Car-care nut,I am an auto-mechanic, specifically,a Toyota specialist.I operate an auto-workshop here in Lagos Nigeria.Since I came in contact with you on TH-cam,I have tremendous respect for your detailed, not only to your DIY viewers,but also to practicing mechanics. I must confess,that you are a born teacher. I am your great fan & I will never stop watching your videos. God bless you forever.
Can you please help me. How would you disconnect the plug behind the block on Bank 2 sensor 1. The plug for 02 sensor is tucked behind the block and I can't get both hands back there to push the clip and pull the wires to disconnect the connection
This guy is the best. Absolute master mechanic generously sharing his technical knowledge, what a legend. I've spent so long trying to figure out an issue I've had and now i know it's a vacuum leak. Thank you from the bottom of my heart.
Good job AMD. I taught automotive in the community college system for 15 years and your explanation hit the mark. A good educator makes complicated things easier to understand, not harder to understand.
Thanks again for your excellent videos. Your not just a master mechanic but also an excellent instructor. I’m a retired vocational instructor with 26 years in the classroom and before that 18 years as a union tradesman. It shows how much you love your trade and that makes the best instructors. Thanks again for sharing your skills. God bless you.
Owned a 2011 Prius and now a 2001 Camry with 113000 miles on it and your videos have been extremely valuable. Thank you for taking the time to make all of these quality videos! May the Lord bless you and keep you as well!
AMD, you have a talent of explaining complex topic in a easy, organized way using plain English. I been DiY shadetree mechanic for a while and you're the first person who can explain the emission system and how it works that actually makes sense. Thank you posting such a useful info.

