Common Issues on Aftertreatment 

Whole system stupid and a complete unreliable piece of shit’ I’m sitting in 20 Anthem with 2500 miles check engine light on with SCR malfunction message 😡😤

Thank you for fixing my husband's truck. We really appreciate the help Adam.

Hi I have code keeps coming on. Spn 4364 Fmi 18. I have put new def doser on and drain the def tank and clean it out. Put new def fliter on and flush out all the def lines. I clean out the 7th injector. I do a force regen everything pass. But three days later the same code comes back on. The truck has 985634 on. The SCR and the DPF fliters are original. The DOC is 2 yrs old. I had all the fliters clean last yr..Maybe you can let me know where I should look next.

i cant get rid of soot level high, i changed wire harness, sensors cleaned filters and still reading soot level high please help 😊

Do you have any fixes for these codes: 520371, 520372, 4634 FMI 17 The primary code that pops up first is 520372 then the 4634 FMI 17 comes up after a while.

Good Morning everyone! I was a Car mechanic, and jumped to a Diesel Field, It is very different how things works, The Guy that introduces me to the Shop; had no Idea how to Start the Scanner Computer, nether how to Use J-Pro. Was Tough to starts, my English much.much bad, was tough to understand the words, the meanings of terminology .... but I Used Internet the way it was created for, knowledge(I think was for that kkk). After 2/3 years watching videos about Aftertreatment, Knorr/bendix brakes, Alison Transmission... I can do almost any thing, I still not comfortable when it is related to DOC,DPF, SCR, for the price of the parts, fear of bad Diagnostic and make costumer or shop pay thousand of Dollars for my mistake, I check And ask my col-worker to check and give me a second opinion on my Diagnostic, any if is it match, Goal, my Diagnostic was Right, and getting accurate. I learned a lot with your channel, there's others good too(I don't want to promove them in your channel). I wanna say thank you for your Channel, keep with that job witch is fantastic in my opinion. Best Regards Daniel Montuam.

Great very informative video.. Learned a lot and dispelled some of the "magic" in aftertreatment systems!

I like these videos you put out. After treatment diagnostics is something I struggle with. None of my coworkers have much experience with it. Do you have any other educational resources for this? It's something I want to learn and be able to apply at work.

Thank you. When people speak about the after treatment. I cant understand a word they say. It goes like this oh the truck cant breath and its got to many sensor, the one box is expensive and those filter going to cost you. Yep filter now are cheap than when i started, hell i seen them as low as 800 bucks. Now i understand how the system works. Now i know what to replace for prevention maintenance. I never knew about the 7th injector getting clogged. Or the lines line getting looked at. They made it seem like it was such a problem delete it. Not!

Boss what is the cause of coolant overflow on reservoir during start volvo d13 engine

2016 Volvo d13. 960,000 miles SPN 4364 constant since about 700,000 miles, been in shop SEVERAL times. 7 injector replaced, NOX replaced DEF filter in DEF tank replaced. DEF filter removed and baked all build up removed from DEF SYSTEM You name it it’s been replaced it or cleaned it. Check engine stays off for about 2 weeks (after parts replaces or cleaned)then right back on. Truck won’t regen on its own, manual regen once a week. Now we have SPN 5018. Truck runs great! Help, any suggestions would be greatly appreciated.

I have volvo vnl d13 500hp it is 2017. i have two codes sa 16 dtc p296800 and sa16 DTC p05EB00 which both are tied to the after treatment system. I think my 7th injector is clogged. What do you think ? no check engine light yet on the dash

I learn every time I watch your video sir. Thanks. Quick question. I changed nox sensor couple of weeks ago on my Volvo 2012 D13. The check engine light went off.I was happy. Then when I turned the truck off and then on , the check engine light came back with different codes. One permanent code is son 1231 fmi2. Where do I start to fix this problem. Thanks

Thanks for the awesome videos and if I’m ever in Texas I will be sure to make an appointment and just have you guys work on it. Although I enjoy watching the videos of it I feel is over my head mechanically. I have a 2014 Freightliner Cascadia that I purchased and I did a parked RE-GEN. It took about 45 minutes and it got really hot of course a check engine light came on towards the end and it said that it was a temp sensor for the DPF. The next day it was gone the check engine light went off. Does this seem normal?

Delete that bushit. 100 things less you have to worry about.

