Hello Paul (and Caleb)! My son got me a gift certificate from AES Wave for Christmas, so I'm going to be ordering your book! I'm excited to read it and to learn from it. God bless both of you and Caleb's new family! Merry Christmas to both of you.
@Total Confusion
That's a ridiculous comment. What happens behind this scenes, is we can't keep up with everyone. You answer one question and then they multiply. Like the scene in Bruce Almighty when he's answering emails? It is exactly like that.
But I do care, whether someone is a paid member of my website or not.
@Dave Osbun you won't be disappointed with AESwave! In fact I'd like to add to it, one, just to stick it to the wet blanket comment below, and two because I do this all the time. I'd like to offer you and SD/AES Grant to shop with them. All of my affiliate revenue earned from AES is being dumped into an account where we give back to our industry. Whatever I offer from this account AES matches dollar for dollar. Copy your message and then mine right here, and send it to support@scannerdanner.com and I'll set you up with one. Merry Christmas my friend and thank you for your support!
@Total Confusion I'm not sure why expecting to earn money with your knowledge means you don't care about people. In fact, I'd say just the opposite is true. I'm sure it's safe to say you've never visited the premium channel nor have you viewed any of the content there. It's free for 14 days...check it out for yourself and cancel it at the end of 14 days. Then see if you can come back and make the same ridiculous comment with a straight face. You cannot find better training than what is offered there for the minuscule amount he charges. A few years back I signed up for the premium with the intent on watching and canceling because I'm cheap. I'm still a premium member today. I have earned TONS more money with the knowledge I've gained than I could possibly pay Paul Danner for his premium channel in a lifetime. I'm an amateur doing repairs and diagnostics as a side job to my regular job and have fixed cars that local shops couldn't fix, all thanks to the premium channel.
Also, if you paid any attention you see that much of the proceeds he earns from certain things go straight to people in need. So, you're just wrong about Paul Danner. He expects to get paid for his knowledge but he cares and is also a very generous Christian. He's a winner in my book.
@Total Confusion you haven’t a got a clue, what he teachers in the book and premium is second to none, look what other top you tube mechanics say about him , Ivan from pine hollow auto diagnostic and Mario from super mario diagnostics and Eric from south main auto just to name a few, and so what if makes any money , I should hope he does I want to see someone getting on in life than not ,
Been a SD premium student for the last year. Best investment i have made towards growing in the auto vehicle world
I owned this car with the same engine 3.5L V6 except mine was a 2008. I owned it since it was new from the dealer. I kept taking it back for this misfire issue and they kept telling me I was crazy. Come to find out, the VCM feature (variable cylinder management) shuts off the rear bank of Cylinders in 3 cyl or 4 cyl mode. If you check all 3 rear cylinders all the spark plugs will be fouled but the front is clean. This fouling problem happens on highway driving or coasting when cylinders are deactivated to save fuel. However the intake valves still open, thus EGR pumps soot and oil into the rear bank fouling the plugs but never burning the recirculating exhaust gases. So my solution was a cheaper 2 year spark plug change and I never had a misfire for the life of ownership.
As soon as I saw this video I knew what it was because I owned this car for so long before selling it. It's not a horrible issue if you just keep up maintenence on the spark plugs. The engine never burned any oil, it was simply a problem with the VCM feature from Honda. Honda even provided a software update to help the issue. I never tried it. I'm not a mechanic so I didn't bother with it.
can also be oil fouled caused by bad oil control rings
You got it. Also, echo comes on when it comes up to temp. A mode to trick the temp reading by reading the hose temp instead so echo never comes on. 5 degree temp change read will do it.
I've lost count on how many years I have been checking out these videos...real time content....see you at training!!!!
Thank you!
RPM drop test is one of the most useful tests in my "toolbox"
I love how understanding you are of the customers costs. You’re right you need to look out for the customer in this world of expensive bills. Paul you’re such a nice guy my man.
Awesome video! Love how real and candid the Danners are!
Very common on all the honda v6s with VCM. It will continue to foul plugs on that cylinder. There was a settlement, extended warranty coverage, etc. around this issue. Great video, as always!
