Great video, glad you found the problem, I’m having a similar issue with a 2017 Chevy express van 2.8l and it’s throwing code p2baa Nox exceedence low reagent consumption. nox sensors have been replaced, A lot of people are saying it could be a clogged DEF. Any help 🙏
yea you need to check your injector if it's working good and also the Def pressure, the pumps on these trucks fail often too
Thank you for all that information it’s really good video, I just had the same problem happened yesterday or the day before and working I did or what do I have to get to fix it? I don’t have nothing to only thing I have is the iPad.
yea u need a scanner to do this process sorry
good video. You say where the no 2 sensor is located....at the exhaust pipe. Where is the no 1 sensor located? Thanks
the NOx sensor #1 is always at the back of the turbo exhaust portion it usually has like 8 wires and #1 is always closer to the engine, the #2 NOx sensor is always in the middle of the DPF filter but on some models can also vary on their location.
What model Autel reader do you have? I have the same issue with my 2018 Chevy 2500 and need to do the same reset. Speed limited to 65 MPH for 75 miles. The Code was P2ADA.
What if it doesn't give no no option to star the test like the "start butoon" bc i already went throu active test > Reductant system > Reductant fluid quality test but i dont see no "star button" idk if it is bc i have a different scanner like the obd2 car code reader and auto diagnostics..
Hello, so my 2015 duramax had the poor def warning, so I just had both NOx sensors replaced about 2000 miles ago, did a regen after that, everything was good until yesterday the poor def quality warning popped back up. I put in a jug of Blue def about 300 miles ago, so I doubt the fluid is bad or it would have sent the warning much sooner. I dont have a fancy tablet scan tool, what can I do to fix this so I can get to work?
i am sorry to tell you this but you need someone with a scan tool that is the only way to fix this issue.
even some shops having the fancy tool need experience with this problem because it could be a temperature sensor or just a little detail and the only way to figure out is to go through all the steps specified by the dealer. that is why is a frustration to reset this light and is even worse when it gets to 5mph.
What model scan tool are you using to do a forced regen autel model
i use 2 models autel im608 and autel elite.
Had truck in shop for poor quality exhaust fluid. They replaced 2 nox sensor and everything went to normal for about 3 months. Now I have the same problem again. What can I do now?
most people do delete on these trucks but unfortunately if u life in state that requires emissions test you need to fix it and it is crucial if you have a high end scanner, on all the years I have worked on these trucks most common things are Def heater, Def pump, egr valve, egr bypass cooler and DPF injector and also Def filter.
I am having trouble passing this test on my 2014 chevy. When I run the test it says it says "Reductant system adaption diagnostic" failed, right at the beginning of the test, The quality test continues but fails. I can't find information about what is involved in the adaption test. I am at 40 miles until 4mph, no codes. I have replaced both NOx sensors and the MAF sensor along with the def injector, pump is at 500, runs around 15%, tank is full. Any ideas?
Hello having issues with my 2011 gmc Sierra Denali 6.6 duramax .. was driving and completely shut off… Level LowLow exhaust fluid poor quality and low fuild level shows on dash ,,,,,plugged in scanner and shows P0463 fuel level sensor
P2202 NOx sensor low
P0463 NOx sensor high
P128E fuel rail pressure performance
Please help this is my work truck need it on the road. Th
most likely is gonna be your lift pump or fuel filter clogged.
@@JVFIXLLC thanks bro
What brand model scanner, PLEASE
i use autel brand for everything but is too expensive for people so if yo want something really economic and does the same functions like autel check the review i did on this scanner.

2016 Silverado 3500hd dura max exhaust light blinking and it limit the miles to 55 what can it be wrong ?does it need def ? Is it low on def?
it could be low def but if u filled it up it could be an issue with a sensor or even the heater for the Def is hard to diagnose without a scanner.
By the way that was a good video. My truck is 2011 6.6 Duramax
I have a 2019 chevy equinox LT Diesel keep getting warnings saying poor quality.But no codes are popping up. I changed all sensors it still comes on so i am going to try draining all fluid and start fresh do you think that may work?
if u di all that a scanner is needed to reset the counter that u changed the sensors, but I believe your issue could be something else.
Thanks I got the same problem 🏋️♀️🤺👍🤗☦️
hope it helps u out these trucks are a nightmare sometimes
20011 Chevrolet 6.6 exhaust fluid light keeps flashing tank is full of fluid try to reset by key,on off still on what next
sadly u will need a good scanner to reset that light. the Def system on these trucks is complicated sometimes.
I subscribed because your video made so much sense to me. I have the 3500hd diesel
thanks man. trying to help as much people as I can.
@@JVFIXLLC I’m a lady. It’s ok 🤪
Hello there, i have a chevy cruze diesel 2014 and since i have the car i always had problems with the def exhaust fluid system. Poor quality blablabla, they changed sensors, fluid, even the tank once, the problem is always coming back no matter what. I am about the search for a garage that can chip my car so i don't see any fluid related problems anymore. What do you think?
honestly chevrolet did such a horrible design with these trucks and cars running on diesel. I haven't flashed a cruze before to cancel the Def but I have done it on trucks I think it could be possible but u have to think also if u are in California you will need all stock but if u on other state I would say go for it.
Hello , Great videos>> I Have a 13 LML 2500 with 37k miles , The engine light came on during a regen and I checked with a small scan tool and found code PO420 .Could it likely be the 9th injector with this miles? Hasn`t gone into lip yet... Thanks
that truck could have a software update i did a smilar one 2 years ago and was giving false codes about the cat and by replashing the ecu it fixed the issue.
