The content we have at our fingertips is crazy. Just 10 years ago videos like this were rare. If you wanted to learn what it's like to be in the field, you had to go in the field. As someone who's just a few weeks away from starting work as a technician, these videos are invaluable. I'm starting out with a much greater knowledge base to draw on than any beginner you'd typically see, and that will be instrumental in my success early on. You, Ivan, Keith, ScannerDanner and EricTheCarGuy are a big reason I have successfully diagnosed countless problems with friends and family vehicles, as well as my own. And the knowledge I've gleaned from all these channels is only going to get more valuable when I start doing this for a living. Thank you.

[@SouthMainAuto]

Glad to help any time Dylan

[@ericeiler7016]

Thank you Eric O. I am no longer a parts changer just hoping to fix my car. Test, Test, Test and verify. 👍

[@heyitschinoable]

Same

[@SouthMainAuto]

That is right , always test first and learn how to verify first

[@wymi]

The SMA Motto: Test but Verify

[@randylooper2346]

I can feel your frustrations on getting wrong part or just waiting forever on delivery driver, time is valuable in auto industry esp when you have to make money i really appreciate your videos mr. o. I want to thank you for such educational videos and what you mean to the youtube community

[@philby49]

Ok EricO, thing is I am soon to move to BC Canada, in UK right now, I am 63 yrs old and retiring, what you have shown here is how honest and trustworthy you are, I have learned lots about North American vehicles from watching your vids, (I did 20 yrs as a mechanic here in UK when younger) if I were closer when I moved to BC I would come to you for all my vehicle needs, which made me think, your next step could be featuring customers who travel just to get you to fix their vehicle, as I think that will be pretty common soon, in fact maybe buy yourself an old Motel to put them all up, I would happily be one of those customers, either way, another great logical fix top work, Dave

[@bradnimbus4836]

Gotta love that friendly Prospector Pete "Welcome Back"! Thanks for the upload Eric. SMA makes my coffee taste better in the morning

[@SouthMainAuto]

Thanks Brad!

[@stewart4295]

Thanks Eric, Americans are very willing to share their knowledge on KZbin, and thats a good thing, regards, Stewart, Australia.

[@SouthMainAuto]

Better out than in I always say

[@xerxes456]

I remember the early 80s when they scared you to never use a test light for many years I thought that was the real deal. Great as always Eric.

[@e13c7r0nic]

I love waking up to a new SMA video. I feel like a kid waking up to Saturday morning cartoons :)

[@Paul1958R]

Thank you Eric for another great video. I have the Actron CP9580 which I bought in 2010. It is good basic DIY code scanner but only accesses limited PIDs but I am happy with it. God bless you Eric O. Paul

[@jonathanfreedom1st]

Just Subscribed, As a mechanic myself.... I think it's good ethics and Transparency to show customers what you are about. Cheers from Toledo

[@kmcca08]

You really should have a million subs. I'm a mechanic also and I love your videos. Keep them comin man..👍🏻

[@wyattoneable]

Your kicking videos out like Vanessa and the kids left on vacation without you. This was a simple test but as usual, your commentary and tips added a lot of value. I'll be hanging around for more information on that Actron. My local mechanic uses one...in fact, I think it's the only scanner he has.

[@InsideOfMyOwnMind]

wyattoneable yep. Kick in em out like a welfare mom.

[@SouthMainAuto]

Haha, yeah it is a good scanner but should not be the only tool of a professional shop. It has to many limitations. It is not my opinion it is just a fact. If you run a pro shop with this as your only tool, your days are numbered...

[@wyattoneable]

Oh yeah, our local guy is a parts changer.

[@clarencek3658]

I swear I'm gonna be the best DIY mechanic thanks to Eric o lol

[@lucyp.3119]

I don't need stinkin notifications I'm already addicted to this show.

[@obadiah7771]

Great vid! Your humor makes the vids entertaining. Keep up the good work!

[@worsttintentions]

It's nice to have the shop doors back open again!

[@leedress2187]

I haven't had the chance to work with the actron scan tool, but the Autel MD802 is a GREAT DYI scan tool. it gives you make specific codes, ABS/SRS Transmission, etc.. totally worth the 200 bucks it goes for.

