Very good video all around Hector. Well explained.
You are absolutely correct that with proper info plus understanding how a system operates you can fix it. You just provided that info.
To find service documents can be a challenge.
Thanks a bunch for taking the time to video and edit so nicely.

Great video, you should be an auto mechanic teacher.

Thank you for supplying additional information than the others. I have the Topdon Artidiag 500s, almost the same. Now I should be able to fix my problem. I replaced both valves but not getting the command for valves.

Amazing video. Extremely well explained and visually documented. Best part, this was my very issue on my 99 LS1 SS.

Getting P0455 on 2017 Camry and tried to keep up with this, to mixed reviews. In the end it just made me realize when the bill seems high there's a good reason normally. I can handle checking the gas cap but iffy beyond that.

good detailed video! keep doing what ur doing. thanks for info and knowledge

I know that he said simple check, but at the end he leaves this video without an actual fix. It's obvious that p0455 can be any of the things that Hector mentioned, but it also shows that it can be another part of the fuel system. It could be the evap canister, it can be a hard line, it could be a soft line aka rubber hose. It also could be a simple gas cap or it could also be a bad tank. You should also check all your fuses and more possibilities.

Another great video for me!, nice work

At 7:15 when you switch your test light to battery positive to check command from computer to the purge, did you also switch the back probe to the orange wire?

Honey,
We really like your videos, very clear and patient. I was wondering if you would be interested in taking a video of our inflatable paint booth. Free for you to use our upgraded inflatable spray tent, even indoors, the double-layer EPA-certified filter cotton and the elephant nose filter system can achieve a good filtering effect. Please reply me if you are interested. thanks

Looks like the large leak was fixed by the purve valve...so the vacuum drop doesn't seem too bad...may not even throw a code...or will it? Seems the problem wasn't fixed? Fuel sensor?