That car is out of even the extended warranty. Needs the VCM disabled. $129 for the VCMTuner, new plugs and it's good to go.
it just needs driven Italian tune-up style on the daily 🤣
It's not just Honda. I've run into the issue with many manufacturers that have cylinder deactivation. I think it is not only the added vacuum but also low tension rings you see going in most engine's in an effort to reduce drag. All in the name of fuel economy.
Great teaching video as always. From one grandpa to another grandpa, have a very Merry Christmas to you and your family!
Nice easy one for once. Good old swaptronics work great. Just get two spark plugs and replace number 2 and put the other in the glove box with a cheap spark plug tool for the customer. Merry Christmas to all the Danners.
Hello, Paul. Sorry to hear about your mother, praying she will be okay.
I agree with you Paul; you can change a lot plugs for the price of a rebuild! Great video and info as always! Thanks.
Hi Paul and Caleb,
Thank you again for this great video!! In my opinion it is always a good first step to swap the coil and plug to an more exessable location. Not only for easier acces but also to eliminate an failing fuel injector or enginefailure for that cilinder. For me an small step in between.
Oké boys; marry Christmas and al the best for this new year.
Cheers from the Netherlands
One of the smartest car dudes on UA-cam
Merry Christmas danner family!
I’ve seen the flashing cel as a knock event and a catastrophic failure but I’m lucky I haven’t had it on my car. A friend of ours had it on her Hyundai and the dealer replaced her motor under warranty. I’m glad you made this video as this accord has a J series engine and I have 2008 Acura tl type s it has the 3.5 but similar so if I ever have this issue I can reference this video.
Hey, enjoyed the video. That Honda needs a VCM muzzler and of course a set of plugs. It has cylinder deactivation on cyls 1,2,3, it seems that it creates a vacuum in those cylinders pulling more oil in and oil fouling the plugs... keep up the great work Paul and Caleb, I guess Danner deserves some praise as well.
The VCM on my 2008 Odyssey was a contributing factor that messed up my motor. Once I slap the reman motor in it I am going to purchase that VCM deactivation jumper harness.
You guys are an awesome team!!!!!
Love this style of realistic perspective diagnostics. All the way to the “gotta pay the grocery bill” perspective of the customer. Great job and Merry Christmas ti the Danner family.
Praying for your sweet momma too. My wife’s currently dealing with cancer so my hearts definitely more tender towards those struggling with similar issues.
Just prayed for your wife my friend. Mom is doing good! Thanks for asking. May the peace of God that surpasses all understanding be with you in this situation.
Merry Christmas and a happy new year my brother in Christ... Abuelito Paul.
Sometimes the Old School way is still the good way. You made me nervous grabbing the ignition wires/coils with the engine running. Electricity constantly searches for a path to ground and a willing conductor like the human body. Stay safe amigo
Great logical approach. Great content.
I was a gm tech for along time I did pistons almost daily for issues like this.
That thumbnail is pure gold.
A quick way to do a cranking compression test on Honda vehicles would be to select “Injectors - all” under the “Functional Tests” menu. You then have to perform a “ECM/PCM Reset” after you’re done to re enable injectors.
In a pinch, I've found that carburetor cleaner spray works great for cleaning spark plugs.
For RC test on Honda quickly, use the All Injectors Off function. Then to return to normal select the Ecm/Pcm reset
Thanks a lot team Danner and Merry Chirstmas for you and your family =)
Thanks Paul and Caleb as always for your great work. I hope you and your families have a great Christmas!
As usual, well done. Happy New Year.
Hi SD. Great video! Show us snap on truck on the rear
Good job
Minimooooooooooooooo excellent video and. I have the subscription also. Thank you master. Danner
Thank you so much!
This car simply needs VCM (ECO) disabled with a VCMTunerII. It's $129 or so and disables the cylinder deactivation. That and a set of new plugs and that car will most likely run many more miles. I run it on my own V6 Honda. 240K trouble free miles and counting.
