Before attempting the clean or replacement always check the wires on the 02 Sensors. I saw wires get hit by a stone chipping the insulation and messing up the signal the sensor was perfectly fine. Always inspect the wires first before jumping to buy a messing with fixing.
One of the few videos getting to the real problem. I don't care about the outside protector cap of the sensor. I need the zirconium stone inside clean, and you are getting to that both by soaking and spraying into the venting holes. I think you made headway with capturing your trash in the bag. Now I will try this with testing before and after. With the trash I think you are on to it, good video, thanks.
Do not do this. NOx sensors are not spark plugs. They have very delicate chemical sensing electrodes inside a fragile ceramic element. Soaking the sensor in any "cleaner" will cause the sensor to read very badly for the first few hours (if not kill it). You will be at high risk of setting a fault. If there is some soot on the outside of the probe, you can wipe it off with a dry rag. Under no circumstance should you allow a fluid inside the probe tip.
@@DrDrobotnik I cannot provide any "official" recommendations. However, IF: 1) it were my truck and it was outside of warranty 2) the sensor had relatively low hours and might have set a fault because of soot... Then I might consider trying to clean it just on the off-chance that it helps. In that case I would wipe it and use pure Acetone or 90+% rubbing Alcohol to soak, shake it out, and let it dry for about half an hour in front of a fan to help draw the vapors out. Do not use any fluid with additives, as those additives could permanently poison the sensor. This is why I suggested the pure volatile solvents. Be careful removing the sensor probe from the pipe, as they are often stuck and easy to damage upon removal. Be careful you don't get yourself in an engine de-rate situation if it doesn't work. Most of the time, this kind of cleaning repair on NOx sensors will not actually address the original problem even though the fault code may not come back--but you'll at least feel like you accomplished something. :)
Do not do this if you are under warranty. If you are outside of warranty, do not do this unless you plan to throw the sensor away anyway. You are at high risk of either ruining the signal long enough to set a fault, or breaking the sensor outright. If the tip looks a little sooty, just wipe it off with a dry or slightly damp rag. Do not allow any fluids inside or spray it with anything unless you don't really care anymore, as it contains delicate chemically sensitive electrodes. This is not a spark plug -- as indicated by its cost. If you insist on running this little experiment, then using pure fluids that evaporate without residue. Acetone, 90+% rubbing alcohol, and Carb Spray. I suggest you avoid using anything like fuel injector cleaner or WD40, as they evaporate slowly and contain additives that could permanently poison the sensor. FYI, I work on NOx sensor design.
Gasoline sounds like it should be ok to clean a sensor since there is unburnt gas regularly flowing through the exhaust albeit in low concentration. What would you suggest to clean it?

Something like 100% Acetone. I don't know what good it'll do you, but at least you're less likely to kill the sensor.

It's not a Knock Sensor. It's not at Oxygen sensor either. He's saying NOx as in oxides of nitrogen. NOx sensors like the one he's cleaning can cost $800 each. NOx is NO1 and NO2. It's an acid rain particle with one nitrogen and either 1 or 2 oxygen atoms stuck to it. The "x' is a variable. NOx is formed at temperatures over 2400°F. A NOx sensor is part of a selective catalyst reduction system. In simple terms- diesel exhaust fluid (DEF) system that uses urea to neutralize N0x into ammonia. The system will have one in the front by the turbo and one at the end of the exhaust selective catalyst reduction unit.

It throws a check engine code that you see on the dash. The code is read with a code reader. I think the specific code number may be unique to each brand or model of vehicle.

Sensor alone is $600 each, have to be replaced in matching pairs.. I have issues with my SCR throwing a P1C54 Code. Tech at Nissan said it could be a $4,000 SCR, (no diesel techs at any Local Nissan dealers) Nissan corp is no help at all, I have 23,000 miles on truck and they abandoned me. After 3 years.. plan on, if truck last to delete it after warranty, that is not really helping anyway,.. I am just in a survival mode right now as I don't want to keep replacing cheap built Nox Sensors.. every 23,000 miles. And I do not have equipment to put the truck into an Manual Regen mode and reprogram the system, and I don't want to go into limp mode..
@@Funky4me21 That sucks. P1C54 means "Catalyst Missing". Essentially your outlet NOx sensor is seeing a lot of NOx (or DEF), so it thinks your have removed the catalyst. This indicates a severe issue with your DEF dosing or conversion across the catalyst. With such a young vehicle, the most likely culprit is your DEF doser. If they've replaced the sensors, and that did not fix it, then it's unlikely the sensors are the problem. Maybe ask them if they checked the DEF doser, and also check for urea deposits near the DEF injector. If you're in a cold climate, it's also possible your Urea is freezing up.
if you insist on trying, use something that doesn't have additives (leave residue) and evaporates quickly...such as carb cleaner. don't use that injector cleaner. still probably a waste of time
that might just work. Drill some more holes so you can clean the sensor. Wrap it up with some metal sheet. These fcking sensors are too expensive to be replaced.
I know this is a bit late, but try replacing your spark plugs. They're cheap and hopefully it'll clear it. I had a '97 cavalier that burnt a plug and replacing it cleared my p420 code. Can't hurt to try.
A knock sensor is a totally different thing. But that is correct. You cannot drive your car with the o2 sensor disconnected. Options: Walk, bicycle, ask a friend to drive you or just don't go anywhere. These are all better options than complaining on a TH-cam video comment section.

