Bless your heart for making this video thank you 🙏🏼 just what is wrong with my truck.. now I know to tell the mechanic to check for this.

Very good job bors

Hello sir thanks for video. I have freighter 2016 evolution and its has code Spn 3238 fmi 2, its has engine light from last 3 day's but check engine light cone n go, do i need to replace outlet knox sensor or just clear a code?

Could bad sensors cause my truck to use twice as much def fluid as normal?

It'is Amazing video,thank you for sharing this

This is exactly what i need.

They are all related so yes you can do the same t/s. Or jump to nox sensor verification test and check out the nox sensor hrs to see how high they are.

Thanks for the detail video, really appreciate it. Is there a way to test the NOX sensor with a multi-miter, would you do a video about, please. Also do codes get erased by them self as new parts get install or you most use a reset tool to get rid of the code? Thanks for what you do................saved my butt a few times already. reason im asking is because I got code 3057 fmi-2. and sensor was replaced 3 weeks ago.

Thanks for reaching out. You cant test the nox sensor but you can test the harness side for voltage and ground. Testing the nox sensors would be with a routine done through diagnostic link computer. And that would just read of there drifting. But once a new one is installed a regen and clearing of the code need to be done. In some cases an scr efficiency test will need to be ran to get it to clear. Hope that helps

Great question, there may not be an issue when comparing them. If it’s cold than they should be within 25 deg. If it’s just at operating temp they will be fairly close around 350 deg. When doing a regen inlet will be higher due to fuel dosing spikes. When outlet temp consistently stays higher I would suspect a faulty sensor.

This particular code is a closed loop code. If there is an issue with bad def, bad nox sensors , any temp sensor on the aftertreatment, or any blockages in that system. Any of those issue will cause this code to come active. The regen first is the best thing to do In order to see if there is a failure anywhere. If it passes with nothing obvious showing a failure than multiple scr effiencey tests will need to be done in order to clear this code or it will keep coming back like you have now. I imagine they only did a regen and not the eff test. That will need to be done and I’m sure it’ll help you out.

This is scr closed loop code which means your regens haven’t been running very well and your acm- after treatment computer is registering very poor values. This would have you check def quality and quantity than would do a nox sensor check regen followed by multiple scr efficiency tests. This code has plagued Detroit’s for many years now and can be expensive to fix. Usually 6-8 hrs in a dealer.

Hi. I have changed inlet nox sensor and did regen. Everything was good, after couple days I was going to delivery I couldn’t drive more then 10 mph.

Good question man. To answer the question easy. There’s so many tests that need to be done including testing the def, checking all the sensors,and monitoring pressures to ensure no plugging. I can’t give you a straight answer without seeing it in action. Majority of the time a sensor is drifting and or def build up in the scr catalyst.

does the code need to be cleared manually after the sensor is replaced? I replaced the sensor and ecc cleared 5 codes, but theres still 1 left after a week.

The code should be cleared with a computer to get ride of them. Some codes linger till it gets enough drive cycles to clear itself or till it runs through the right tests like regents or scr efficiency tests.

Thanks for reaching out. This can be a tricky one with low nox conversion. I would stick to basics. Check def doser quantity than check def quality. It’s possible you might have bad def. Than find out what your pump is doing while testing it. If all that passes than I’d start testing your one box and sensors with a low temp regen than actual regen to see if any sensor is drifting. If none are drifting your onebox may need to be replaced. This t/s will get extensive and you may need to get someone you trust on it to give you wise and knowledgeable info.

Sorry what I mean is, I had a diagnosis done by loves truck stop. And the report showed active and inactive codes. The active code showed I needed a new actuator. When getting a diagnosis everything that was diagnosed will either show active which is something you need to pay attention to, or inactive as it’s not a problem. When to velocity Freightliner to see I can have them put the actuator. After their dia they came up with the same report as loves did, but said I needed a nox sensor. Now on the report the nox sensor was inactive. After sitting there and four other trucker came through and needed a force regen, the company charged all of saying they needed nox sensor, but on all their dia-report it showed the nox sensor as inactive. Long story short, I took my truck to another mechanic which put the actuator on and he said I didn’t need a nox sensor because the code for the nox sensor was inactive. Haven’t had a problem with my truck since. In other words, I think velocity Freightliner is defrauding truck drivers just because they have check engine lights on their trucks saying that they all need nox sensors when the sensors are inactive.