Excellent teacher, we need more educators like you! 5 STARS "Better than a thousand days of diligent study is one day with a great teacher." Thank You!
This is definitely my favorite automotive youtube channel. You know your stuff and you know how to explain it in simple, layman's terms. Excellent job all the way around.
I have always been curious how auto parts work, not just how to install them but to know the physiology about them. I am so happy I came across your page. I will be a lifelong follower of your channel and I appreciate you breaking down logic for people like myself who are not born mechanically inclined.
Another excellent instructional video. Now, everyone starting out should see this, and remember the main part..... O2 getting stuck some brake fluid --- or your choice of solvent.. but this also works for any bolt stuck. Don't force it, spray ( apply ) and then turn it back in and wait. Heck even if it takes you 30 mins, you will never brake a bolt while removing it.
AMD. Your videos are awsome. Here is an interesting one. 1 the car,mentioned, is not a toyota. Same type of system. 05 nissan w/ 2.5 L . Had a lean code. Changed A/F sensor. 2weeks later same code. Found small cracks on exhaust/catalyst manifold. I replaced. Same code. Scan tool readings all in spec. Up and downstream readings.I,finally, changed the downstream sensor per professional advice. No more codes or problems. 62 year tech and I'm still in the business.
I spelled it wrong. I'm a 62 year old tech. Been in the business starting in my teens. AMD. Great videos.🎉 I wish my,fellow, technicians would watch your videos. You have so much to offer.They think they know everything. Experience is the key. When it comes down to it, self taught is the only way,even,with the right information and schooling. And maybe advice from some old timers. I call it learning experience. We all have made mistakes and we all know we won't do that mistake again. Example. Wheel bearing with ABS trigger ring in the seal. New guy put bearing in a car, activated an ABS code. He put the bearing in backwards. He won't do that again. Learning experience.
Thanks, dude. This cleared up so much for me. I got a P1133 on my 1999 Toyota Camry LE, and this video explained a lot. By the way, I will end this with the same thing you said, as I always use the same when I write. God bless and keep you and your whole household, brother!
I love the in depth explanation of this and how you personify the sensors & the ECM on how they communicate with each other. It gives us a clear picture on the operation of the engine. Thank you so much!
Thank you so much for helping me be a better learning mechanic. I am 42 and doing a double studying school in Germany ( Kfz Mechatroniker Ausbildung ) . 🙏🙏
Another awesome video. O2 sensors well explained. I loved the analogy of the O2 sensor being the angry mean unhappy guy doing the QC. The brake fluid trick to remove stuck O2 sensor is priceless.👌
Yes ! Little 'TRICKS" like the Brake Fluid are a Hard lesson that save you SO much Time and Angry energy wasted that come from an Experienced Mechanic ! I'm a Retired EE,and spent 7 years in the Army as an Generator Repairman 52 Delta. But OBD2 didn't exist then,and his method of teaching is VERY WELL Done !
I am Toyota Lube Tech here, starting to learn diagnosis and all. You are helping me a lot with basic knowledge i need to keep on learning more. thank you very much for your videos. I had watched a lot a lot of your videos, i just have to remember to thumb up. Will thumb up from now on. Thanks again!
I've watched a lot of your videos and I love how you are actually teaching people how to actually fix and do mechanical work on vehicles thank you and I look forward to seeing some more of your videos
Wow...as an old school DIY mechanic...the Toyota dealership will be getting my money...except for oil and filter changes...now I feel better. My 2020 Camry...a very complex mechanical modern marvel. However...I have full trust in the reliability and quality of Toyotas. My former 2005 Camry...an engineering marvel...unbelievable!
Thanks A lot for your advice, i'm Ugandan, computer diagnostics as a first resort IS NOT really a thing here, we mostly listen to the sounds of everything to do with the engine mostly, i've literally tuned myself to telling the slightest change... but just by watching your videos for clear advice, i managed to slowly restore my 2azfe engine to perfection, not even a check engine light!! Yay! thanks A lot, coz our mechanics have a LOUSY relationship with the truth, its ALL about making you a frequent customer, the moment you enter the garage here, youre looked as a cash cow ready to be milked of $$$$$!!! God Bless you! Worked on it at home with help from a military mechanic (I think the Japanese made ones are actually differently built, this was a 2001 ipsum i was working on, most of the camry issues didnt apply) THANKS AGAIN!
I must say I'm never disappointed with your info. Easy-to-follow. I'm sure you're making good money doing this but you are helping people that completely hate taking there stuff to the dealer. Thanks for all the help
I love your explanation of the O2/AFR operation as a "tango". That's the most understandable and least "Dry" presentation that I've seen for it. Thanks!
First video I’ve seen of yours but I knew in less than 10 you were a good instructor! Killer analogies, light bulbs coming on everywhere. It won’t help me find the 2 bolts lost lol but it will pay down the road. Thank you
While this is over two years old, it is still EXCELLENT information. Very well done. Thanks AMD. I love your videos. If you were closer to me you would be doing all the work on my 2005 LX 470. It's a great vehicle that is just beginning to show its age. The radiator was changed about 3 months ago and I just changed the two upstream oxygen sensors with oem DENSO sensors I purchased from Amazon for half of the cost as the local auto parts store.
