Unreal
I take it he didn't find the leak before he blew himself up lmao I'm sorry theses days with people u mite be telling the truth. Thats kinds scary 😨 lol
Swami discusses uses of the word f***
I wanted to do the same with my 2000 gmc sonoma
Finally, an actual teacher to teach all of us old school mechanice, these modern computerized cars. Thank you Sir, Salute.
Thanks, I appreciate you taking the time to comment
Well explained.We need more professional advisers like this man on you tube.
Absolutely one of the best instructors on UA-cam. I appreciate the time you take to instruct and teach. Thank you
First thing to do, replace the gasket on your gas Cap. Esp if the car is old. this will cost you around $20 or less. I got this evap code, reset it, a week later it came back, I checked my gas cap and it didn't really feel snug like a new one, so I checked online and I found a recommendation to replace gasket. worked for me.
Good to see you again. The quality of your instruction is superb!
Good to see you back again. The way I was taught, basically open loop means that the computer isn't using the oxygen sensor/s to determine the fuel control strategy. It uses the TPS, MAP, MAF, and all other engine input sensors, but ignores the oxygen sensor/s reading. Closed loop means it uses all of the above plus the oxygen sensor/s.
great instructor I like the way you explain the system before jumping into the repair well done.
Excellent Video ... I appreciate him giving the thinking and diagnosis process!!
I thought the info was very informative and it helped me to understand the evap system much better. Thank you for making these videos!
One of the best explanations i have EVER seen.... you explained the entire cycle.... I keep getting "Depollution system faulty" in Peugeot (its a plague in these cars!), i even have thier Computer the agency once no clue yet.... it causes the car to go rough and engine to rattle. I'm doing the smoke trick near engine and going to check the fuel pump (checked the fuel filter seemed new, and cleared it myself even)
Initially I was disappointed not seeing the direct fix, but once you got to the details, I began to appreciate the video.
Really informative and educative.
Not sure why people are saying this is too long.
It’s a great explanation. Nice to have an understanding. I don’t need the expensive machine because most auto parts stores can get you the code. But I do like to understand the big picture in the system that I’m throwing parts at.
Thank you for making the video. You are a natural teacher. I really appreciate the background information that really helped me understand how the evap system works. I assume that, if the purge valve had been good then the next step would be to pull and check the valve by the gas tank. I think I will be able to fix my car now thanks to your video.
Excellent teacher! That video time flew.
Awesome video - really helpful in understanding the foundations of the problem. Thanks for making this!
Very well done video. Good explanation of the evap system. If you don't have a smoke machine this is fast and easy way to troubleshoot the system.
I'm ready for part 2....glad to see you posting again
Should show how to with a simple cheap machine like this one:

Thanks, You are by far the very best teacher on UA-cam . I learned a lot from your videos.
Next to chris fix yes
Thanks for this video, great explanation of the system. Thanks for sharing your knowledge.
Thank you for your time and efforts stay blessed
Thanks for doing this video. You always do a great job. I know to make a video takes time. I appreciate you sharing your knowledge and experience.
Very well organized and executed. Good job.
This man is a natural teacher.
GREAT TEACHING, I AM REALLY LEARNING ALOT, FROM PART 1 and 2, I also have a small leak, engine LIGHT IS ON, going to test my test my PURGE VALVE.
Great comprehensive instruction on EVAP systems and their repair. Much appreciated!
nice explanation on how the evap system works!
IT is always good to see you back with videos full off good info always.thankyou
I like your critical thinking. You used the knowledge of the computer to help you determine a solution. GREAT!
Thank you. Very clear & informative!
Highly appreciate the video! Great explanation
Thank you for posting this video!
Best explanation I like your way of teaching thanks a lot
I am glad you are showing how to fix a leak made easy,
This was extremely informative.
Great explanation video and visual examples! Thank you
Awesome video, both parts. I don't consider myself a "car guy", just a "cheap guy". I hate to pay someone for repairs I can do myself. The evap system was always a mystery to me. Thanks for the thorough explanation, so I'm not just shotgun throwing parts at it. My hat is off to you kind sir.
Great video. Really shows how generic troubleshooting techniques always remain valuable. A note to young mechanics, use your head and pay attention. Your time will be spent less on troubleshooting and more on helping your clients and that makes for return customers.
Thank you!! All you ve said is important and interesting.
Awesome video ! You are a great teacher .
Great video, thanks for the expert advice
GOOD JOB i like you explanation very clear thank you
Great video. Thanks!
He broke it down he's very knowledgeable and it makes sense I gave be a lead thanks thanks
Very informative. Thank you
sure appreciate your videos wish i had more years of life left to understand all you do, even then i wouldn't, memory is a downfall of mine. thanks for your videos. you know allot electrical, mechanic etc. thanks again for illustrations.
You'd make a great teacher. That was an informative, succinct description on EVAP. I do pray that my trouble are only a gas cap with the p0456 code. Now onto part 2
If it’s a Toyota/Lexus 99.9% chance 😂
THANK YOU FOR THE VIDEO YOU ARE A GREAT TEACHER
Pop, your a great teacher
Great explanation of the system and troubleshooting
AWESOME information here!!! Thanks for sharing your knowledge and experience!!!
you're welcome, thanks for commenting
INVALUABLE CONTENT! THANK YOU👍
THANK YOU THANK YOU THANK YOU!!! This was totally the problem.. Changed the purge valve $42.00 @Advance Auto.. 15min to change.. Mechanic charged $40.00 for his time.. Awesomeness.. Pass Georgia emissions no problem!!
