You, my friend, are the type of mechanic that gives us all hope that honesty and knowledge of your craft still exists! Thank you for sharing this video.
I'm a retired technician. I've worked for dealerships and independents. I never hear mention of the service writer/manger miscommunication causing some of these customer problems. Usually service writers know little or nothing about cars. They are glorified salesmen! I've watched service writers call customers after I've given them a diagnosis, and tell the customer a completely different story! Be aware, not all comeback problems originate with the technician. 🚗
Hey Ed, could not agree with you more! So much can get lost in a lack of communication. Unfortunately it's not my shop, not my car, so I wasn't involved. I went off of the facts I had, previous invoices and a broken car. And of course the customers side of the story. But you're right. The shop or tech may not be at fault here. Mike Becker, Senior Instructor
Anon Ymous Used to see that all the time at my previous job. It was mainly one guy doing it and nobody could touch him. Management loved him, he was top 5 salesman in the country.
I work for hyundai and i see the same stuff you all said. They they sell a 30 or 60 service and then i present them with something else the customer needs and should be priority and they blow it off and make it as if the customer declined the work.
@@GoTechTraining I have a 2001 Ford E250. No code no check engine light, but will not pass the ready test. New gas cap, New hoses, valve seem to test ok. Any ideas?
I a not a certified mechanic... I try to use common sense when I work on my cars. As soon as you started the smoke test I was like "Make sure you test the part you bypassed!!!" Sure enough, you went back and tested it. YOU are a smart mechanic and use common sense. Customers would be wise to listen to your opinions and suggestions. Good job sir.
@@frnkjones40Im 16 trying to fix p0455 I bought a fog machine and cut a oil cone cup to attach it to and made my smoke machine. Replaced the cover centrifuge, purge valve, intake manifold, oil drip pan, cam plugs, re hosed vacume lines that were cracked, you are lazy and don’t want to see your car run, i will make my car run and refuse to pay someone to do something I can, anything Is possible be patient and research
Cant cross your fingers lol. Find your leak and show u can do it all, people won’t do work on my 2008 c300 and overcharge me because they think I have money. Poverty will drive any man to do anything. U got this
@@davidmendoza5522 Lazy??? Kid you don't know me and you don't understand English well enough to respond properly to what I said.There was a compliment in there and you missed it. Lazy people don't pull their engines and rebuild them by themselves from a bare block and reinstall. Lazy people don't drop and replace their transmission at midnight in the freezing cold by themselves because they need that car for work 6 hours later. They
The signal wire doesn’t send 5v to the sensor, the Vref does that, the Vref and signal are just shorted together inside the PCM for diagnostic purposes Chrysler does the same thing, while Ford and GM do not if you measure the signal wire in those cars it will read 0v. You had the right idea just explained it slightly wrong and it’s a pet peeve of mine... still love the videos and you’ve taught me a lot over the years!
This dude rocks! Ive hardly ever seen someone with as much knowledge and professionalism as this guy has. Two thumbs up man. Keep the videos coming. U are a shining example for everyone who has to work on cars.
im giving you more than one thumbs up ,one for the purge solenoid ,fuel pressure, sensor, one for the cracked fuel pump,one for the tip about the rust causing pressure ,one more for mention the abs sensors affected by rust...I will like to subscribe again if I could ...I remember one of your videos showing how evap works...thats a big key how to diagnose this type of problems...thank you Mike...from phx az
Every one uses a smoke machine for the smoke and its a great feature , but the little ball will tell the true story about evap leaks , if it doesn't drop to the bottom you have a leak! The soapy water is the way to go on hard to find leaks ! Great tips.
The fuel tank pressure sensor was broken at the time it was removed and replaced. It happens a lot if you are not carful when you remove an old sensor.
Great troubleshooting by taking the time to know how the EVAP system works and systematiclly isolating the problem to a physical crack and faulty component. This is what separates you from the rest. Nice job conveying the story.
Just subbed ... always refreshing to see a guy who not only is thorough and checks service manual/tips ... but also has good critical thinking skills .... evap systems are a pain ... and there is certainly simpler ways of achieving better rebreath of vapors ... but they don't call it the "Money Light" for nothing ...
Thank you for posting this to the public. You just gained a new follower, simply because you followed proper procedure. Not only that, but you show how much you genuinely care about your customer, and doing what’s best for them. Job well done, son.
Just want to say thank you for how thorough this video is. It helped me solve an evap code on a complete different vehicle. The hose connected to the bottom of the purge control valve had a sizable tear, not visable from the top of the engine bay. Followed your method of methodical visual inspection and immediately found the cause before throwing money at replacement sensors and parts!
You made a believer out of me with one video. I do my own repairs as often as I can thanks to guys like you that teach me how. The best part of the video was knowing that you had the customer in mind. Too often people who do repairs (on all kinds of things, not just vehicles) have only their profit in mind.
Hey Mister Handy, for sure! I feel like we saved this one, pulled him from drowning in the deep end of the parts pool. haha! Mike Becker, Senior Instructor
When pressure drops indicate a leak in areas you can't see to test with soapy water you can sometimes run your hand over the hoses and feel the leak. Or stethoscope the leak. Sometimes if you feed the smoke machine from the filler neck you may be able to see smoke that will not be visable after going thru the charcoal canister. You have a really technically literate following. I have to watch parts several times to absorb the information, the same with some of the comments. Not a criticism, but a compliment. I solved a witch of a problem P0455 with your assistance. Thanks.
Excellent video as usual my friend. Great way of breaking down the process. Highly recommend your EVAP videos to the younger techs coming into the shop who want to expand their knowledge and truly grasp how the system works.
I can’t believe how many shops get this wrong! They should definitely watch your video series on EVAP,that way they will learn how easy it is when you know what you’re doing! 👍
Made my own smoker - found a smoke trail coming out the EVAP TEST PORT - used the Purge port since the purge valve was tested - new - using the LASER Idea I noticed a hazing of the RED beam. Fixed LARGE leak 455
Thank you I stopped calling myself a mechanic when all these electronics started to be added to vehicles and the diagnosis of them varies inconsistently. And the cost of the diagnostic tools were to much for me. As a parts changer now it's more frustrating to not look like I'm dragging the job on to make more money. That's why I love UA-cam and people like you to get right to the issues of these modern day overthought vehicles that come with parts that are designed to fail in shorter periods of time. As one mechanic once told me; they make more parts than cars
Thank you for taking the time to demonstrate how to apply basic fundamentals utilizing readably available resources to perform a successful diagnostic and repair. The other lesson I took away from this is the importance of Integrity, Accountability, Transparency, Ethics…all of which appears to be at the root of why this particular car is in your shop.
The absolute most in depth, honest, human I've had the pleasure of watching from start to finish. Believe it there's a boat load of non conducive jargon idiots out there but not here on this channel. So impressed that I donated based on professionalism alone
Good Presentation! I just ordered a complete Fuel Pump Assembly, for my 2006 Hyundai Elantra HD. I did smoke test fuel tank, with Smoke Test, without theVacumn gauge system. There was no visual leakage around top plastic fuel pump assembly. Anyway living remote I decided to replace complete Fuel Pump Assembly, just in case, either the Fuel Tank Pressure sensor is faulty or the plastic fractures around the lock ring on removal . Hopefully my DTC and CEL, issue will resolve. I've replaced every other sensor, new fuel injectors, CVVT solenoid valve, Purge Valve, Throttle Body Assembly, because it failed smoke test(leakage from butterfly spindle shaft) , both sides. Excessive wear, made no difference. PCV valve, Rocker Cover Gasket, Vacumn lines engine through to purge valve. The fuel pump seems to possibly be failing. Put F-10 , fuel cleaner treatment through, still not cleared. New Ignition Coil and Spark Plug Leads and Spark Plugs. Hopefully the OEM fuel pump assembly will kill this CEL
Good work! Wish I could count on most shops to be as thorough. If you get incompotent mechanics, you can easily just get lots of tests and parts passed along to customer & still not fix the problem, which appears is what happened here. Good work, and I better understand how these systems work now. THANKS & it WAS a very good subject for a video. I'm sure the customer was feeling leary about yet more parts being needed when you first called, but everything you did was necessary and proven so, because it lead you to finding the problem and fixing it. And I'm sure your explanation would make sense to them , as it does when watching the video. If you are a DIY person, with no access to expensive code machines and access to manufacturer's information, you expect tht you might replace some things that are not needed, but you expect that when a garage is charging good money for hourly rate, etc. that those resources ARE BEING PUT TO WORK. I've recently bought a cheap code reader for about $25 along with my long time practice of having a REPAIR MANUAL for the cars I own. Together, these have been an invaluble tool for a DIY person, with a little info, it allows sensible checks, and spending a lot more on a more expensive tool isn't going to help me much, because I can't afford a bunch of speacialty tools & books, so would need a shop to do that anyways. And checking out some videos on my problem has been a nice addition from modern times, that often helps you know what to expect when taking things apart.
That 5 volt at the sensor wire when unplugged is the bias voltage the ecu uses to sense if there is a break in the wire or sensor. There is a relatively large resistor between the signal circuit and a 5 volt supply inside the ecu. There is normally a small current running through the signal wire when things are in order, and with current comes voltage drop. The voltage drop over the biasresistor makes the bias voltage magicaly "disapear" before the eyes of the "signal voltage reader" and it only sees the voltage from the sensor itself. So the 5v on the signal wire isnt changing with pressure. Its voltage being dropped inside the sensor between the 5v ref and ground that is "fed" up the signal wire that the ECU senses. So. If the ECU sees 5 volt at the signal wire it knows its either because there is a break in the circuit so that there is no current flowing, Or the sensor is broken (it never gives 5 volts out when its OK. Neither does it emit 0 volts. Its probably more in the range of 0.5 to 4.5v or there about)