Hey Paul. While the Snap-On truck is there, why don't you pick up a 12V lead so that you can use the Verus even if the battery dies
Have same car and problem replaced PVC valve it was stuck oper when turned. Car off over time fowled out only one plug must have seapped into intake when off to a certain intake port
I have changed the plugs and coils and still doing the same thing
I just found your video because my dad's 03 mdx is having multiple cylinder misfire. We did the drop test and cylinder 3 failed that test to where no rpm change. We changed sparked plug and coil and still having misfire. Did the drop test again after installing new olugs and coil and cylinder 3 still fails the droo test. Any suggestions where to look next? And thank you in advance. Great content. New sub 🙂👍
Check compression of that cylinder next. Tell me what you have. Then we'll look at the injector next
@@ScannerDanner Thank you. I appreciate your response. Will check those next and report back 🙂
Man it's so hard watching Honda repair videos as a Honda tech. I was screaming pull the plug from the beginning knowing the plug was going to be fouled lol
Get rid of the aftermarket stuff too
Is this Honda trying to make a low friction engine by having low ring tension against the cylinder wall?
I love diagnostics ! Good info on the fuel trims as well !
Hi Paul, and Kaleb, AND the Bearded one, great video, Nice to be working outside in December in Pa.Merry Christmas and A Happy New Year to the Danner Family!!
WoW, Love the quick diag plan, instead of taking a different approach,I've been practicing this plan since I've started learning from you SD Stay Blessed Bro❤
Special Thanks to James Danner & Caleb Danner👍
Stay Safe Guy's❤
Hey brother, I would recommend you to get the book "Engine Perfomance Diagnostics' ! I got mine 2 years ago, it has been most valuable investment ever.
@@PistonShack Great suggestion Bro👍
Totally agree with you 💯%
I got mine in Feb of 2020, had to request my uncle in State's to place the order with AESwave & ship it to me via USPS😉
Honestly it's the best investment I've ever made (it's an asset), & I can't thank SD enough for compiling all this knowledge & changing our lives, huge effort👍
It's a must have (must read) book for tech's anywhere😉
@@isalmankhan1 INDEED, BROTHER! Take Care.
The Big Picture : You Will Become The Average Of Who You Surround Yourself With! That's a conclusion I've come to @ 62 YO. If you watch Paul Danner on a regular basis your skills of diagnosis will improve dramatically. Try using these skills in areas beside auto repair. Again, thank you Paul.
Thank you my friend
Merry Christmas Mr. Paul
I love you and the way you work ...
God bless you man
I put a VCM Muzzler on my 2006 Odyssey and I love it. Installed at 163k. The issue I had was it felt like a trans mis-shift that occurred every time you came up to speed. In fact I hated to see the green econo light come on. Right after installing the Muzzler I did an oil change and discovered shiny metal in the oil. Tore the engine down and discovered front camshaft lobes were worn (163k) and 2 rod halves and 1 main half bearings were showing wear. Rear cam looked like new so did not change. Changed the cam ($300) and the bearings. Trying to figure out size/color of the bearings was a real hassle. Dealer totally worthless. So far so good. The engine always ran quiet so no change still runs great. Have not pulled plugs. Just got the Odyssey at 161k and it does not appear to use oil. So do not know history before I got it. I think the previous owner sold it because every warning light was one when I first started it. All easy fixes. TPMS/Traction was low tire pressure (nail in tire) and the check engine light was caused by a clogged screen on the VVT soldenoid. I bet the owner was not savvy and the $700 Toyota wanted for the new valve did him in. I fixed the screen for $10.
Hi, I have a 2011 accord 4 cylinder Sedan EXL model gave engine light flashing error and it was not running more than 10 mph on the road. My mechanic changed the spark plug, changed coils, changed fuel injuctors with rail. Checked the pump, running fine. Still gets the engine light flashing error. What could be the problem?
My customer has a 2012 Honda Odyssey had this exact problem a few years ago Honda did the rings and plugs for free under the recall. While they were doing the recall we inquired about the Timing Belt and they did the Timing Belt for half the price. Vehicle now has 265,000 miles on it no misfires about to do the Timing Belt again.
Good Job.
Imagine that you have a shorted ignition coil which is number 2, then may fry driver 4 and 5!!!!
Why you don't test an ignition coil by hand external.
If that was the case, the driver is already cooked on the number 2 and an ECM replacement was coming anyway. Right?
@@ScannerDanner
Yeah.
That's right.
Thanks alot.
Great...!!! 👌
Merry Christmas Danner’s! Hope you all have a great Christmas and remember what the day is really about!
