The best auto repair channel on UA-cam and definitely the most entertaining! A real pleasure to watch this one,I don't even know where the hour has gone...
By far the best automotive repair channel on the tube I second that. I love that the details are not so edited so that you get all the vital learning moments in there. Good job!
It is. Who else would be subscribed to the first Baptist church of Avoca. Lol. Did you have to replace the cat yet? Damn I wish I had Eric around. Is it still on the road?
Next time you see Eric tell him we named our chevy small block 350 5.7L 2500 Sierra "America". I'm in Las Vegas. Every time we start it we say 'merica. Lol. Don't have the red brake caliper covers yet though. Lol. Chevy small block, America baby. Lol
Two of the most entertaining guys to watch....you both have a passion for learning and sharing your knowledge with others and that's a wonderful combination. Thank you both.
Thanks for taking the time to do these videos - I noticed you started with daylight and ended in the dark. It takes special people who enjoy teaching the gen. public. I am watching this a second time because It is difficult for me to follow all the acronyms that are used. It's been over 20 years since I turned wrenches on cars & all of these instruments you use are amazing to me. Thanks again.
This has to be the best channel on UA-cam . Eric O did what a father does . I really enjoyed you taking time to let the young man teach me . That is one super smart newbie . Damn good hour I spent
You guys together... haha. The back and forth really helps explain things. Eric if you see this comment try to get other nerdy diagnosticians on with you. Two people questioning each other like that pushes the subject and gets it across. Thanks again for the footage. Grade A stuff man!
It's very nice to watch an other video with both Eric and Ivan! It seems, that when you get together, some chemistry happens! I hope you'll be doing more projects in the nearby future together! Keep up the good work.
Really cool seeing two guys, passionate about their profession, just having fun. I always love the banter, Eric! You seemed genuinely shaken when forced to choose between the brakeclean and the torch :D The horror!
Dude... bought a Dakota, had CEL on, BOTH O2s bad... light turned off, but, many issues still continued, namely stuttering, hesitating, weird "pops"/ backfires while decelerating/ downhill... Come to find out: FOUR of the eight bolts which connect the exhaust to the intake manifold WERE LOOSE!!!!! I was dumbfounded. Car has 25% jump in horsepower, at least... So yeah, INTAKE!!! (I'm Praying the other issue you stated that I will Not Name has not occurred as well :/ :( !!!!
Mesa, AZ May 22, 2019 Just had the same issue on a 98 Dakota with P0171 code with short term fuel trim pegged out at 32 percent positive. I went ahead and smoked it as a precaution and fastened a hanging ground strap to start. Had a feeling it wasn't going to fix it. Ran out of time for the day as I had other cars to finish. Customer had already replaced the fuel pump spark plugs cap and rotor and wires. Glad you guys made this video.I was ready to call it a O2 sensor as I saw the voltage dropped to steady 0 on the scan data. Needed more diagnostic time to confirm and here I am at night thinking about fixing his truck.
Great video. First time thru so that at times I wasn't always clear about cat voltage and fuel trims especially when in open loop. I am still trying to master this, but I have learned from you and Ivan to work thru the scientific method instead of throwing parts at a problem. It was apparent you both worked thru the night to make for us this video...again thank you
I thank and applaud you for your youtube videos. Today I serviced my 2000 Dodge Dakota (45rfe) transmission with your help. Unlike in your video my crossmember was very easy to remove and replace. So, just to keep it interesting I decided to drop my hammer on my face while taping razor blades/paint scraper to free the pan. I had to wipe the blood out of my eye three times before I realized it wasn't tranny fluid. Please keep wasting your time making videos that help and entertain people like me. Cause if you can do it, so can I.
I just found a 2000 Dodge Dakota for $3,000.00 w/ 207,000 miles. I expect to be in it quite a bit and I found your Wonderful DIY channel. Wow... What a find. I live in the Show-me state and this channel certainly foots the bill!!! will be talking to you soon Eric.. I am sure. Thanks Bro.
Well Eric, I think from now every video with the two of you in it has to have a proper headline: 'The twisted Camshafts are back!' *Insider* Just very enjoyable and educating at the same time, keep it up! And btw... I read this article...haters gonna hate, this is all I have to say. After bringing in my Civic for a rear brake job to an actual Honda Dealer and finding out later that they put in the pads the wrong way, I decided to do stuff like this on my own. If there wasn't this stupid 'getting a stamp for a service'-book mentality here in Germany to get a decent resale value, I would do all the stuff myself as long as I have the equipment. There is so much dishonesty and rip-off with repair placesgoing on, it is really hard to find a good shop you wanna stay with...mine is 250km away from where I live, but at least they know their job and don't try to rip me off...(and respect that I know something about car repair as well...)
Markus Krause i thought that happened to my santa fe. i had gotten that cam same camshaft code but after changing the oil the code dissapeared and never came back.
Awesome guys fantastic info . I think you should try the other Scotty Kilmer fix for a P0420 when the dodge comes back. Ok you get a 5 gallon bucket of hot water or 20 litres and 1 cup of Sunlight dish detergent and let it soak in it over night - rinse out and let dry :). I completely(changed to partially agree ) agree with the garage trade journal about UA-cam and auto repair videos. On the other hand I completely agree with the unsavoury reputation the auto repair industry is known for. Are all UA-cam auto repair channels reliable sources of info I say absolutely not and I would also say the same about professional independent and OEM shops. I doubt the article focused on his industries shortcomings , just the competition UA-cam. Having hundreds of thousands of subscribers is not always a sign of reliability so a bit of common sense and basic knowledge of the field leads the masses to "SOUTH MAIN AUTO" and many other fine channels like Ivan's channel that are reliable and fun to watch 👍
+Steve Rob I found the article online at the link below. Go to the August issue and then page 18-19. www.undercardigest.com/members1/online/udmembers.php
anti0918 Thanks for the link. Well I must say I do agree with many of his assertions in regards to UA-cams affect on the general public and getting their vehicle fixed. Where I part ways with the author is his condescending attitude towards the motives of UA-cam creators in general. It was quite insulting for all the hard work , expense and time that it takes to produce a video. All the channels I follow do not resemble what the article states. Well it just goes to show just because an article is in a trade magazine doesn't mean its accurate, reliable or ethical. I think the author owes an apology to honorable people like Eric and many others that enjoy sharing their talents with us. Thanks anti0918 I appreciate it.
