You've got a real talent for communicating and simplifying complex topics. This was the best overview of oxygen sensor diagnostics I've ever found.
thanks spelunkerd, I like to simplify things and break them down in segments so most can understand what's going on.
thats exacly what i was thinking
thanks bro

Excellent video,well explained.😊
2019....and after watching this video, I feel like an expert mechanic. Thank you..
Very well done video. I've looked at a lot of videos on O2 sensor diagnostics and this was one of the best. Informative, but not too complex, and practical demonstration.
That was a down to earth explanation of the O2 sensor & very simple ways to test it in a short period of time. THANKS GREAT JOB.
Very informative. This Mechanic himself fully understands the sensor system, and teaches it well. Thank you.
NO, confusion what so ever very good explanation how the 02 works and how to test. always enjoy ur videos thanks and cheeers.
The best video I have seen great job, great info and very clear.
Thanks for you information.
Really like how your videos summarizes stuffs out . Very informative !
Another good video, so as I always suspected an o2 sensor light doesn't always mean a bad sensor. I love getting to real root of the problem! Keep up the good work!
This video is fantastic-great job breaking down concepts with the right amount of detail. I am troubleshooting a P0420 code on my Tacoma and this was super helpful
Big hug from Portugal.Big thanks for your Diy videos, very helpfull.Big help.
Decent video. I watched twice before I checked mine. Your info was right on!
Appreciate it brother.
And here come the HATERZ ...Cmon Big Dawg! Decent Video? Share your video😅😅😅
Your videos are great. Very informative. I've learned so much. Thanks!
Excellent tutorial and perfect timing too. Got a 02 Maxima displaying signs of bad O2 sensor and/or cat. This will help me greatly. Thanks so much!!
Thank you for this upload and for going above and beyond with the drawings. I’m a mechanic myself but it doesn’t fail the amount of ppl asking about their 02 sensors. Although easy to explain to someone else that also speaks the mechanic language, is not so easy trying to convey the whole circuitry and test procedures. Will definitely save and share to at least one guy I currently know that needs it. You got a subscriber also.
Years of experience well explained in a 12 minute video. Solid!
Mi friend you're #1 explaining with not complicated words for an easy understanding and with a great knowledge of this matter, THANK YOU!
Best O2 sensor Video I've found so far, very great explanation and simplified. I have to watch it a couple times and take notes so it stays stuck in my brain lol.
Great explanation! I was able to diagnose and fix my O2 sensor problem. CEL is off, no more P0411 codes, and I’m back on the road! Thank you.
Your use of board diagrams is so helpful-thanx!
This is an impressive video. There was clear communication of the topic and underlying principals, and certainly not too much information. I watched eight videos before this and nothing even came close to your content. Two of those videos were for college level trade school classes (which did have good information but were too drawn out and didn't touch on many other potential issues).
this new found knowledge you gave us is little help whn it comes to taking car to shop they want to throw parts at problem and get paid thanks 4 the vid bro
Thanks a lot man this kind of info is hard to get on the web and ppl like you make it so easy to learn 👍👍👍
Appreciate this Lesson a lot.. 3rd time watching the video today just to refresh my mind and already feeling like an expert 😅 Thanks for sharing knowledge
Bro thank you so much for this! I was able to diagnose after checking everything else with my O2 sensors, testing for power and negative. It was a ground issue all this time so thank you so much and I will make a video to help people out and help them save money like you showed me. Thank you so much God bless you and I will share my knowledge as well. Be safe during these crazy times.
Now thats how you explain stuff in less than 15 mins. Good Vid!
Excellent vid with a lot of good info. It's like a good movie with a deep plot. I'm going to watch it at least one more time to fully understand it all. There's a lot to soak in and digest. Many thanks.
that really simplified all the numbers I'm seeing. thanks. you have real talent. thanks
Very well explained,I was finding it difficult to find out which 02 sensor to replace,after your video,I now know,great video thank you.Subscribed and liked
You are so awesome on the details in your videos 👍👍 so glad you explained about the banks as I kept hearing talk of the bank one and bank two for example but your the first to actually explain it like this and now I have a better understanding of banks. Thanks
you are the most good mechanical man in the world.
Awesome tricks to know the mixture condition, I loved that one when you disconnected the vacuum line and numbers started to decrease, that's a good one!!! Thanks for sharing your great knowledge man!!!
Your instruction is so well organized with perfect visual and very easy to understand explanation. You should become a Professor at the College. I really like all the videos you put out. Thanks a million for sharing your expertise.
Great video, explained a lot more than some others I`ve watched, many thanks
This was a great educational video. Loved it! Thanks
Really really helpful video, thank you so much for putting this together.
Excellent video, great information!
Excellent video. Communication skills are off the chart.
Great job and very informative on this video. By far the best video I have found on this topic. Thanks again.
Learned alot, thanks :-)
Sensitive topic - Great explanation & additionally, your additional tips about the tip heater top sensor tube vignettes. Thanks!
Awesome tutorial dude!
That was a lot of information but after rewinding the video several times i got the hang of it thanks for this video helped alot
Good presentation, your videos are improving, keep up the good work.
Thank You very much ! You'r a Master Teacher and Mecanic man !
Great information and I like how you describe how the parts work on the white board. FYI - I replaced my upstream oxygen sensor four months ago on my 2001 Caravan and the check engine light came on again. The same senor failed and I verified this on the two white wires (heater). The oxygen sensor from Autozone had a one year warranty, so it didn't cost me any money other than my time to replace it again (I did have to pay for the new sensor and I rented the removal tool which I was reimbursed). I showed my two teenage sons how to test the wires so they could see the failed oxygen sensor and the working oxygen sensor.