Super good vid. I liked the use of the amp clamp showing primary pattern. Also the order of the steps. Thank u! Excellent editing and camera work Caleb!!
Would it not be simpler to move the plug and coil from the suspect cylinder to two good cylinders?
Yeah, that what I usually do, swap the coil to one cylinder and the plug to another. That way you know if the misfire follows the plug or the coil. BTW, another shop just threw some coils at it and then sent to your shop??? Didn't even pull a plug to look?? That was the extent of their diagnostic??? 😲😲
Next time for sure!
I haven't gotten through this video but can't you still adjust valves on these things ?
Danner. Crack me up when you start doing coil swap. lol. But I guess you do what you have to do to fix the car. And most importantly time is money. 😆
Whatever works right? Especially when secondary KV on these coils is sometimes impossible to acquire.
how can he tell if its a secondary misfire ?
Perfection at its best.,...I don't know how many times I've used cylinder drop test to find misfires....
Happy holidays to you, your brother and Kaleb. I'm looking forward to more videos in 2022.
Great video guys as always and i agree new plug drive it.Be safe everyone and Merry Christmas and praying a better New Year.

question. 2014 chrysler 300 3.6l what about if you swap a good working coil with good signals power and ground,
swap a good working spark plug, a tested good injector, with +10 condition only on LONG trims, SHORTS trims normal on + & - numbers, and cranking sound evenly??
ScannerDanner good Morning 🙏 🌄 ✨ Have a great day 👍 Take care ScannerDanner 👍
Great tutorial thank you 🙏 👍

From Nick Ayivor from London England UK 🇬🇧
Great video Paul, learning something new every day.
Good ol piston ring bulletin extension.
See that!! This is proper execution, excellent video!
Nice video. So the 09 Honda engines have a piston ring problem that causes oil burning also? My wife drives an 07 Toyota Camry and it has the same condition. It's never given us any trouble at all. I just have a reminder on my phone to check the oil every weekend and usually it's just a little under the full line on the dipstick so I just top it off every weekend and keep on driving.
Hey I have same car check engine light get on . Miss fire ce 4,5 and 6 I changed 6 spark plugs and 6 ignition coil and I cleared the codes and after I drove it 69 miles check engine light went on a gain. What do you think about this situation???
HI PAUL DANNER AND HIS SON,
YOU ARE BOTH # 1 TEAM ON YOU TUBE, YOUR APPROACH WITH LAMBDA NUMBERS IS A GENIOUS IN THE MAKING. I CANNOT STRESS THE EFFECT OF BEFINITS TO THE AUTOMOTIVE
INDUSTRY. YOU REALLY MAKE MY DAYS.
YOU ARE THE THE SUPREME.
GOD BLESS YOUR HEART AND SOUL FOR A MAGNIFICENT JOB. THANK YOU
Thank you sam
Never knew the cylinders on this were numbered this way. Like Ford Triton. Low tech way to know: unplug first and last cylinders for one bank and check scan tool.
I didn't know Honda Accords are known for burning oil (ring issues). Which model years have that problem?
Honda had a recall for a few cylinders for the oil burning reason. Lucky tech that got those warranty pay jobs, lmao!!!
I looked at a car about 3 years ago lady said she just had an oil change and she got the car home next morning no start pulled the plugs (v6 GM) all plugs coated in oil like all the cylinder where filled eith oil check oil level it was good not over filled 🤷♂️ she scrapped the car never got to taer down and figure out why it was like that
Hi am a Automobile engineer. I am watching from Bangladesh.i need Automobile job in any country please Help me
Some of these special tests on scan tools are useless. Kind of like the GM VVT special test. I can control it but by the time I can look at anything the test has timed out and can’t be run again for like 60 seconds
Honda engines hardly go beyond 160K miles. I have seen many many engines burning oil around this mileage.
I had a Honda V6 pull into my shop a month ago with over 500,000 miles on it. It had a slight misfire due to really tight exhaust valves but after the valve adjust, the thing sure ran nice. I think the secret to that V6's success was consistent oil changes, and no cylinder deactivation.
and this is why i do not buy a used car from a shady car lot, LMAO, cheap bastards, just replace the plugs.