+anti0918 The author of the article makes one big false assumption. He assumes people who refer to youtube are going to a shop to have a repair done after watching a video. UM, NO not always. People turn to youtube as a teaching-learning tool to perform a procedure or skill set on their own. Some of us "colleage" educated individuals are not as smart as we should be and refer to a video source for education. We have to determine how accurate said videos are before taking this info as genuine.
And for us non-mechanical customers we soak up every little information we can get that helps explain why our cars are at risk or we need to pay more than we expected. We go through so many videos and articles that take the time to explain what a routine fix is vs. an expensive repair. After all this hunting for facts and trusting our sources is what makes us subscribe to channels like SMA and Ivan's. So youtube videos are a life line for the general public once you learn who to trust. I have to confess Kilmer's videos where the very first ones I watched and allowed me to do further searching for other channels.
It's always nice to take some time and try different things. I think it's the best way to learn. I have used the battery to O2 sensor method for years. I guess my body has the correct resistance....LoL I have seen multiple sensors fail on a Chrysler before. It seems the original ones are poor quality and are timed to take a crap around the same time. Sometimes coolant entering the exhaust is a factor as well.
Hey I enjoyed your video. Great useful examples of testing the o2 sensors. That is a lot of useful info, but I tell ya you guys lost me when you guys were explaining about bias voltage. I know different manufactures do things a little different, and Chrysler seems to me to be the odd ball one. I thought that chrysler applied a 5 volt reference to the signal wire just so the computer can detect if the sensor is open or grounded for DTC purposes. If the signal wire is 4.5 volts or more computer assumes open sensor and if the voltage is dead zero ( there is a small threshhold usually ex .10v signal wont set code but anything below will) computer assumes sensor is shorted to ground or open. I thought that voltage was just so the computer can set a dtc code for monitoring purposes. Also I have seen some o2 sensors not the zirconia type (those type make there own voltage based on the presence of internal and external oxygen difference) but the titania type o2 sensor the computer has to send out a voltage for it to work (this type of o2 sensor does not make its own voltage) This sensor has to have a voltage sent from the computer because this type of sensor works by changing its resistance based on exhaust oxygen only. Usually 1 volt is sent out from the computer and as the o2 changes inside the exhaust the sensor changes resistance based on oxygen which varies the voltage output on signal wire. This type of sensor sends out the same signal range as the zirconia type, so they both read the same on a scan tool 0-1v. It just does it in a different way. Those are just the basic type o2 sensors not talking about any wide band type. That is just my understanding of the voltages involved with basic o2 sensor types, but not sure if that is the same thing you guys were talking about, but Chrysler is weird to me and I am not sure if I am thinking the correct way about the voltage you guys are talking about. Anyway thanks for the great video, another thumbs up from me. I am glad to have come across your channel. I have been watching a lot of your videos and I am learning. You have forever changed test light terminology for me. From here on out i am calling it scope on a rope. Good stuff. Have a good day.
About 1/2 into your car repair show Really like the way you two interact Found. Myself smiling too The content is good, always like the learning aspect as Well.
Thank you for the video Eric! I actually liked the cameraman and lack of tripod in this video. I also liked seeing you work under a car without the lift. It's interesting to see just how much a difference a lift makes both for the work and to the guy using it. As for that magazine, don't worry. They know they are an outdated format and youtubers like you are pushing them out of business. That's why they are ranting on you guys. That guy who wrote the article will soon be out of a job and since he hasn't adapted with the times he will remain jobless. Meanwhile, you will just carry on as usual and hopefully having a great time. Finally, i would use a potentiometer to alter the resistance on that O2 sensor override. This way you can set a base resistance with a resistor and then turn the potentiometer to set it lean/rich or anywhere in between as you please. Quite easy thing to make in your shop and could come in handy for situations like these. As for why the upstream sensor started working right with dual resistors in parallel. These sensors have an internal resistance and when that resistance goes up for whatever reason, adding input voltage to the already existing voltage brings the voltages back into a usable range.
Enjoy watching the both of you fellas working on car issues. You should continue to do many more or at the very least several on and off together shows... I like them or the 2 of you at this...
I'm going say the cat issue took out both O2 sensors due to running rich all the time. I'm glad I live in central Cali and dont got deal with the rust issues you have to deal with. Anyways thanks for vlog Eric.
Wow, two bad sensors, who would have thought. Great vid and testing. I put a Kenne Bell supercharger on a Mustang and it went full rich trying to correct the lean condition. Gassed me out of the garage. Found 3 vacuum leaks letting air in after the MAF. Fixed those by using carburator cleaner to find each one. So I was expecting a vacuum leak issue. Great job guys.
Awesome video! Very informative. You guys are very knowledgeable, with new tricks all the time. I love this channel!! Thank you South Main Auto!! You rock!!