It's so funny to hear the tandem action (aka tandem dance) of the computer and oxygen sensor - rich, lean, rich, lean..and so producing the peaks and troughs in the graph.. AMD, you are an amazing professor in my eyes. Much Love, God Bless!
Excellent, thank you! There's nothing better than listening to someone, that knows their shit so well that they are able to explain a somewhat complicated concept in terms that are so easy to understand that its actually enjoyable to listen to then talk about damn O2 sensors in a car!
Thank you, I now have an understanding of these sensors. Very professionally done, and relatable for a novice. My 2001 highlander has a code for one of these. Once I use scanner again...I will know which one to replace. Since there are four...you saved me time and money.
Having watched many auto videos, your presentation of these control elements is the best explanation of sensors that I have found. You did a good job, thank you.
Wow. What a great video. I learned so much from this. Having battled a "lean bank one" issue, this really cleared up how the sensors play into that code.
Oh man, thank you! Been trying to pin down a sporadic misfire that is highly weather/temperature sensitive; only happens when it's cooler outside on an '07 5.7 Tundra. After doing the usual tune up remedies and it still happens, I'm going through the OBD readings and had no reference to what is 'normal' for this engine. Great info when it was needed!!
Thank you for all this wonderful information you provide in your videos, you are a diamond in the rough in the world of automotive repair! I am learning so much watching your channel that I should put I graduated school of The CarCareNut on my resume. 😃
I learned about these when diagnosing a P1133 code on an d ES300. I could see one sensor fluctuating around 0.660 volts from 0.645 to 0.685 and the other staying right at 0.660 volts. It took me 3 orders to get the right sensor, one from the dealership which turned out to be the oxygen sensor, one from Walmart which looked like a suspect counterfeit, and finally the correct one from advanced auto.
This is the best explanation of the workings of the fuel trims that I’ve ever heard. It’s put in such a way that it completely takes the mystery out of these much overlooked components. Excellent video, thanks for sharing you knowledge and skill. I’m now subscribed.
Thank you so much, the seized sensor was exactly as you described. The auto shop quoted me 400$ to remove it but it came off with 5 mins and some brake fluid
Hi AMD! I own a '03 Camry and are a DIY guy. I have been watching some of your videos and they are excellent. Your way to explain things is very easy to follow and understand. Thank you and keep your great job. Many blessings!
An older video but I feel like I spent 1,000 for a college course and gained more knowledge about reading codes and sensors. I replaced one and wished it came out as easy as yours did. After I learned a good tap or two on the wrench may shock the sensor and help break it's rusted bond
Perfect time for me to see this. My A/F sensor on a 2001 Camry failed. The computer threw a blinking check engine light. I towed the car to my Toyota dealer for repair. Both sensors were replaced. After the repair the car ran okay when cold but misfired when hot. I delayed seeking service and tried not to drive with a hot engine. After a few days the misfires stopped. I assume that the computer just needed time to learn from the new sensors.
lol....."Loose nut behind the wheel gets the warm glow of a check engine light" cracked me up! I have two Prius hybrids and notice the ICE engine sometimes comes on even though the traction batteries aren't low....so must be trying to get itself to go to the happy state of a closed loop. Very interesting video and helps me understand some of the sensors I'm seeing when under the hood and under the car!!
Excellent explanation. Many parts stores online or local play fast and loose with the terms O2 sensors and A/F sensors. I really couldn't make sense of it. This is perfect video
This man really know how to exllain all that mechanical mix ....thats the same dance happening between my MAF and 02 sensors right now ...in my case its the 02 that needs changing..
Great content. If I may, I have a tip that has served me well for many years. Any time I get a vehicle that has North of 80k miles. I like to change the O2 sensors out for new and clean the MAF sensor. In a perfect world, if everything is running as it should and the driving habits of the previous owner were optimal, this likely wouldn't be necessary. What I find is after doing this the engine simply runs better and often regains some mileage that may have been lost. It can be a PITA to get the O2 sensors out but it's worth it.
In just three years, the McDonald's dollar menu has undergone a five-fold transformation - it's now the five dollar menu! The video seems to have been captured around the time you left the dealership, with the Big Blue visible in the background. And now, you've established your own shop-impressive progress!
the Car Care Nut is simply great in making complicated concepts easy! in the end all this makes me enjoy even more driving my Toyota. I'll keep on following you. thank you. Greetings from Italy
I’m glad I saw this video. My ‘01 4Runner got a code for a AF sensor and now I understand a lil more how everything works. Hopefully this fixes the recent sputter it has. Only happens when I’m waiting on a stop light 🤷♂️ I like investigating stuff like this on my runner
Greetings sir. I would like to thank you and commend you for the great work you do. the way you present the content makes it very easy to understand concepts that were difficult for me in school. Be blessed and all the best in all your work.