Great thorough diagnosis and explanation of how the system works . The visual and COMPLETE inspection of the SYSTEM is critical . We may not have the complete story , BUT if they researched , they would never of had to drop the tank . It seems they were quick to slam in parts without going in depth . What scares me is the ECM " diagnosis " . If that went in - then what ? How do they get away with it ? And now my lesson learned on from my old 1987 Celebrity , 2.8 L . It intermittently ran lousy . Vacuum dropped under 12 lbs . at idle . I ran tests on everything . Changed a fuel filter , which wasn't restricted . After studying the shop manual , I plugged the evap purge solenoid and drove it for days with no problems . The solenoid would stick open instead of being pulsed by the ECM . I don't know if over time and rough roads , RR tracks , etc. the charcoal gets pulverized and makes the valve stick or if it just wears out . I don't know if that would skew the fuel trim numbers when stuck open from the vacuum leak ?
Hey Bill, thanks for watching! You're right, the tank never should have come down. As for the purge solenoid being stuck open...the trims will depend on the saturation of the canister. Typically you'll see a lean condition. But rich conditions aren't unheard of. Mike Becker, Senior Instructor
Hey Braulio, i'm in Wisconsin...so it's an even further drive...but I'll take a look if you get it here 😉 thanks for watching! Mike Becker, Senior Instructor
@@GoTechTraining sure thanks your rock man I hope soon you'll get like 10 million subscribers and and get paid like you should by UA-cam and the near future I will drive all the way out there to see you if I don't find anybody can fix it
Same here. I need someone to fix my vw golf !! Mine doesn't have a cel coming on or anything ! Idles really rough puffy idle. No smoke. Shakes the entire car and engine. Just lost at this point...
@Sam S I checked the to make sure the cel works and it does. Just hasn't been long enough or bad enough symptoms for it to kick the light on yet I guess.
I'm a tech at a Honda dealership. Honda had an issue with cracking fuel pump modules extremely similar to this. I've even seen it actively leaking fuel while running; interestingly enough, I don't recall it causing evap codes. Good find!
@@GoTechTraining You're welcome,I got hosed before and that's when I decided to get to know a little about what makes these things work.I'm glad I did.
Hey Bgregg55, I absolutely hate that about this industry...well, I guess it's every industry...I guess I just hate it when people take advantage of people in general. Sometimes I think it's just easier for mechanics to do it, it's like speaking a foreign language to people who don't know their vehicles. Thanks for watching and commenting! Mike Becker, Senior Instructor
@@GoTechTraining yeah I work in computers and this happens in the IT industry too (though it's less common now the days of $1500 computers are over and everyone has a tablet now). The sad thing about our current society, is that I could be a lot better off financially had I decided to rip people off. I know nothing about cars but always prefer to work on them myself, get info via youtube and forums, and also get my own codes. TBH Everyone who owns a car should buy an ODB2 dongle, they are very cheap. In the end a garage will probably end up doing the work but at least I'll be aware what the problem was in the first place.
Hey Mike, thanks for watching and commenting. You're right...in the world we live in the morally questionable people tend to excel. That sucks! Just because you know nothing about something, doesn't mean you can't learn, right? Sounds like you're doing it right...being an informed vehicle owner. Loving it! Mike Becker, Senior Instructor
I really enjoyed your troubleshooting techniques and the way you broke down the system you are trying to diagnose. I'll be sharing with the guys at work, we build a system that treats cancer and the approach you took in your video are exactly what I was taught when I first started.
With the title and seeing the car in the background as the video started I suspected the fuel pump cracked. Seen many of these with this issue. Awesome job as always!
Sometimes on purge solenoids, I use a vacuum gauge on the end coming from the tank to see if there is vacuum coming out of the purge solenoid with the electrical connector disconnected and engine on.
You are awesome dude. Some mechanics are about the money and do anything but you took the time out and found the issues. Love your honesty and if that was my car you would have been paid your price and tip. Great video👍👍👍
I fixed mine PO455 code on my 08 1500 Silverado for under $40 just today. Took me less than 15 min to swap out a faulty evap purge Solenoid. Engine Light is out.
There’s a a lot of parts changers out on the market that lack. Skills on diagnosing electrical issues. and a lot of customers have been screwed that’s why a lot of people are driving new cars they’ve been burned too many times you have a great diagnostic approach 👍
2K??? I bypassed the charcoal canister. No engine light. Tuned it a week later just in case. Spent $325 on a BlackBear tune and bypassed with parts laying around the garage.
Great video to reinforce my next step. 2012 Silverado, P0455. I cleared the codes, replaced the purge and canister vent solenoids, but although I've driven a few hundred miles and have no CEL, I can still smell gas odor. It's very strong actually. Given it's a pickup and with no access hole to the top of the tank, I was hoping a couple $39 parts would do the trick. Nope. Now I face the dread of dropping the tank on this beast. At least it's off the ground. I expect the same finding - leaking at the access hole for the pump.
Hey Mike, sorry to hear the struggle that you have ahead of you. Hopefully you don't live in the rust belt like me! A word of advice...use as much gas out of the tank as possible. There's nothing worse than needing to drop a full tank of gas. Mike Becker, Senior Instructor
Thank you so much in explaining the whole process on how to diagnose the EVAP system. I’ve been shotgunning parts left and right. I don’t have a smoke machine so I’m gonna just use a vape. It didn’t occur to me that new parts might case an issue also
An apple for the teacher on this one. Keeping an eye on that bubble was critical. I had a Dodge Caravan with a cracked fuel pump in good old California. No rust on the ring. Nudging that ring with the air hammer was also excellent!
Hey Bill, thanks for watching! The air hammer is just what I have to do since I don't have the special lock-ring tool. It works, right? Mike Becker, Senior Instructor
My son-and -law was very sure that the gas tank was leaking in his 2010 Hyundai Sonata. But now he is convinced that the gas pump might be the problem. The car has fail the state inspection twice, and the "permanent code" PO455 keeps showing up. We w'll see wat happens next. Thanks for your video,
I wish u were closer so I could get u to fix my truck! Took it to 3 people already n no luck I know u could do it quick. Wish more people were honest and as good as you..
I've had rust crack a toilet tank much like that. The studs that were built into the tank eventually got rotten from years of condensation and put enough pressure on the tank to split it quite a few inches. Two things to take away is rust can expand in all directions and rust can win at all the worst times.
You are the best mechanic there is I wish you could work on my 04 mustang GT because I am tired of paying for fixes on my car that doesn’t work and I end up paying for more problems
Great job on this, in the case of these other mechs that checked this, they definitely were lacking the proper experience and just kept adding parts to see if the problem would go away or they could be one of those dishonest shops that keep the customer coming back for more which equals more dollars in their pockets. It's embarrassing to say but yes the scam artists are still out there taking advantage of folks.
This wasnt my problem but it was so detailed i couldn't stop watching and gained you a new subscriber I will now go search your videos to see if i can resolve my evap issues and stop chasing DTC ghosts
Great diag Mike. I bet you felt great when you found the actual problems that the other shops couldn't find, and I bet the customer felt even better. I had the same issue this summer on an 07 Mazda CX7. Plastic sending unit cracked and failed evap. New unit and seal but the locking ring went into the sandblasting cabinet and had a fluid film bath cause my customer couldn't wait a few days for a new ring. And now I know why they crack like that. Thanks Mike. BTW I conceded on the Focus for now. All out of ideas.
Hey Mike! Thanks for watching! Sandblasted and coated sounds like a perfect repair to me. My local dealer had one in stock..wonder why? ahah😉 Sorry to hear about the Focus...wish I had some other ideas for ya. Mike Becker, Senior Instructor
Thanks for your ideas thus far Mike. This morning I had a car that was overheating. Had a bad spring style hose clamp and lost a lot of coolant. All fixed now but before they brought it to me someone had told them it probably needs an O2 sensor. LMFAO!!!!!!! I bet you get those comments all of the time from customers.
Mike, you did a hell of a job in your explanation of diagnosing this car. I really feel bad for the customer that spent $500 dollars with a vehicle that still wasn't fixed. And good of him to bring it to you in saving $1600 where it still wouldn't be fixed. Oh, I meant to send you an email about receiving the T-shirts and got side-tracked. Thanks Mike for the shirts and keep up the good work with the videos!
Hey Terry, thanks man!!! I felt so bad for this guy...and to spend $500 to "drop the tank and inspect" when the tank didn't even NEED to be dropped ARGHGHGG! ***Deep calm breaths*** haha! I hope you like the shirts! 😀 Mike Becker, Senior Instructor
Too many shops do that, they see a code and start throwing parts at it. There is some intuition involved but these are computerized things we're dealing with, so you can't always be sure of a hunch like back in the day. The fact that they removed the exhaust and did so much unnecessary labor is a testament to their incompetence and ignorance. I hope the owner took the original shop to court.
Hey Jim, thanks for watching! I'm not sure what's happened since then...the customer was happy with me..not so happy with the previous shop. Mike Becker, Senior Instructor
Man, I would LOVE to work in a quiet shop like that for EVAP leaks:) Nice work bro! You are a professional and you take all your training and experience serious, that's great! You have the right to get upset when a vehicle comes in like this! I assure you, your not the only tech seeing this. There are waaaay to many shops that have no clue on what there doing! Is this okay? Who/where are the people in charge that make the decisions on who needs licensing in the trades? You need a license to cut hair here in MA. Do you think auto shops should be licensed? I think it would weed out the problems immensely! It also may give Mechanics/techs the respect/credit they are due when they put so much into being the best they can! I put my life into this trade! Though, If I could start over. I would have chosen to become an Electrician, Plumber, or even a Carpenter. Far less tooling, more respect, less training, and most get paid more per Hr starting out then a master mechanic does 30 years in. example of what should be done: you want to be a Autotech? Okay, set up a shop with 3 or 4 broken vehicles in it(electrical & driveability). Have the license goer fix each one on a time limit. give the tools(scan tool, M-meter) service info, repair order concerns. Make the diagnosis and report your steps. What about ASE you may ask? ASE is a joke! most shops have the signs up for ASE but have like 1 certification, maybe. You never see those guys(from the "shops") at any training venues! What do you think should be done about this HUGE problem in our industry? then there is You-are-a-mechanicTube :) holy moly.. a bit of ramblin today.. Okay, I'm done:)