That was pretty interesting. When I bought my '07 Mitsubishi Galant ES with the 2.4 I just went ahead and changed all 4 of my o2 sensors and I noticed the engine ran a bit smoother. I like to change all 4 so that everything is balanced. Not sure about the electrical properties of different makes, if it really matters. But that's just the way I like to do things. I also changed out all 4 coils as well and I don't go cheap or super expensive. Do my homework online as well as asking people who I trust who worked on cars a bit to try and get the best part for my money. I go OEM as much as possible. Thanks for sharing.
This is 2015. I've just watched part one of Ivan on a road trip 2022. I've just one question does Ivan have a Picture of Dorian Gray in his attic because I swear he hasn't aged a day in 7 years!!! I really enjoyed the collaborative video and it's great to see the two experts at work together. Buying out Radio Shack was ingenious. Way to go Ivan. Don't know when I'll need it, but it will come in handy one day. Fantastic video, I learned a lot. Just great to see you bounce off each other.
If I had to guess, I would say that it's the bias voltage that is preventing your body from pulling it very far. On those without bias voltage, it would be much easier. With the bias voltage, the voltage that passes through your body resistance has to manage to overcome the bias.
Great video guys, good info there, I personally like jacking up the radiator cap and driving a new one underneath it. problem solved in minutes (no tools needed) I have the most barren shop in town just radiator caps LOL. thanks for your time.
Nice long 1 hour video! Thank you for another long night stint (It got quite dark in the background :D ) but as always, some of us here do really appreciate it. As for that magazine guy, well he may just have stumbled across Scotty Kilmer... You should invite him to the shop where Acetylene and brake clean are on the daily menu of doing what everyone says is impossible! Keep up the great work Eric! And get Ivan to stop by once more, somehow he seems to time his presence for those odd and bizarre problems you encounter.
+South Main Auto Repair I would disagree with that... A dual failure on the O2 sensor side is rare enough that I would call it odd :P Still, great entertainment... How long did you guys keep at it?
Well that actually diagnosis I made just looking at code reader data in the parking lot (that is why I had 2 02's on hand). The testing and messing and such takes a bit over an hour or so. We don't see each other that much so there is a lot of story swapping and talking off camera so that is why the back ground changed so much...
I had a P0420 code on my 2000 4Runner. Tried the over-the-counter Cat cleaners with no help. I took the Cat down, and checked the substrate, then flushed it with degreaser and brake clean. back flowed with water and blew her dry. I started using Shell gasoline and the code never returned. The exhaust smells different, but I am happy not spending a $1000 for a new OEM CAT!!
+South Main Auto Repair At least on Toyota vehicles, the replacement CAT should be OEM, because I had a 2001 Corolla with P0420 code, and I replaced the CAT with aftermarket, only to see the code return. The O2 sensors and PCM are very particular. Hard lesson to learn!!
I know this is now an old video so not sure you'll see this, but two things; I think the upstream O2 had roughly 30k ohm internal resistance to ground, when Ivan connected those resistors in a pull up of roughly the same amount, it balanced out allowing the sensor output to drive up and down so was 'working' with the assistance of the pullup. The 2nd thing is I bought a 300ZX a little while back, both upstream sensors on that were bad, one stuck rich and one slightly lean so both banks on the V6 were doing different things... As for which failed first on that truck, I'd say the combination of dead cat and rich running killed the rear O2 as they really don't like raw petrol and was getting coated in it when cold...
Wonderful video on diagnosing the O2 sensors. I have a 97 Jeep Grand Cherokee with the 318 and the upstream one went on it as well. Great Job. Keep to going man.👍👍👍
FYI, when you change that fuel filter you are supposed to click it into the cap not insert it in the housing. Good job not overtightening the cap, as a mechanic I appreciate that. Then you need to pump the primer minimum 120 times, then turn over the engine, when it starts let it run for 10 minutes before shutdown. And as for the starter issue, the truck is equipped with an overheat protection, so it allows you to crank for 30 seconds, then it won't let you crank again until the starter cools down usually 3 minutes. This is normal don't worry about it.
not sure but the second resistor test was on a parallel ckt. good to see you guys workin together. you guys are funny. hey if you want it done faster ask mrs. o. to do it.
Just another entertaining video...well done and thanks for your time. I'm sure you've used this technique but I'll put it out there anyways. Touch the bottom of the O2 sensor/top of the boss with a candle, after squirted with oxy/acetylene, works really well... Downside is the shop will smell like a church although I like the smell.
good video, ordered me an upstream. not just youtubers, makes a difference when you're an actual mechanic n know what you're talkin about, appreciate the
Interesting how downstream o2 is unplugged and it's still running super-rich pegged out on the fuel trims and seems like upstream isn't functioning at all 🤔 is the upstream also bad or is there a separate problem @18:40 @SouthMainAutoRepairLLC
New sub here. Love the videos. Love the learning. I wish I could stay as upbeat as you guys do during your videos. When I'm done working on my car...I am wiped! Oh btw, safety glasses.
He was talking about broken manifold bolts on a 6.0 Chevy... coincidence lol I just had a Silverado in, changed the manifolds, three broke on one side and two on the other. it was the first time I ever used a MIG to weld a nut to the remainder of the bolt for extraction... worked pretty good, got 4/5 that way... ended up drilling and helicoiling one... wasn't as bad as I thought it was gonna be, time consuming though, but at least there was plenty of room to work.