Hello sir,
Pls where is your shop located in Lagos?
Retired dealer tech here, I hope people appreciate how hard you are working to explain this. I sent a link to my sons, this is very well done.
Thank you my brother!
I've just started watching but am looking forward to it from your comment alone....
Good stuffs 👍
@@TheCarCareNut is it need to replace it with new one for good reading of fuel and air ratio ?even if old one is good ?
Can you please help me. How would you disconnect the plug behind the block on Bank 2 sensor 1. The plug for 02 sensor is tucked behind the block and I can't get both hands back there to push the clip and pull the wires to disconnect the connection

YES! Agreed!
I have to say, even as a professional oxgen sensor supplier, i am still impressive to your video, you know more about the sensor than me, Nice job !

Thank You!
I envy whoever has the privilege of calling you a "mentor;" you teach very clearly and, most importantly, without glossing over any points.
Great layman breakdown! Other channels left me still scratching my head about AF / O2 sensors. Thanks, sir!!!
Dealerships probably don't like the quality and information content of this video.
This is the best explanation you will find on TH-cam. He explains everything you need to understand and more.
This is definitely my favorite automotive youtube channel. You know your stuff and you know how to explain it in simple, layman's terms. Excellent job all the way around.
Thank you, AMD. You've become an expert teacher for the Global DIY community. May the Lord bless you & keep you for much longer. South Africa

i have a doctorate degree and surprised to find that practical things like these are the things you really need in everyday life!
Hey doc how you doing
Absolutely love this guy! Can't stop watching his videos. Thank you Car Care Nut for doing this. God Bless you!
You do a amazing job on the videos. I was a mechanic for years and I still learn from your videos. Thank you.
You're the best.My Toyota 1999 4Runner just had 02 sensor problem and you explained it very clear.Thanks and keep what you doing .God is with you...
i love this channel. I can’t be the only person without a Toyota here
You are an excellent teacher!😃. I am learning so much. I don’t want to miss a session.Thank you for giving us your knowledge!
I concur. I don't know why I had not come across his channel sooner. Keep up the good work.
Another excellent instructional video. Now, everyone starting out should see this, and remember the main part..... O2 getting stuck some brake fluid --- or your choice of solvent.. but this also works for any bolt stuck. Don't force it, spray ( apply ) and then turn it back in and wait.

boy, what a treasure of info and advice ....also the "visualization", the "ECU Tango dance between MAF and AF" 🥰
Your videos are a must for Toyota owners!
I love the in depth explanation of this and how you personify the sensors & the ECM on how they communicate with each other. It gives us a clear picture on the operation of the engine.

You are an absolute gem to the Toyota community💚
Thank you so much for helping me be a better learning mechanic. I am 42 and doing a double studying school in Germany ( Kfz Mechatroniker Ausbildung ) . 🙏🙏
Your video makes my day brother. Thank you for being what you are.
I love your presentations. I don't know of anyone else that play acts an AF sensor. Definitely make it memorable. Thank you!
Another awesome video. O2 sensors well explained. I loved the analogy of the O2 sensor being the angry mean unhappy guy doing the QC. The brake fluid trick to remove stuck O2 sensor is priceless.👌
Yes ! Little 'TRICKS" like the Brake Fluid are a Hard lesson that save you SO much Time and Angry energy wasted that come from an Experienced Mechanic !
I'm a Retired EE,and spent 7 years in the Army as an Generator Repairman 52 Delta. But OBD2 didn't exist then,and his method of teaching is VERY WELL Done !
I learn something new from every video you do. Appreciate your time and effort.

I had watched a lot a lot of your videos, i just have to remember to thumb up. Will thumb up from now on. Thanks again!
Could have fooled me on there being a difference between O2 and A/F ratio sensors. I’m truly grateful for your insight and can’t wait to learn more!
Don't own a toyota but your excellent channel is a great service.
I've watched a lot of your videos and I love how you are actually teaching people how to actually fix and do mechanical work on vehicles thank you and I look forward to seeing some more of your videos
great tip on using brake fluid on the threads to free up a seized o2 sensor. worked like a charm!
Can it be cleaned without removing it,if which vaccum hose can it be spray into
I am from far away,,but how this man work and teach is very exc😂lent..Easy for me to understand.I learn many many thing .