This is what i called ASE technician like you mike i trust ASE technicians without a doubt cos why you guys knows what you saying and what you doing in the shops i only goes to auto shops when there's a lotta ASE technician on duty...lol... there's a lotta mechanics out there who really don't know the basics how to fix the problem so today i was at the smog shop to smog my 1990 mazda truck b2200 series 2.2 liter cubic engine it has 143, 000 k miles but didn't pass the smog the fuel evaporative controls functional failed i look the fuel cap is brand new the original owner replaced fuel cap so to make sure there's no faulty smokes coming out from the fuel cap and there's no fuel smells under the hood or anywhere so i was wondering what seems to be the problem when the fuel evaporative controls functional failed mike on my vehicle i work on my car and truck sometimes when minor repairs need to be fix but I'm not an ASE like you are sir.
My employer asked me how to find better industrial mechanics. That's a good question. Frankly could be several ways. BUT. Change the question. What does a master industrial mechanic look like??? Here he Is. He's got a 10th dan Grand Master's troubleshooting mindset. 👍 👍 👍 👍
The benzophenes and sulfur released from the metal during oxidation causes the polyethylene to become more susceptible to .. well.... let's say becoming brittle . Tank and the pump itself are plastic and will expand and contract of course. This movement causes these highly susceptible areas to crack over time. Now that I got that researched , I will say that was an awesome video bud. And thank you for making me read more than I ever wanted to .
Hahahahah so you're saying, in short, that my video made you a better person? 😆 Thanks for watching dude! Miss you and everyone else. Online VISION KC just won't be as fun. Mike Becker, Senior Instructor
I really enjoyed the diagnostics, problem solving, and truly excellent presentation skills. Doing IT for 30 years I can really appreciate a mechanic's skill and it seems a lot more interesting than IT. I just started a job and the work vehicle I have is a Toyota Rav 4 that came with a check engine light, VCS light, and 4WD light on. I couldn't get them to take it in so I put on my cheap OBDII adapter and phone app to get any codes, which was 5. I passed on the codes to the shop next time it went in. It been in 4 times and still hasn't been fixed. Winter is hear and I really want to use the 4WD. I wouldn't be allowed and don't have the skills to fix it myself but I really would like to know what exactly is being done over these visits. If I really needed to use the 4WD my guess would be I could clear the codes and use it until I get them again. Bad idea?
I bet drinking a couple of tall stouts after that repair was well deserved and relaxing. I thought I was watching a magic show with all that stuff you were popping out from behind the cart. Ta-da! Car fixed.
I disagree, it seems that allot of problems start with the service writer or the boss and last we also have lazy mechanics that only worry about making that check. I don't know, maybe these guys spend to much time on the S-O Truck LOL
My 96 Explorer had a p0455, It also had a smell of gas. The steel evap line in the frame had all rust holes in it. I replaced it with 13' of rubber 7/16 gas line and some wire loom to protect. Even though 96 is obd -II, it did not show a CEL for that code. In that year for evap it just records a code internally and leaves the monitor unset. I also disconnected the FPS and just got a code. You could pass in NY with 2 unset monitors pre-99.
Hey, thanks for watching! Interesting how the check engine light wasn't on! I think it's the same by us here in WI. 2 unset pre-99'. Mike Becker, Senior Instructor
@@GoTechTraining I did some research and Ford disabled the leak check for almost all 96 cars (hardware is there, but it isn't in the calibration). So no CEL. www.fordservicecontent.com/ford_content/catalog/motorcraft/obdsm963.pdf pg 15. There is good free reference there for diagonstic stuff!
Lexus dealer told me to replace fuel injectors for cost of $2300 to fix CEL. I asked for guarantee that it will fix and was told no. So drove back. Then bought OBD2 scanner for $99. Got P0983 code. So changed solenoid S4 myself (kudos to UA-cam experts like you) and it’s been running for 18 months so far without any issues. I don’t think mechanics at dealership are experienced mechanics. They may be trained but may be lacking experience needed for a good diagnosis.
Thank you for the very informative video! I am in the process of trying to find a small evap leak in my Pontiac G8 with the 3.6 V6. I'm attempting to diagnose and fix this myself because I know this very same thing will happen if I take it to the dealership. Happened to a guy I know at the tune of 2200 dollars. I am a heavy suspension mechanic so I have a lift to use at our shop and pretty much anything else I need(such as a smoke machine). Unfortunately, I am NOT a driveability tech so I have no clue of what I'm doing. I have to fix the small evap leak before I can fix a PO135 and PO154 code I recently got after my tuner turned off the P2190 code I couldn't diagnose(running rich). It's a mess and I'm foolishly throwing parts at it trying to fix it all. I have a new gas cap, purge valve solenoid, vent valve solenoid, fuel tank pressure sensor and vapor canister for it. This video showed me a few things I didn't know that should help. I can test the purge with a vacuum gauge and smoke test the system now thanks to this video! Wish me luck. I'm going to need it. Car is on the hoist, exhaust, subframe connectors, driveshaft and rear end is out and now I can lower the rear subframe to get to everything. By the way...no evap codes. Our Snap On scanner said there was a small evap leak and said catalyst but I'm not sure what that means.
Sub. I really appreciate a knowing tech..even if different from my profession..it is logical to 1 diag with new data compare , if possible, to previous data. Double check other data repairs, then go on data set #2..seek and solve, check again. Hydraulics say 'when in doubt, meter out, Electricians say, ' don't let the smoke out' 24:22 Carpenters say ' be nice, measure twice,' Your field, auto mechanic, and mine hvac mechanic are the same..totally no call back or return. Thumbs up my new LOGI TECH. 👌👍
Hi Mike, great vid, one tip for you, universal fuel pump lock ring tools are quite cheap these days, saves using a hammer and chisel and the possibility of breaking components.
Of course this just popped up in my feed. I just authorized $1400 for an inherited 2004 Chevy Avalanche to drop the gas tank and replace that sensor, new charcoal canister and the purge sensor. I remember when I was young and had time to work on my own cars. Damn you responsibilities!! I hope I didn't get one pulled over on me.
Wow, good thing that customer found you, Mike! Imagine how many more parts they'd have tossed at it after the computer was installed! YIKES. Nice one - have a great weekend!
Thank you for this very useful video! I need to check your EVAP related playlist too. Yeah, I see people tend to replace everything all around when an issue happens, but finding the source of a problem is the key. And it could save you tons of money. It's sad the previous shop tried to rob the client just like that. Today I purchased a cheap smoke tester on Amazon and hopefully once I receive I'll be able to tell where is my car leaking gas vapor. It has P0455 error code. I have a vacuum pump and I checked both purge valves (this car has two) and they keep the vacuum or pressure pretty good, maybe there is a tiny leak there, but I'm not sure if it can be a reason for P0455 code. That's why I decided to check the system with the smoke tester. The car is 25 years old, so hooking a modern scan tool isn't an option. PS: It's interesting the smoke test didn't show the leak from the gas pump. I may be wrong, but I suppose maybe it's because the vapor dissolved when going through the tank full of gas (I suppose the EVAP lines are on the bottom of the tank just like on my car), thus the only way to check it was by using the old good soap test.
I agree with you! I went to kia dealer here at fort Pierce to install new HEU recall. When i brought the car, there was no issue, after that i drove a 16 miles and engine light check went on. When i was there, dealer was trying to sell me a car, dont know if the dealer is trying to sabotage my car so im forced to buy the car. Then i went online, the vehicle they're offering is listed $23700, but they gave me a written offer of $25895, which is over $2000. Im kind of furious with the dealer!
I changed my own evap, it wasnt easy but did it...cost under 250 for the charcoal canister....while at it i made other repairs like spark plugs , coils and gasket
Good job, I had a shop quote me $2500 for a bad ECM when the car still ran I decided to take it to the dealer and they found a bad pen ended up being 700 bucks
I think the previous shop broke the tank pressure sensor when they dropped the tank because they didn't unplug it. Once they lowered the tank and saw the pressure sensor dangling, they figured they found the problem. Shops like that, unfortunately, make it seem like they industry is plagued with shysters.
Hey Joseph, thanks for watching! That's a good theory and matches with the way the sensor broke...judging by the piece I found in the tank. It is unfortunate...ugh!!! Mike Becker, Senior Instructor
Very informative video. As a retired auto tech of 45 years I saw this problem more times then I can count. The broken piece in the tank was from the FPS being twisted sideways trying to get it out. The soapy water also worked good for locating evap leaks in the hoses running under the vehicle. A lot of times rust would cover up those leaks to even though the hoses were plastic a lot of times. Keep up the great work
Did the FPS break off from age embrittlement or not using the right technique to remove it? All the plastic cracking problems makes you wish for the old days of metal parts 😉
Nice job as always Mike. This happens in every country. I give my customers photos of everything I do to help explain why I have done it. If a tec isn't willing to do this be couscous.
Soapy water is part of EVAP leak testing 101, why do people not do this? Learned that in school 13 years ago and do it constantly while testing evap leaks. Super common on GMT-800 platform trucks that have steel fuel pumps, can't see smoke but sure can see bubbles.
You, my friend, are the type of mechanic that gives us all hope that honesty and knowledge of your craft still exists! Thank you for sharing this video.
The last shop was a remove & replace shop. Yours is a true diagnostic shop.👍👍👍👍👍
Hahah yeh, I guess so Waleye Fish. Thanks for watching!