Ivan does have good procedures for diagnostic work by wanting to find all problems before changing a single part, BUT, in a situation like this I would be with Eric and change the obviously shorted sensor before continuing diagnosis. In times like this I personally repair the problems one at a time if I have 100% certainty about a part being faulty. In this case, replace the sensor that is 100% proven to be internally shorted, which will very likely make finding the next problem much easier. That's because you are getting accurate data from a NOW good sensor, instead of trying to work around the faulty sensor. Where as if you leave the faulty sensor in while trying to find the second problem, it very well may give you false readings or data by interference because of shared circuitry in the wiring or how the ECM reads / interprets the signal, and the data your scan tool is displaying is from the ECM. So if the ECM is reading it wrong, you could be looking at skewed data which will screw up your entire diag.
I'm ❤ it. Working on a 2000 Dakota RT that's been sitting no run for 10yrs fuel and pump replaced now messing with O2 sensors. Bank 2sensor 1 stays in closed loop replaced both banks sensor 1. Having a good time. Customer? Lol
Thanks for the video guys ! I’m having the same trouble just replaced down stream and my fuel trim is still high going to try the upstream tomorrow wish me luck just subscribed ! Love the videos
This is a really cool video. I'm 21 and over the last year I've been getting more and more interested in automotive repair and have even considered pursuing it as a career. After watching this though - I am amazed how much computer knowledge is needed to repair a car - even one as old as 1998. I guess I'm curious what your perspective on this is - with the emergence of autonomous "self-driving" cars in the coming decade, will car repair ever become so complicated that only dealers with the right diagnostic tools and specific knowledge will be able to work on them? Will current mechanics have to go back to school to learn more about these systems and how to repair them when they fail? It seems like back in the 60s and 70s, any Joe Schmo with basic tools could diagnose and work on his/her own car. Now these highly advanced electronics have made DIY auto repair a bit of a thing of the past, unless you happen to have the right skill set and tools. I imagine this emergence of technology will follow a Moore's Law pattern - cars will become exponentially more complicated and more electronics might make car repair extremely difficult without the right tools and an advanced understanding of computer repair. How do you, as a mechanic, adapt to the rapidly changing conditions of technology? For example, how would you know how to repair a faulty adaptive cruise control system? Or hell - what about a Prius or a Tesla? Sorry for the long winded question haha. It's just a little discouraging since I am really interested in the mechanics of cars but I'm also pretty bad with computers. Just wanted to get your perspective on it. :D
You two guys make a great team Eric. You two should think about making some kind of car tech show. As for the clown downing you professionals on UA-cam here hes just a jealous hater so don't pay any mind to him. You people are so valuable to us backyard mechanics so please keep up the good work and thank you for sharing your knowledge with us.
Thanks for staying late for this video! Don't worry what some lame article says. Your channel rocks. oh and where can we pick up a South Main Auto t shirt?
Fantastic- evap leak , I hope you called Ivan and let him know there's a part 2 :) seems Ivan lives in a place called PA and some sort of park, well I asked around and the only place in NY with a PA is Park Avenue - I guess he's just around the corner from your place.
the totall resistance changed due to the sensor upstream heating up in parralel whit the 22 k resistor. (upstream sensor is also flooded whit fuel and dirty< thats why it started reacting by getting hot by leaner exhaust gasses< cleaning it up a bit.) . )
I'm open to all advice on here. So far this video helped allot with understanding what I see on my scanner. But I need a little help understanding what the fuel trim and o2s reading mean. My 1997 dodge dakota with the same motor has a STFT (%) 2.3-20.3 at idle and a LTFT (%) 5.4 steady at idle. My MAP reads 9.4 and my O2s(v) fluctuates between .220-.860. But when I bring the RPM up to 2000 my STFT goes to -2.3 - 5.4 and my LTFT drops to 1.5 steady. My MAP goes to 7.8 and my O2s stay the same. Any advice would be greatly appreciated by anyone. And yes I know it's a dodge....
My understanding is that if you have a high short term fuel trim at idle, that drops at load, it is likely a vacuum leak. Hope this is useful and correct.
Same problem with most 97-99 Cherokee 4.0. They ran terrible when cold but fine after warm up. After replacing both 02 sensors at the same time problem was solved. The was a TSB from Jeep how to correct the problem.
i would guess one o2 failed and the other one picked up the slack, and the owner kept driving with check engine light on, and some time later the other o2 sensor failed and at that point it started running bad using tons of gas and driver decided it was time to get it fixed. i dont see both failing at the same time?
It’s awesome to see good tech’s get together and share different experiences to others.Thanks for showing techniques with us viewers.
You two feed off each other and besides enjoying the diagnostics, it's fun to watch you two work together.
2 of the best known ( or unknown ) auto diagnostic minds. A pleasure to watch.
The best auto repair channel on UA-cam and definitely the most entertaining! A real pleasure to watch this one,I don't even know where the hour has gone...
+Nick Nicu Thanks :)
I have ran my transmission shop for 35 years and guys like you have made us a better trans shop thanks for the great info.
By far the best automotive repair channel on the tube I second that. I love that the details are not so edited so that you get all the vital learning moments in there. Good job!
The old Dakota is still working great. Body work is all done too.
Is that your Dakota?
It is. Who else would be subscribed to the first Baptist church of Avoca. Lol. Did you have to replace the cat yet? Damn I wish I had Eric around. Is it still on the road?
Next time you see Eric tell him we named our chevy small block 350 5.7L 2500 Sierra "America". I'm in Las Vegas. Every time we start it we say 'merica. Lol. Don't have the red brake caliper covers yet though. Lol. Chevy small block, America baby. Lol
That's terrific. It's been 3 years. Is it still in great condition?
Two of the most entertaining guys to watch....you both have a passion for learning and sharing your knowledge with others and that's a wonderful combination. Thank you both.
+Jared Mance YW Thanks for watching

It seems, that when you get together, some chemistry happens! I hope you'll be doing more projects in the nearby future together! Keep up the good work.
