Superb video - many thanks! Made a non- car mechanic understand the way it works. I am an electrical engineer and this is a totally different world to me ;o)
Hi Sir, this is one of the greatest tutorials ever seen! it's amazing to know that there's an outside air in the process! that's just amazing, thank you for your effort. great video +1
These are excellent videos. I have been drinking them up for the last hour, the entire batch except two of them thus far. Wow, I am just pondering how much work went into each one and where the cool graphics came from to begin with.
This is really wonderful and amazing presentation. It has a tremendous educational and also simply aesthetic value. I can watch such videos on hours. Thank you for your time and commitment to produce this animation. It is not so easy as some could have thought.
Great video explanation on how and what an oxygen sensor actually does! I understood the purpose of the sensors but the science of how and what they actually do was a bit of a mystery to me, this video was both interesting and very informative. Nice job! Thank you for posting.
I wish I had seen this video a year ago. Would of saved me thousands of dollars. Been to 2 garages and told they could not figure it out! I am no mechanic by any stretch of your wildest imagine, but have figured out my problem. Exhaust leak from exhaust manifold connection to exhaust pipe before o2 sensor on drivers side. 93 ford ranger xlt 4x44.0L
Very interesting. I wondered how those things worked. The layers were a little confusing as to where they were. The Platinum wasn't labeled until after it was talked about and it showed two different colors for the platinum once the meter was shown.
A very informative video; thank you. You might go the next step and show how to test the sensor with pros and cons of different methods eg DIY and professional methods.
The easiest way to test an Oxygen Sensor is to send either Positive or Negative voltage through the Signal Wire Utilizing the Cars Battery. Just use your body as a Resistor when testing using Positive Voltage. Real Fixes Real fast, shows how to test the Oxygen Sensor utilizing this Methodology.
At 2:45 when it said " The difference in concentration of oxygen molecules in the exhaust gas and the ambient air drives the oxygen ions from higher to lower concentration." Is outside air the higher concentration? Thanks! This video is very well done by the way. It really helped my understanding.
I know this is 7 years later, but yes the higher concentration of oxygen molecules would be in the ambient air, since the oxygen inside the exhaust was mostly used up during combustion.
O2 sensor in my bullet bs6 bike is defected due to hit by other bike so the sensor light is lit but sometimes not lit will it be ok without changing it? how will it effect to my bike?
Could you explain ware it gets the air from? Like a signal reference from the intake or ambient air temp sensor? Or how or ware does it get the air to the sensors
Excellent video. Very clear and detailed. Just one question: What exactly does rich or lean mean? Rich=high voltage=low ratio of outside O2 to exhaust O2=not full combustion of gas in cylinders? Is this correct?
One thing It didn't say but its pretty much common sense is when the PCM receives a lean signal around .1 volt it grounds the injectors to stay on longer. When it receives a rich signal around .9 volts it shortens the time the injectors come on.
On the down stream O2 Sensor, I am not getting any trim... The voltage varies but the trim is steady. I have changed the sensor twice. Id on get knock senor activity at over 4,000 RPM's 2005 Mazda 3 any thoughts?
EXCELLENT VIDEO EXPALINED VERY CLEARLY AND VERY INFORMATIVE - The mixture on your car could be made to run very lean if a resistor was placed inline with one of the leads coming from it, this would reduce the voltage and the ecu would run the car lean :) great for high emission engines that fail at the dreaded mot
not when its on idle (like when testing). And if it is running rich, the resistor would only drop it slightly to make it look like its juuust right. ecu tells the testing equipment everything it peachy and you get the green light.
Didnt those bullshit plug in power chips from back in the day do the opposite? By fooling the ecu that it was lean n making the car run richer..... for £125?
theravedaddy i think you need to increase the voltage to fool the system into thinking its ritch so the injectors run a bit leaner, that should give better economy, but be carefull not to go too lean or its bye bye pistons and plugs, there are some aftermarket products that should do the trick. If its a single wire o2 sensor then you could probably DIY with a voltage reg, a trimpot and AA battery
Bloody el that's complicated but I understand now thanks!! I have a P0299 turbo underboost code due to a split intercooler hose to the throttle body and I have an O2 low voltage DTC....wonder if the two are correlated? Any ideas clever mechanics out there??
From other sources on the internet I have found that the temperature to which the sensor has to be heated to operate is 600F. Wow! That's hot. Don't park over a pile of leaves.
I still don’t understand it, how does it know the difference between rich and Stoich? I mean since both stoich and rich use up all the oxygen in the exhaust, then essentially there is no difference in the makeup of the exhaust for these two conditions, unless stoich is defined as still having some percentage of oxygen in the exhaust.
The ONLY video on youtube that explains the actual principle and working behind the O2 sensor
A 100 page book couldn't have explained the functioning of O2 sensor as clearly as does this 4 minute video. Thanks for sharing.
Superb video - many thanks! Made a non- car mechanic understand the way it works. I am an electrical engineer and this is a totally different world to me ;o)
OMG YES! Thank you for providing exactly what I need to understand what's going on under the hood!
I make these at Denso the process is very unique from start to finish
Sir...I m watching this for preparing interview in denso
This video helped me understand the function of oxygen sensors x100 better. Thank you!

