Hey I have a 2016 Peterbilt 579 with paccar and have 2 faults almost the same. Spn 3227 fmi 10 and spn 3227 fmi 21. Both description. Is After treatment outlet 1 perce t oxygen 1. Any ideas what that could be?

Please tell how did you figure out that the outer NOx sensor was bad? Both sensor's parameters were pretty close. Thanks.

Законопослушный Гражданин Compay had a bad batch of DEF fluid after testing it. When Truck was Regen cycle levels did look ok until started dosing DEF Outlet Levels were off. NOx Sensors very sensitive fail very easy with bad DEF.

Thank you

I have Negative 200 ppm on my outlet nox sensor . It shuts off during an SCR test. I’m thinking of replacing the same thing.

Jd Jensen Outlet NOx sensors go out all the time I lost count how many I’ve changed.

Thanks for the video. Does anyone know of a good scan tool that's not too expensive and can graph NOX input and output to get an idea if the NOX sensors are bad? Ordered a Ancel HD3300 Pro, but hasn't arrived yet. Driving a Volvo 780 d13. Currently have a CanDo HD Mobile, it resets some codes and does dpf regens.

I'm sorry to tell you but you won't be able to see those values without using Tech Tool. Volvo is very protective about there programming at work when I'm using Tech Tool must be online logged into servers document Active Codes Updates available for programs. You should be able get codes and do regents from Dash display see soot level.

Awesome video. I’m working with a Cummins 6.7 that only as DTC P0131. Any thoughts, should I replace the bank 1 nox sensor?

I would clear code if you can and run a Regen if it comes back Active change it out.

Dime Hermano, what’s going on brother, New subscriber here, 👋 I love that Snap on diagnostic tool, 👌 just had a curiosity I was wondering the last time that the sensor was changed and or how many miles on the truck got a curiosity just to make a comparison because I got a customer of mine that is having a similar problem and I want to make a comparison, thank you, 👋✌️

It's been awhile since worked on that truck know it mileage. When checking with scanner you can look at inlet Nox levels and compare to outlet Nox levels. Usually data will be erratic numbers will be out of spec. Each manufacturer has different values have get info on Truck. Plus depending on year there's levels on emissions. Like 2007 and 2010 would be different 2010 and up more strict on Nox levels output.

I do have a problem all day long says EEC spn 3936 And my truck never does region by itself or ask for region and the engine light is on can you please help me with that for Freightliner Cascadia 2016 Thank you.

You can try getting some numbers from DPF filter from another truck. Then with Detroit Diesel program you can type Serial numbers from other DPF in like you replaced it. Do a forced Regen when it’s done type back old DPF numbers . Gets you by but you will need get DPF system serviced.

Check engine light on you can go a little ways but when goes into Regan again it won't work then Truck will go into Derate about 25mph. Then Shut down light come on you better get off road.
