HOW to Clean O2 Sensors [For FREE] 

"The water might be too hot?" LOL. Those sensors have heating that makes them go over 600F.

A+ for effort and clear video. Placebo effect though.............cold water isn't going to clean carbon deposits.

Get the water hot then let them soak for 7 hours, when the water will cool down in under 30 minutes 😂

A 50-50 mix of concentrated Simple Green and water. If you soak carboned up pistons in it they come out looking new in about 30 minutes. I just did this for 8 pistons for my 350 Chevy rebuild. Still had to clean the ring lands, but it even made that easier.

Just spray them with carburetor cleaner and you're good to go

You should soak them in gas for 12-24 hours, gas dissipates fast when taken out so no left over fluid is in your sensor, gas also eats away carbon deposits

Great collection of the hazardous waste in this one!

Wow seems very intresting i never tried cleaning sensors before i just replaced them whenever they goes bad.

If you're cleaning the sensor as part of your maintenance great but if you're doing it because your having a problem with your sensor? Before attempting to clean it, test it with a multimeter to make sure it's not faulty. No point in cleaning a failing sensor.

Dang! No carbs are coming out of my sensor, only protein. I'm disappointed.

Best way I found out is leave it in 1/4 of hot boiling water for few minutes also don't forget to spray some kitchen cleaning products to the sensor that will help to loosen the junk inside then stirring the sensor in the hot water every 10 to 20 seconds then u will see how much craps comes out with out damaging the sensor ,then keep changing the water till there is no more junks comes out after that dry it with heat gun or just hair dryer should work then see the results

Or you can spray and soak with brake cleaner for 5 minutes then clean up the outsides also with a soft wire wheel or brush.

Thank you for your time and service. Straight to the point

Great video, really helpful, thanks from UK.

What exactly did you spray onto the sensor? Water or carb cleaner or isopropyl alcohol?

What did you put in the spray bottle?

I soaked in gasoline for 12 hours, agitated it (every 2 hours), than let it air dry. after driving car for a week, check engine light was gone. came back 4 months later, didn't matter, pass emissions before it came back.

what about multipupose electronic cleaner/duster compressed air?

Quick question? Can I clean them every 15000 miles instead of doing oil changes or any preventive maintenance? Can I add bleach to the watter?

I recommend dipping them in some carb cleaner or straight-up gasoline but all it does is slap a bandage on an open wound. Its just buying you a couple more miles nothing more, you should just buy some new ones.

I usually keep throttle body cleaner around as the throttle body gets dirty often. I'd probably use that to clean the o2 sensors....or something better than water. But its still a good video. I prefer cleaning first before buying new parts.

what is the liquid in the spray container

Will high tess gas help remove carbon buld up

You could use a water pick instead of a spray bottle. All you need is an extension cord.

thank you very much for your information friend, may God bless you always a big hug 👍👌🙏😇💯

How about vinegar?

Just dip them in boiling water while pouring baking soda on them for a couple minutes, dry them off and reinstall them, works and will pass smog

What type of solution you put in the spray bottle? Would alcohol work? Thx for your video.

Not bad, not great, but not bad. Make another one...the outcome? Did it work???

Thats what I was gonna say boiling water never tops about 250 F the exhaust is 1,000F plus

Try soaking in gasoline if no carb cleaner is available

Thankyou for going to the effort of making the video..and the smartass comments gave me a bit of a giggle...My car has been intermittently surging for a few weeks now, and I finally sat down to read the DTCs my scan tool logged tonight. Not just read them but actually decide to fix them...given that my Oxygen sensor hasnt worked for a month and I have zero patience, Im going to hit the damn thing with 80 grit sandpaper then tie it to a piece of string and smash it on the ground a few dozen times to loosen 'whatever the Hell I find inside it'..if it doesnt work after that I at least get to amuse myself while Im trying to fix it. Its 50 bux to replace it for my car and I want my moneys worth. Cheers for the vid...Im justbeing silly..Im sick of working on my car..been doing it for 2 mnths straight now every day.. FYI Im actually not going to use sandpaper or string....but I want to ..;)

What do you have in the pink spray bottle

I've heard about how some have used ultra sonic cleaners.however I believe that the best thing to do is replace them..especially if the vehicle has 100 thousand or more miles..like spark plugs.the go bad

I used carburetor cleaner on mine and they’re perfect now, no more check engine light

thanks

I used carburettor cleaner pour some in cup and put the censor just for a few minutes, it works perfectly for me.

Nice domo. , How many sensors are there in Tahoe 2007 ,

2005 honda accord. Bank 1 sensor 2 code. Disconnected both and have them soaking in gas for the next six hours, all the time I have today. Thought I’d try soaking them as opposed to spending $60.00 CDN on a new one. I dont understand how soaking them in room temperature water could possibly do anything. Who taught you that? Did it work?

Hey bro where I find the oxigen sensor on 07 Suzuki boulevard !??? Please helpme!!!!