[@AP9311]

Eric O, great vid!! I've been on the market for new DIY scan tool, boom. you were doing it. Holy smokes, you been reading my mind, lol!! I missed couple videos due to lack of notifications. but this one did notify on my phone! yay. I finally caught up! I'll wait for your reviews first before I'll buy. Thanks, later, my friend!

[@Bekim8310]

Awesome video Eric! I am one of those viewers thats waiting for you to put out a video on the best diy scanners. I know you mentioned it a while back. For me it has to be the Autel. Give us a nice in depth review! Thanks man!

[@SouthMainAuto]

Coming soon

[@petar443]

Great video man. I've learned a lot from you. Keep up the good work!

[@andrewadams7439]

one word...Wow mechanical genius South main auto and eric o are my idol love the knowledge keep it coming i watch your channel for hours i love it and tell every body bout it at my shop now at lunch we all watch you lol haha!!!!

[@SouthMainAuto]

haha idol!?! Your nuts!

[@mr.nobody9630]

That was EASY, Eric O. A + Rating

[@chopaholics]

Im so hooked on your videos cause the way you diagnose vehicles you inspire me to diy my own cars just wish you where here in Georgia so you can film my car too god bless

[@mahlerob]

Thanks so much for this Sienna video. I was beginning to wonder if anyone in your neck of the woods drove siennas. I have a 2004 Sienna with over 220,00 miles and it's been a great car.I just changed the bank 1 sensor 1 AFR which was quit a bit harder to get to, especially lying on cardboard on my gravel driveway. And guess what , I use the exact same Actron scanner. Do you have many siennas in your area? I really love your channel. It's the best.

[@FunktapusGaming4Lyf]

That beautiful sound of a tool tumbling through the engine bay and hitting the ground below...;)

[@MyMickey50]

I got the 5 dollar OBDII from Amazon - bluetooth to my Android phone... saved me mucho grande deniro!

[@Sandbag1300]

At 8:13, "snug it up to factory specs, of course....Click". It does not get better than that!

[@Starcrunch72]

a la Elderly Iron.com

[@SouthMainAuto]

as long as you hear the click you know it is right!

[@MyMickey50]

You need to do a Scotty Kilmer grunt when tightening to factory specs!

[@klystron1]

love your videos! keep up the hard work. should have a million subs.

[@omegaswarriors]

well eric i went out and bought the autel maxidas diag tool. 850 clams and it works great i get to see data in real time

[@anthonyiwuoha5089]

Thanks bro. YOU ARE GREAT Love your video.

[@jimg7423]

You saved me a bunch of cash. Thanks I can't believe the price difference between our auto repair guy and Amazon. I just know someone is making a huge amount of money for nothing

[@Chris_905]

another brilliant video , looking forward to the code reader review as im in the market to get one myself ,they seem a very usefull tool for the toolbox , thanks !

[@SouthMainAuto]

Yes they sure are

[@kuruji]

Yet another fantastic and informative show. I was hoping to see the Actron data stream on an good AFR sensor. Maybe you have that on another one of your excellent vids.

[@blessedbonesautogarage3167]

Excellent video, having same issue with my Toyota 2008 RAV4, will try it out and revert back to you. Thanks,

[@geraldsanford2411]

great video ERIC O

[@mikechiodetti6737]

Great Video. I've seen heater failures. Not often.

[@lightningsmokerXx]

Eric i am slowly dying inside until that Krown Video is posted.

[@SouthMainAuto]

Coming soon trust me!

[@richardabner9420]

Great videos as always!

[@clintonandrews1538]

Hey Eric, watching your handy-dandy magnetic LED work light, I'll bet you don't miss your trusty ole' 100W incandescent combination drop light and branding iron.

[@MadMattz76]

Thanks for the video. I have this same year Sienna, so some good info. I dread the day I would have to access anything on the rear bank on this thing....