+Fernand Geene Van Me to Ivan is a great friend.
Really cool seeing two guys, passionate about their profession, just having fun. I always love the banter, Eric!
You seemed genuinely shaken when forced to choose between the brakeclean and the torch :D The horror!
+Koffi Banan I have nightmares about having to make a decision like that lol
Anytime I've seen two sensors crap the bed at the same time, there was coolant involved. Check the head gaskets and intake gaskets.

Good point.
Dude... bought a Dakota, had CEL on, BOTH O2s bad... light turned off, but, many issues still continued, namely stuttering, hesitating, weird "pops"/ backfires while decelerating/ downhill... Come to find out: FOUR of the eight bolts which connect the exhaust to the intake manifold WERE LOOSE!!!!! I was dumbfounded. Car has 25% jump in horsepower, at least... So yeah, INTAKE!!! (I'm Praying the other issue you stated that I will Not Name has not occurred as well :/ :( !!!!
These videos with you and Ivan tackling complex diagnostics are the best.
Mesa, AZ May 22, 2019
Just had the same issue on a 98 Dakota with P0171 code with short term fuel trim pegged out at 32 percent positive. I went ahead and smoked it as a precaution and fastened a hanging ground strap to start. Had a feeling it wasn't going to fix it. Ran out of time for the day as I had other cars to finish. Customer had already replaced the fuel pump spark plugs cap and rotor and wires.

Some quality videos you got here Eric, I really appreciate the detail and effort you go through to film these repairs.
A real good primer on the the workings of O2 sensor.Loved the different concepts and the humor.
This video could be an entire class on O2 sensor testing. Thanks for spending the time to make it.
The Dynamic Duo are back!
I thank and applaud you for your youtube videos. Today I serviced my 2000 Dodge Dakota (45rfe) transmission with your help. Unlike in your video my crossmember was very easy to remove and replace. So, just to keep it interesting I decided to drop my hammer on my face while taping razor blades/paint scraper to free the pan. I had to wipe the blood out of my eye three times before I realized it wasn't tranny fluid.
Please keep wasting your time making videos that help and entertain people like me. Cause if you can do it, so can I.

this is my ultimate - PHAD & SMA - I'm in heaven. I have enjoyed this since posted. I keep coming back. Ivan & "O" - can't get any better
Late night mechanics!! Good work both of you. Great video. Keep up the outstanding work its a joy to watch.
Well Eric, I think from now every video with the two of you in it has to have a proper headline: 'The twisted Camshafts are back!' *Insider*
Just very enjoyable and educating at the same time, keep it up!

www.undercardigest.com/members1/online/udmembers.php
anti0918 Thanks for the link. Well I must say I do agree with many of his assertions in regards to UA-cams affect on the general public and getting their vehicle fixed. Where I part ways with the author is his condescending attitude towards the motives of UA-cam creators in general. It was quite insulting for all the hard work , expense and time that it takes to produce a video. All the channels I follow do not resemble what the article states. Well it just goes to show just because an article is in a trade magazine doesn't mean its accurate, reliable or ethical. I think the author owes an apology to honorable people like Eric and many others that enjoy sharing their talents with us. Thanks anti0918 I appreciate it.
+anti0918 The author of the article makes one big false assumption. He assumes people who refer to youtube are going to a shop to have a repair done after watching a video. UM, NO not always. People turn to youtube as a teaching-learning tool to perform a procedure or skill set on their own. Some of us "colleage" educated individuals are not as smart as we should be and refer to a video source for education. We have to determine how accurate said videos are before taking this info as genuine.
+anti0918 Some folks just refuse to share their knowledge for the benefit of others. The author sounds like that type.
And for us non-mechanical customers we soak up every little information we can get that helps explain why our cars are at risk or we need to pay more than we expected. We go through so many videos and articles that take the time to explain what a routine fix is vs. an expensive repair. After all this hunting for facts and trusting our sources is what makes us subscribe to channels like SMA and Ivan's.
So youtube videos are a life line for the general public once you learn who to trust.
I have to confess Kilmer's videos where the very first ones I watched and allowed me to do further searching for other channels.
Great video!!
The correct terminology for swapping parts is "Random replacement of indiscriminate parts".
+Rick Anderson haha thanks
Indescriminate as opposed to imaginary - such as muffler bearings and blinker fluid.
I really like your troubleshooting process - it's deliberate and thorough.
you guys are simply awesome in the way you go about diagnosing stuff..u cant put enough videos for us to watch..All the best to you !
It's always nice to take some time and try different things. I think it's the best way to learn. I have used the battery to O2 sensor method for years. I guess my body has the correct resistance....LoL I have seen multiple sensors fail on a Chrysler before. It seems the original ones are poor quality and are timed to take a crap around the same time. Sometimes coolant entering the exhaust is a factor as well.
Once again... you have given me a greater appreciation for what I don't know. Where's the book????
Hey I enjoyed your video. Great useful examples of testing the o2 sensors. That is a lot of useful info, but I tell ya you guys lost me when you guys were explaining about bias voltage. I know different manufactures do things a little different, and Chrysler seems to me to be the odd ball one. I thought that chrysler applied a 5 volt reference to the signal wire just so the computer can detect if the sensor is open or grounded for DTC purposes. If the signal wire is 4.5 volts or more computer assumes open sensor and if the voltage is dead zero ( there is a small threshhold usually ex .10v signal wont set code but anything below will) computer assumes sensor is shorted to ground or open. I thought that voltage was just so the computer can set a dtc code for monitoring purposes.
