I'm a heavy equipment mechanic, diesel and hydraulics (concrete boom pumps). I dable with automotive and watch every video that you post. I'm going to be a master tech just from watching your videos.
Know many mechanics and Techs watch you. Thank you for not forgetting that many of us are DIY'ers and that you keep explaining things in a more elementary fashion.
Awesome video as usual. I also want to say that the genuine love and respect you have for Mrs. O is absolutely incredible to see. You are not just an incredible diagnostician and mechanic, but a true gentleman. Nothing but respect Mr. O
Actually, for sailors the saying is "Take 1 watch with you or 3 watches. If you take 2, you do not know which one is correct." It is better to trust something false than get trapped in indecision in the case of 1 watch. In the case of 3 watches, it is probable that 2 will agree to be closer to the truth.
"There's a few things in this world, folks, that don't lie. Five-year-olds, and yoga pants. There's a couple things that do lie. Scan tools, service data, and politicians." - Eric O.
Im a diy guy so in cases where I have two of something and one is working I check power and ground are good, if they both are I swap them. If the problem follows the part it has to be the part. O2 sensors, coils, plugs, injectors, and so on. It's not the quickest method in many cases and it's not the most sophisticated but it gives good info quickly. I like to see your more indepth approach though.
My Saturday morning coffee.... listening to Eric describe the the nuances of swap-tronics and yoga pants. Great video...as usual! And a special thanks, to Mrs. O for her impeccable camera skills, and diagnostic insight.
Another great video. I am not a mechanic/auto electrician but have watched enough of your videos to follow and anticipate what checks you are going to do so your methodology and explanations are consistent and clear. Good job again. ps I still think Mrs O should put a cookbook together, if she can run the office and cook a hot lunch for you then everyone can........... That sounds familiar?:,-)
One thing I have noticed alot with watching your videos is that American cars have terrible cable management, and you get all sorts of rub spots. When I did the rear brakes on my M5, the cable management for the wear sensor was an absolute work of art in comparison, weather proof boxes over any under-car cable plugs, rubber mounting grommets all the way along cables, and cable tie down points every few cm
Took me a second, but once I got the "sometimes they lie to ya folks" I was about to fall out of my chair from laughing so hard!!-) Thanks for all the knowledge and humor that y'all bring us Mrs. And Mr. Eric O. God bless you both.
You're a great mechanic man I appreciate your videos. I was very impressed how respectable you were towards your wife, but more importantly her demeanor and how willing she was to help you out. Very impressive keep these videos going bud!
Eric is exactly right ....as yesterday at the shop I'm putting in a new fuel pump and fuel filter for a 2007 ford 500 .....started great for about a minute then the engine lost power and stalled out with check engine light ....3 codes showed ...all referring to the fuel pump and fuel level sensor being the culprit .....long story short ...after all the tests replaced the fuel pump and runs perfectly now !
Never had good luck with aftermarket O2 sensors. Our Ford E250's with the 5.4 would eat O2 sensors like crazy. Ford parts needed to know if it was bank 1 or bank 2 where Car Quest or NAPA said they were the same part no. The aftermarket O'2 sensors would get 'lazy' after 2 or 3 months. Nice camera work Mrs. O!
Test lights... Just the other day I was at the scrap yard for the purpose of scoping out some project steel for an upcoming hydraulic press tooling build. I scored a nice truck center link (tie rod bar/pipe) for the project. But, while in Rome and all that, I cut out numerous incandescent marker lights and tail lights to round out my simulated-load testing equipment. Once home the lights were extracted from their wiring looms, the ends stripped, and the raw copper wire solder tinned. Since I'm a DIY guy (setup speed not a priority), the tinned ends allow for alligator clips to configure probe pins and/or series/parallel configuration versatility. I also used an amp clamp to determine the draw of each light harness. The amp draw amount was Sharpied onto each bulb socket. So, I'm pretty much set with incandescent load stand-ins!
I retired my trailer, soldering all the connections, and using heat shrink on those connectors. About three months later, I started having wiring failures. After bypassing too many broken wires, I decided to retire it again. I determined my original solder I used was acid core, not Rosen core. The acid ate right thru my connections.
Yep, acid core solder will make quick work of electrical connections. For what it's worth, I've been soldering electrical repairs and ad-ons for decades. I also keep the vehicles for decades. I have yet to have one of my dozens upon dozens of solder joins fail.