Excellent, a picture is worth a thousand words. I can now understand why the Sensor votage is oscillating and not a steady DC.
Very clever these scientists/engineers.
Air is life.
thanks - this is brilliantly informative and brings the subject to life
so well
Thank you your student is gaining more knowledge
outstanding! I finally understand.........and I enjoy the format: visual and reading/ while I have another video Im listening to
Fantastic video. Many thanks.
James Buttery: I agree! The steady beat of the music also made me concentrate better
Bravo, great explanation through superb animation....first video and here you earn a new subscriber
chemistry, physics, and gear heads. my favorite combination. excellent video. now i know why my o2 sensors are throwing a code.
Why are they throwing a code?
best explanation please can u make for other sensors how they work mechanism
great explanation on the operation of an o2 sensor

Was it just on my side or did the music only start at the end of the video?
Other than that, this video is very informative.
Terrific graphic motion...and nice background music..Thanks.
EXCELLENT THOROUGH, CONCISE, GRAPHICAL /TEXT Presentation ... Tom Jones, DDS... New Orleans
great video, i don't know why all the criticism not like these people making any video themselves.
very helpfull video i like it. try to upload more videos like that related to EFI system
Thanks that's how video b make to understand better ..I didn't get low voltage work now I do thanks again
At 2:45 when it said " The difference in concentration of oxygen molecules in the exhaust gas and the ambient air drives the oxygen ions from higher to lower concentration." Is outside air the higher concentration?

Excellent ASE A1, L1 study material.
so, the heater circuit, is it on the entire time, not just used at startup to warm up the sensor ?
Thank you for making me less stupid.
Very Very Clear one..... Thanks a lot for sharing....,
Easily understood the video...expecting more videos from you ..
excellent
just got a check engine light yesterday on my 98 prelude, gotta change the the o2 sensor asap
Great content ! I expected something about post cat sensor though
Good video! Thanks so much 😊
wonderful video ... hats off !
i am every clear with your Video guide . could u make more video about vehicle ? i hope u can share your video to help improve about knowledge? thanks
I like this video 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Zirconium dioxide
Thanks so much for a well illustrated introduction.
awesome channel
love your videos
best video tht i have ever seen
Im glad to see this
This is a great vid. I can't fathom why there are 203 down votes.
Is it posible to bypass the connection of sensor temporarily until there is a replacement. Old cars has no sensors and last for decades.
Very good video. Thank you.
O2 sensor in my bullet bs6 bike is defected due to hit by other bike so the sensor light is lit but sometimes not lit will it be ok without changing it? how will it effect to my bike?
very nice its easy to understand how the engine works thanks.
Keep watching. Most welcome
Could you explain ware it gets the air from? Like a signal reference from the intake or ambient air temp sensor? Or how or ware does it get the air to the sensors
Great video. Thank you.
Thank you for posting.
Does this require to be cleaned at regular interval as the mass air flow sensor please?
Excellent video. Very clear and detailed. Just one question: What exactly does rich or lean mean?
Rich=high voltage=low ratio of outside O2 to exhaust O2=not full combustion of gas in cylinders?
Is this correct?
Rich means that the fuel to air mixture has more fuel than the specified operating value and lean means the air is more than the specified value.
Great video! Now if I could only find out why my RX300 hates knock off brands like Kwiksen...
Super video very educational!!
thank for your information
Great visual explanation!!
Which sensor should be the first to be checked for cleaning, or replacement?
how does oxygen flow electrons at a different rate depending on the concentration of oxygen in the exhaust gas?
One thing It didn't say but its pretty much common sense is when the PCM receives a lean signal around .1 volt it grounds the injectors to stay on longer. When it receives a rich signal around .9 volts it shortens the time the injectors come on.
No sound?
God bless you dear sir
AWESOME Graphics! Thank you.
excellent video ,,, thank you !
this was great, thanks!
What is the normal range? How much percents?
excellent, Love it, thanks!!
nice video. you show the current flowing from positive to negative in the external circuit. wouldn't it be the opposite? thanks
Great video, now I know why used cars are worthless and why manufacturers are going bankrupt.
On the down stream O2 Sensor, I am not getting any trim... The voltage varies but the trim is steady. I have changed the sensor twice. Id on get knock senor activity at over 4,000 RPM's 2005 Mazda 3 any thoughts?
so if second o2 sensor monitors work of catalytic converter,he dont afect on fuel-air mixture ? he s hhere just to signal a bad catalytic converter ?
Good Explaination
good video!
cool video!
Brilliantly effective!!
More like defective, o2 sensors fuck everything up
love it very easy to learn like that
Excellente video ,,,, !!!
Very very good vedio
great video

Sir ek intake manifold ka animation b dal do
Description/explanation for the sensor before the catalytic converter is not correct; nowadays in this position a measuring sensor is used.
The videos are great I would recommend better audio maybe a human reading them?
thank you good disruption of upper and down 02 sensor , do you have any more helpful videos
Nice inference 😊
great videos keep up the good work.
From other sources on the internet I have found that the temperature to which the sensor has to be heated to operate is 600F.
Wow! That's hot. Don't park over a pile of leaves.
All I needed to know, let's straight pipe that bad-boy right now