Exellent the brake fluid really works. Like you said a retired old Toyota mechanic told me the same thing but after i made the damage😃😃
Love this guy, one of the best tutorials I have seen yet.
Adding a drop of brake fluid on the thread saved me, thanks for the tip.
Thanks for the tip about using brake fluid on O2 sensor threads when it's stuck. And the difference between A/F & O2 sensors.
The brake fluid tip worked when I couldn't budge the sensor! Thanks!

I have two Prius hybrids and notice the ICE engine sometimes comes on even though the traction batteries aren't low....so must be trying to get itself to go to the happy state of a closed loop. Very interesting video and helps me understand some of the sensors I'm seeing when under the hood and under the car!!
Excellent explanation. Many parts stores online or local play fast and loose with the terms O2 sensors and A/F sensors. I really couldn't make sense of it. This is perfect video
This man really know how to exllain all that mechanical mix ....thats the same dance happening between my MAF and 02 sensors right now ...in my case its the 02 that needs changing..
Great content. If I may, I have a tip that has served me well for many years. Any time I get a vehicle that has North of 80k miles. I like to change the O2 sensors out for new and clean the MAF sensor. In a perfect world, if everything is running as it should and the driving habits of the previous owner were optimal, this likely wouldn't be necessary. What I find is after doing this the engine simply runs better and often regains some mileage that may have been lost. It can be a PITA to get the O2 sensors out but it's worth it.
Excellent explanation Ahmed. Bravo
Tremendous coaching !
Thanks !!
The LORD bless you brother .
Ahmed it's me AL you did a great job buddy so proud of you
Hey Al! Hope you’re doing well my brother!
@@TheCarCareNut I'm doing good so glad to hear from you..keep up the good work.
Thanks man!
In just three years, the McDonald's dollar menu has undergone a five-fold transformation - it's now the five dollar menu! The video seems to have been captured around the time you left the dealership, with the Big Blue visible in the background. And now, you've established your own shop-impressive progress!
DEAR SIR; PERFECT EXPLAINATIONS, DIRECT TO THE SUBJECT AND SIMPLYFIED. THANKS
Brilliantly explained. I feel I have a much better understanding of what is going on with my car. THANK YOU!
the Car Care Nut is simply great in making complicated concepts easy! in the end all this makes me enjoy even more driving my Toyota. I'll keep on following you. thank you. Greetings from Italy
I totally put on the wrong upstream sensor a year ago. Between this video and the one from Denso, everything makes sense now. Thank you, friend!
I’m glad I saw this video. My ‘01 4Runner got a code for a AF sensor and now I understand a lil more how everything works. Hopefully this fixes the recent sputter it has. Only happens when I’m waiting on a stop light 🤷♂️ I like investigating stuff like this on my runner
I can't thank you enough for this. I have a 2003 and 2004 RAV4 (his n hers) and I just learned a lot. Especially about staying OEM on the A/F. Cheers!
Excellent description. Sometimes nomenclatures get very confusing. You explained it very well! Thank You! 👍
Thank you so much for yet another great lesson. Did a lot of work on my cars after watching your videos.
Great explanations about the O2 sensors and possible troubleshooting that would cause them to throw a code.
I love the brake fluid trick. I have never heard about it in my 40 years of wrenching
Greetings sir. I would like to thank you and commend you for the great work you do. the way you present the content makes it very easy to understand concepts that were difficult for me in school. Be blessed and all the best in all your work.
I have my GS300 Lexus with oxygen sensors problems and the car loose power until I change all those sensors.
Good video, thanks🙂