The bracket over the battery is missing. Thanks for the info, I only have 78k on my 12. I will be putting something under the sensor wire to help prevent rubbing wire. Top notch instructor.
I have to remember that about never lying. Your commentary is as good as your mechanical skills. Top Notch all the way. You hit the lottery when Mrs O said I do to you. Keep them coming! They are a valuable source of knowledge!
Thanks for this video. I would have to say that is the most complete O2 sensor test video I have seen. Specially showing how to use your small test light to drive the sensor high and low. Also pumping the brake pedal versus unplugging a vacuum line is genius too.
Kind of wish this video was out a few hours ago, I only just finished working on a car where the TCM was complaining of an accelerator fault the reading would suddenly lock to a specific number (about 20%) which turned out to be the ECM going into a "limp" mode of sorts because of a faulty fuel rail sensor connector..... I have to admit, I spent too long looking at accelerator related stuff because that's the number that stopped responding. Either way, problem fixed. Thanks for all your videos, I have learnt more into the trade than you can imagine when it comes to electrical fault finding mindsets due to your explanations and showing the thought processes.
I really shouldn't drink coffee while watching you, Eric: "There are two things that don't lie: five year olds and yoga pants..". Always good to watch your process. Thanks!
Wish I had SMA just round the corner, I admire your work ethics Mr O. Doesn't exist here in Sweden, finding a good mechanic here is rare, at least in my experience ! I enjoy most of your video's, I learn a lot ! So thank you Mr O !
better you than me dealing with the electronics in the newer vehicles. after watching you and scotty kilmer the last couple of years i'm not touching any of this stuff. you can have it. i'll pay for a shop to deal with it. good job none the less. and great you included Mrs O.wouldnt be good without seeing her
For those that watch this that are not technicians, at 12:20 when he says the resistance is 12.2 which means it's roughly 1 amp. It's not just pulling a number out of thin air. Techs use ohms law, or the pie chart when dealing with electricity to verify the right specifications. V(voltage) = i(current) x R(resistance). So if R = 12.4 and V = 12.4 then V12.4 ÷ R12.4= i 1 amp.
On my 98 S10, 4.3, ordered three new O2 sensors from one of our favorite interweb sites. All three failed. Went to my favorite auto parts store, which coincidentally I fondly call Mr "O", and bought three (for twice the net order price) and they all worked perfectly. Same (supposed) manufacturer, same part number. No clue why. All I can say was, I was warned about ordering those, but I did it anyways. Won't be doing that again. I did make a youtube video of that adventure.
Well ill ramble off a few words . I am sure everyone and anyone who watch's your videos should not ever have anything bad to comment about because with your positive attitude even when your aggravated as you mentioned, you still keep calm and respectful to Mrs.O and all of us viewers. My wife of 29 years would tell me to get over it and take a hick on being camera lady lol. Thank you Mrs.O also for her respect and help for any vids she is camera lady. Need to make her an award for sure and hang it in the office for her. Now im off too tackle my 01 jimmy bank 1 sensor 2, the pos, but totally confident after this vid . You keep burning rubber bro the skids your laying down are impeccable.
I have the same problem, intermittently 2002 chevy v6 pickup . I put in new sensors,because I was there...I think one is bad...Thanks for solving the problem! I also have clutch problems, so I am replacing everything, and rear main engine seal.I have fun working on my vehicles...NO RUST here..come retire here you and Mrs. O. Thank you for all you do Peter chambers in AZ.
GM doesn't like aftermarket sensors. If it's not genuine AC Delco some of them take forever or never run the monitors. Even Delphi sensors the heater monitor will often never complete
Heater circuit draws ~1 amp at 3% duty cycle, but you measured 12 ohms across the heater terminals. One side of the heater is shorted to ground inside the sensor!
Excellent video as usual. 👍 One thing I thought of here on this particular situation is that the "new" sensor was purchased and installed by the owner (or other shop) and there's no way of knowing it had ever been dropped or otherwise mishandled. The whole issue of bad "new" sensors reminds me of a caution label/sticker I once read on a O2 sensor box i.e. "A dropped sensor is a bad sensor!" Word to the wise I've never forgotten.
Well done eric as usual. Way to stick to the facts. I am a 25 year shop owner and a 36 year tech and that's the first time i have heard of triagnostics. 😅
Great Video Mr. O! Honestly, you've forgotten more about mechanics than I know, I enjoy watching your videos and I've learned a lot! This video had it all - humour - "Two things in the world that don't lie" - awesome - wrote that down and Mrs. O making an appearance. You two are an inspiration!
