'11 GMC Sierra - Engine Light With EVAP Codes

[@TStheDeplorable]

Just yesterday I was working on my neighbor's truck and I hit a milestone! He wanted a tune up because his truck idled rough. I put it on the scan tool and determined that the MAF sensor numbers didn't look right, and the fuel trims were too far into the negative. I cleaned the MAF sensor and very soon after that the truck idled smoothly. I told him he didn't need a tune up. This means I am officially "not just a part changer!" I owe it to several KZbin mechanics, but mostly you! I've been watching at least 7 years.

[@jamesbizelli8568]

Good for you it’s always rewarding when you can put knowledge to work and be self reliant. I owe Eric and others the same respect

[@major__kong]

My truck just threw a p166a after sitting in an airport parking lot for 3 days. I carry a OBDII dongle with me, and it didn't show any codes even though the (Ford ) "wrench" light was on. I got home about 1 in the morning and threw my Thinktool Pros on it. Nothing showed in the topology, but the code came up in the report. Interweb descriptions of the wrench light don't seem to line up with the code description. And the code description is clearly a circuit problem but it's throwing a P code. Guess what I'm doing this weekend? God I hope the connector isn't buried.

[@johnevans9751]

If I had a million dollars every time I had to clean a sensor on my 99 MX-5 (NY emissions setup) I'd be a multi-millionaire.

[@TStheDeplorable]

@@major__kong Good luck! I hope there's an obvious break for you to easily find and fix!

[@WTFIsThisGuyDoing233]

The most amazing part is cleaning the MAF actually fixing something

[@DDescalchuk57]

That intern has no idea the gift he’s been given being able to come in green and be taught by one of the greatest mechanics alive. I’m a full time tech for the last decade and in the last 4-5 years watching all of your videos I’ve come so far and improved drastically. Watching your ways and implementing your methods into my day to day life has done a lot for me. You’re electrical diag 👌🏿👌🏿👌🏿 Seeing how your brain works in thinking about a feasible process is top notch. I’m lucky enough to still posses the drive and desire to continue learning unlike so many others in our trade. I’ve learned more in the last 4 years from you then I had working under journeymen while doing my 4 year apprenticeship. You keep up the amazing work man!

[@drloch6174]

Another positive about a green tech. They haven't developed any bad habits yet.

[@DDescalchuk57]

@@drloch6174 a green apprentice is one that’s most desirable to me personally. They have no bad habits and can be taught to do it how you want it done so once they become competent you can go on a holiday knowing that the work at your shop is being done how you want it done and can trust the employee you have

[@steveschaff8848]

It's great that you share your knowledge not only with us but also with kids looking for careers

Oh man you had me spitting coffee with that spray foam frame repair. It’s sad but true.

You're doing a good job with McCoy, it's hard to teach someone when you are used to doing things a certain way, and you have to remember to slow down and explain what you are doing and why.

[@RenegadesGarage]

South Main Auto.. That young man is getting taught by one the best. Just like I was taught many many years ago. That's why I always try to help/teach the new guys when they need help. Us old school guys should always be willing to teach our knowledge to others because when we die off the knowledge does too.

[@redlock4004]

The full circle. Just as Eric was taught by a master when he was young, McCoy is being taught by Eric, the new master.

[@MrTonyPiscatelle]

Good to see a young person wanting to learn your trade . Learn him good Mr.O

[@The_Redkween]

So nice of Eric to take time and show a youngster the profession and what it takes to be profitable. We will run out of mechanics at the rate we are going so this is great to see.

Excellent for bodywork also. Take your time and you might even forget about the gaping rust holes yourself.

[@morrisnewhouse7400]

Awesome! as a retired power plant operator, trying to train the younger guys to take over was painful for me. Hard to explain experience...

[@tonysikich4383]

Not too many folks take on someone like you did. I hope McCoy likes the trade and keeps going!!

[@spelunkerd]

The first few times I jumped a circuit with a test light and didn't get it to light even though I knew current was flowing, like here, I scratched my head. Of course the light has a threshold that has to be met before the light will glow. In this case, it's not just the fact that only 5 volts are available. These systems use a moderate size downstream resistor inside the PCM to create a voltage divider circuit. That allows easy measurement of voltage and also it protects the PCM and 5V supply by limiting maximum current. The resistor is so much larger than the test light, all the drop is eaten up by that resistor, so with current flowing there isn't enough of a voltage drop across the test light to make it light. Putting it another way, with all that resistance in the circuit the test light doesn't have enough current flowing through its filament to make the light glow.

[@karencary3312]

Thank you for investing time with McCoy. He is our future. ❤❤❤❤

[@KevinBarton-ow6ut]

Glad to see you are teaching someone the trade

[@gregsidel3557]

Eric, you're doing an excellent job. Teaching that young man that it's always best to go through each test. No matter how simple it might be, go through the test. Keeps you sharp on what's going on. In case you're running to something, it's real stupid which you have before. They would throw a normal Tech off. And then since you went through the test. Test by test, it keeps you sharp on what you're doing. Good job your boy will learn from the best

[@ordinaryjoe2247]

WAY TO GO!! ... directing McCoy toward Paul Danner's content. You'll be sitting in the front office with your feet on the desk in no time, while the student is out in the shop having surpassed the master. (Then, I'm sure, Mrs. O will be pushing you back out of the office to go do something because she's trying to get work done.)