I'm a retired technician. I've worked for dealerships and independents. I never hear mention of the service writer/manger miscommunication causing some of these customer problems. Usually service writers know little or nothing about cars. They are glorified salesmen! I've watched service writers call customers after I've given them a diagnosis, and tell the customer a completely different story! Be aware, not all comeback problems originate with the technician. 🚗
Hey Ed, could not agree with you more! So much can get lost in a lack of communication. Unfortunately it's not my shop, not my car, so I wasn't involved. I went off of the facts I had, previous invoices and a broken car. And of course the customers side of the story. But you're right. The shop or tech may not be at fault here.
Mike Becker, Senior Instructor
AGREED!!! So true!👍
Anon Ymous Used to see that all the time at my previous job. It was mainly one guy doing it and nobody could touch him. Management loved him, he was top 5 salesman in the country.
I work for hyundai and i see the same stuff you all said. They they sell a 30 or 60 service and then i present them with something else the customer needs and should be priority and they blow it off and make it as if the customer declined the work.
Absolutely! Also true for home repairs - especially appliances roof leaks and garage door problems
This is by far THE BEST EVAP TEST I have seen. Very complete and detailed. Covered every typical problem with no fluff. Great Job.
Wow thanks so much Derrick!

@@GoTechTraining I have a 2001 Ford E250. No code no check engine light, but will not pass the ready test. New gas cap, New hoses, valve seem to test ok. Any ideas?
This is how a professional mechanic works compared to the regular mechanics. That's why they charge more but actually get the job done. Great job!!!
I a not a certified mechanic... I try to use common sense when I work on my cars. As soon as you started the smoke test I was like "Make sure you test the part you bypassed!!!" Sure enough, you went back and tested it. YOU are a smart mechanic and use common sense. Customers would be wise to listen to your opinions and suggestions. Good job sir.
Hey Evilthx, thanks for watching! It's amazing the things you can do by just applying some common sense 😉
Mike Becker, Senior Instructor
If it were COMMON sense, most everybody would know what to do. It is indeed Uncommon sense that separates us
@@frnkjones40Im 16 trying to fix p0455 I bought a fog machine and cut a oil cone cup to attach it to and made my smoke machine. Replaced the cover centrifuge, purge valve, intake manifold, oil drip pan, cam plugs, re hosed vacume lines that were cracked, you are lazy and don’t want to see your car run, i will make my car run and refuse to pay someone to do something I can, anything Is possible be patient and research
Cant cross your fingers lol. Find your leak and show u can do it all, people won’t do work on my 2008 c300 and overcharge me because they think I have money. Poverty will drive any man to do anything. U got this

