Chevy Traverse: P0496 EVAP Code

In this video I have a look at a 2017 Chevrolet Traverse that came in with a code P0496 (evaporative emission system high purge flow) This is a pretty straight forward diagnosis and the good news is GM has an extended warranty campaign on these vehicles and you could possibly have it fixed for free. -Enjoy!

There's always someone bigger, better badder I suppose. I appreciate your humility. But I think your pretty hard to beat. You have an analytical mind and a can-do attitude and common sense. And common sense isn't very common these days. Plus you seem to be a nice guy with a good sense of humor. And you're honest, particular, and generous. I wish I could take my vehicles to you when it's stuff beyond my ability and tool depth. But I'm in Nebraska so my vehicles wouldn't make it that far even without mechanical problems! I enjoy you videos. Thanks for doing them.

[@yepper1165]

@David Lewis I do remodeling and handyman work. I've also been doing more air conditioning work on phones with my friend who's been training me for several years now. Figuring stuff out is a large part of my life. I do all right but I know there are people like Eric and my friend who make me feel pretty stupid sometimes! Gotta admire a good brain. Btw, I only work on my car. And tg hats out of necessity as I can't usually afford the shop rates. But I will not open up an engine. I know my limitations.

[@yepper1165]

@David Lewis It's interesting that there is a crossover from Eric's field to yours and to mine. And no doubt to many others too. A common ground that many of us who watch him work can identify with although we have different occupations. Figuring stuff out is built into us I think. The Bible says that we're made in God's image so I guess it makes sense that we are naturally bent toward troubleshooting/figuring stuff out. Unfortunately I think the modern trend toward many being lazy both physically and mentally makes a lot of people give up and lose interest before they tackle trying to solve the problems they encounter in their work. Sounds like you are not one of the lazy ones. That's great. There's a great deal of satisfaction in figuring things out, as you know. Keep up the good work!

Every time I see a NAPA commercial I say to myself, "Not a sponsor". It's all your fault.

[@bertgrau9246]

I bought a set of Accel plug wires from Napa on the box it said less than 500 ohms per foot, when I got them home I checked them. They were closer to 1500 ohms per foot. I took them back and told the counter guy what the problem was. He told me the ohms would be less in a race engine application. I was surprised he said something so stupid. I got my money back and went to AutoZone and bought the cheapest they had only 200ohms per foot!

[@stephenbay9564]

@@tomd5010 They had cylinder walls impregnated with 17% silicone.....the last step was an etching process that had the rings riding on a "wall of stone". I owned two. Rebuilt both with steel inserts. Bought the cars dirt cheap cause they was SHOT. My FAVORITE find about them was at a local machine shop. He had Vega blocks all over the place. He was contracted by the local Chevy dealer to fix them. And I noticed that a number of them that were ready to return to the dealer only had ONE insert in them. He said to me ....in so many words.....THAT GM WAS SOOOOOO CHEAP (HOW CHEAP?) THAT THEY WOULD ONLY PAY TO HAVE THE CYLINDERS THAT SHOWED SIGNS OF WEAR, BE SLEEVED!!! They removed the engine from the vehicle, sent it to him, and then with it down to a bare block, would only pay him to sleeve ONE cylinder. It was around 1975. I paid that guy $150 to machine the block, insert 4 new sleeves, and he handed me new rings for the pistons. Engine ran forever and never burned a drop of oil with the sleeves. Yes, I learned a lot about GM from that.

Good Vidio, Eric. , I try to explain that a trouble code only points you in a direction to get started

I have worked on automobiles doing drivability since 1987. I can count the number of gascaps I changed that were the prob on one hand and O2 has not been a major issue since 90's still some failures. It is the job of that scan tool "specially designed" and the sales man at auto zone and advance to sell you parts not diagnose or fix the car. And they are intentionally not taught diagnostic procedure on purpose. A part swapper trying to save money can spend more money if they dont actually know whats wrong :). BTW most stealerships hire part swappers to follow TSb's and not an actual diagnostician.

My 2002 Camry had an evap code. Watched all these videos about dropping the gas tank to fix it (something I'm not skilled/equipped enough to do and the car's not worth it to pay to get it done).