It's lots of information about emissions exhaust system but in India this year's all OEM introduce after treatment system as per the government guidelines BS6 norms

Can v talk I have Park region issue, after 600 or 700 miles it's say

Hello sir . I have 2017 cascadia with over million miles . Recently I m having problems with MIL light go on and off. With 3220 fmi 20 codes.Light comes on when I pull heavy load And go off when I pull light load .I change both inlet and outlet nox sensor and clean dpf filter and def dozer as well. Please advise me what could be the problem. Thanks

Hello Adam I enjoy your videos. I have a question for D13 engine oil temp. runs 234 -249 degrees all the time. Please tell me this is not normal. And should I change out cooling valve/ oil thermo?

I have a 2013 cummins that keeps throwing code spn 4364 fmi 18... I have replaced Inlet and outlet nox sensors, new def doser injector, new def filter, fresh def fluid and fixed and cheched all exhaust leaks and the code keeps coming back. I don't know what else to do

Been a diesel mechanic for 30 years. Great job describing this operation. I would recommend you guys for truck repair.

What could cause Temperance T3 goes 60 degrees ove normal, during Parked Regen? Should I change a sensor ?

thank you sir, I do road side service & now I am more educated.

Is like having 2 engines to worry about in a truck, but I understand why we needed global warming is getting out of hand.

Sir in india we found issue in every HAV vechile with aftertreatment system continues pop fault code of 5556 Nox conversion efficiency exist while in running condition. Please provide help to resolve it .

Avoid gas stations DEF. I’ve only had bad experiences

Adam . Im CDL-A drive im going to be a mechanic diesel soon thanks for help

A co the cho e theo lam an luong duoc ko

Dude thank you for making the after treatment system make sense!! Just got a issue with it today, freightliner dealer is diagnosed it right now thanks dude

I have cleaned my dpf and the build up in the def but my truck is still stock at 5mph, this has caused me so much pain

What is the amber engine light it turn on me while driving it’s not a check engine just the little engine yellow and it’s not blinking in the manual says it’s an amber engine light which is a malfunction of the emission system

That’s what I’m talking about Mr. Adam knowledge you the man.

I like being at work and I swear it'll be a wave of derates and bad sensors or bad filters and then outta nowhere it stops for 6-7 weeks

I got a question. I have a cascadia that cannot regen. I have to go in Wednesday to replace a sensor or something. But i do notice the truck vibrates/shutters/buzzes when applying gas at low speeds between 25-40 mph. Can a disabled regen cause this?

Hello Everyone, I have a question? When replacing injector cups isn't the valve adjustment included or a separate charge?

Have Maxx 13 prostate dog or scr or both a IDK can you help please?

Great video , well explained for those who are not familiar with the after treatment system

Nitrogen Oxides(oxides of nitrogen). Nitrous oxide is laughing gas...

Mfg’s need to have specific codes for each sensor going wrong. Is it possible for someone to completely maintain themselves?

Good explanation I have a problem I have a code 3225 it's something about the def do you recommend taking off def sistem or no thanks.

It's ok to change Cummins engine to Freightliner 2015

These sensors are almost impossible to get here in my country and we do not have active emission laws, someone should help me get rid of the emissions system

Where r h located Adam ?

I think it’s nitrogen oxide. Correct me if I’m wrong.

Where you guys located?

What can cause the ac system to blow the exhaust into the cab during a regen

Also losing antifreeze what maybe wrong?

How do you clean those filters out? What is the cost of servicing? Tkx

From one Adam to another...thanks for the video

I want some professional training to work on aftertreatment systems any suggestions?

Nitrogen oxides! Not nitrous

Really enjoyed the overview of the after treatment system. Can you tell me what a SPN 1328 FM 31 code is ? Look forward to visiting your new shop.

Location?

Interesting as usual! Thank's for trying to educate people regarding their tractor. Don't be shy to talk about trailer, reefer, etc... If the reefer are not your cup of tea, you can bring someone else to improve your RU-vid chanel! Good job!!!

Adam I need help with my after treatment ( defoe )

Cool videos. How do you test the temperature sensors?

Excellent video...good information.

What is a normal pressure on the differential pressure and what is considered high. I used to get a reading of 8-9. On Trk’s with 60,000 now in the last 4 months I’m getting readings of 27. I have 15 Cummings isx15 2014 too 2017. I Thank you 🙏 for time.

I have 2013 Volvo d13. What exhaust temperature should be at when I'm driving 65 mph

👍😉

Good shit,Adam. To u and ur staff

I like your videos, it’s very clear
