I’m subscribing to you because you’ve performed a miracle,you actually got a kid out of the house,off of the computer,the cell phone the PlayStation and the tv,talking to you instead of texting,omg that is a monumental task in these days and times that most parents wish they could accomplish.
I was getting my check engine light checked at auto zone, the first time they said it was the dpfi. Sensor. Put that on the same thing. Next the egr. Same thing. Next the vacuum solenoid. Still check engine light. So I saw your video, so I did what you said, no light. I recommend cleaning the ports before you do anything. I thank you very much for your video. If I would have seen it first I would have saved a couple hundred. Thanks
I'm glad the video helped you out. If your light comes back on check your two hoses to your egr. My hoses were slam full of gunk as well so I ended up replacing the hoses and never had another problem
Your daughter is adorable. Just finished intake gasket job trying to fix high LTFT (vac leak). There are NO vac leaks anywhere and now have the P0401 code along with high LTFT numbers. When I did have the manifold off, everything was coated with gunky oily shtuff. Also, while the engine idles, I can here a hiss that is no where to be found. Going outside to replace the EGR and then the solenoids if that doesn't do the trick. Little story behind my truck. It is a cheap CList junker that has me addicted to getting it back to perfect. No shop is going to touch this truck. Want to do it all by myself no matter how long it takes.
@@iamlazarow3526 YES....took my time and made sure all the Dorman gaskets were replaced clean & easy. She runs perfect with great fuel trim #'s. NOW I'm working on steering wheel play/slop.
@@iamlazarow3526 The intake gaskets & water cross over gaskets. With the Dorman intake off, I turned it upside down and filled it with water to see if it had a crack or leaked. Check to make sure it wasn't suck'n air that way. That vac leak was driving me mad I tell ya and it was going to get fix'd !
That's a good idea to clean the throttle system. Usually with older vehicles such as the F150 and/or Expeditions the EGR valve doesn't open all the way to allow fuel in. Chances are it'll run for a while then the code will possibly come up again. I simply replaced the valve itself and the control switch. One thing about the larger vehicles with vacuums and solenoids,,, you'll almost end up replacing the whole system due to the age of the vehicle.
I appreciate you making a video to try and help… however brake cleaner is too harsh for the throttle body. Use throttle body cleaner that is designed to protect the sensors and rubber or plastic apparatus that may be connected to the throttlebody assembly. thanks!
6:50 no wonder we always struggled changing the egr valve,then a whose,then another one,and another one,and not knowing about this intake being clogged
Hah, I had a feeling this is where I would end up doing. I'm chasing p0402 changed dpfe, still showing feedback insufficient flow. I'll do this, then check the hoses that come off the dpfe. It's right up front on the 4.2 liter. Thanks for the video.
Very helpful. Did you have to replace gaskets or can you reuse? If replace, how much were they? Also, Did you have any rough idling issues before. My 2002 F150 seems to have some small idling issues prior to the P0401 code. Thanks.
James Weimar thanks for checking out the video. I was able to reuse the original gaskets since they didn’t get messed up taking everything apart. I would imagine they wouldn’t be but a few bucks a piece. I did have some rough idling before hand.
I have the same model, but from '98. How difficult/frustrating is it to remove that part? And about how long to do so, clean, and re-attach it? My engine light cones on at random moments, but the PO401 is the only code I get. It must need a cleaning. I'm the second owner of my truck. The previous owner, a old man in his late 70s, took good care of it, but never replaced parts. I've already had to replace the waterpump. I can't imagine this being more difficult than that.
It wasn’t very difficult probably took an hour or two. However I will say that after I had solved that problem I ended up eventually getting another code P1406 DPFE downstream hose off. I checked the two hoses that ran to my egr and they were gummed up severely. That completely solved my issue. No problems at all after that. I have a video on that as well. I would check those two hoses. Most likely they are gummed up. Engine code P1406 fixed!!! Is the title.
What were the driveability problems you were experiencing before the video. My F-150 is a 5.4 1998 model, and idles fine, but misses as you go above idle. No codes yet; only an indication that the Evap system has a problem. Misplaced my good scanner that gives me the Mode 6 info. Thanks for making this video - very helpful.
I started getting that Code after SeaFoam shocking my 99 F150... the shock worked for Bank Lean code, and Manufacturer Control... I'm on my next fill up... So It maybe needed to burn off.
I have a 00 F150 that has an insuffient code that's popping up. I removed the throttle body cleaned it, changed the EGR valve and I'm still getting the code and the light on the dash. Any suggestions?
Check your DPFE hoses. Mine were completely clogged with emission gunk at first cleaning the throttle body worked. The I got another engine code P1406 (down stream hose off). I replaced the two hoses to the EGR and fixed the problem.
@@ErnestPreas YAAY!! I have changed the DPFE sensor reconnected my battery and its day three the check engine light has stayed off. 🤞🤞 Thx for your input!
Dean Nutz thanks for checking out the video. That particular code never came back however I ended up getting another code which was P1406 (downstream hose off) In which I had to replace the downstream hose. There were actually two hoses that are side by side that needed replaced. They were completely blocked by emissions crud that was preventing flow big time. I have a video on how to replace those as well if you would like to check that out also. I would check those hoses also because my downstream hose was completely blocked. That totally fixed that code and I haven’t had an issue with it since. Replacement hoses were probably 20-30 bucks at most if I remember correctly. Might have been less than $20
I had to end up changing my DPFE hoses that go to the egr valve. At first this worked however I ended up getting a different code which told me I either had a downstream hose disconnected or clogged. After checking I realized the hoses were completely clogged with emissions gunk. I did another video on that as well you could check out. It may be the problem your having as well.
Entirely unnecessary to remove. Come around passenger side of air intake housing. Pull off rear hose opposite of the two EGR holes, insert small screwdriver or coat hanger and open. Job done in 2 minutes. Next, change your spark plugs and stop buying cheap gas.

