailer. Did you figure yours out, what was the problem?
@@oldmanbck REPLYnever did figure out what it was. Put a tuner on it and took it to the local truck pull. never came back after that LOL. but I suspect a partially blocked dpf. anyway I’m in a 22 now and love it

Anyone know any more info I turn the light off truck still has Lack of power until I turn off the truck and turn it back on then it runs fine for about 50 miles and light comes back on I have to repeat the process
@@jessew9867same damn issue with a ford mustang! It's really pissing me off! Off on clears issue then about 30 to 50 miles does same shit! I've stripped entire top end and head gaskets. New mass air flow All I can think is the upper intake plenum is clogged
@@blautomotive7230 I have the P0402 code. 2015 f350. I haven't towed anything heavy since bought in 17. Already had to replace heater. I really don't get to drive long distances often. I used to run 900 miles couple at least a couple times a month. So alot of my driving is
Cleaned map sensor with a little brake cleaner. Let dry in sun all day. Put back in. Took drive, noticed lack of power. Noticed turbo pegged at 4. Turn off/on same. Was going to have friend who is fleet mechanic, look at later, but he says had a t least 2 that were map sensor. Bought new for $82. Turbo back down to zero instantly. Power is back, codes went away after several drives. All good.
@@blautomotive7230 thanks, I had a situation where, Driving down 275 I gunned it and noticed when I got home that the OEM turbo Guage was stuck in the 40psi position. Turbo sounded differently but I turned off the truck. Waited about 20 min turned back on and everything seems normal. My question, what can cause this to happen,l? The plastic intake on the top being clogged? The MAP sensor being bad? Just would like to know if there is anything I could do to fix it on my own. Thanks again.
Thanks! This video literally just saved me money. No CEL anymore!

Would running sea foam cause this code come on? I just added a can in my tank and now getting codes p0170 & p0402
What helped your truck with these two codes?
I have the same code what was the cause.
It was a dirty MAP sensor for this situation.
