So I shot this video, edited it for a few hours than realized I misspelled signal on the whiteboard hahah wt..
I didn't even notice until I read it in your comment :) Great video!
After the first two letters on a whiteboard the rest always looks like scribble
Hey i have a question i recently change my civic 2010 o2 sensor bank1 sensor 2 and sensor 1 but the codes are still there before changing the sensors there was code engine coolant temperature sensor malfunction and problem but after i change o2 sensors this code is gone but new codes showed up which is air fuel ratio sensor short range performance problem. And rear air fuel bank 1 sensor 1 circuit out of range high these 2 code are showing with red engine light on scanner but not on dash.
delete it...
@@Cristip i don't have the scanner who can dalete those codes
Good stuff, writing this down for future use. Find the sensor heater and ground with an ohmmeter. On the harness find the heater hot with a test light. Find the harness permanent ground with a test light, it is used by the signal output. Then find the harness switched ground by turning on the engine power and a test light. The remaining harness wire is signal.
Another perfect, easy listening vid. I wish you had more time to do these, you're the perfect informed
moderator.
Excellent description and explanation. Straight to the point without any fluff. Great video
I love the fact that you explain everything so well , you get to the point in a timely fashion, you don't have horrible music , I can hear you perfectly ... thank you for making quality videos that I can use an don't have to skip thru half of it ... thanks again
exactly
Man you explain things so concise and with brevity! I love it! Im subscribing and thanks!
Excellent video - generalized, precise and informative!
As always, great information using real life applications. Keep it going!
Thanks for this video of teaching, you're a smart guy and a great mechanic I'm learning DIY, 4 years now and still much to learn. Thank you sir.
Thanks for great tutorial on oxygen sensor function and wiring, and identifying those wires.
I understand much better, how O2 sensors work and more importantly how to test them. I have a Tacoma truck, no error codes but, the O2 sensor and catalyst registers won't set. That has stumped everyone, no one knew what to do. I spent a ton of money trying to get at least one of the registers fixed and to set. I finally sit down cleared my mind and decided the forward o2 Sensor needed to be replaced. I got it replaced and the O2 Register set in less than 5 miles. I could get my truck registered now. Several months later the O2 register will not set again. The Catalyst never did even after spending $600 on a new catalytic converter. I'm still mad as hell about that. Smog issues are not fun, not many know what they are doing and just start replacing parts which add up very fast.
Outstanding info...thank you! I just happened to have an on-going oxygen sensor issue.
I love your descriptions the way you explane every thing my noggin (witch now is a mush melon from all the shots to said noggin in 53 yrs) I may get my 98 ram running finally. thanks man appreciate you.
Bro you make the most informative and accurate car repair videos on the tube.
well i dont know how good it is to test ground a wire that receives a positive voltage signal . always make sure one finds the signal wire with a ohm meter before trying to find the grounds or the power wire . the signal wire is very sensitive and should never be ground or to have any other voltage input .
Keep looking........ there's more out there
I’ve done plenty looking. This dude is the shiznit.
So how did he conclude the sensor wasn't the problem?
Bro thanks for the info, I’ve learned so much in just 1 video of yours and I got my car to pass smog test that Mercedes tried to charge me an arm and a leg to fix the issue.
Thanks man you are doing a service for society. I've never called b.s. on any of your stuff
Great history, trouble shooting, and explanation of the how and why.
Thank you for the knowledge:-)
Very professional experience! You taught me something I didn't know today. Thank you, sir
super informative. Love videos like this. Good instruction, thank you for sharing.
Thanks bud you’ve simplified hours of online wiring diagram searching for me. ✊
As a mechanic myself, I could not of said/shown it any better than that. Great video.
You bet!
Very good job of breaking it down for the people , I have a hard time explaining things like this to friends and customers.....great video...
OMG! - after me pleading with you to do this for 4 years, you finally got a Patreon account!
RSSS68 Camaro If you had some knowledge to offer or anything beneficial for anyone they would be glad to help with a little bit of money for you to pay your bills. This guy makes so much informative content that really saves people a lot of money, if you save 300.00 on a trip to the mechanic you would gladly give 5 or 10 dollars out of gratitude.
@RSSS68 Camaro _ I would be HAPPY to help you pay your bills - just come up with great youtube content like Ratchets & Wrenches channel or South Main Auto Channel or ChrisFix, you get the idea! - and then start a Patreon, and people like me with give you a monthly payment - PS: I own a 1967 RS/SS Camaro, numbers matching convertible, in the original color, Royal Plum!
G'day Mate, I always watch your shows on my TV however today I'm using the computer to view your video on how to test 2 02 sensors. Which is why I'm using this opportunity to comment. Fantast work, your shows are easy to follow and always like/love the little side track you take us down usually comedy-type commentary. Cheers, very much appreciated. I'm from Australia. 👍
Great vid as usual. Love that u can simplify something that can be very confusing.