That hiss turned out to be a vacuum leak on my F150. Had to replace the head as they are famous for getting warped.

I've replaced the valve on my 07 explorer a couple of weeks ago. I've got the code today..
@@yousefd9014 it’s the hoses
@@omarflores6470 you don't know unless you put a vacuum gauge on it.
@@JohnSmith-xx1lx I just don
im going to try that on my 5.4 today. HOpfully it clears the code. Nice when you don't need to buy a part to fix it
Yep, it helped me and my 99 f150. Thank you.
Appreciate u boss🤣🤝 that service engine light was pissing me off

Your video helped me a lot thank you
Your welcome. Glad it helped. Thanks for checking out the video
Does the throttle body or anything that you had to take off require specific torque for reinstall
Informative video but spraying the brake cleaner on your driveway?? Really? I get pissed off when someone drops oil on my driveway.
There was a bucket right there he coulda held it over! Jeeeeeez

It would idle ok as well and would slightly stumble a little on take off and seemed to stumble while driving just a little.
@GR ABS light is likely a sensor, my 99, has been on for 85k miles, my po401code caused zero drivability issues , just a SES light
What the hell is that green hose connected to ur egr coz thats what i need to replace sense mines broke off
??? HOW LONG WAS IT BEFORE IT CAME BACK ON ??????
9.5 times out of 10...its your dpfe sensor.
I drive a 06 Ford and this is the issue and my cars feels like it's losing power
Right on great video buy the way did you have to get any new gaskets before putting back together
I think I was able to reuse the same gasket if memory serves me right
@@ErnestPreas right on thank you
I started getting that Code after SeaFoam shocking my 99 F150... the shock worked for Bank Lean code, and Manufacturer Control... I'm on my next fill up... So It maybe needed to burn off.
Gracias por El video de mucha ayuda.👍👌
Its not the throttle body...it's the Dpfe sensor.
What's that
Thank a lot I appreciate the information
Thanks brother your a beast 👍🏼😎
I have a 00 F150 that has an insuffient code that's popping up.
I removed the throttle body cleaned it, changed the EGR valve and I'm still getting the code and the light on the dash.

@@ErnestPreas I checked the hoses and they were free so I went ahead and order a DPFE sensor. I'll let u know if that fixes the issue.
Thx
@@kye389 sounds good let me know how it goes for you. Hopefully that will be the fix
@@ErnestPreas YAAY!!
I have changed the DPFE sensor reconnected my battery and its day three the check engine light has stayed off. 🤞🤞
Thx for your input!
@@kye389 that’s awesome man! I’m glad you were able to get it fixed 🤞here’s to hoping that engine light stays off

Ernest Preas thanks for that! I’ll check that vid and my hoses.
All that work , thinks I'll just pull hoses and spray into the passages / replace the sensor
Just did that and replaced a cracked exhaust on a 3.8. Suckers running better now but it passed smog with the crack.. .. it's cursed
Why in the world would you do that right there on your concrete not only that your daughter is breathing in harsh chemicals
OMG Karen for real ?
1. it pressure washes away not to mention its My #^*+#?! driveway!!!
2. she didn’t inhale any chemicals seriously???
Thank you very much it works you need to replace the gaskets to and everything was good
You don't need to replace the gaskets unless you rip them.
Sorry but could you have done that over an old towel or box etc? Hated to see your pavement get the stain
and it leached into the grass and soil
Ok Addy hold the camera still 😂
5:30: Thats crazy! My daughter says the same thing! She loves the smell of that cleaner! What is it with girls?
Mine likes pvc cement smell. Kooky gal
I’ve done everything replaced everything and cleaned still have code

Thanks Karen I’ll give that a try
