Infinity/Nissan Maxima EGR P0400, fixed by cleaning a tube
HTML-код
- Опубликовано: 13 сен 2024
- Check engine light on a Nissan Maxima showed EGR P0400 problem. I removed and cleaned the EGR valve. I also found a tube running from the EGR area to the intake manifold. It was this tube that was plugged solid. I drilled out the carbon built up and cleaned out the tube. Put it all back together and the check engine light did not come back on !!!!

Finally got that pipe out it was completely filled with crud thank you so much for your help couldn't of done it without you. big help thx
Thanks so much and glad I could help out. Not sure why these Nissans plug up so bad. A lot of people don't even think of checking that tube !!!! Glad you got it all done. Have a great weekend :)
@@GarageKing thank you
I used Marval Mystery oil soaked it for 3 days and used Qtips to scrud the valve leak area and finished it off with brake cleaner. Mine was slightly stuck open. 2000 toyota camry with original spark plugs i paid 200 bucks for the car. I love it. Next Spark plugs.
200 is a deal for the car, and I have heard Marvel Mystery can do some great things, thanks for the comment !!
Okay I had the P1400 code and really find it hard to remove the housing of the heat sensor. So what I did was just to remove the heat sensor itself without the needed fabricated socket wrench, sure heat sensor must not be tightened too hard, just an open wrench will do. Cleaned the dirty heat sensor, used wire and air pressure to clean the base as much it can reach. Now my Infiniti 130 is clear and pass smog test this week. Thanks for your vlog. Just great.
That is awesome and glad you were able to fabricate a tool to get the job done :) Good on you for that!! Thanks for the great comment and have a good day :)
Great video, I've been getting a funny idle lately so I wanted to kind of process of elimination the car and pop the air box, throttle body and MAF off and the idle air control valve. And the EGR valve and tube and just inspect and clean it all at the same time and put it back together, but I couldn't find a good video for the valve and tube. Thanks man great video.
Thank you for the great comment, sometimes people post that I'm too technical, sometimes not enough. I'm really happy I was able to help you !!!! Thank you and happy Saturday to you :)
Nice Video. My vehicle was stumbling and dying. I had a P0174 code leaning out Bank 2 as well as a P0400. After a ton of work and watching videos, I determined the MAF sensor was misreporting air flow, so I replaced the MAF. Also, I cleaned my tube out. Was plugged just like yours. I did not remove the EGR. That tube was really fun to get out. UGH!!! Clean Sensor and tested Solenoid. Applied 12v and could hear it clicking. Checked for Vacuum at the hose on top of EGR and got vacuum as I revved up. Felt the diaphragm as I revved up and could feel the EGR diaphragm move. Cleared codes and vehicle ran fine. No more stumbling and I thought I was home free. However as soon as all the system monitors were ready it through a P0400 again. That tube connects to the EWGR valve "Spacer Block" I wonder if something in there is Blocked. What are your thoughts? Deeply appreciated.
Hey there and thanks for the detailed comment !!!! I know all about taking that tube out, lots of fun haha!!! The spacer block is definitely a possibility. I know when I took the EGR out it was kind of clogged up on the right side (when you are looking at it from the side of the engine) that's the part that has those bigger threads on it, there was quite a bit of crud in there. I poured a bunch of carbon cleaner in there and cycled the egr up and down with my fingers. This code could be the result of any carbon blockage anywhere in the EGR path so its important to clean it all out everywhere. Taking out that EGR was a pain in the butt as you have to be careful with that big threaded part. Also if you have a sticky EGR valve it can cause that code. I'm not sure if taking the EGR out and giving it a really good cleaning helped, but I basically just cleaned everything out and then afterwards it was good. Its too bad these engines are not a little easier to work on........
@@GarageKing Thank you so much for responding so quickly. I just went ahead and removed the EGR. Some gunk in it but I wouldn't say it was clogged up like that tube was. Gases should have been able to pass. I cleaned it up real good and try to spray back into that spacer block the EGR valve bolts to.. After all, as you know, that is where that bottom of that riser tube is bolted up, (the spacer block). I want to now test the EGR valve with a hand pump vacuum tester to see if it holds vacuum. I almost feel like the EGR pentel could have been stuck, until I freed it by pushing up the Diaphragm with my fingers. In any event, I cleaned it all up. Only thing I haven't tested is the ohms of resistance on the EGR Tube Temp sensor, but I cleaned it good too. so after I get it all back together, I will let you know the results. Thanks again.
@@jefftravis5312 Good call with the EGR pintle, it could be sticky, when I cleaned mine I soaked part of the internal slide (you can see it when you look through that rear hole) I would test it with a vacuum pump like I did as you never know. Also check that short piece of rubber hose that is connected to the steel line that runs to the EGR to make sure there is no small tear in it. I know these things are a pain, but it sure feels good when you get it fixed !!!!