Hey Eric, in Canada. We have found on gm's. if you don't change. All the O2 sensors. The old ones. For some reason. Will kill the new O2 sensor. In a couple of months. I can't tell you why this happens. But alot of shops. Wont change just the one. Because we have been burned. In the past. Just like in your video. The guy changed the one. And the other 3 killed it. Soon after replacing it. Thats with new OEM ac delco, sensors. Love watching your videos. Keep up the good work brother.
Great video Dr O as usual. I know people will argue, but “NEW OEM” have less failure rate than “NEW Aftermarket” IMO. I know OEM commands a bigger $ tag, but there are some things you shouldn’t go aftermarket on IMO. Awesome video, thanks for the detail troubleshooting process and explanation. 👍👍
@@Troy_Built it's only gonna get worse, supply chain issues mean everyone has had to use substitute materials at one point, doubt that tha the proper testing is done everytime this happens.
Similar experience for me.. Just a guy with some tools and the wife's Rav4 with a bad O2 sensor. I replaced it with one from Amazon. While it fit and the plug was the same, after a day, money light on again for same O2. Bit the bullet and went to Toyota and bought their OEM for like double the price... But, it fixed the issue and is still working fine after several years now.. I was able to return the Amazon one for a refund, so no loss there, except for the time, but learned a good lesson right there...
There are no coincidences…. So there I am minding my own biz driving down the road coming home from a food store run and WHAM! the money light comes on my ‘13 Chevy with the big 5.3. Get home, put the groceries away get the scanner out, O2 Bank 2 Sensor 1 code. Ok go inside flop down on the couch, and there’s Eric O troubleshooting an O2 sensor problem on my engine series! Yeah baby! If only it worked that way with lotto tickets. Ordered OEM AC Delco Bank 2 upstream & downstream from Rock Auto not a sponsor, and now we wait…… 😎
Don’t feel bad Mrs. O. I don’t know how he reads that scanner either, although it’s a great machine, you have to understand what you’re looking at though? I wish I knew how to use a bi-directional scan tool. Great knowledge to have. Nice job, as usual Eric👍
Great video. Just to sum up, there were a total of two (2) bad O2 sensors; the original plus the new one from the previous mechanic. Thanks in advance.
Nice to see Mrs. O is doing well. The diagnostics don't lie and so it's true, the new part is junk and the new new part is working. You wrung out the circuit and it pointed to the sensor. Good one Mr. O.
I used to do PDIs at the Cadillac dealer I worked at many years ago. On occasion during the inspection of a new car I would find components that didn't work on cars that had less than 10 miles on the odometer. So faulty new parts applies to OE automotive manufacturers as well as aftermarket.
Great driveability troubleshoot. About halfway through I started thinking "swap the O2s and see what it looks like," but it was satisfying to see you chase it all the way to the end. Make sure you charge enough for your diagnostic time.
It's your attention to detail that always impresses me Eric. I may not always understand the nuances but I have tried to copy your methodical and systematic approach and it has helped me immensely. I'm just a shade tree DIYer but your methods and advice are spot on for me as well as the professional. I sometimes still fire the parts cannon but much less often and I am gradually getting a better grasp on actually diagnosing problems. I just did a battery draw on my daughters 97 Chevy 2500 (after re-watching every one of your videos on the subject) and you were in my head, coaching the whole time. You are making a huge difference in the DIY community and with the state of our country at the moment, that impact is desperately needed. Never doubt that. Thank you!
👏🏻👏🏻 for Mrs. O on her camera operating videography. Love the comment on the 5 year old and yoga pants, so true. Keep up the great work and information sharing
Just purchased my Autel scanner and am excited to be able to look at data such as this better then my old scanner to better diagnosis issues for my customer
What a great morning chillin in bed as it’s cold n rainy n what do I see… a SMA vid! Sweeeet haha. Well done as usual as u teach us ur wisdom n funny ass jokes. Thanks for making a mundane Saturday morning into a great one
Yo Eric. I'd swear you were an Electrician in another life. Your approach is totally sound, and Electrician like. Emissions are taking the simplicity out of Auto repair. Nicely Done! Part Made in China?
