HOW to Clean O2 Sensors [For FREE]

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

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.

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

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

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.

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

Great collection of the hazardous waste in this one!

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

Great video, really helpful, thanks from UK.

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

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

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.

What did you put in the spray bottle?

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

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

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 ..;)

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

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.
