Check Engine Light. spn=3216/3217 codes. NOx Sensor.

[@SheDrivesBigRigs]

Thank you so much!! I just had this come up on my truck and you are the only one that posted something about code 3217.

[@RoadRunner_629]

You are very welcome.

[@wheelburnerexpress]

Good job dude. Unfortunately these days we’re not buying trucks. We are buying computers. They are just throwing the truck in for free. That’s good information to put out for all the guys with Cummins engines.

Thank you Wheelburner. Always a great pleasure to see you and Miss.Burnner around the channel. I just recently found out that she has a channel also, I subscribed to it and will be supporting her as well. I love what you guys are doing with donations for dementia patients. I also have lost someone due to it. It's a very sad situation. Much respect 🙏 🫡 👏 🙌 💯 to you guys!

[@KennerdWorthington]

Thank you for the info!

[@RoadRunner_629]

No problem

[@joshb3721]

Thanks man, had the code Monday. Just picked it up at Peterbilt, I have a 579. $957. Ridiculous.

[@RoadRunner_629]

No problem brother

[@josephadams7106]

I'm going to correct myself. That may be the sensor. I looked more carefully, and that's where my 7th injector is located, but I know my sensor is underneath the truck. As I followed the silver cover on yours, it indeed goes down, whereas my injector has a hose that goes around the back of the motor. Sorry about that previous comment...

[@RoadRunner_629]

It's all good man. At least you had enough respect and courtesy to correct yourself and not be an ass about things like most other people would be. Not saying everyone is like that but you would be surprised at how many disrespectful dumbass comments I get on things like this that I post. I post things like this to help people when they may be searching for answers on these types of subjects. Subscribe hit the like button and stay tuned!

[@American_patriot110]

Thanks man

[@RoadRunner_629]

No problem

[@genaivazquez6142]

Hey man, just got that 3217 code as well. Do you just have to replace it and it goes away,or do you have to hook up the computer after replaced? Thanks

[@RoadRunner_629]

Replace it and hook up the computer. That's not to say you'll have to do that as well, but I'm sure you more than likely will have to. Let me know what happens and good luck man.

[@genaivazquez6142]

Thanks. I appreciate it.

[@2mbili449]

At this rate much cheaper owning a helicopter

[@RoadRunner_629]

For real 😀

[@TolaTrucking]

I hope I never own a modern engine before I retire.

[@josephadams7106]

That's not the nox sensor. That's the 7th injector. It injects fuel into the exhaust stream when doing a regen. The nox sensor is under the truck at the dpf inlet, there's also one after the dpf to measure the dpf efficiency.

[@RoadRunner_629]

Kenworth said it was the inlet nox sensor. But I thought it was a seven injector as well. They also said the seven projector was right there on the turbo. Or behind the turbo I would have to look.

[@agir_vasita_yilmaz]

you not need anything else. you can connect "canbusemulator" and you can simulation all SCR and DPF system.🚚🚚🤩

[@RoadRunner_629]

10 4, thank you.