O2 sensor is for gas cars and nox sensors are for most diesel engines including simi trucks. They both works the same way. You can clean them and they will still work if there is a soot build up. The soot blocks up the small port holes,that's when the code mostly will appear. Get sm acetone or carb spray or rubbing alcohol and wipe it off good and let it dry. Then install it back. Take your negative battery cable off to reset the code. Make sure you always check your wiring harness as well before installing the sensor back because that's a lot of heat that travels through your exhaust and sometimes it will melt your harness and cause a sensor code. Hope this helps..
You said Carbon, Inside your injector? How would that happen? Really. Wow. I think BS. I would use Seafoam spray instead of injector cleaner for the sensor.

@@TD-tb5xk for $500? Don't mind if I do :B
Sensor alone is $600 each, have to be replaced in matching pairs.. I have issues with my SCR throwing a P1C54 Code. Tech at Nissan said it could be a $4,000 SCR, (no diesel techs at any Local Nissan dealers) Nissan corp is no help at all, I have 23,000 miles on truck and they abandoned me. After 3 years.. plan on, if truck last to delete it after warranty, that is not really helping anyway,.. I am just in a survival mode right now as I don't want to keep replacing cheap built Nox Sensors.. every 23,000 miles. And I do not have equipment to put the truck into an Manual Regen mode and reprogram the system, and I don't want to go into limp mode..
@@Funky4me21 That sucks. P1C54 means "Catalyst Missing". Essentially your outlet NOx sensor is seeing a lot of NOx (or DEF), so it thinks your have removed the catalyst. This indicates a severe issue with your DEF dosing or conversion across the catalyst. With such a young vehicle, the most likely culprit is your DEF doser. If they've replaced the sensors, and that did not fix it, then it's unlikely the sensors are the problem. Maybe ask them if they checked the DEF doser, and also check for urea deposits near the DEF injector. If you're in a cold climate, it's also possible your Urea is freezing up.
Can use WD40 ?
if you insist on trying, use something that doesn't have additives (leave residue) and evaporates quickly...such as carb cleaner. don't use that injector cleaner. still probably a waste of time
BMW 335d nox sensor?
Looks like Cummins
Makes me think hmm drill hole near sensor put the cleaner on the sensor then jb weld pipe shut won't have to take sensor out,
that might just work. Drill some more holes so you can clean the sensor. Wrap it up with some metal sheet. These fcking sensors are too expensive to be replaced.
Thank you I save $100 dls
👍
Soaking for 6 hours ,drying for 6 hours. The o2 sensor of my car cost $31 .Thanks
You mean you had to buy a new one?
You must be on drug if you can buy a new one for $31. Toyota wants $210 for one.
This box sensor cost 750$
@@MrN0bady it's not a Nok sensor
Well mine is like gazillion 10000000 dollars.... Lol
Why didn't you cut the original bottle ,you use the whole fluid anyway
It was better for the environment the way he did it..........you know.......
That is not a knock sensor.