@@jefftravis5312 I just finally deleted my EGR valve and tied my sensors up with zip ties and called it a day I got tired of it lol. Blocked off the intake hole and the hole from the exhaust to. Worthless junk that causes headaches.
I was laughing so hard when bandit started calling. I didn't know he had his 🐶🐾 own cell phone now 😂! That music for a minute had me feeling Pulp Fiction vibes.
That Bandit, he is the star of the show at times !!!!! I try to fit him in whenever I can !! Thanks so much for the comment and I hope you are having a great day :)
5 Like excellent video good and very helpful information about car that what I always like about your channel I always come and learn something . Have a great weekend with family. Love the crazy dog too much😁😁😁 EGR is nasty
Ya that crazy dog is Bandit, he shows up in videos from time to time :) This one was a good fix that really didn't need any parts, just a cleaning.
I had a maxima before..I loved how it drove.
They are nice cars, this one belongs to a good friend of mine, still on the road !!!!
Always interesting 😀
Thanks! 😃 I do appreciate it !!!
Oh wow! Another super interesting video! Always enjoy watching 👍🏾❤️❤️
Thanks so much, great to see you my dear!!!!
96 Like I am at video number #20 love this every detail how to make thing work save big moneys when we do this ourself ! Your channel give peoples confident to try at home. Playlist checking still running
Thanks so much, you are going to be mechanic after this !!! Right now just checked and I'm on #66 of your daily life video :)
@@GarageKing thanks for everything I will run your next playlist tommorow when I online
@@shahnawazvlog6266 Thank you !!!!
Always an interesting and helpful video, the new intro love it
Glad you like it, I try to make every vid a little different !!!! Thanks again :)
Very helpful
Thank you for the comment !! I do appreciate it :)
Great video! Man the amount of work going into these videos, impressive sir!
This one was a lot of work!!!! I doubt I can make them all like this LOL :) But I will try haha!!
Wow I learn so much from your videos. I love how well lit your videos are so it's easy to see what's going on. However my check engine light went on a couple days ago and I still relied on the family to fix it instead of doing it myself 😅 Full watch and shared your channel with my dad and brother though because I think you do a fantastic job.
Thanks so much for the great compliment. I do really appreciate it :) Sorry to hear about your check engine light coming on, but I’m glad you got it fixed up, I appreciate you sharing me out :). Thanks !!!!
Always useful sharing GK. Thank you so much
Thanks so much you two, and hope you are having a great weekend :)
Just catching up with your video sorry for the late visit like i said before you make it look so easy
No worries at all, glad to see you brother !!!
Very well explained loads of clamps. Easy to handle tools.too x
This one was a little more intense !!!! Thanks so much for the comment :)
@@GarageKing I'm still watching was going to ask how did you film is the camera on a shelf?
For this video I used multiple tripods. I have a taller one for a full engine shot, and smaller ones that I place around the engine for close ups. I also have a clamp one that I attach to the underside of the hood/bonnet so for these bigger repairs it’s a lot of different shots and angles. I probably had about 60 short clips that I imported into FCP and then made this video. These ones take a lot so I only do big ones like these every now and then as they are pretty time consuming. These ones are great ones for people learning to fix their cars. Not many know just how much editing goes into these ones. Thanks for the comment :)
Great stuff G!
Appreciate it! and thank you as always :)
The dog GIF🤣
You Liked that one!!!!! Ha Ha!!!
Nice video. Mr. Fix it. lol. Have a great day.
LOL, ;) Love it, Mr. Fix it ;) Thanks :)
New intro👌🏽
Always trying something new, gotta keep it fresh !!!
Looks like the throttle body coulda used a cleaning service.
You bet !!! Did you see how filthy that thing was !! I think the whole upper intake could have been taken off and cleaned. That tube from the upper intake to the EGR was plugged solid at the top. I never thought I would have to drill out carbon !!! Maybe a catch can would help this thing??? Not sure. It was my friends car, an interesting fix for sure !! Thanks for the comment and have a great weekend brother :)
Wonderful share dear stay connected
For sure and thank you :)
Thanks
Thank you for the comment. Appreciate it :)
Thanks for sharing
Thanks for watching! I do appreciate it along with your comment !!!!
If u remember what’s the part number for the Egr Valve gasket and Egr guided tube gasket for the top one ???
Oh geeze, I have no idea, this was one of my earlier vids. On my new vids I post the part #'s, but as I say, it was one of my older ones. If I remember back I think I supplied the Vin# and went to Nissan as their parts department has the blow up pics and you can tell them which gasket you need. I was surprised at how plugged it was.
Hi. I've got an unmodified 1998 Nissan Pathfinder, 164,000 miles, 3.3L V6, 5 speed automatic transmission. Owned by an elderly couple...treated well.
10w-30 oil/filter is new and full. Same with transmission fluid.
