- 2015 Freightliner Cascadia GHG14, regen issues with the One Box. Fault codes present due to DOC face plug. SPN 3250 FMI 0, FMI 8 and FMI 15 DOC Outlet Temp High, DOC outlet temp signal spike and DOC outlet temp very high.
It is always important to check all fault codes in order to get a better visual and a better idea of what is happening so you can find a better approach.

Hi Pedro, hi to Charlie also, thank you guys for your video's they are so helpful. keep pumping them out again thank you for sharing your knowledge. Your also so fortunate to work side by side with your father, awesome.
Your teaching is outstanding sir I applaud your efforts 😊
Thank you.
These are usually one box codes but definitely check doc pressure tubes for cracks and blockage. Hardly ever doc sensors. Usually bad one box
I don’t have a Cascadia but what a great video.
Thanks for all your lessons
Fantastic on your dad! Thanks for posting!
Buen trabajo Pedro.
Great job 👍🏼
Extreme value 😮
👍🏿
If u don’t mind …plz include the price of parts and labor/hours for each jobs u do so we can have an idea when we go see a mechanic thank u!
Great video Pedro, sorry for my ignorance, but what do FMI’s really mean and tell?
The SPN generally is the fault code, FMI narrows it down to something more specific or an area more specific.
👍great explanation where is ur location
We are at
659 S Maple ave. Montebello, Ca 90640
Pedro please what manual can I start reading in regards to freightliner
I have same problem truck start smoking a lot and temp goes up to 1500 then trucks shuts off any idea what could it be
Your temp is above the threshold. It will shut down to protect itself from melting. What are the readings of the DOC inlet pressure and the DPF pressure?
Can ask you a question?
I'll ask anyway if you answer that would be great. 2014 freightliner cascadia DD15 GHG14 1.3 million miles
I keep getting a coad 3364 fai 2
It's not bad def.
I changed the def injector pump/ metering valve both the nox sensors. I've pretty sure I've got it down to the def is building up in the injector port cause everytime I removed the metering valve It's pulled off. I putting a awning kit in a couple of years ago cause of the different problem but it turned that the awning cause this coad when I removed it the coad stopped.
My question is why do you think the def is building up there? I don't have programming to watch levels. But I did start regan and disconnected the 7th injector for sec to see if diesel was coming through (nothing) I was thinking maybe my one box isn't getting hit enough to burn it off.i have no coads for the Doser block. But during the regan it completes in 30 mins but I use to could feel it kinda of jerk several times during the regan now it's just seems like high idle. Any ideas? Thank you
Also a year my fuel pump went out sent metal everywhere I changed everything except that doser block. Do you or have you seen a fuel pump mess up a doser block?
@@truckerbuddy3035 let me research this and I’ll get back to you Monday morning
so they opened up the one box cleaned it and re welded it?
Open up the side, clean the DOC from both sides and the. Weld it back up. Seal it like new.
@@CarlosDieselElectric what's the name of the shop that did that
Wow good to know
I have my Nox sensor out. Will this operation cause any damage to the onebox system or engine?
If the sensor is on the outside. It probably means the One Box is having NOx efficiency codes or issues.
Placing it in the outside just allows the Inlet sensor to compare air (gases) with the outlet sensor. Which means the NOx efficiency will be at 90% or higher.
The truck will run fine and won’t cause any further damage to the One Box. Usually a One Box will start to have problems with mileage, age and time. Of course, injectors can help contribute to a bad One Box.
What is going on with your truck?
How much the customer has been charged for all these works ?

@@CarlosDieselElectricI will call you on Monday
Haow muvh did all of this cost
Bake and clean the filters
Parts and labor. The cost is around $1500
If you need to clean the One Box or repair the One Box, the cost is more.
Do you have a overhaul video on a volvo d13 engine?
I do not. I don’t get too many D13 engines. Except for basic oil changes.
@@CarlosDieselElectric I have a 2015 volvo d13 blowing white smoke I change the injectors and cups but still smoking cylinder 6 on passenger side has oil leak am thinking the head gasket I took it to a shop and they said I need a inframe
Buenas tardes cuánto cobran por limpiar los filtros tienes un número para hablarte
Disculpa la respuesta tan tarde. Limpiar los filtros, las partes y labor. Aproximadamente $1,500
It appears that the one box was cut open and re welded. Shut. Is that how the doc were able to be cleaned
Correct, when the One Box is opened. It allows you to see the inside, repairs the internal housing and clean the DOC. The other option is to replace the complete One Box but we all know how expensive that is.
Thank you so much. I have often thought of doing it that way. But you know how these service guys are they say you can’t do they cause they just want to sell you that high dollar one box. I sure do appreciate your honesty sir. It’s so refreshing to meet such an honest man.