Also I have seen some o2 sensors not the zirconia type (those type make there own voltage based on the presence of internal and external oxygen difference) but the titania type o2 sensor the computer has to send out a voltage for it to work (this type of o2 sensor does not make its own voltage) This sensor has to have a voltage sent from the computer because this type of sensor works by changing its resistance based on exhaust oxygen only. Usually 1 volt is sent out from the computer and as the o2 changes inside the exhaust the sensor changes resistance based on oxygen which varies the voltage output on signal wire. This type of sensor sends out the same signal range as the zirconia type, so they both read the same on a scan tool 0-1v. It just does it in a different way. Those are just the basic type o2 sensors not talking about any wide band type. That is just my understanding of the voltages involved with basic o2 sensor types, but not sure if that is the same thing you guys were talking about, but Chrysler is weird to me and I am not sure if I am thinking the correct way about the voltage you guys are talking about. Anyway thanks for the great video, another thumbs up from me. I am glad to have come across your channel. I have been watching a lot of your videos and I am learning. You have forever changed test light terminology for me. From here on out i am calling it scope on a rope. Good stuff. Have a good day.
Wow I learned a lot here thanks guys. Highly enjoyable video. Loved the trick with the resistors getting the O2 to fluctuate, that was wild.
+DJDevon3 Thanks DJ
About 1/2 into your car repair show
Really like the way you two interact
Found. Myself smiling too
The content is good, always like the learning aspect as Well.
I have a special technique I use, when I see a Dodge/Chrysler vehicle I run the other way. It has saved me a lot of time and headaches :)
+JD A Nahh, just nuts and bolts
Thank you for the video Eric!
I actually liked the cameraman and lack of tripod in this video. I also liked seeing you work under a car without the lift. It's interesting to see just how much a difference a lift makes both for the work and to the guy using it.
As for that magazine, don't worry. They know they are an outdated format and youtubers like you are pushing them out of business. That's why they are ranting on you guys.
That guy who wrote the article will soon be out of a job and since he hasn't adapted with the times he will remain jobless.
Meanwhile, you will just carry on as usual and hopefully having a great time.
Finally, i would use a potentiometer to alter the resistance on that O2 sensor override. This way you can set a base resistance with a resistor and then turn the potentiometer to set it lean/rich or anywhere in between as you please.
Quite easy thing to make in your shop and could come in handy for situations like these.
As for why the upstream sensor started working right with dual resistors in parallel. These sensors have an internal resistance and when that resistance goes up for whatever reason, adding input voltage to the already existing voltage brings the voltages back into a usable range.
These two fellows together could fix the space shuttle. HIRE the boy Eric!
Enjoy watching the both of you fellas working on car issues. You should continue to do many more or at the very least several on and off together shows... I like them or the 2 of you at this...
I'm going say the cat issue took out both O2 sensors due to running rich all the time. I'm glad I live in central Cali and dont got deal with the rust issues you have to deal with. Anyways thanks for vlog Eric.
Excellent video. Laughs and ALWAYS something to learn despite what the critics say. I found myself laughing out loud a few times. Thanks gentlemen.
+ManicMechanic007 Well glad a few found it useful :)
WOW! Two master blasters working on a problem!! Well done!! Good tech session!! Love the scope data.
Ivan is also a sharp tech good to have a good pal like him
sure is he is a smart guy
Wow, two bad sensors, who would have thought. Great vid and testing. I put a Kenne Bell supercharger on a Mustang and it went full rich trying to correct the lean condition. Gassed me out of the garage. Found 3 vacuum leaks letting air in after the MAF. Fixed those by using carburator cleaner to find each one. So I was expecting a vacuum leak issue. Great job guys.
+raykrv6a Oh got ya. Leaks after the MAF can cause problems for sure.
Outstanding, hope you both do more of these. Dream team.
Great job guys and both of you look to have a lot of fun working together. Wish I could have been there...
+stuzman52 Doors unlocked Terry come on over!
Awesome video! Very informative. You guys are very knowledgeable, with new tricks all the time. I love this channel!! Thank you South Main Auto!! You rock!!
I like how you test things on this channel all parts are innocent until proven guilty no matter how guilty they appear at the beginning
Love how Ivan rags on him for the parts replacement labor when his own diagnostics took like 8 hours
That was pretty interesting. When I bought my '07 Mitsubishi Galant ES with the 2.4 I just went ahead and changed all 4 of my o2 sensors and I noticed the engine ran a bit smoother. I like to change all 4 so that everything is balanced. Not sure about the electrical properties of different makes, if it really matters. But that's just the way I like to do things. I also changed out all 4 coils as well and I don't go cheap or super expensive. Do my homework online as well as asking people who I trust who worked on cars a bit to try and get the best part for my money. I go OEM as much as possible. Thanks for sharing.
Wow. A one-hour diagnosis video? I'm going to have to come back with a bowl of popcorn.
This is 2015. I've just watched part one of Ivan on a road trip 2022. I've just one question does Ivan have a Picture of Dorian Gray in his attic because I swear he hasn't aged a day in 7 years!!! I really enjoyed the collaborative video and it's great to see the two experts at work together. Buying out Radio Shack was ingenious. Way to go Ivan. Don't know when I'll need it, but it will come in handy one day. Fantastic video, I learned a lot. Just great to see you bounce off each other.
If I had to guess, I would say that it's the bias voltage that is preventing your body from pulling it very far. On those without bias voltage, it would be much easier. With the bias voltage, the voltage that passes through your body resistance has to manage to overcome the bias.
This is like Click and Clack (the tappet brothers) for the next generation. Fantastic content.
Great video guys, good info there, I personally like jacking up the radiator cap and driving a new one underneath it. problem solved in minutes (no tools needed) I have the most barren shop in town just radiator caps LOL. thanks for your time.