Lazy people don't drop and replace their transmission at midnight in the freezing cold by themselves because they need that car for work 6 hours later. They
The signal wire doesn’t send 5v to the sensor, the Vref does that, the Vref and signal are just shorted together inside the PCM for diagnostic purposes Chrysler does the same thing, while Ford and GM do not if you measure the signal wire in those cars it will read 0v. You had the right idea just explained it slightly wrong and it’s a pet peeve of mine... still love the videos and you’ve taught me a lot over the years!
You caught that too. The signal is the how the ECM interprets the sensors’s data which is the change of the 5vref.
This dude rocks!
Ive hardly ever seen someone with as much knowledge and professionalism as this guy has. Two thumbs up man. Keep the videos coming. U are a shining example for everyone who has to work on cars.
im giving you more than one thumbs up ,one for the purge solenoid ,fuel pressure, sensor, one for the cracked fuel pump,one for the tip about the rust causing pressure ,one more for mention the abs sensors affected by rust...I will like to subscribe again if I could ...I remember one of your videos showing how evap works...thats a big key how to diagnose this type of problems...thank you Mike...from phx az
Hey M Lez, thanks for watching! If only it worked that way, i'd take all the thumbs up you're willing to give.
Mike Becker, Senior Instructor
Every one uses a smoke machine for the smoke and its a great feature , but the little ball will tell the true story about evap leaks , if it doesn't drop to the bottom you have a leak! The soapy water is the way to go on hard to find leaks ! Great tips.
The fuel tank pressure sensor was broken at the time it was removed and replaced. It happens a lot if you are not carful when you remove an old sensor.
Great troubleshooting by taking the time to know how the EVAP system works and systematiclly isolating the problem to a physical crack and faulty component. This is what separates you from the rest. Nice job conveying the story.
You apparently haven't seen Eric O. videos or Rainman Rays?
Just subbed ... always refreshing to see a guy who not only is thorough and checks service manual/tips ... but also has good critical thinking skills .... evap systems are a pain ... and there is certainly simpler ways of achieving better rebreath of vapors ... but they don't call it the "Money Light" for nothing ...
Welcome to the channel :)
Mike Becker, Senior Instructor
Thank you for posting this to the public. You just gained a new follower, simply because you followed proper procedure. Not only that, but you show how much you genuinely care about your customer, and doing what’s best for them. Job well done, son.
Just want to say thank you for how thorough this video is. It helped me solve an evap code on a complete different vehicle. The hose connected to the bottom of the purge control valve had a sizable tear, not visable from the top of the engine bay. Followed your method of methodical visual inspection and immediately found the cause before throwing money at replacement sensors and parts!
Thanks!
Thank you you are the best. I really learned a lot
Rust jacking , technical term is "Oxide jacking" Great find ! Evasive and none evasive testing is always required, you are a credit to your trade Sir.
You made a believer out of me with one video. I do my own repairs as often as I can thanks to guys like you that teach me how. The best part of the video was knowing that you had the customer in mind. Too often people who do repairs (on all kinds of things, not just vehicles) have only their profit in mind.
Rust Jacking......WOW! What a great diagnostic case study....same as ABS sensor.
Well Done!
Mr. P
Holy cow batman, this customer was about to be in deep!!! Even deeper then they already are!!!Great job Mike!!!
Hey Mister Handy, for sure! I feel like we saved this one, pulled him from drowning in the deep end of the parts pool. haha!
Mike Becker, Senior Instructor
When pressure drops indicate a leak in areas you can't see to test with soapy water you can sometimes run your hand over the hoses and feel the leak. Or stethoscope the leak. Sometimes if you feed the smoke machine from the filler neck you may be able to see smoke that will not be visable after going thru the charcoal canister. You have a really technically literate following. I have to watch parts several times to absorb the information, the same with some of the comments. Not a criticism, but a compliment. I solved a witch of a problem P0455 with your assistance. Thanks.
Excellent video as usual my friend. Great way of breaking down the process. Highly recommend your EVAP videos to the younger techs coming into the shop who want to expand their knowledge and truly grasp how the system works.
Hey Steve, thank you so much! I really appreciate it 😀
Mike Becker, Senior Instructor
I can’t believe how many shops get this wrong! They should definitely watch your video series on EVAP,that way they will learn how easy it is when you know what you’re doing! 👍
Hey Nick, thanks for watching! There's so much misunderstanding around it...I think it scares some shops.
Mike Becker, Senior Instructor
Made my own smoker - found a smoke trail coming out the EVAP TEST PORT - used the Purge port
since the purge valve was tested - new - using the LASER Idea I noticed a hazing of the RED beam.
Fixed LARGE leak 455
Hi CJ,
Nice work! The red laser is a great tool for finding smoke!

