My neighbor used the Bic lighter test on his EVAP hoses....once. I miss him.

[@niceguy192]

LMAO

[@jackhodges514]

Unreal

[@vincentnewton697]

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

[@darkknight8244]

I wanted to do the same with my 2000 gmc sonoma

[@Matt-vb2jo]

Finally, an actual teacher to teach all of us old school mechanice, these modern computerized cars. Thank you Sir, Salute.

[@realfixesrealfast]

Thanks, I appreciate you taking the time to comment

[@govindagovindaji4662]

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~!!

[@realfixesrealfast]

I like your attitude, you can do it. Let me know if I can help.

[@MrAmisto]

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.

[@originalabesha7480]

Well explained.We need more professional advisers like this man on you tube.

[@ozzstars_cars]

I'm ready for part 2....glad to see you posting again

[@globalcommerce7654]

Should show how to with a simple cheap machine like this one: kzbin.info/www/bejne/aoOXgmyPYtiKY9U

[@meanpicker]

I thought the info was very informative and it helped me to understand the evap system much better. Thank you for making these videos!

[@nunapitchuk]

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.

[@joemikos9155]

Absolutely one of the best instructors on KZbin. I appreciate the time you take to instruct and teach. Thank you

[@advancednutritioninc908]

Excellent Video ... I appreciate him giving the thinking and diagnosis process!!

[@ronniecullop4099]

great instructor I like the way you explain the system before jumping into the repair well done.

[@dmorley100]

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.

[@roberthiggins1468]

Good to see you again. The quality of your instruction is superb!

[@iluvwhtchix]

Excellent teacher! That video time flew.

[@daviderhahon]

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.

[@omyajt]

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.

[@geekdiymechanic4539]

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.

[@hammerhead6537]

Thanks for this video, great explanation of the system. Thanks for sharing your knowledge.

[@quirksilver5006]

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)

[@johnadams3152]

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.

[@timsain925]

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.

[@luisaliceaortiz7791]

Thank you for your time and efforts stay blessed

[@dalecocca]

Awesome video - really helpful in understanding the foundations of the problem. Thanks for making this!

[@samd410]

Thanks, You are by far the very best teacher on KZbin . I learned a lot from your videos.

[@jaymeschappy1965]

Next to chris fix yes

[@tonytiger8318]

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

[@realfixesrealfast]

Thanks for your support I really appreciate it.

[@eyejedi]

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.

[@jgeorges3061]

IT is always good to see you back with videos full off good info always.thankyou

[@queenempress2541]

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!!

[@reginaldking3272]

I like your critical thinking. You used the knowledge of the computer to help you determine a solution. GREAT!

[@jtleon7086]

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

[@nordicpride9708]

If it’s a Toyota/Lexus 99.9% chance 😂

[@archie34734]

Great comprehensive instruction on EVAP systems and their repair. Much appreciated!

[@j.santosh.l.6386]

Thank you!! All you ve said is important and interesting.

[@BoreusRex]

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.

[@johnhough7535]

I am glad you are showing how to fix a leak made easy,

[@scooter12368]

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.

[@Ermagawd]

You truly understand your craft! If you where anywhere in upstate NY you’d be my mechanic and my whole families until we died

[@realfixesrealfast]

Thank you Doug, that is a great compliment and makes all my work worthwhile.

[@12marcomorales]

GOOD JOB i like you explanation very clear thank you

[@StonnieDennis]

Great video. Thanks!

[@EAPonce-qr7sw]

Great video, thanks for the expert advice

[@mikewithers7685]

Awesome video ! You are a great teacher .

[@crawford323]

Very well organized and executed. Good job.

[@knwrdeeptube]

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.

[@nordicpride9708]

Yeah people are too glued to social media for that

[@danieljamar5639]

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.

[@sandyande]

I've not even watched the video yet but we have missed u! welcome back, sandy from Scotland

[@rolandvaldez8228]

Very informative. Thank you

[@coachwilson5967]

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...

[@altiro4ever]

THANK YOU FOR THE VIDEO YOU ARE A GREAT TEACHER

[@terrywin2661]

AWESOME information here!!! Thanks for sharing your knowledge and experience!!!

[@realfixesrealfast]

you're welcome, thanks for commenting

[@joshuatoms968]

Very informative now I kinda understand how it works it will help me no what to look at thanks

[@46JennyGirl]

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.

[@realfixesrealfast]

Thanks for you comments, Glad you understand the bigger picture

[@daviderhahon]

Now that's an absolute certainty for me..... "Watching more of his videos "

[@JoseJimenez-bd8pv]

Great video help me a lot,thanks

[@2pacnasgame]

Perfect video I just notice I think someone else mention your channel before I see why

[@DJDevon3]

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.

[@PineHollowAutoDiagnostics]

+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.

[@DJDevon3]

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.

[@PineHollowAutoDiagnostics]

+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

[@hsarwah4602]

thanks this video is very helpful.

[@Aybak404]

Best explanation Sir. Thanks💐❤️💐

[@yvetterenee8256]

Thanks for explaining how the EVAP system works. I like to have knowledge before taking my car to a shop. Ignorance is costly. ☺

[@x7.daniel549]

Thank you. Great video

[@phartblossum]

Great info. Thanks.

[@moradhaouchine6694]

Everyone is a teacher, but not everyone is a good one, and you Duane, you are a stand out! I have a few questions. In order for the monitor to check for the leaks, both valves have to be closed. How did the canister vent valve close? since it's open when the engine is off. On the large & medium leaks, system passed, , how do you interpret the values shown? what I mean, how would you know whether those values are optimal, or on the borderline of a leak? Again, thank you for video and the wealth of information

[@realfixesrealfast]

Thanks for the kind words. Great question but not an easy quick answer. The ECM has built-in controls for the systems it monitors. So the ECM closes the valves when it starts the test and opens them based on the test results. You would need programmer instructions to get the actual answer. Keep in mind all electronics are simply voltages and ground. All ECMs are binary devices which means they can only read 0's and 1's, not voltages. All data is converted to 0's and 1's and is either an input or an output. Programmers ask the questions as "if, then" format. example, if the valve is open and the test is requested to run, then close the valve. The test runs, results are reported, and the next "if" question is asked. The EVAP test answers are based on time. For example, how long did the vacuum hold? The answer determines the next response (action).

[@yhenn25]

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.

[@PineHollowAutoDiagnostics]

Nice explanation, Duane. I've never found Freeze Frame data to be valuable for diagnosing EVAP systems, since the monitors generally run at cruising speed, but the test result/MIL command can be issued at any time...any thoughts?