[@SouthMainAuto]

Yeah they are a little snug back there

[@Badgertronix]

Autel is the entry level scan tool of choice according to the Staten Island master. Well that's what he sent me anyway 😎

[@JPilot2]

G'day, Mr. O! I am Sharing... A very useful tool! (Actron - CP9690) "The tool use is very straight forward and intuitive. Within 10 minutes of playing with it you have most of its function down. I used it to read a check engine light. Read P0420 which is catalyst inefficiency. I let the car warm up and then selected live diagnostics. You can see all the PID's or you can create your own custom list. I like that feature. I selected the PID's relevant that I needed to see to confirm a diagnosis. Short and long term fuel trim shows me that the engine is running rich (too much fuel in the mixture). Coolant temp is spot on. Voltage feedback from the O2 sensors showed me what I needed to see. Then I recorded a short 5 min drive, and graphed the data. Downstream O2 sensor is all over the place. Verified that the O2 sensor is working properly. P0420 in my case is a bad catalytic converter." Plus, the scanners troubleshooting is a nice feature as well. Useful for Veterans, and inexperienced wrench turners alike, It gives you a checklist so you know where to start and where you should start searching next. It certainly help to save money by not throwing parts at a vehicle. Thank you! Cheers! :-)

[@melvinjohnson7033]

Good vid as always. I have the OTC 3211 which I believe is identical to your Actron.

[@int53185]

I still use my nearly 20 year old Actron to do quick checks and resets. You can't beat their reliability.

[@heyitschinoable]

A good entry level scanner i used is the Autel AL619 check engine, airbag and abs for about 120 on Amazon

[@982414justin]

i bought the autel scanner for diy it seems to be pretty good

[@vincegagich1796]

Thx for your help. Great help

[@alexyamson]

another key for me, thanks sir Eric....

[@theoldwizard998]

I am anxious for you review ! Your old one was a CP9580. That is a CP9690. The only down side to that model is the current software only handles ABS and SRS up through 2013. It would be nice if it handled tire pressure monitors. 4 years is a long time without updating the software. Actron is now owned by Bosch and that model looks identical to the Bosch OBD 1350. I also think Mac resells the same one. Bosch also owns OTC now.

[@spelunkerd]

What an excellent review of how to do things properly and efficiently. Good diagnostics don't have to be slow, and you don't need a lot of fancy tools. Regarding the antiseize, most of the O2 sensors I've put on come with their own little packet or have it on already. Maybe it's becoming an urban myth, but I've read a few times that the wrong antiseize can mess up the O2 sensor, presumably by mucking up the sensor end in some way. Does anybody know more about how that happens? I suppose when it gets really hot, you could change the local oxygen concentration around the outside of the sensor, changing readings. Or, maybe when really hot the wrong antiseize could drip down onto the end of the sensor, covering the end that needs to sample the exhaust gas.

[@SouthMainAuto]

I think you are right in the sense that people may put on to much. I use a very small amount of copper never seize just on the threaded portion

[@haywardsautomotive6156]

Nice diagnosis & video as usual. Gotta love wrong parts to slow you down.

[@fieldsofomagh]

Can't wait for the Action review, need it right now, patience has bottomed out----- Where is my review ??? this is an emergency !Tell the customers to come back next week an there's real work to be done.

[@johnaclark1]

A friend brought me his 05 Accord 2.4L the other day that was setting the MIL intermittently. When I scanned it it was showing P0141 (B1S2 heater code) stored but not turning on the MIL at the moment. I did these same tests, expecting to see an open or real high resistance but got around 8-9 ohms on the heater which comes to only about 1.5 - 1.7 amps. I backprobed the heater wires, connected my Vantage meter, and saw a nice PWM square wave for the heater from 0-14 volts while the engine was running, so obviously PCM and wiring to the sensor check out. I thought the heaters always failed open but it seems they can go intermittent or just slightly high, too. I found a spec in my 07-10 Odyssey factory service manual (assuming they're the same) for the rear O2 heater and it gives 5.4 - 6.6 ohms. I can only assume the heater is either failing intermittently or just going high enough resistance to set the code when the engine is cold. Will find out after I put the new sensor in on Friday.

[@SouthMainAuto]

I have seen them fail intermittently for sure. Eventually it will go open

[@johnaclark1]

First time I've seen it intermittent. It's always been open when I've checked one with a heater code. Thanks for the confirmation of that! I couldn't 100% verify the bad sensor, since heater resistance can change with heat, other than ruling everything else out.

