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.
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.
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.
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.
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.
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
I don't know a thing about cars but soaking them in gas sounds fishy. Reminds me of when I left my spoon in the microwave to help reheat food faster-that didn't turn out too well.
@@JustAHevel i know quite a bit about mechanics and this is what you can do to clean them, I'm not trying to tell anyone to do anything dangerous or that would ruin their car. As a mechanic I have a reputation to uphold for my customers and would never steer someone in the wrong direction
@@JustAHevel he’s right. Gasoline has carbon cleaning detergents in it. Techron and other brands are formulated to remove carbon build up. Soaking them in gasoline will work, however there are less stinking alternatives, such as throttle body cleaner which, just like gasoline will vaporize quickly but without leaving residue behind. B12 (the fuel additive, not the vitamin) in the pour bottle, not the aerosol bottle, offers the least mess. You’re able to soak it in there and it’ll dissipate all of the carbon.
You've wasted the time of over 14,000 viewers. Water doesn't remove carbon deposits. These sensors don't even need cleaned anyway. They either work or they don't.
Exactly why I didn’t listen to this guy and Im just a diyer. Nothing wrong with buying two sensors from denso like I did for the price of one autozone sensor.🤷🏽♂️
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 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.
Ren - Water at 250 degrees is called "steam". Boiling point being 212. And when engines run about 195, inside cylinders about 450, how does exhaust get to 1,000 F ?
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.

Water? They'll be dirty in one minute after the car runs. Gasoline in a cup, soak them. Gas fumes are flammable! 💥 Gloves, eye protection. Water? What a waste. It'll clean them but why bother?
So that guy thinks he can get greace and dirt out of that sensor with only water? That's maximum 70 degrees Celsius 😅 greace is water-repellent Einstein...
He just has to find a way to make a video about o2 sensor no matter what. I see no point and no science behind this video. I really don't think he understands how an o2 sensor works, or the chemical properties of carbon or water.
Might as well try to see if it works at a cost of over $1200.00. I would soak it in a better cleaner though.. they are suppose to be replaced in pairs or supposedly the ECM will still give out codes..
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.
If you soak them in toilet bowl cleaner for 15 minutes, you will be able to clean the inside and out. You'll have to use compressed air to get the liquid out after cleaning.
Deep them in petrol overnight job done. Just make sure doesn’t go on the wires.. you will see how much carbon will come out.. done mine only for 20mints didn’t have time to do it longer is been perfect 7 thousand miles since don’t it..
Waste of time, 02 sensors only have a real world life span of 100k miles. And the most common failure is the heating element burns out. They pay for themselves with increased fuel economy of fresh sensors.
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...)

Spraying any sort of chemical on O2 sensors to "clean them" is a total waste of time and effort. NO chemical will remove the deposits that are inside the little holes. The problem is the other hard deposits inside the little holes, NOT the soft carbon on the outside! BEST way to clean O2 sensors is to heat the hell out of the tip that is inside the exhaust pipe to a bright/cherry red color. That is about 900F to 1000F. This will burn off most all of the deposits and the sensor will work again about 80% of the time. I have been doing this for many years. Works great and really is almost free to do. Just be very careful not to burn the wires or yourself!