I have a 2013 Chevy Silverado 2500 diesel 6.6 Duramax p205b ?
that code is related to the Def heater, if your truck is newer it might have a recall for that a did a 2015 and had a recall on that.
A comment, I replaced both of my Nox sensors but I did not do a regen, my DEF light is still on, I am going to do the regen in the morning my codes are P-2202, P2200, P2203 and P2009
I have 2011 Chevy and my nox 1 (24-30ppm) nox 2 (2-8ppm) sometimes nox 2 goes up higher than nox 1
Reductant pressure 73 psi. R injector cycles.!
what codes are u getting?
I have replaced all nox sensors. The system is working but will not release the service exhaust code.
u have to use a scanner to reset the Def system it won't do it if u drive it sadly
Yes of course. But, we have tried 5 different scanners and combinations of scanners. Although the regeneration is working and truck has no codes, it remains in limp mode. My mechanic has ran 10 ro 20 testes amd scans. But, truck remains in limp mode.
I have a 2017 Chevy with an Edge CTS3 it is showing codes P249D and P20EE. Does this mean that I need to replace the Reductant Control Module?
sounds like u have a bad reductant pump that's the one in charge to pressurize the Def line to inject it to the DPF. if the pressure is Below 12psi the code will set. it needs a diagnosis to find the issue but what mostly fails on these tucks is the Def heater and the pump. injector is very rare to fail but that can happen too and set the same code.
When it does regens I notice that the fluid temp is always very close to outside temp. and doesn’t warm up. Thank you for taking the time to answer my question.
no problem.
I am having the same problem on my 2012 chevy silverado3500 dually and I have done multiple scans and it doesn't go away. What do you think it might be?
go to control module and select special functions and there you will see reductant data reset option. also a good trick is to go to the live data pids under aftertreatment data and it can give you a closer look on what the ecu is seeing and why is triggering the light these trucks have a common fail with the reductant heater and also clogged EGR cooler, there is many reasons why the light will come on and honestly these trucks are a nightmare when you do not have experience dealing with these problems. but i can help you out a bit.
what codes did you get when you first scanned it?
No code. My mechanic searched for scanner to find out nox 1 wasn't working so he changed nox 1.
My 3500 is doing the same thing so I guess I need to change both sensors. I have already changed NOX1 so now I
M going to change the NOX2. I had the same code. When I change the other sensor I hope that this fixes my issue.
what codes are u getting. it's very rare for the nox sensors to fail
@@JVFIXLLC codes P0101, P11AF, P140C, P11CB. It’s a 2013 3500HD. Psss I’m a lady
I deleted my 3500 GMC DENALI 6.6 DURAMAX. Runs great used the Big Dog system.
yea the delete is hella better but sadly we are in California and we have to follow the rules 😥
Where can I contact you. I am here in CA I would like to bring my truck to you
If I have a code u0106 loss of communication with the glow plug module, could it affect the operation since I have limited to 4 mhp on the board, did they shut down the system with tuning or do I have to do some special function?
if you have lost communication with the glow plugs module it will automatically trigger the check engine but it is separate from the Def system. so you will have to adress that issue first because if u use a scanner to reset the Def system I am not sure but I think it will fail because there are strong fault codes stored.
@@JVFIXLLC The def system has already been eliminated with software. Is it still necessary to do the learning with the scanner?
7:59 why does the idle kick up when I put it in gear. Stop sign high idle 8 to 850 rpm. Then if I park have to wait for it to kick down to normal idle. 😂😂
What is the model number of your scanner, thanks
I use 2 scanners from autel the one in this video is Autel Elite and the one I use the most is the Autel IM609pro really good scanners so much better than snap on and more affordable.
Hi I have to code and the same light is on
these trucks are a nightmare sometimes to find the issue, fastest way to diagnose is with a scanner and know how to use it too
I need your advice my truck has the poor quality exhaust fluid on ...no check engine light on or no codes ...how can I get rid of poor quality?
do you have the speed limited in the dashboard? first do a cold start in the morning and let it warm up that will test the reluctant heater first and if you get a code about that I will start first there I have changed so many reluctant heaters on many of these trucks the emissions system was designed so bad and any minor break will automatically limit your speed with a scanner is faster to diagnose it.
Are you located in Houston by any chance?
Don't get any codes at all.
I ordered both nox sensors. They look identical. How do I know which is the upstream and which is the downstream
yea they look identical but the difference is the connector, one only fits up and the other down, once u get them check first by connecting them and you will see they don't fit in the same place.
I got a update so my truck stayed in limp mode but I tow a 10,000 pound concrete pump on the back I was on my way to the Diesel doctor to have them force a regeneration and on the way there I was able to clear the codes just by driving it someone had told me that my truck wouldn’t regenerate while I was towing because I’m in such a low gear and so far so good. I went to talk to the mechanic and told him I’m just gonna run it I have no lights on no more DEF flashing sign no more limp mode. I hit 80 on the freeway on the way back. Praise God.
This was after changing my NOx sensors and being in limp mode it reduced me to 55 mph. It was not the countdown or it gives you 65 mph for so many miles and then keeps going down as you drive. This one just took me to 55 mph and I was able to travel over 100 miles like that not sure what my limit was so I was nervous
Name of scan tool?
i use the autel im608 and is a bit expensive but i have a review on a new scanner i just got and it does the same functions and is more affordable
What is the new one@@JVFIXLLC
@@JVFIXLLChow bout the obd2 scanner ?
Does it work in this type of situation and if "yes" how does it work to dismiss the message on my dashboard "exhaust fluid quality poor" ??
on a diesel Chevy truck is called knock sensors
more likely headache truck lol
All that? Delete it....
yea is better lol,