Very informative now I kinda understand how it works it will help me no what to look at thanks
Best explanation Sir.
Thanks💐❤️💐
This is so amazing. If you can pay some attention and listen, you will end up saving a lot of money, but then again you need some common sense to do that. Absolutely awesome. Thank you sir.
Yeah people are too glued to social media for that
You truly understand your craft! If you where anywhere in upstate NY you’d be my mechanic and my whole families until we died
Thank you Doug, that is a great compliment and makes all my work worthwhile.
GREAT Content Videos Thank you so much
Very well explained thank you
I haven't seen a video from you from so long!! your videos are always great and informative !
Great post. I just hate the fact that these critical valves (purge and vent) are such a pain in the butt to get to. My 2006 Avalanche is a real pain...
I like the way he explained he has a lot experience
Thank you. Great video
I can’t believe I’ve never seen this video. Oh well catching up now! Thanks Dwayne!
Great video help me a lot,thanks
Very informative!
very educative. Thank you Regards
Nice review, Duane!
Great info. Thanks.
great vid as always...
Very helpful thanks I'll will try to doet myself.
thanks this video is very helpful.
I've not even watched the video yet but we have missed u! welcome back, sandy from Scotland
BEFORE you watch this long video, which is well done, know that it is not about "How find a small evap leak without a smoke machine" but rather is is about how to understand the evap system and use an expensive professional scanner, IT IS NOT ABOUT HOW TO ISOLATE A LEAK (hopefully that is in part 2, yes there is a part 2 even though this vid is not called part 1.
Interesting!, Thanks so much 👍
Thanks a lot it's very helpful
Thanks for explaining how the EVAP system works. I like to have knowledge before taking my car to a shop. Ignorance is costly. ☺
thanks for this detailed info
sailfin sculpin yay
A very good and informative video, so funny some people commented the video that is not helpful or saying that too much of a talk. If you guys are only thinking of fixing the problem without understanding what is happening to your engine there's two things thst might gonna happen, either your car engine problem migjt get worst or you fix it right. I like the way he explained everything as i clearly understand how things works👍. By then if you send your car at the shop, those greedy mechanics will not be able to fool you the way they steal money from our pocket. Regarding with the tester he used, he's not promoting and or selling what he's using i guess, it's just that, that's what they are using in their shop? We shiuld be glad and appreciate this kind of person sharing us some information what to look for if there's some problem in our car engine.
Thank you. You said it perfectly
Great video!
outstanding helped me
Excellent tutorial. Thank you so very much~! I'm a 70 year old woman and my 40 year old daughter and I are determined to fix this problem. LOL. However, if I were near you, I'd bring it to you for a fixin~!!
I like your attitude, you can do it. Let me know if I can help.
Perfect video I just notice I think someone else mention your channel before I see why
Very nice explanation
Good stuff... Thank you
Good stuff man thanks
Thank you, will try it tomorrow.
With $ 10.000 snapoon scaner.
what a masterclass!!!
Excelente, muchas gracias.
Translated means excellent thank you very much
Educational video !!!
this is very professional (MTM),I have watched your videos for years , Im glad to have found you videos and teaching, I have made a donation. I will subscribe t o your channel
Thanks for your support I really appreciate it.
Great video
Wow, not surprised, but people have short attention spans. I guess this sorts out the good mechanics from the mediocre ones. Really appreciated this video and thought it was well instructed and well produced. The point he makes (which those with lazy attention spans will never understand) is that a little critical thinking in advance and a good understanding of how the systems work saves time and parts costs in the end, because rather than just diving in and randomly swapping out parts (at your customer's cost), we try to pinpoint the most likely cause of the problem from the start using the information the car is giving you. The answer is there - but you need to learn how to analyze the data first. Too bad more mechanics don't take this approach. Will be watching more of his videos. Totally impressed.
Thanks for you comments, Glad you understand the bigger picture
Now that's an absolute certainty for me.....
"Watching more of his videos "
mmmm,,, I guess I still keeping my 1975 Chevy,,,, those new vehicles have so many sensor$,,,
it would be nice if they taught that in school, 'critical thinking' thanks and many Blessings Duane : ) excellent presentation
You guys awesome make jobs easier. 👍
Buen video amigo exselente maestro
Great explanation for the EVAP syystem. Always goes bad on Fords
glad you liked it, thanks for commenting
This is all for OBD-II vehicles that have scan tools, PID's, and enhanced monitors. OBD-I (vehicles made before 1996) have it much harder. Still a great video. The diagram and description of the evap system is spot on. Not all vehicles have electronic canister vent valves or pressure sensors. Have to take all of this into account when diagnosing a vehicle and adapt these procedures for the vehicle design that you are working on.
+DJDevon3 Never seen a pre-OBDII vehicle set an EVAP leak code...so there's nothing to worry about! On that note, I find it silly for the "Check ENGINE" light to come on for issues that have nothing to do with the engine/driveability.
motoYam82 Not setting an evap leak code (because it doesn't exist on your OBD-I vehicle) is even worse. Good luck figuring out there's an evap problem. :P You might get a faulty solenoid code if you're lucky but that's about it.
+DJDevon3 But the system itself is simpler with no canister valve, since there's no need to check for leaks anyways. The only electronic part is the purge valve which could fail mechanically and not set a code. Otherwise you just use your nose to check for leaks...if it smells like gas fumes, you have a leak lol
I dont have that costly machine either, nice info if you have that code reader , yes a waste of time for most of us. Thanks just the same