[@InsideOfMyOwnMind]

johnaclark1 Big huge major thing to point out with the repair of anything electrical, mechanical or even biological, every possible failure type can and does often present as intermittant unless of course you're talking about catastrophic failure of a given component. Anyone with experience will treat every diag process as potentiality intermittant in the way they handle things like harnesses, connectors, sensors, etc. If you were to try (and why would you) you could turn 80% of those "sure deals" into intermittant nightmares.

[@MrPhetaste]

hmmm werè geting spoiled, a smar ewer`y day.. as allways Eric great video...

[@BryanMecklenburg]

Thanks for taking the time to make this great video. The Toyota OEM part number for this sensor is 89467-08070. It will cost about $223 plus tax at your local Toyota dealer. I bought my part on Amazon from a Toyota dealer in Daytona Beach Florida for $155, no tax, no shipping. Toyota gets this part from Denso so another option if you don't want to order the part over the Internet is to go to Advance Auto Parts. They sell Denso #234-9049 for $159 plus tax.

[@haroldlm64]

Good job!

[@georgebaerreis4720]

This is by far my favorite channel on youtube. I know you have a review coming out on that actron but can you tell me if it's worth the loot? Thanks for everything you do!

[@SouthMainAuto]

IMO it is

[@capella8632]

Thank-you 👍

[@mraccord92]

first! morning routine on hold now..

[@NewLevelAuto]

Terrific job as always brother. Now don't put out a video for a few days so I can release mine 😁

[@SouthMainAuto]

OK haha I will give you a one day window.. is that enough time?

[@UtahDarkHorse]

I know this video is dirt old now, but would like to know which Actron that is. I had a 9690. it wasn't all system, but I needed it because it did OBD1. Otherwise, would have gotten the 9695. Anyway, I liked it. Have a better one now. Thanks for yet another great video!

[@garageworker]

Eric, you should take a look at the Autel MD802 or the Autel diaglink for $110. They both do live data and mode 6, would love to see what you think of them.

[@wearevergold6478]

Got the p0051 Blues? That Beefy Juicy taste! Need a little excitement? Snap into an AFR sensor! OOOHHH YEEEEAH!!!

[@aboutmyfathersbusiness8324]

Holy guacamole! I dont have all the Verus rigamarole but I do have a 8 year old Actron!

[@SouthMainAuto]

Sometimes that is all we need!

[@geosutube]

I need to find a mechanic like him over here in Orange, California.

[@emtscythe3782]

When that socket started to fall I instinctively froze and listened for the hopeful sound of metal hitting concrete!!!!!

[@shaneharrison4775]

I think we all do that lol almost every time too

[@Nope-un5lq]

I love Eric's euphemisms... lol for sure :-)

[@josephtucci3666]

Nice job Eric or the price every DIY:er should have one Looks like you are getting the hang of the Vantage pro.

[@SouthMainAuto]

Yeah it was a small learning curve from the mt2400

[@francisphillips8192]

was that torque setting one or two clicks of the elbow have to make sure you get the correct number of clicks

[@bamawild2355]

Here down south we laugh at o2 and Evap codes. Put a black sticker on the instrument cluster and keep truckin.

[@Krillekris]

You are so good at finding alternatives to cursing, love your way around it :-P I got a Autel MS906 as a DYI tool, but the MaxiDAS DS808 is cheaper and looks nice as a DYI tool.

[@SouthMainAuto]

Try to keep it rated G

[@rogerb6611]

thank you very much

[@richardcranium5839]

see how you are lol i just picked up an otc . researching them the otc bosh and actron seem to be the same. you got the one with the changeable cables.since i wont be working on german or obd1i opted for the next higher model.took a long time for the first firmware update but i can print from it and do a couple other ford things.will be really interested to see what you can do .

[@SouthMainAuto]

Yeah Bosch/OTC owns Actron

[@heyitschinoable]

Great video once again! Would testing with continuity at the A/F sensor should work the same to see if its open?

[@SouthMainAuto]

We did do a resistance test on it? Is that what you mean?