Nice long 1 hour video! Thank you for another long night stint (It got quite dark in the background :D ) but as always, some of us here do really appreciate it.
As for that magazine guy, well he may just have stumbled across Scotty Kilmer... You should invite him to the shop where Acetylene and brake clean are on the daily menu of doing what everyone says is impossible!
Keep up the great work Eric!
And get Ivan to stop by once more, somehow he seems to time his presence for those odd and bizarre problems you encounter.
+CMDR Sweeper Yeah this one wasn't so odd but it is nice to have him as a friend so we can bounce stuff back and forth.
+South Main Auto Repair I would disagree with that... A dual failure on the O2 sensor side is rare enough that I would call it odd :P
Still, great entertainment... How long did you guys keep at it?
Well that actually diagnosis I made just looking at code reader data in the parking lot (that is why I had 2 02's on hand). The testing and messing and such takes a bit over an hour or so. We don't see each other that much so there is a lot of story swapping and talking off camera so that is why the back ground changed so much...
I had a P0420 code on my 2000 4Runner. Tried the over-the-counter Cat cleaners with no help. I took the Cat down, and checked the substrate, then flushed it with degreaser and brake clean. back flowed with water and blew her dry. I started using Shell gasoline and the code never returned. The exhaust smells different, but I am happy not spending a $1000 for a new OEM CAT!!
+jake ounce Believe it or not I ran this through a drive cycle this morning..NO P0420!?
+South Main Auto Repair At least on Toyota vehicles, the replacement CAT should be OEM, because I had a 2001 Corolla with P0420 code, and I replaced the CAT with aftermarket, only to see the code return. The O2 sensors and PCM are very particular. Hard lesson to learn!!
I'm still shocked No PO420. Most of those throw one if you go over a bump to hard. Those Dakotas make me nuts.
I know this is now an old video so not sure you'll see this, but two things; I think the upstream O2 had roughly 30k ohm internal resistance to ground, when Ivan connected those resistors in a pull up of roughly the same amount, it balanced out allowing the sensor output to drive up and down so was 'working' with the assistance of the pullup. The 2nd thing is I bought a 300ZX a little while back, both upstream sensors on that were bad, one stuck rich and one slightly lean so both banks on the V6 were doing different things...
As for which failed first on that truck, I'd say the combination of dead cat and rich running killed the rear O2 as they really don't like raw petrol and was getting coated in it when cold...
Wonderful video on diagnosing the O2 sensors. I have a 97 Jeep Grand Cherokee with the 318 and the upstream one went on it as well. Great Job. Keep to going man.👍👍👍
FYI, when you change that fuel filter you are supposed to click it into the cap not insert it in the housing. Good job not overtightening the cap, as a mechanic I appreciate that. Then you need to pump the primer minimum 120 times, then turn over the engine, when it starts let it run for 10 minutes before shutdown. And as for the starter issue, the truck is equipped with an overheat protection, so it allows you to crank for 30 seconds, then it won't let you crank again until the starter cools down usually 3 minutes. This is normal don't worry about it.
Great collaboration !
Finally, landed on a video with these two masters in one video.
not sure but the second resistor test was on a parallel ckt. good to see you guys workin together. you guys are funny. hey if you want it done faster ask mrs. o. to do it.
Curious Ivan vs. practical on the clock Eric, clashing minds for the best diagnosis!
No 1 video I have watched from SMA , so much learning and very entertaining Thank you Gentlemen
Just another entertaining video...well done and thanks for your time.
I'm sure you've used this technique but I'll put it out there anyways.
Touch the bottom of the O2 sensor/top of the boss with a candle, after squirted with oxy/acetylene, works really well... Downside is the shop will smell like a church although I like the smell.
My father had a 98 Dodge Dakota 2 door sport. I miss it wish I can get it back. I like very that good old truck. First truck ever drove.
good video, ordered me an upstream. not just youtubers, makes a difference when you're an actual mechanic n know what you're talkin about, appreciate the
You two are having way too much fun!
Interesting how downstream o2 is unplugged and it's still running super-rich pegged out on the fuel trims and seems like upstream isn't functioning at all 🤔 is the upstream also bad or is there a separate problem @18:40 @SouthMainAutoRepairLLC
New sub here. Love the videos. Love the learning. I wish I could stay as upbeat as you guys do during your videos. When I'm done working on my car...I am wiped! Oh btw, safety glasses.
*+South Main Auto* perfect answer on the flame wrench vs. brake kleen lol
Christmas 2022!🎄
These trucks are still good looking. I have a white extended cab 2003 Dakota.
Nice job and I wash my engine occasionally too never had any problems
Outstanding work as usual! Eric O keeps everyone firing on cylinders.& very educational too !
loved the video! eric and ivan make a great team!
He was talking about broken manifold bolts on a 6.0 Chevy... coincidence lol I just had a Silverado in, changed the manifolds, three broke on one side and two on the other. it was the first time I ever used a MIG to weld a nut to the remainder of the bolt for extraction... worked pretty good, got 4/5 that way... ended up drilling and helicoiling one... wasn't as bad as I thought it was gonna be, time consuming though, but at least there was plenty of room to work.
what a video man. one of your best. thanks guys
Ivan does have good procedures for diagnostic work by wanting to find all problems before changing a single part, BUT, in a situation like this I would be with Eric and change the obviously shorted sensor before continuing diagnosis. In times like this I personally repair the problems one at a time if I have 100% certainty about a part being faulty. In this case, replace the sensor that is 100% proven to be internally shorted, which will very likely make finding the next problem much easier. That's because you are getting accurate data from a NOW good sensor, instead of trying to work around the faulty sensor. Where as if you leave the faulty sensor in while trying to find the second problem, it very well may give you false readings or data by interference because of shared circuitry in the wiring or how the ECM reads / interprets the signal, and the data your scan tool is displaying is from the ECM. So if the ECM is reading it wrong, you could be looking at skewed data which will screw up your entire diag.
