HOW to Clean O2 Sensors [For FREE]

Easiest way to clean O2 oxygen sensors

[pjffxwx]

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

"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 water isn't going to clean carbon deposits.

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.

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

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

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

[laragreene]

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.

[daviderhahon]

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

[paulsmith.]

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

[yobpela]

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.

Great collection of the hazardous waste in this one!

[dandiy]

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. 😂

[locknload]

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.

[joshr]

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.

[jeffspeer]

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

[eternallearner]

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.