I went through this with a 2009 changed the o2 twice with denso. Both would always stick rich. Switched with the there bank. Which had a acdelco. Problem went to the other bank. So went and got a acdelco o2. Problem is gone. Was told the newer gens are picky about aftermarket sensors
From the GM tech training center in Hinsdale IL, all the way back in 1996: "The idea of OBD2 strategy is to always save the cat." While it didn't work so well at 1st, you can plainly see that they have the software now! It can really send someone down the diagnostic rabbit hole if you're not well versed! KISS method still works, and Eric suspected o2 foul play fairly early on, but wasn't convinced. Still, what he did, and does, is anyways a thorough diagnostic approach with simple and conclusive tests!
If I suspect an O2 sensor I always try to replace it with an OEM. Some cars, especially foreign, are sensitive to the brand use. Nothing wrong with Denso or Bosch, both are typically very good.
"There are a few things that do lie: scan tools, service data, and politicians". Cannot agree with you more😅, especially on the last one. Thank you for the great video!
Great in depth diagnosis of issue and resolution. Might have been more in depth than needed, but great explanations and info for future issues. Thank you.

@@samuelmcbride it's absolutely true.
It be nice if the PCM had a "mode" PID that would report whether it was using a default strategy.
Yes it would. It could easily report if it were in fail safe. Great point.
It does, in OBD2 generic the data isn’t manufactured as it is in oem.

@@Troy_Built it's only gonna get worse, supply chain issues mean everyone has had to use substitute materials at one point, doubt that tha the proper testing is done everytime this happens.
I've had genuine OEM fail just as rediculously fast as dorman, gates, airtex,dayco, etc. I think it's all low quality nowadays
Just ran through one of that issue bad parts denso same part number , you the man , Ms O thanks for your support
Similar experience for me.. Just a guy with some tools and the wife's Rav4 with a bad O2 sensor. I replaced it with one from Amazon. While it fit and the plug was the same, after a day, money light on again for same O2.
Bit the bullet and went to Toyota and bought their OEM for like double the price... But, it fixed the issue and is still working fine after several years now.. I was able to return the Amazon one for a refund, so no loss there, except for the time, but learned a good lesson right there...
You finally figured out this is what all of the dealers do swap the parts skip all the diagnostics much quicker and cheaper for the dealer.
Skilled Labour isn't cheap Cheap labour isn't skilled Love it
There are no coincidences…. So there I am minding my own biz driving down the road coming home from a food store run and WHAM! the money light comes on my ‘13 Chevy with the big 5.3. Get home, put the groceries away get the scanner out, O2 Bank 2 Sensor 1 code. Ok go inside flop down on the couch, and there’s Eric O troubleshooting an O2 sensor problem on my engine series! Yeah baby! If only it worked that way with lotto tickets. Ordered OEM AC Delco Bank 2 upstream & downstream from Rock Auto not a sponsor, and now we wait…… 😎
Don’t feel bad Mrs. O. I don’t know how he reads that scanner either, although it’s a great machine, you have to understand what you’re looking at though? I wish I knew how to use a bi-directional scan tool. Great knowledge to have. Nice job, as usual Eric👍
Never seen the pump the brakes to lean it out.. gold bro
Mrs. O: "I have no idea what's goin' on." ...me neither but Mr. O is some sort of frickin' genius, AND HILARIOUS! SMA is the highlight of my day.
Mrs O, Great camera work in sharp focus an lite correctly. I did not understand anything else.
Mrs O is the brains and beauty of the operation.
I’ll trust the yoga pants before 5YO’s….just sayin. 👍🏻
Great video. Just to sum up, there were a total of two (2) bad O2 sensors; the original plus the new one from the previous mechanic. Thanks in advance.
Great video and diag. Mrs. O has added a new skill.
You introduced a can of Brakleen but none of the "ta-da" sound, I miss that nostalgia.
Nice to see Mrs. O is doing well.
The diagnostics don't lie and so it's true, the new part is junk and the new new part is working.
You wrung out the circuit and it pointed to the sensor.
Good one Mr. O.
Your diagnostic skills continue to impress me
You stay doing some electrical. Thats how I found you years ago. Keep up the good work!
Love the sense of humour you've got. Always a few chuckles in amongst the diagnostic gems
I used to do PDIs at the Cadillac dealer I worked at many years ago. On occasion during the inspection of a new car I would find components that didn't work on cars that had less than 10 miles on the odometer. So faulty new parts applies to OE automotive manufacturers as well as aftermarket.
Great driveability troubleshoot. About halfway through I started thinking "swap the O2s and see what it looks like," but it was satisfying to see you chase it all the way to the end. Make sure you charge enough for your diagnostic time.