I'm ❤ it. Working on a 2000 Dakota RT that's been sitting no run for 10yrs fuel and pump replaced now messing with O2 sensors. Bank 2sensor 1 stays in closed loop replaced both banks sensor 1. Having a good time. Customer? Lol
Thanks for the video guys ! I’m having the same trouble just replaced down stream and my fuel trim is still high going to try the upstream tomorrow wish me luck just subscribed ! Love the videos
Update ! All is fixed and running good thanks again guys !
This is a really cool video. I'm 21 and over the last year I've been getting more and more interested in automotive repair and have even considered pursuing it as a career. After watching this though - I am amazed how much computer knowledge is needed to repair a car - even one as old as 1998. I guess I'm curious what your perspective on this is - with the emergence of autonomous "self-driving" cars in the coming decade, will car repair ever become so complicated that only dealers with the right diagnostic tools and specific knowledge will be able to work on them? Will current mechanics have to go back to school to learn more about these systems and how to repair them when they fail?
It seems like back in the 60s and 70s, any Joe Schmo with basic tools could diagnose and work on his/her own car. Now these highly advanced electronics have made DIY auto repair a bit of a thing of the past, unless you happen to have the right skill set and tools. I imagine this emergence of technology will follow a Moore's Law pattern - cars will become exponentially more complicated and more electronics might make car repair extremely difficult without the right tools and an advanced understanding of computer repair. How do you, as a mechanic, adapt to the rapidly changing conditions of technology? For example, how would you know how to repair a faulty adaptive cruise control system? Or hell - what about a Prius or a Tesla?
Sorry for the long winded question haha. It's just a little discouraging since I am really interested in the mechanics of cars but I'm also pretty bad with computers. Just wanted to get your perspective on it. :D
Enjoyed the video. Was fun to watch and really educational. Thank you for making the videos you do.
+OnTheBrink Thanks for watching :)
28:05 KN Filter joke? i didn't understand the last part. probably watching the sand go by..
Great special guest!
Shoot I ended up using my map gas and plumbing pipe wrench and it still took some time to get it out on my truck. It was orginal 29 yrs old ox sensor.
You two guys make a great team Eric. You two should think about making some kind of car tech show. As for the clown downing you professionals on UA-cam here hes just a jealous hater so don't pay any mind to him. You people are so valuable to us backyard mechanics so please keep up the good work and thank you for sharing your knowledge with us.
Thanks for staying late for this video! Don't worry what some lame article says. Your channel rocks. oh and where can we pick up a South Main Auto t shirt?
+chewy1147 I am hoping to have them for sale soon. I will post it when I do.
Believe it or not I ran this through a drive cycle this morning..NO P0420!? Must be the PCM is not real sensitive on this matter?
Well the customer will be happy happy happy....
But it did throw a "large EVAP leak" Better than a converter though!
Fantastic- evap leak , I hope you called Ivan and let him know there's a part 2 :) seems Ivan lives in a place called PA and some sort of park, well I asked around and the only place in NY with a PA is Park Avenue - I guess he's just around the corner from your place.
No actually he is several hours from my place. State College PA. Wait a minute now... you pulling out some Canadian humor on me...
+South Main Auto Repair Did you monitor the O2 signals? Maybe some of that carbon in the cat cleared off when you "gave it the beans" lol
haha. I had to get those same damn resistors. and got em from radio shack. Mainly used on air bag circuits.
Eric, Ivan, good video with good info and a fix. Keep the vids going.
The German torque wrench gag made me laugh. Cracking double act, just love it.
Pretty neat seeing Ivan helping ya and close to home, Only 30 mins away from my home where his shop thats pretty sweet.
+Devon Morder Look him up if you need some stuff.
the totall resistance changed due to the sensor upstream heating up in parralel whit the 22 k resistor. (upstream sensor is also flooded whit fuel and dirty< thats why it started reacting by getting hot by leaner exhaust gasses< cleaning it up a bit.)
.
)
I'm open to all advice on here. So far this video helped allot with understanding what I see on my scanner. But I need a little help understanding what the fuel trim and o2s reading mean. My 1997 dodge dakota with the same motor has a STFT (%) 2.3-20.3 at idle and a LTFT (%) 5.4 steady at idle. My MAP reads 9.4 and my O2s(v) fluctuates between .220-.860.
But when I bring the RPM up to 2000 my STFT goes to -2.3 - 5.4 and my LTFT drops to 1.5 steady. My MAP goes to 7.8 and my O2s stay the same.
Any advice would be greatly appreciated by anyone. And yes I know it's a dodge....
My understanding is that if you have a high short term fuel trim at idle, that drops at load, it is likely a vacuum leak. Hope this is useful and correct.
Enjoyed the forcing high ,low,well done Eric.
I'm looking at otc test-lights on amazon. which one should I choose?
On the Hyundai Elantra both o2 sensors always fail with the code 2196 I've seen them all the time
Same problem with most 97-99 Cherokee 4.0. They ran terrible when cold but fine after warm up. After replacing both 02 sensors at the same time problem was solved. The was a TSB from Jeep how to correct the problem.
i would guess one o2 failed and the other one picked up the slack, and the owner kept driving with check engine light on, and some time later the other o2 sensor failed and at that point it started running bad using tons of gas and driver decided it was time to get it fixed. i dont see both failing at the same time?