Awesome videos!!! Thanks for sharing the knowledge. I was able to fix my 1997 Accord’s sensor problem. It’s running like new!! Have a great holiday season!!
Educational videos. I am learning the operations of cars. Thank you! 👏🏿
His patience and calm demeanor is awesome
YOU ARE A GREAT GUY WITH FULL OF KNOWLEDGE AND LOVE YOUR PROFEESION AND ALSO AT SAME TIME LIKE PEOPLE TO LEARN FROM YOU I LOVE YOUR VIDEOS AND HAVE LEARN A LOT THANKS FOR EDUCATING US
I can believe how easily you explain things that could take days to understand!!
Great job brother
Who needs Scotty Kilman or Chris fix !!!!!
Great video Thanks 😊
That's because ChrisFix is for non mechanical issues mostly, and when it is about real mechanics it's about peripheral hardware mostly.
Scotty Kilmer is for N00Bs and Normies, lol… necessary because those have negative knowledge so… it's all myths and stereotypes
Rebecca Campbell interesting BECCA 🤔
WOWER MAN...that was a perfect comprehensive learn for the DIY GUY.
FANTASTICO
Thank you, nice to see you!
Very thorough and detailed I thought it was very good..
Hey R.A.W. great video thanks for showing how oxygen sensor works.
I am glad that I viewed this video so I know where to look for the oxygen sensor and I know that you should check out the wiring going to the junction box first before checking the sensors to make sure that the wiring is fine too.
Thank you for all that you do and keep up the great work and stay positive as you are
I like your videos because they are more informative & value
Big gratings from KSA
Dude, you make such great use of that testing light and multi-meter. I love the way you seem to be able to troubleshoot any electrical problem. You’re very impressive. I don’t have an immediate need for any of this knowledge, but I love watching a wiz at work so I enjoy your videos. You’re expertise is inspiring and you have a real knack for explaining these concepts so they are understandable even to a layman. Keep up the great work.

Sir, I commend your calm and expert instructions. You remind me of my Auto Tech 1 teacher in college, Mr. Garza.
Good watch made things simple
I am a diagnostic vehicle tech and loved your simplicity
Great job explaining about the oxygen sensor..I need to replace the one in my car- 2010 Ford Explorer 6 cylinder..
Nice video dude. Im currently working on why my car feels fast, smooth and quiet one day and lazy, sluggish and grunty another day. It drove me mad. I think my b1 s2 heater element retired early and not allowing ecu to enter closed loop sometimes. I reset the adaptions and feels alot better but goes back to lazy mode again later on.
Thanks, i like the way you work. Go my friend.
This video really helped me. Thank you very much!
Great video. Great Job. I'd vote for you.
What a useful video. My o2 sensor is acting up on my 2001 Olds Intrigue. I wanted to know wth is up and your video is greatly informative.
If this guy is like me, he'll be running this video back and forth a few times. Great explanation. Probably better than the manual. Thanks
Bad ass!! Keep on making awesome videos
Brilliant video thanks for showing us 🇬🇧👍🍻
Great video! Thank you for the breakdown!
YEAH , A BREAK DANCE WOULD HAVE BEEN NICE TOO.
Thanks for all your video
Learned tons of good info 👍👍
Paul had a good question and you got a good idea for a video. We all win!
Great Video. Thanks
Great vids, as always
Dude you have forgot about more things dealing with the engine than I have ever known and I call myself pretty good. Keep doing what you do. If you treat the Presidency like your vehicle diagnostic hell I mean heck (keeping it PG) we will be a step above later I expect a check in the mail.
I love the video keep up the good work man
Great video, thank you.
Good vid always good info.
Best term to use on DC systems is common not ground.
Also when you test for restistence across the signal wire and common, the voltage applied from your meter could damage the o2 sensor. Output voltage on o2 sensors are very small. This is what I learned from watching other vids. Not from my own experience, so I don't know how true that is or not.
Fez all grown up. Love it
Brilliant video
Hi I'm your new subscriber from Indian,you explain everything well thanks for your effort👍I'm looking forward to air fuel mixture tips from u.
I'd vote for you if u run for President
Awesome work
Great information .
Good job. Keep it up.
Love the multimeter !
Great Video
Thank you!!
Useful info thanks
Hi. When decelerating, my fuel system is in open loop, but once the speed fall anywhere between 20 to 10 mph, for a second I get OL has not satisfied yet conditions to go to CL, then immediately goes into CL using all oxy sensors, while still decelerating down from 20 to a stop. What would that indicate and does need to be done? No codes, no lights.
PS: you’re one of the most knowledgeable mechanics and the videos show it all.
thank you for your help
Awesome video
Hey buddy great video I've been a mechanic most of my life but I've always been intimidated by the electronical
A great help
I like the squeezy sensor at the end 🤣🤣🤣