This is one of the best info on the tube about 02 response and diagnosing 02s great video man. Wish you were in my area!!!
I love ❤ 😍 that Chevrolet Thunder video clip you showed us of it going down the road at the front of your shop! 🤣🤣🤣🤣🤣
Let's say it together "Just because it is new does not mean it works!" Thanks for another great video.
15:52 That ACTION gesture was priceless
Alway make sure to look at the signs 0:09 and Thank all that helped, right Mrs O
As Always Great Video Mr.O
Eric O this was definitely a good teaching O2 sensor video. Thanks for sharing and you and family stay safe and well 😊🇺🇸
It's your attention to detail that always impresses me Eric. I may not always understand the nuances but I have tried to copy your methodical and systematic approach and it has helped me immensely. I'm just a shade tree DIYer but your methods and advice are spot on for me as well as the professional. I sometimes still fire the parts cannon but much less often and I am gradually getting a better grasp on actually diagnosing problems. I just did a battery draw on my daughters 97 Chevy 2500 (after re-watching every one of your videos on the subject) and you were in my head, coaching the whole time. You are making a huge difference in the DIY community and with the state of our country at the moment, that impact is desperately needed. Never doubt that. Thank you!
Mrs. O is a winner! You are a lucky man Eric!
👏🏻👏🏻 for Mrs. O on her camera operating videography. Love the comment on the 5 year old and yoga pants, so true. Keep up the great work and information sharing
Just purchased my Autel scanner and am excited to be able to look at data such as this better then my old scanner to better diagnosis issues for my customer
Saturday morning with Mr O. Enjoy your weekend.
What a great morning chillin in bed as it’s cold n rainy n what do I see… a SMA vid! Sweeeet haha. Well done as usual as u teach us ur wisdom n funny ass jokes. Thanks for making a mundane Saturday morning into a great one
Yo Eric. I'd swear you were an Electrician in another life. Your approach is totally sound, and Electrician like.
Emissions are taking the simplicity out of Auto repair.
Nicely Done! Part Made in China?
Truer words have never been spoken at 9:53 😂
Mrs. O is a very good camera operator - very smooth shots! If only she didn't have about a thousand other things to do each day...
I went through this with a 2009 changed the o2 twice with denso. Both would always stick rich. Switched with the there bank. Which had a acdelco. Problem went to the other bank. So went and got a acdelco o2. Problem is gone. Was told the newer gens are picky about aftermarket sensors
Mr. O, you never ramble!
From the GM tech training center in Hinsdale IL, all the way back in 1996: "The idea of OBD2 strategy is to always save the cat." While it didn't work so well at 1st, you can plainly see that they have the software now! It can really send someone down the diagnostic rabbit hole if you're not well versed! KISS method still works, and Eric suspected o2 foul play fairly early on, but wasn't convinced. Still, what he did, and does, is anyways a thorough diagnostic approach with simple and conclusive tests!
I’m having the same issue new sensor but still the same code. Going to try a new one tomorrow thanks for doing all that, I was scratching my head.
If I suspect an O2 sensor I always try to replace it with an OEM. Some cars, especially foreign, are sensitive to the brand use. Nothing wrong with Denso or Bosch, both are typically very good.
I know a guy who replaced an O2 on a Porsche and it did not like Walker but was fine with NTK.
"There are a few things that do lie: scan tools, service data, and politicians". Cannot agree with you more😅, especially on the last one. Thank you for the great video!
The problem is that the grill clearly says Chevy, but the steering wheel clearly says GMC. Bad juju.
Oh crap. I've got GMC center caps on my Chevy
Mine does that. Right on the airbag. Have to wear a face shield when I drive it.
Meh, Chevy...GMC...same thing
@@stevel4035 yes junk
Mrs O excellent camera skills 👏, Mr O things that don't lie YOGA PANTS 😂🤣 that's funny,
Great in depth diagnosis of issue and resolution. Might have been more in depth than needed, but great explanations and info for future issues. Thank you.
Just as my electronics teacher said over 50 years ago...You have just found it was a leaky coupling capacitor, now replace it with a GOOD capacitor.
You want to test the O2 sensor? Press the brake, of course! I love counterintuitive tests.
Hooray, another video with the lovely Mrs O in it. Well done Eric.
you have got to be the best that i have watched so far and i watched quite a few, why have i watched so many? well simple,,,, nobody has explained it like you have, and for that my new youtube friend, I Thank You! not to mention you are Funnier then giving a dog peanut butter!
Good job