Great video and content like always. Any book discount for Christmas =) Take care
"Yes!! 1000% of the time!" Hahaha awesome
😂
Paul would it be okay to put anti fouler extension If it's burning oil only on 1 plug help and extend the duration and life of that plug?
hello, the number 5 ignition coil is from Honda Civic 06/09
This problem is caused by the Honda VCM/eco mode. There are products you can by to disable the eco mode and solve this problem. In 2013 a class-action lawsuit was filed against Honda, 1.6 million vehicles between 2008-2013 had been identified having potential for high oil consumption and misfires due to VCM Operation on 3.5L V6 Engines. Honda extended the warranty for these vehicles but did not correct the problem. This did not include the millions of vehicles between 2005-2007 that also had the same defective issues and had owners complaining of repeated failure of costly motor mounts to VCM operation, damaged transmission torque converters, fouled spark plugs and excessive oil consumption at the rate of up to 1 qt for every 1000 miles. Honda claimed this was normal.
Just add oil. And new plugs every half year. 😁
Honda dealer tech here knew the issue minute I saw it was a v6 rear bank had luck at the dealer soaking the cylinders with a solvent
Those Honda's famous for spark plug failed....
I own a 2006 Honda Odyssey with this same engine. I purchased it brand spanking new. I am anal when is comes to maintenance so bad that I change oil in my cars every 3,500 miles or 3 months. So as I noticed that this engine would burn oil about 3/4 quart every 3,500 miles even while using synthetic. So I always checked the oil. Then at about 60,000 miles I heard about a device called VCM muzzler. I got one on Ebay that you solder together and put it on the car. It stops the VCM from engaging. The kit I got comes with several resistors and a suggestion on the ambient temp and resistor combo to use. I live in an area where the winters are mild but the summers can get hot. The resistor lowers the voltage back to the VCM so it will not engage unless the engine temp gets to 180 degrees. Your temp guage will show that the engine is running a little cooler. For me it stops the VCM 95 percent of the time from engaging. Oh I have changed the spark plugs at 65k and at 120 k and no black soot on spark plugs. If you use too high of resistance you will get a check engine light. When installing the muzzler you must install it when the engine is cold.
What the heck the other shop never check that most likely this engine has to get reringed
Mui. Bien master. Excellent diagnosis. Mui. Bueno tec
Great and quick diagnosis
☆☆☆☆☆
Nice case study I would swap coils and plugs
Snap on is right behind you man grab yourself another battery 😂
me at this point I would replace all the plugs and coils and only use OEM parts on honda
great video Paul,i liked the way you said your brother probably won't even change it.!! WHAT does surprise me is ,THAT he doesn't HAVE THOUSANDS of PLUGS just lying around. i mean what the hell? What is he ?A NEAT FREAK? does he throw all the old parts from cars away? haha i used to wrench 40 years ago and i bet i have a plug or wire from a model A car,ya the big fat ones,you never know when some restored MODEL A gonna brake down buy your shop.OH ya i also have one of those piston sand blaster,haha love your vids man.
Thanks man, really appreciate it
Merry Christmas to you and ya family ScannerDanner
Lol, don't be a parts swapper. In this situation it is the fastest for a diag.
Hello sir I am mobile from Bangladesh
Sir I am global and Bangladeshi people and Europe phone number please
Icon tennis player video please
You simply Great bro...Nice video...
Paul/Caleb,
Great diag, fix and video - thank you! I would have liked if you could have re-done the cylinder drop test after Danner sandblasted that plug just to prove the fix. Oh well no biggie.
BTW what is the deal on the old Fox Mustang that was behind the Honda? It looks like an '86 or older 'Four Eyed' 5.0L Mustang. Not many of those early EEC-IV babys still around.
Paul (in MA)
Back in my younger years when engines and ignition systems were less hi-tech we saw a lot of worn out engines with this kind of issue on a weekly basis, in those times common trick was to fit a hotter (sometimes called a softer) spark plug. We would replace say an Champion N9Y with an N12Y as a short term fix.
That was the first thing I was going to suggest. It's worked for me many times.
They also used to make a sleeve you could screw the plug into then install the whole thing. The sleeve shrouded the spark plug shielding it from the oil. You would have to periodically clean the sleeve though but you didn't go through plugs as fast.
It likely wouldn't work on an coil over plug scenario though.
