Multiple Evap codes and more please help

[Isaias]

Check engine vac and trac light on. I replaced the gas cap about 8 months ago. I have lots of obd codes showing

code c1201p0455 p0456 p0441

The gas cap replacement has fixed the problem before. Now I'm concerned it may be something else. Before I drop another $30on a gas cap I wanted to see what other problems may be happening. I've also tried to wd40 the ring on the gas cap. When this started last week it kicked out some other codes
C1241 c1223 c0215 but those have went away.
So far I've read charcoal canister purge valve gas cap. I'm not exactly sure how to check the valve under the hood. Can I just take it off and blow it it? Does it need to be vacuumed if I put it back? Will happen if I take off the hoses and remove the canister? I don't want to cause damage I'm really tight on money right now and looking to do the replacements if needed by myself. I've read other forums but none really mention multiple codes. Are there vacuum hoses that may have come off? If so I'm having no luck on finding the actual pictures that show me locations for 2007.
Today after work I went to start my car and it didn't start the first time. It sounded like it was gonna start but didn't turn over. I want to say it was related to the issue I'm having cause I've NEVER had a problem like this before

I think you need a charcoal canister.

Good thread here discussing this problem , and how to test for leaks in the system : http://www.toyota-4runner.org/4th-gen-t4rs/223147-code-p0456-when-its-not-gas-cap.html

I think I'm gonna try to get in for a diag to try to pin point the problem. I don't want to goof anything else up. I've never messed with the evap/fuel stuff

I had the same codes you did. Turned out to be just the cheap VSV under the hood and a gas cap. In total it was a $50 fix. The VSV can be had on Amazon for 25 bucks and a new gas cap costs ~20.

 

[Isaias]

Did you need any special tools?

 

[duffdog]

just a 12mm wrench, nothing else.

So

Is this it here?

Yes, that's the part in question, AKA "90910-AC001"

Amazon insists that these alternatives wont' fit a '2007 4runner sport v6'. If I made a photo, it would be identical to yours - including the unused horizontal "tab with mounting hole". But this is the OEM part on my V6 4Runner sport 2007 - the same machine as car as yours (except for the color, and maybe the stereo). :hatsoff:

Here's the OEM: https://www.amazon.com/TOYOTA-VACUUM-4RUNNER-CRUISER-90910-12262/dp/B016FFP936

And here's a cheaper Amazon "Clone" which also looks like the right thing: https://www.amazon.com/EXKOW-Solenoid-90910-12262-136200-2911-FORTUNER/dp/B06ZYB4DZQ

The also have a" Wells" product, but it costs nearly as much as the OEM. The replacement Toyota part is almost identical, and also works:
"90910-AC001 - Vacuum Valve. ... Manufacturer: Toyota; Part: Vacuum Valve; Replaces: 90910-12262" Most Internet sellers have the new one, rather than the old one.

New edit on 4/13: Over lunch hour, I just replaced the part on mine. I also noticed that Toyota did not put a clamp on one of the connected hoses (the long one, into the engine). My hose came off from the old VSV pretty easily, maybe a bit too easily. And so, along with the new VSV, I added clamps to hold the ends of the engine-side hose tighter. I cleared my codes, and I'll drive the car back to work. We'll see if the codes come back overnight.

New edit 4/14: Codes have not come back after an overnight "rest" (allowing the tests to be re-done), and after a couple of short drives. I created a new Thread, highlighting the cods I experienced - to make it easy for others to "match" when searching the forum: http://www.toyota-4runner.org/4th-gen-t4rs/254135-another-possible-cheap-fix-fix-codes-p0441-p055-p056.html

Awesome!! Thank you!

 

[Isaias]

Btw what kind of stereo do you have? I have the stock with navigation. I want to upgrade but haven't gotten that far yet.

 

[Isaias]

So it's been working?

Is this it here?

This solenoid was clacking loudly. I put a clamp on the output side that leads to the intake. The clacking stopped and no more check light.