The frustration level was pretty high Mike from your voice. Thanks for the education today, great job as always
Hey William, haha you could tell, huh? I'm just glad this one wasn't live...there were some cuts that had to be made 😂
Mike Becker, Senior Instructor
@@GoTechTraining No doubt!
Thank you I stopped calling myself a mechanic when all these electronics started to be added to vehicles and the diagnosis of them varies inconsistently. And the cost of the diagnostic tools were to much for me. As a parts changer now it's more frustrating to not look like I'm dragging the job on to make more money. That's why I love UA-cam and people like you to get right to the issues of these modern day overthought vehicles that come with parts that are designed to fail in shorter periods of time. As one mechanic once told me; they make more parts than cars
Thank you for taking the time to demonstrate how to apply basic fundamentals utilizing readably available resources to perform a successful diagnostic and repair.
The other lesson I took away from this is the importance of Integrity, Accountability, Transparency, Ethics…all of which appears to be at the root of why this particular car is in your shop.
Hi J P,

Good Presentation!
I just ordered a complete Fuel Pump Assembly, for my 2006 Hyundai Elantra HD.
I did smoke test fuel tank, with Smoke Test, without theVacumn gauge system.
There was no visual leakage around top plastic fuel pump assembly.
Anyway living remote I decided to replace complete Fuel Pump Assembly, just in case, either the Fuel Tank Pressure sensor is faulty or the plastic fractures around the lock ring on removal .
Hopefully my DTC and CEL, issue will resolve. I've replaced every other sensor, new fuel injectors, CVVT solenoid valve, Purge Valve, Throttle Body Assembly, because it failed smoke test(leakage from butterfly spindle shaft) , both sides. Excessive wear, made no difference. PCV valve, Rocker Cover Gasket, Vacumn lines engine through to purge valve.
The fuel pump seems to possibly be failing.
Put F-10 , fuel cleaner treatment through, still not cleared.
New Ignition Coil and Spark Plug Leads and Spark Plugs.
Hopefully the OEM fuel pump assembly will kill this CEL
I saw the rust on the fuel pump towards the beginning of the video and I knew we was in for sum trouble!
Hey J. M., thanks for watching!
Mike Becker, Senior Instructor
Great troubleshooting diagnosis. It’s almost never the ECU yet it always seems to get the blame. Some people are just really bad at troubleshooting!
Hey Mjg263, thanks for watching! It's the big mystery box...when all else fails..."it must be the PCM"! haha!
Mike Becker, Senior Instructor
Its that they dont know what they r doing
My question is how people can just part with so much money....and yet accept it with these faults.
Good work! Wish I could count on most shops to be as thorough. If you get incompotent mechanics, you can easily just get lots of tests and parts passed along to customer & still not fix the problem, which appears is what happened here. Good work, and I better understand how these systems work now. THANKS & it WAS a very good subject for a video. I'm sure the customer was feeling leary about yet more parts being needed when you first called, but everything you did was necessary and proven so, because it lead you to finding the problem and fixing it. And I'm sure your explanation would make sense to them , as it does when watching the video. If you are a DIY person, with no access to expensive code machines and access to manufacturer's information, you expect tht you might replace some things that are not needed, but you expect that when a garage is charging good money for hourly rate, etc. that those resources ARE BEING PUT TO WORK. I've recently bought a cheap code reader for about $25 along with my long time practice of having a REPAIR MANUAL for the cars I own. Together, these have been an invaluble tool for a DIY person, with a little info, it allows sensible checks, and spending a lot more on a more expensive tool isn't going to help me much, because I can't afford a bunch of speacialty tools & books, so would need a shop to do that anyways. And checking out some videos on my problem has been a nice addition from modern times, that often helps you know what to expect when taking things apart.
That 5 volt at the sensor wire when unplugged is the bias voltage the ecu uses to sense if there is a break in the wire or sensor. There is a relatively large resistor between the signal circuit and a 5 volt supply inside the ecu. There is normally a small current running through the signal wire when things are in order, and with current comes voltage drop. The voltage drop over the biasresistor makes the bias voltage magicaly "disapear" before the eyes of the "signal voltage reader" and it only sees the voltage from the sensor itself.
So the 5v on the signal wire isnt changing with pressure. Its voltage being dropped inside the sensor between the 5v ref and ground that is "fed" up the signal wire that the ECU senses.
So. If the ECU sees 5 volt at the signal wire it knows its either because there is a break in the circuit so that there is no current flowing, Or the sensor is broken (it never gives 5 volts out when its OK. Neither does it emit 0 volts. Its probably more in the range of 0.5 to 4.5v or there about)
Hey Steve, thanks for watching! Great explanation on how the circuit works. Thanks for sharing!
Mike Becker, Senior Instructor
Yes exactly!!
you deserve a mechanic purple heart award for this video .... been dealing with evap codes for years now bout time i dig deep and fix it thank you!

Hey J Georges, and thank you for taking the time to watch all of them!!!! :)

Great thorough diagnosis and explanation of how the system works . The visual and COMPLETE inspection of the SYSTEM is critical . We may not have the complete story , BUT if they researched , they would never of had to drop the tank . It seems they were quick to slam in parts without going in depth . What scares me is the ECM " diagnosis " . If that went in - then what ? How do they get away with it ? And now my lesson learned on from my old 1987 Celebrity , 2.8 L . It intermittently ran lousy . Vacuum dropped under 12 lbs . at idle . I ran tests on everything . Changed a fuel filter , which wasn't restricted . After studying the shop manual , I plugged the evap purge solenoid and drove it for days with no problems . The solenoid would stick open instead of being pulsed by the ECM . I don't know if over time and rough roads , RR tracks , etc. the charcoal gets pulverized and makes the valve stick or if it just wears out . I don't know if that would skew the fuel trim numbers when stuck open from the vacuum leak ?
Hey Bill, thanks for watching! You're right, the tank never should have come down. As for the purge solenoid being stuck open...the trims will depend on the saturation of the canister. Typically you'll see a lean condition. But rich conditions aren't unheard of.
Mike Becker, Senior Instructor
Grew video. I had an Elantra last week with a bad canister and after 2 shops misdiagnosed it I became the heroes.

Same here. I need someone to fix my vw golf !! Mine doesn't have a cel coming on or anything ! Idles really rough puffy idle. No smoke. Shakes the entire car and engine. Just lost at this point...
@Sam S I checked the to make sure the cel works and it does. Just hasn't been long enough or bad enough symptoms for it to kick the light on yet I guess.
I'm a tech at a Honda dealership. Honda had an issue with cracking fuel pump modules extremely similar to this. I've even seen it actively leaking fuel while running; interestingly enough, I don't recall it causing evap codes. Good find!
The soapy solution test was the key here. You can't rely on the visual smoke from the smoke machine for a small leak. I learned that here.
I have same car but v6. Same issue with purge solenoid and rusty fuel pump. Soap water and smoke machine saved me. Thanks for in depth video.
Hey David,
Nice work! Glad you got it fixed!

These things happen from time to time but the pcm being the culprit these dudes knew they were takin this guy/gal for a ride.
You really are a great teacher, Mike. No one has to tell u there are plenty of ethically-challenged mechanics waiting to take advantage of folks.
Hey Bgregg55, I absolutely hate that about this industry...well, I guess it's every industry...I guess I just hate it when people take advantage of people in general.

@@GoTechTraining yeah I work in computers and this happens in the IT industry too (though it's less common now the days of $1500 computers are over and everyone has a tablet now). The sad thing about our current society, is that I could be a lot better off financially had I decided to rip people off.
I know nothing about cars but always prefer to work on them myself, get info via youtube and forums, and also get my own codes. TBH Everyone who owns a car should buy an ODB2 dongle, they are very cheap. In the end a garage will probably end up doing the work but at least I'll be aware what the problem was in the first place.
Hey Mike, thanks for watching and commenting. You're right...in the world we live in the morally questionable people tend to excel. That sucks!

Sometimes on purge solenoids, I use a vacuum gauge on the end coming from the tank to see if there is vacuum coming out of the purge solenoid with the electrical connector disconnected and engine on.

I fixed mine PO455 code on my 08 1500 Silverado for under $40 just today. Took me less than 15 min to swap out a faulty evap purge Solenoid. Engine Light is out.

Hey Rich, thanks for watching!

There’s a a lot of parts changers out on the market that lack. Skills on diagnosing electrical issues. and a lot of customers have been screwed that’s why a lot of people are driving new cars they’ve been burned too many times you have a great diagnostic approach 👍
Hey O Rebelo, thanks for watching! That's very true.

2K??? I bypassed the charcoal canister. No engine light. Tuned it a week later just in case. Spent $325 on a BlackBear tune and bypassed with parts laying around the garage.
Great video to reinforce my next step. 2012 Silverado, P0455. I cleared the codes, replaced the purge and canister vent solenoids, but although I've driven a few hundred miles and have no CEL, I can still smell gas odor. It's very strong actually. Given it's a pickup and with no access hole to the top of the tank, I was hoping a couple $39 parts would do the trick. Nope. Now I face the dread of dropping the tank on this beast. At least it's off the ground. I expect the same finding - leaking at the access hole for the pump.
Hey Mike, sorry to hear the struggle that you have ahead of you. Hopefully you don't live in the rust belt like me! A word of advice...use as much gas out of the tank as possible. There's nothing worse than needing to drop a full tank of gas.
Mike Becker, Senior Instructor
Thank you so much in explaining the whole process on how to diagnose the EVAP system. I’ve been shotgunning parts left and right. I don’t have a smoke machine so I’m gonna just use a vape. It didn’t occur to me that new parts might case an issue also
An apple for the teacher on this one. Keeping an eye on that bubble was critical. I had a Dodge Caravan with a cracked fuel pump in good old California. No rust on the ring. Nudging that ring with the air hammer was also excellent!
Hey Bill, thanks for watching! The air hammer is just what I have to do since I don't have the special lock-ring tool. It works, right?