[@shahsmerdis]

Have you ever noticed the difference between denso/OEM? usually there is a good reason if OEM is 2-3x the price.

[@Mr424538]

Hey Eric the scanner you used in your video appears to be the same as the Bosch Obd1300 I use. Maybe it's just a rebrand? Either way I'd like to see what you've got in store for it. Keep up the good vids.

[@thebandmcomputer]

Great video Eric....I laughed at the beginning of the video because I don't think Mrs. O realized she was on video when she was bending over doing who knows what.

[@mib20000]

I seen that . she was mooning us

[@SouthMainAuto]

Lol yeah she was painting a coffee table

[@mfsperring]

First thing I noticed too. Had to stop video to see if it was mentioned in the comments. I knew it would be. I'm not sure I want to know what that says about us, lol. Now back to concentrating on the other content. :)

[@josemontes9050]

Eric the scanner looks new. Can you make a review of it.

[@hyenathug3056]

Hi Eric: How did you get the a/f sensor test light. Could you share the link? Thanks God Bless you and your family

[@popeb69]

any suggestions for the same code but a good o2 sensor?

[@sweetwilliam49]

What I'd like to know is why I need a heater circuit. What happened to if the heat gauge says warm cut the heater on?

[@bodgitandleggitgarage]

I think you need to calibrate your torque sensor I only heard one click don't forget about the Grant torque setting lol I've had people comment on my vids saying it is impossible to get the wrong parts from the dealer happens more than they think

[@OneAuto]

I think Toyota specify medium 'grunt' torque setting for this vehicle Leon?

[@SouthMainAuto]

I uses "uhgs" instead of grunts...

[@aussiebloke609]

Medium grunt torque spec? Sounds like Leon. Good to see ya, mate! :-)

[@bodgitandleggitgarage]

aussiebloke609 cannot beat the Grunt torque specs 😁😁😁

[@professional2.09]

Great video I would of failed on checking the signal out thanks Bank 1 and bank 2 what side is what I believe you not the internet lol

[@luischavez6391]

What bulb did you use to check heater control from ecm? Is it a regular 194 bulb?

[@CleanSC]

A Toyota repair vid? I saw it on the feed and thought... "Man, this should be short and/or boring." Right, Ivan? ;) Haha Sure enough. :D It's the same in my shop. Toyotas come in, and it's yawner oil changes and brakes and the occasional filter or sensor. When the big three show up, it's time to pull out all the fun diag toys and go gremlin hunting. Great vid, Eric. We also need the easy simple ones as some of us could use refreshers and others just don't know how to handle the more common easy stuff. I bought one of those Actron 9690's last year to keep in my truck. It's nice, tho it takes FOREVER to pull codes compared to it's taller predecessor the 9180. I only use it for scans on the road if someone needs it. The Code connect is nice, as it gives top fixes for codes. Basically Identifix for the diyer's. Just don't take it as gospel. Direction at most. I prefer the older 9180 for the quick stuff like just reading or clearing codes. That thing is lightning fast.

[@PineHollowAutoDiagnostics]

I got another Toyota vid coming up really soon...more exciting that an O2 sensor or rusty exhaust pipe haha

[@CleanSC]

Looking forward to it! As a Toyota specialist shop (poor career decision - hah!), life is pretty boring around here ;p Toyotas are 90% of my clients, yet the 10% other brands I do work on are 80% of my profits. heh.

is this code strictly for the front o2 sensor i have just replaced my front o2s but im still getting the code

If you happen to know, out of curiosity I was wondering if this sienna is a 3.3L?

[@edwardgomez1700]

Hey Eric did you make that test light used in 4:35 by any chance?? Where did you get it I want one like that, easy to probe, great video!!

[@theoldwizard998]

Bosch replacement sensors (not that I would use a Bosch O2 sensor on any Japanese car) solve the short/long cable problem by only selling ones with long cables and they include a zip tie !

[@guilopur]

Good morning...

[@dwaynerattan6749]

Hi i did similar test on 2002 Camry 1AZ-FE the light comes on when i first start the egine but turns off after 15 seconds. If i clear the code light comes on 15 seconds then off again. Is that the expected behaviour?

[@movingupautodiagnostics8645]

Oh yeah!