[@tedbiernacki376]

McCoy has an up hill battle ! The amount of experience in Eric O's head is impressive! Vast library of knowledge under that Gulf hat ! 😊😊

[@subatomicparticle6535]

I also had P0446 on my 05’ GMC Sierra with the medium 4.8L and extremely low mileage. It was the fuel tank psi sensor and was able to reach in the wheel well over the frame rail with the wheel removed without dropping the tank and swap the sensor out and that fixed the problem. But before I did that removed the vent valve believing it was that just to find no issues applying voltage to the connector and the old breath test. That taught me like this good video that one code can set another code and once you fix the problem all the codes magically will disappear.

[@crashcreeley]

My boy McCoy... Well done sir... what a fortunate young man...

[@thelongs5698]

I believe McCoy needs an SMA sweatshirt to fit right in Mr. O, glad to see him learning lots of good stuff.

Yeah an US Flag after that. Because nobody nowhere else in the world wants to work. That's an uniquely American trait!🙄.

[@titaniumman_22]

@@horrovac I don’t really know the point of your comment. Anyway, I place an American flag after every comment I leave anywhere. It is a problem in the US with a lot of young people not wanting to work or if they work, it’s a sad attempt. I ran 2 construction companies and started having a hard time hiring young guys who ‘want’ to work. 🇺🇸

[@horrovac]

@@titaniumman_22 Instead of wondering what the point of my comment is, I'd like to suggest you should rather wonder about the point of you posting an American flag after every comment you leave anywhere... for what reason exactly? What is that supposed to tell us? Would the message of your contribution be diminished without you posting your national flag along with it? What does posting a national flag mean anyway? Would you find it easier to understand what the point of my comment was, if I had posted my national flag along with it? The point of my comment, I'd like to think, is clear enough based on my comment itself. You compliment someone wanting to work, compliment them on the job well done, and post your national flag along with it. That implies that you consider the identity associated with that flag with hard work and jobs well done. The point of my comment is that that's bullshit. Self-indulgent bullshit at that. Complimenting hard work and a job well done is something I'd be on board with. But then you choose to gratuitously exclude the rest of the world from that. Why?

[@imheck]

Thanks for training McCoy! I know it can be frustrating still you train us "SMA Tubers" everyday but we can be at a loss not being able to question "The Amazing Eric O" eventually it will be second nature. Some one told me; ""The best way to keep knowledge is to give it away"". That way your mind is working through all the scenarios. Many is the time I woke up & said I should have told him that so I went over it with them again. at least he's not looking at his phone like 80% of the folks I trained

[@gadasavideos8564]

Based on a previous video by Eric and some others I asked my mechanic to check voltage on my s10 sensor because I had p0446. It was hovering in 4.86 range. I decided to lift my box to check condition and rust paint underneath and replaced sensor with oem. Was able to back probe and confirm 1.5 v. P0446 is history.

Always good to have an SMA video waiting to be watched right after dinner.....Coney with mustard and onions, chips, and a coke btw.

[@bodynfocus]

McCoy's back! Fantastic.. ❤

[@1973retrorabbit]

As a sparky, I enjoy training apprentices, as long as they're willing to work and learn. Your boy McCoy seems to be absorbing the information... I learned, largely self taught from Haynes manuals, and trial and error, on older cars, with a lot less computers and scanners. Colour tune and timing lights, normal test equipment, meters and test lights, were pretty much all I needed. I guess, what I'm trying to say, is there's a lot to learn in car diagnosis and repair these days. There's a lot of expensive diagnostic equipment you need to do the job, unless you're a parts cannon moron, with more money than sense (for a DIY guy). Sadly, a lot of shops give your trade a bad name, using that tactic too... It's the same in most, if not all, trades. There's some shocking sparks out there. Teaching an apprentice how to use the tools of the trade, and how to solve the puzzles presented, step by step, is the right thing to do, and like you said, helps the ol' brain to retain the information yourself too. Keep up the good work.

I've been working in independent shops for 28+ yrs and the best thing that ever happened to me was finding a shop that took my book smart but experience 'dumb' 20 yr old self under their wing. I personally know 25yr dealer techs that have specialized in 1 system, that have never done a timing chain on ANYTHING etc, or that have never worked on anything other than whatever that dealership brand is. IMHO, good independent techs are the cream of the crop. Thx for all you do Eric!

Some years ago in Ontario the -drive clean- program was created. This meant cars had to be assessed every couple of years. Participating garages would run your car on rollers and measure various pollutants like NO, CO ... this involved a big investment for shops and a pain in the neck for drivers needing to make appointments. Eventually this approach was abandoned as the province realized that ODB systems were plenty good at monitoring defects. Now no inspections unless the title to the car changes. In that case a thorough go over is needed - everything related to clean running and safety. Holes anywhere in the body or frame or suspension is a fail. Still wonder what the shops did with all those service bays filled up with a dyno?