My son-and -law was very sure that the gas tank was leaking in his 2010 Hyundai Sonata. But now he is convinced that the gas pump might be the problem. The car has fail the state inspection twice, and the "permanent code" PO455 keeps showing up. We w'll see wat happens next. Thanks for your video,
I wish u were closer so I could get u to fix my truck! Took it to 3 people already n no luck I know u could do it quick. Wish more people were honest and as good as you..
One of the things I learned from Keith. Smoke is absorbed by the fuel. The more fuel in the tank, the less the chance of seeing smoke.
And the charcoal in the canister! 😉 Thanks for watching!
Mike Becker, Senior Instructor
@@GoTechTraining ah yes
I've had rust crack a toilet tank much like that. The studs that were built into the tank eventually got rotten from years of condensation and put enough pressure on the tank to split it quite a few inches. Two things to take away is rust can expand in all directions and rust can win at all the worst times.
Hey Shaun, so true! Rust almost always wins...unfortunately :(

Great job on this, in the case of these other mechs that checked this, they definitely were lacking the proper experience and just kept adding parts to see if the problem would go away or they could be one of those dishonest shops that keep the customer coming back for more which equals more dollars in their pockets.

LOL...That drawing at 13:40, Picasso would've been green with envy.
Great diag Mike. I bet you felt great when you found the actual problems that the other shops couldn't find, and I bet the customer felt even better. I had the same issue this summer on an 07 Mazda CX7. Plastic sending unit cracked and failed evap. New unit and seal but the locking ring went into the sandblasting cabinet and had a fluid film bath cause my customer couldn't wait a few days for a new ring. And now I know why they crack like that. Thanks Mike. BTW I conceded on the Focus for now. All out of ideas.
Hey Mike! Thanks for watching! Sandblasted and coated sounds like a perfect repair to me. My local dealer had one in stock..wonder why? ahah😉 Sorry to hear about the Focus...wish I had some other ideas for ya.
Mike Becker, Senior Instructor
Thanks for your ideas thus far Mike.
This morning I had a car that was overheating. Had a bad spring style hose clamp and lost a lot of coolant. All fixed now but before they brought it to me someone had told them it probably needs an O2 sensor. LMFAO!!!!!!! I bet you get those comments all of the time from customers.
Try changing the lines with just rubber hoses.
Mike, you did a hell of a job in your explanation of diagnosing this car. I really feel bad for the customer that spent $500 dollars with a vehicle that still wasn't fixed. And good of him to bring it to you in saving $1600 where it still wouldn't be fixed. Oh, I meant to send you an email about receiving the T-shirts and got side-tracked. Thanks Mike for the shirts and keep up the good work with the videos!
Hey Terry, thanks man!!! I felt so bad for this guy...and to spend $500 to "drop the tank and inspect" when the tank didn't even NEED to be dropped ARGHGHGG! ***Deep calm breaths*** haha! I hope you like the shirts! 😀

What was the final repair cost from your shop?
Too many shops do that, they see a code and start throwing parts at it. There is some intuition involved but these are computerized things we're dealing with, so you can't always be sure of a hunch like back in the day. The fact that they removed the exhaust and did so much unnecessary labor is a testament to their incompetence and ignorance. I hope the owner took the original shop to court.
Hey Jim, thanks for watching! I'm not sure what's happened since then...the customer was happy with me..not so happy with the previous shop.
Mike Becker, Senior Instructor
Man, I would LOVE to work in a quiet shop like that for EVAP leaks:) Nice work bro! You are a professional and you take all your training and experience serious, that's great! You have the right to get upset when a vehicle comes in like this! I assure you, your not the only tech seeing this.
There are waaaay to many shops that have no clue on what there doing! Is this okay? Who/where are the people in charge that make the decisions on who needs licensing in the trades? You need a license to cut hair here in MA. Do you think auto shops should be licensed? I think it would weed out the problems immensely! It also may give Mechanics/techs the respect/credit they are due when they put so much into being the best they can! I put my life into this trade! Though, If I could start over. I would have chosen to become an Electrician, Plumber, or even a Carpenter. Far less tooling, more respect, less training, and most get paid more per Hr starting out then a master mechanic does 30 years in.
example of what should be done: you want to be a Autotech? Okay, set up a shop with 3 or 4 broken vehicles in it(electrical & driveability). Have the license goer fix each one on a time limit. give the tools(scan tool, M-meter) service info, repair order concerns. Make the diagnosis and report your steps.
What about ASE you may ask? ASE is a joke! most shops have the signs up for ASE but have like 1 certification, maybe. You never see those guys(from the "shops") at any training venues! What do you think should be done about this HUGE problem in our industry?
then there is You-are-a-mechanicTube :)
holy moly.. a bit of ramblin today..
Okay, I'm done:)
A rating app will give power to the customer.
This is what i called ASE technician like you mike i trust ASE technicians without a doubt cos why you guys knows what you saying and what you doing in the shops i only goes to auto shops when there's a lotta ASE technician on duty...lol... there's a lotta mechanics out there who really don't know the basics how to fix the problem so today i was at the smog shop to smog my 1990 mazda truck b2200 series 2.2 liter cubic engine it has 143, 000 k miles but didn't pass the smog the fuel evaporative controls functional failed i look the fuel cap is brand new the original owner replaced fuel cap so to make sure there's no faulty smokes coming out from the fuel cap and there's no fuel smells under the hood or anywhere so i was wondering what seems to be the problem when the fuel evaporative controls functional failed mike on my vehicle i work on my car and truck sometimes when minor repairs need to be fix but I'm not an ASE like you are sir.
My employer asked me how to find better industrial mechanics. That's a good question. Frankly could be several ways.
BUT. Change the question. What does a master industrial mechanic look like???

The benzophenes and sulfur released from the metal during oxidation causes the polyethylene to become more susceptible to .. well.... let's say becoming brittle . Tank and the pump itself are plastic and will expand and contract of course. This movement causes these highly susceptible areas to crack over time. Now that I got that researched , I will say that was an awesome video bud. And thank you for making me read more than I ever wanted to .
Hahahahah so you're saying, in short, that my video made you a better person? 😆 Thanks for watching dude! Miss you and everyone else. Online VISION KC just won't be as fun.

Great help with my evac problem. Checking out top side valve first. Thanks
Thanks Edward! Good luck with the diagnosis!

I really enjoyed the diagnostics, problem solving, and truly excellent presentation skills. Doing IT for 30 years I can really appreciate a mechanic's skill and it seems a lot more interesting than IT. I just started a job and the work vehicle I have is a Toyota Rav 4 that came with a check engine light, VCS light, and 4WD light on. I couldn't get them to take it in so I put on my cheap OBDII adapter and phone app to get any codes, which was 5. I passed on the codes to the shop next time it went in. It been in 4 times and still hasn't been fixed. Winter is hear and I really want to use the 4WD. I wouldn't be allowed and don't have the skills to fix it myself but I really would like to know what exactly is being done over these visits. If I really needed to use the 4WD my guess would be I could clear the codes and use it until I get them again. Bad idea?
Excellent work 🤯 who would’ve thought it was a leak 🤨
Hey Hektor, thanks for watching man! All else fails...must be the PCM causing the leak 😂
Thanks for the comprehensive explanation. I gotta c230K 2003 that was in the shop for a p0442 400 miles ago...
I bet drinking a couple of tall stouts after that repair was well deserved and relaxing. I thought I was watching a magic show with all that stuff you were popping out from behind the cart. Ta-da! Car fixed.
Hey Glen, hahah yeh for sure! Cold and refreshing! I need to get one of those hats, I can pull parts out of it!