Glad you like the video, thanks for commenting.
It is a really great video. I learned a lot of important things about o2 sensor. Thank you so much sir.
Great video with very clear explanation. Thank you!
I like your video and the explanation, very accurate. thank you...
Thank you for the information. Appreciate the breakdown! Awesome! You rock! 🤘🤪
Excellent breakdown of testing and function.
Great video Sir...always giving full details on your videos....
Always a good informational journey, thanks!
Very informative. You clearly have a talent. You would make an excellent trade instructor.
Great video! Really helped with understanding O2 sensors. Good info on multimeter & test light uses.
Very well explanation bro,easy to understand, I will trouble shooting my low voltage issue on my o2 sensor, thanks a lot 👍👍👍
very simple and straightforward video. thanks
Thanks mate , great vid and well explained!
I really learned a lot! The diagram helped me understand the circuit.
Why should I listen to someone who uses a multi-meter from Harborfreight?!
Just kidding. I have the exact same multi-meter. I like it. It seems to be a quality tool. I have used mine to repair multiple large appliances for my grandmother.
Thanks for all the great information, brother.
You are a great teacher. Thank you.
Thank you for your videos and sharing your vast knowledge.
good video as all, keep up the good work, un saludo from ontario ca, see you
Excellent video!!! Simply and exactly the info that will help you learn
I hit LIKE before even watching.. I like the way you explain , very informative.. we love you man..thank you
Hats lift up🎩
I like that hood shock! It's so fabulous!
I was getting codes P0171 System LEAN (Bank 1) As well as P0131 Low Voltage Sensor 1 Bank 1. After i watched this video it's clear why as the oxygen sensor is bad. Good video.
Very clear and helpful explanation. Thanks
When you tested the single wire sensor with the voltmeter, the reason it wasn't switching back and forth in voltage was because the sensor was unplugged from the ECM, which created an open loop condition - without the feedback from the sensor, the ECM cannot modulate the pulsewith to switch the mixture rich/lean, so you wouldn't see it at the sensor.
Patrick you didn't need to watch this, you already have this topic wired. Look at the big brain on Patrick you get A on today's test lol
Yes, simple Kirchoff's law, the disconnected one wire sensor could not possible complete a circuit.
He revved the engine which showed a change in sensor output.
Very good video. Very well spoken.
You're close to hit that 1,000,000.00..hope you hit more Dude! I saved this information.
very good video , and a lot of great informations . thank you . now i can diagnosics my o2 sensor by myself .
Like it. Very informative and technical.
Dude your a great teacher man thanks!
Thanks a lot man!! i just checked mine it was driving me carazy and couldn't find why it was wasting a lot of fuel, i'm sure now my o2 sensor is the cause. After checking resistance i saw there was no resistance (olms) on the 2 same colored wires. Thanks alot, i love all your videos!
You did an absolutely fantastic job of presenting the trouble shooting procedure and other pertinent knowledge that I was seeking. Spot on brother. I feel very confident in using the deeper education I just received from you and what I knew prior to watching your video to now locate and correct my current maintenance issue with my vehicle.
Very well done.
Visual aides and all.
Given that no person ever performs flawlessly. My one needs improvement would be to liven up your presentation. Be more charismatic. Or. Get a co-host (I would volunteer to work with you and have extensive experience in such endeavors, and consider editing options. Some music would not be a bad idea. As would some minor graphics as opposed to your current classroom style visual aides.
It really was a great presentation of facts and knowledge. Two thumbs up bud. Thank you for your time and support.
Steven.
Wow!! Thank you for sharing your knowledge!
Thank you. I'm going to come to your videos first when i need car help.
That was the best tutorial I have watched on this subject
Good stuff, thanks, I showed it to my students in New Zealand
wow you made this so clear, thanks you. Simple, I'll give it a go.
Great informative video thank you
It did confuse the hell out of me man but it was a great video to make, a real education, you are obviously a very clever man with electronics, wish you were my best pal. Thanks for making it, take care, best luck. J
Very good video, like your personality.
Great Video
I was looking for the OHM Resistance reading.
My upstream was 0.5 and 0.7 OHM Downstream for the O2 Sensor
Very well mastered subject matter and well explained.excellent overall.i don't have to keep asking my son's help to do the test.
Awesome. Very good explanations.
You are awesome. Such a great teacher. Great videos and diagrams. I have an early 04 F150 I'm having problems with. It runs ok when the ambient temp is cool but when the ambient temp gets in the high 80's and above the engine starts cutting out. I have to turn the truck off coast for a few seconds and crank it back up. Then a few more miles have to repeat. Any knowledge you could share would be awesome.
Thanks a million for making and sharing your videos.
Awesome explanation
Great video. Simply explained.
Man that hair is looking good. Almost like Charlie sheen in Wallstreet. But dude you have taught me SO much. Your a very chill guy who just lays it out in an easy way. I feel like we’d enjoy each other’s company lol
Thx 4 mentioning 2 check the wires since there is alot of heat--a part I've overlooked.
Awesome video easy to follow and made sense
Fantastic thanks. Solved every question I had.
Real solid explanation on these 02's, please do a video on the AFR 02's. Thanks
Best explanation I’ve ever seen!
Thank you. Very helpful and educational.
Very informative thank you for sharing your knowledge.
Thanks for the video! Need to test mine soon!
Excellent video and explanation!