I’m running the new Shell Paleo Premium no carb gas. No buildup on sensors and the windows roll up real fast.

Would using ultrasound make for a better cleaning of the sensor ???

Great video and info but I'm not gonna waste my time and hot water is not a very good solution. Carb cleaner is cheap and easy to use plus it will save allot of time instead of using hot water and waiting seven to eight hours.

He's concerned about "the carbs" so uses a big plastic bag to go into landfill. That Swedish teenager has a lot to answer for.

Just heat up the sensor with a torch and put it in hot water the carbon comes off in seconds

Lemon juice works great as a solvent cleaner

Thanks.

I use a carbohydrate calculation app., on my phone! The application lets me know if my O2 sensors need carbs or protein. Thus, not letting them get too carbed up! It generally, saves me a lot of time from cleaning O2 sensors!

You can test this method by soaking an exhaust valve with carbon buildup in water and see what happens to the carbon, Nothing! carbon is a deposit from unburned hydrocarbons, it is not water soluble. Heat is the only way to clean and the cat converter is not running hot enough to burn off the carbon. In the lab we tested the functionality at 1100ºC for durability. Water is not the way to go.

You don't want your oxygen sensor(s) to have too many carbs, it's bad for your car's health. 😂

Good that there were no carbs in the oxygen sensor since im on a low carb diet.

They have sprays you can use for that

you could also put your whole car into the water for a night or two ... complete waste of time and effort this one ...

What chemicals u clean with...?

Please tell me what kind of liquid you spray on the oxygen sensor to them, please answer me right

Does it matter if I get the same model sensor but my check engine is still on

Someone i know told me to place a bad one in the place it goes in the down stream part of the pipe or just plug it off and plug in a good one and hang it on the frame rail ( sounds super crazy ! ) I did it and it works great and the check engine light went out... crazy but it will works, it did for me anyway.

I wonder if vinegar works also?

Catalyst system efficiency below threshold Bank 2 what is mean

Sounds like to me he's just learning how to clean a o2 sensor . Lol

O2 sensors don't contain "carbs". There may be carbon buildup, but plain water won't remove that, especially since it's been baked on for thousands of hours at very high temperatures. If your oxygen sensors need replacing, they need replacing. (I wonder if this guy cleans his platinum plugs when they have 50,000 miles on them...)

No Carbs came out cause’ he just cleaned it Dummies. Good Job bro 👏

I soaked my toyota vitz 2007 upstream oxygen sensor in hot water for around an hour. Then i spray it with wd 40. When i install back the sensor then its giving p0135 code which shows heater element fault in oxygen sensor. Don't know what happend with the sensor. Any idea?

I use vinegar straight. Does a great job on a soak.

Wonder if ultrasonic cleaner work.

What type of comical to use to clean 02 sensors

So does the water stay hot for 6 hrs?

Gas wont hurt o2 sensors,think about it,the excess gas comes from the motor through your exhaust which it hits both of the o2 sensors as it passes

Is this same guy that "restored" an old acoustic guitar he claimed to have found in the woods? Then proceeded to absolutely demolish some poor old flattop, lol.

Oven cleaner,'kills carbs' !

Even boiling water doesn’t reach the temperature of the exhaust 🤣🤣🤣🤣

so you are sparying them with water?

Citric acid water and use compressed air

What are the symptoms if this sensor failing?

If the preheater in the sensor is failing, this will not help. Also depending on you mileage, sensors our limited with milage.

AND the check engine dis@pear??

Help, iv got a Weber twin 45 in my lambda sensor

So do I use jus hot water ... Nothin else ??

Clean the countertop too it's to much toothpaste .. 😆there

Cant i use kerosene for cleaning...

Carb cleaner?

I went Keto. No carbs. Lost 15 pounds in 3 months. I recommend it.

carbs as in carburetors?

Why not soak in redline or clean with a carb cleaner or gas

OMG thanks a million, you saved me almost $800

the fingers of your left hand appear to be whitened !! : D: D But the sensor was amazingly beautiful, shining like a black hole: D

You left out what to put in the spray bottle, am inportant step!

I used a wire brush to clean the outside, took 5 minutes, then left them to soak in strong bleach over night, they looked like brand new in the morning.

Carbs?

just wondering .... can I drill a hole just opposite of the sensor in the the exhaust pipe and spray the sensor clean with carb cleaner as needed ? Filling the hole in the exhaust pipe with self tapping metal screw.

If I took the trouble to remove the sensors for cleaning, I would soak them overnight (10-12 hours) in gasoline and then reinstall them.

It's not the end which becomes the problem it's the wires inside the housing which go first. Unless your running rich for carbon build up.

No way he is serious 😂

“Don’t put them in a microwave” yeah no shot lmfao bro had no idea what he was talking about the entire video.

170k before I needed a new one

THERE IS A MAINTENANCE INTERVAL FOR THOSE O2 CENSORS 100K MILES U NEED TO REPLACE IT....

Carbs???

I use CLR and it worked just fine overnight

Your good

just a joke, LOL I got you!