If you dip it is better.
Leaving in for 7 hours.
Is it gonna clear my p420 code?
I’d love to know as new one cost a lot
I know this is a bit late, but try replacing your spark plugs. They're cheap and hopefully it'll clear it. I had a '97 cavalier that burnt a plug and replacing it cleared my p420 code. Can't hurt to try.
Only with a 69 injection
I don't think so
I don't think so
Geezer,that's hard work I,ll just buy a replacement
Buying a new one is even harder work as it's more than an average persons weekly wage😁👍
@Andrew M
Your pocket will be happy
Btw: how hard is the work for you to refill the pocket?
For me 2/3 days of work 😬
A replacement is $250
So what am I supposed to do. Not drive my vehicle for 24 hours or more. While the nock sensor is soaking and being cleaned.
A knock sensor is a totally different thing.
But that is correct. You cannot drive your car with the o2 sensor disconnected.
Options: Walk, bicycle, ask a friend to drive you or just don't go anywhere.
These are all better options than complaining on a TH-cam video comment section.
Clean outside first so carbon no go inside
It's not a knock sensor
Is he saying knock sensor?
Yes and they are not knock sensors ... Knock sensors are located by the cams
he's acutally saying Nox Sensor wich is basically a diesel o2 sensor (not really but close enough)
Shit....my o2 sensor cost $250.....going to try this. Well2 see how it gos
and i paid over 400 dollars to get mine replaced, and after just four months, have to do it again it appears!! 😞
@@neryahwilson6499 do it yourself an save money all you need is a claw tool to remove o2 sensor an the sensor itself which you can buy on ebay for low prices..most of them are OEM parts you can find for way cheaper than spending 400$ brother lmk if you need help finding a good deal.
o2 sensors don't sense nitrogen oxide.
Kn0ck sensor are magnetic dumb ass
Why you calling a 02 sensor a knock sensor
@Shinekhuu D Thats helpful. Thanks
Pay attention dingbats! NOX SENSOR!! 🤔
Carburettors don't have carbon in them .
No, but the gas that goes through them contains carbon.
Don't forget to clean the inside of whatever that goes in
Clean the inside of the exhaust pipe or cat? Are you kidding? Surely...
There are different levels of injector cleaners….. this is not the strong enough one to do the job most efficiently
Which are high level injection cleaners
How do you know your NOx sensor is dirty and not just broken?
I’ve heard that if u shake it and it rattles inside then it’s broken, doing my sensors today!
@@elcucuy1959 did it help?
I did that, it is going to fuck up your car. You can buy a new sensor for $30 on line. If you touch the sensor, you fucked up right away.
How about using a torch and just burning all the horseshit the f out? I’d like to try on a crappy car just to see... fire is fire right?
Is a knock sensor or ox sensor your title is wrong
You know you should t touch it with your fingers
Keeps saying knock sensor..... Ad is for oxygen sensor. Car has both.
Turns meth spirit kerosene thiners prepsol degreaser for BBQ the best carb cleaner plenty os stuff all Ur doing is opening for flow the inside is not carbon build-up
You will save a couple of weeks a max month, at the end you need to replace. So two times you will need to dive under your car, and if you break NOx mounting on your cat. then it will be very paunful for your pocket. It wears out not gets dirty.
Tired NOx makes your car hungry for fuel. So playing with this chemicals you not only breathing toxins but also loosing money and poluting:D
It is worth to try anything because these sensors are made of gold judging by their price. I am looking for a bypass to this system because i can't afford to change these sensors all the time. If it is this expensive to save a little polution it is not worth it.
@@Davoodoox1 I'm sure it's too late, but have you ever checked out Rock auto parts? They had about 15 different priced sensors for my car, from $34 to over $150.
@@bigredc222 I made a motor optimization (tuning with computer) and AdBlue OFF a couple of days ago and the car runs like new and i will never have to bother with AdBlue correlated problems again. I am super happy and amazed how well a car can actually function when no crap system is in the way.
@@Davoodoox1 Are you saying you have a diesel and figured out a way to get it to run without AdBlue?
What about when it comes time to get your yearly emission test?
@@bigredc222 No problem with emission testing. Then all the other diesels without AdBlue would fail too??? If you remove the DPF then you have problem with emission testing. Yes a simple programmin called AdBlue OFF was done and car runs like new.

Just replace it bro... ✌️
confused knock sensor....... w O2........it seems
He has a NOx sensor there. Different from knock and O2.
Why do you keep calling it a knock sensor...it's an 02 sensor.
O2 sensor is for gas cars and nox sensors are for most diesel engines including simi trucks.
They both works the same way. You can clean them and they will still work if there is a soot build up. The soot blocks up the small port holes,that's when the code mostly will appear. Get sm acetone or carb spray or rubbing alcohol and wipe it off good and let it dry. Then install it back. Take your negative battery cable off to reset the code. Make sure you always check your wiring harness as well before installing the sensor back because that's a lot of heat that travels through your exhaust and sometimes it will melt your harness and cause a sensor code. Hope this helps..
You said Carbon, Inside your injector? How would that happen? Really. Wow. I think BS. I would use Seafoam spray instead of injector cleaner for the sensor.