When it's first started it knocks or loudly rattles for 3 seconds. Then it stops. Once warm it will only do the startup rattle about 50% of the time. Exact same noise returns from about 1,800 to 3,200 RPM and then stops. Also, the noise quiets and sometimes disappears between 1,800 - 3,200 RPM if I let off of the accelerator and coast. It also will not do it sometimes if I'm going up a steep hill slowly with the RPMs are in that midrange, under the hill's load.
The noise increases in speed and loudness with increasing RPMs. It sounds like 1 or maybe 2 cylinders of the 6, to me.
The main bearings and rod bearings were changed. Looked good, some rod bearing wear on a couple but not serious. No rod or crank shaft slop was noted before or after replacement. Made no difference in the noise. The crank was NOT sanded/polished.
It throws a P1400 code for EGRC Solenoid Valve error. I don't notice any idling or power issues though. It returns within a few minutes after clearing the code. Could this cause a knocking noise at certain times like I have?
I've narrowed it down to 5 things based on its part time occurrence:
1. Flex plate?
2. Timing belt tensioner failing (unknown when last changed)?
3. Torque converter?
4. Hydraulic lifters?
5. EGRC Solenoid Valve?
I have two short videos I recorded it and can share if you want to hear it. Thanks!
Hey There, and thanks for the comment. Yes please send me the videos, you can email them to garagekingcanada@gmail.com I won't be able to get back to you tonight, but I will get back to you tomorrow :) I'll take a listen, and let you know what I think :)
@@GarageKing thanks, will do now!
What is the name of that tube with all that carbon buildup
Hey thanks for the comment. Its probably the EGR bypass tube, but I think it probably has a few different names. I think best thing to do would be to call Nissan, give your serial number and they can pull up a diagram of the EGR system, and you can just pick out the part. They may even just call it a tube. Glad you found the video :)
Just wanted to ask and know I bought one of these for 1800 at 132k
Was that a okay price and are they good reliable daily drivers
It's currently in the shop it would shut down while driving or at a stop
It was not a gas pump or fual lines
They told.me the mass airflow made it do this
Hey There, and sorry for the late reply, in your comment you wrote "told.me" and RUclips flagged it as an external website that could be dangerous, so your comment was not published. If there was no period it would be ok, but the period made youtube think its a website. OK, enough of that. Yes the mass airflow sensor can make your car shut down.
I just got my 96 at 112,000 for 2,500
If the egr valve is clogged like this, does it vibrate and rev fluctuate when the vehicle is first started, when the gear is in neutral or when it is in drive mode, while waiting at the lights?
Hey thanks for the comment, I do remember it ran a little rough, and seemed like it was down on power when you first started accelerating. As you saw in the video there was absolutely no flow at all.
My 99 maxima keeps diying at red lights and sometimes even when driving. It has the same code so it must be super clogged and it can’t breath and just kills the car
Its a common problem, its just a pain to get to the part. Plan a few hours. Good thing is its not expensive, just time consuming.
How did u install the upper gasket for Egr tube ???
Not sure what you mean. I know there is a tricky part with that pipe, but I just took my time at it. Its really tight in there and you have to take your time.
I have a 4th Gen Maxima with Electronic EGR. There are currently no Trouble Codes but the engine would hesitate around 2,300 rpm unless you step more on the accelerator then only it would rev up. Could it be caused by a clogged EGR?
That clogged EGR can cause a number of problems. Normally on the Nissan the EGR itself is not clogged, but its the tube that goes to the intake that gets clogged. I know they can cause weird things to happen, even hard starting, so I would say its possible it could be causing your engine trouble.
i finally found that by adjusting the TPS sensor alignment to about +8% and then remove the key and then start it again ( allow engine to relearn new TPS idle position ), the hesitation issue was finally resolved.
@@vkpc1 Hey There, I would have never thought of that !!! Very glad it worked and I'm going to take note of this for next time. Thanks for the follow up and Merry Christmas to you :)
How long would you say this took to do?
Hey Thanks for the comment. I would say it took about 4 hours, and only because I struggled a bit with the threads on the big EGR pipe, and you have to remember I was filming it !! Most of the time you just have to take off the top pipe which really should not take you that long, maybe an hour or two if you take your time.
Great video except for the PIP screen baloney and the lame music blasts - an unnecessary detraction.
Appreciate the comment and feedback, one of my earlier vids, the music comes from the RUclips library and the PIP, well I was experimenting LOL. Have a good weekend :)
2nd!
Thank you Nish !!!!!!
what year Maxima is this car?
Hey there, it’s a 1996 so a 4th gen. 1995-1999 should all be the same. Newer/older years should be similar as Nissan did not change the engine design very much. Thanks for the comment :)
@@GarageKing The 99 Nissan Maxima had a electronic egr totally different then the earlier years of the 4th generation
@@nipples727 That is good to know. You taught me something as I did not know that. I thought that all 4th gens were the same. Thanks for letting me know :)
@@GarageKing no problem good video