I disagree, it seems that allot of problems start with the service writer or the boss and last we also have lazy mechanics that only worry about making that check. I don't know, maybe these guys spend to much time on the S-O Truck LOL
My 96 Explorer had a p0455, It also had a smell of gas. The steel evap line in the frame had all rust holes in it. I replaced it with 13' of rubber 7/16 gas line and some wire loom to protect. Even though 96 is obd -II, it did not show a CEL for that code. In that year for evap it just records a code internally and leaves the monitor unset. I also disconnected the FPS and just got a code. You could pass in NY with 2 unset monitors pre-99.
Hey, thanks for watching! Interesting how the check engine light wasn't on! I think it's the same by us here in WI. 2 unset pre-99'.
Mike Becker, Senior Instructor
@@GoTechTraining I did some research and Ford disabled the leak check for almost all 96 cars (hardware is there, but it isn't in the calibration). So no CEL. www.fordservicecontent.com/ford_content/catalog/motorcraft/obdsm963.pdf pg 15. There is good free reference there for diagonstic stuff!
Got to love evap testing. You made evap testing easy bud
Hey man, it's easy when they have a panel in the trunk!! 😂

Lexus dealer told me to replace fuel injectors for cost of $2300 to fix CEL. I asked for guarantee that it will fix and was told no.
So drove back. Then bought OBD2 scanner for $99. Got P0983 code. So changed solenoid S4 myself (kudos to UA-cam experts like you) and it’s been running for 18 months so far without any issues.
I don’t think mechanics at dealership are experienced mechanics. They may be trained but may be lacking experience needed for a good diagnosis.
Thank you for the very informative video! I am in the process of trying to find a small evap leak in my Pontiac G8 with the 3.6 V6. I'm attempting to diagnose and fix this myself because I know this very same thing will happen if I take it to the dealership. Happened to a guy I know at the tune of 2200 dollars. I am a heavy suspension mechanic so I have a lift to use at our shop and pretty much anything else I need(such as a smoke machine). Unfortunately, I am NOT a driveability tech so I have no clue of what I'm doing. I have to fix the small evap leak before I can fix a PO135 and PO154 code I recently got after my tuner turned off the P2190 code I couldn't diagnose(running rich). It's a mess and I'm foolishly throwing parts at it trying to fix it all. I have a new gas cap, purge valve solenoid, vent valve solenoid, fuel tank pressure sensor and vapor canister for it. This video showed me a few things I didn't know that should help. I can test the purge with a vacuum gauge and smoke test the system now thanks to this video! Wish me luck. I'm going to need it. Car is on the hoist, exhaust, subframe connectors, driveshaft and rear end is out and now I can lower the rear subframe to get to everything. By the way...no evap codes. Our Snap On scanner said there was a small evap leak and said catalyst but I'm not sure what that means.
Sub. I really appreciate a knowing tech..even if different from my profession..it is logical to 1 diag with new data compare , if possible, to previous data. Double check other data repairs, then go on data set #2..seek and solve, check again.
Hydraulics say 'when in doubt, meter out,
Electricians say, ' don't let the smoke out' 24:22
Carpenters say ' be nice, measure twice,'
Your field, auto mechanic, and mine hvac mechanic are the same..totally no call back or return. Thumbs up my new LOGI TECH. 👌👍
👍 you're the man Mike!
Shame on all you dishonest service people who intentionally milk customers instead of doing the right thing.
Hey James, thanks for watching! Yeh, a few bad apples can really hurt the name for technicians.

Hi Mike, great vid, one tip for you, universal fuel pump lock ring tools are quite cheap these days, saves using a hammer and chisel and the possibility of breaking components.
Hey Jake, that is so true! I need to buy one. Thanks for watching!
Mike Becker, Senior Instructor
Of course this just popped up in my feed. I just authorized $1400 for an inherited 2004 Chevy Avalanche to drop the gas tank and replace that sensor, new charcoal canister and the purge sensor. I remember when I was young and had time to work on my own cars. Damn you responsibilities!! I hope I didn't get one pulled over on me.
Wow, good thing that customer found you, Mike! Imagine how many more parts they'd have tossed at it after the computer was installed! YIKES. Nice one - have a great weekend!
Hey Smitty, sometimes it just works out, right?! You have a good weekend too!
Mike Becker, Senior Instructor
Thank you for this very useful video! I need to check your EVAP related playlist too. Yeah, I see people tend to replace everything all around when an issue happens, but finding the source of a problem is the key. And it could save you tons of money. It's sad the previous shop tried to rob the client just like that. Today I purchased a cheap smoke tester on Amazon and hopefully once I receive I'll be able to tell where is my car leaking gas vapor. It has P0455 error code. I have a vacuum pump and I checked both purge valves (this car has two) and they keep the vacuum or pressure pretty good, maybe there is a tiny leak there, but I'm not sure if it can be a reason for P0455 code. That's why I decided to check the system with the smoke tester. The car is 25 years old, so hooking a modern scan tool isn't an option. PS: It's interesting the smoke test didn't show the leak from the gas pump. I may be wrong, but I suppose maybe it's because the vapor dissolved when going through the tank full of gas (I suppose the EVAP lines are on the bottom of the tank just like on my car), thus the only way to check it was by using the old good soap test.
HI Тачкин,
Good luck on your smoke testing!
Thanks for checking out the video!

I agree with you! I went to kia dealer here at fort Pierce to install new HEU recall. When i brought the car, there was no issue, after that i drove a 16 miles and engine light check went on. When i was there, dealer was trying to sell me a car, dont know if the dealer is trying to sabotage my car so im forced to buy the car. Then i went online, the vehicle they're offering is listed $23700, but they gave me a written offer of $25895, which is over $2000. Im kind of furious with the dealer!
Very cool. Excellent diagnostic and repair confirmation with strategy based diagnostics. Too few take the time. Speaking as a retired tech.
I changed my own evap, it wasnt easy but did it...cost under 250 for the charcoal canister....while at it i made other repairs like spark plugs , coils and gasket
That's awesome Kas! Thanks for watching.

By far the best repair video i have ever seen. Definitely subscribing.
Wow, thank you so muh!!!
Mike Becker, Senior Instructor
Good job, I had a shop quote me $2500 for a bad ECM when the car still ran I decided to take it to the dealer and they found a bad pen ended up being 700 bucks
I think the previous shop broke the tank pressure sensor when they dropped the tank because they didn't unplug it. Once they lowered the tank and saw the pressure sensor dangling, they figured they found the problem. Shops like that, unfortunately, make it seem like they industry is plagued with shysters.
Hey Joseph, thanks for watching! That's a good theory and matches with the way the sensor broke...judging by the piece I found in the tank. It is unfortunate...ugh!!!
Mike Becker, Senior Instructor
true
That's why I go to the smoke test first for the 455 and it makes the leak far quicker to find, cuts down on labor and cost.
Very informative video. As a retired auto tech of 45 years I saw this problem more times then I can count. The broken piece in the tank was from the FPS being twisted sideways trying to get it out. The soapy water also worked good for locating evap leaks in the hoses running under the vehicle. A lot of times rust would cover up those leaks to even though the hoses were plastic a lot of times. Keep up the great work
Did the FPS break off from age embrittlement or not using the right technique to remove it? All the plastic cracking problems makes you wish for the old days of metal parts 😉
Nice job as always Mike. This happens in every country. I give my customers photos of everything I do to help explain why I have done it. If a tec isn't willing to do this be couscous.
Hey D. D, thanks!!! For sure, if they aren't willing to show you...they are likely have something to hide.

the auto diag is fantastic but the video quality is right there too. channels like this are the reason YT is killing TV.
WOW halleffect1, thank you so much for this comment. Really appreciate it!!!
Mike Becker, Senior Instructor
My 99 Cherokee is nimble and mostly avoids the parts canon. Even with it's no code misfire that no one can diagnose.
Soapy water is part of EVAP leak testing 101, why do people not do this? Learned that in school 13 years ago and do it constantly while testing evap leaks. Super common on GMT-800 platform trucks that have steel fuel pumps, can't see smoke but sure can see bubbles.
