Fixing a P0449 code on a Chevy Impala 

Your last words on this video save my life cuz I changed the whole thing and the light was still on, now I just have to reset it 😎🤙

Thank you. I replaced my purge valve which did not solve my P0455 problem. Replaced the vent solenoid and canister, the P0455 went away but a P0449 came in. I fiddled with the electrical connection and a few days later after doing nothing else the code/engine light cleared itself. Sometimes waiting has an effect. It might re-learn something or the connector jogged into place while driving. I bought the vent canister with an adaptor for the electrical connection and a new hose and a new metal mount. All good investments. The hose going to the gas tank just pulls out with some assistance with a screw driver. The old vent canister had 5 places where it was in-leaking (same locations as you showed), and the valve was failed open anyway (particulate jammed it). A gasoline smell went away after replacing it and the vehicle accelerated more quickly almost immediately. If you replace a part, and its not the part needing replaced, just leave it because you are ahead of the component failure curve. Waiting a few days might fix your code for the non-serious ones like this.

You’re a lifesaver!!!!!! I just bought an 08 Chevy Impala and was so worried it would be an insane part to replace, you just proved it won’t be that difficult. THANK YOU!!

Terrific video. I love it when the complete process, including testing, is shown start to finish and this video does exactly that. Nice job!!

excellent,efficient diagnostic process! And I like how you stressed testing the circuit with a load, I do the same with my apprentices.

👍🏼 I like your tutorial, thanks. and thanks for the links for the tools used 🤩

I'm changing mine now and this is great,don't have a tester but I'm hoping this will fix.my problem, ty

Awesome video! Love the humor along the way, thanks.

Awesome video, can't get any easier to diagnose and check for power and ground . Thanks. P.s. hello from Connecticut

I have been watching your vids. And learning a lot. Thank u!!

Great job I really liked that you stated you cut the tube to make it easier. The bolt is a 6 mm bolt that has a 10 mm head. But very nice video.

Awesome video

I really appreciate that your words are directly related to the purpose of the video. So many guys have way too much irrelevant chatter. I have an 08 Impala with that code. I learned something but I think I got some dirt in my eyes. Just joking. Thank you.

Could you have just supplied a jump from body(negative) to the device with a needle clip to back of plugged in electrical connector and see if it clicks also?

Appreciate the video. I have a rusty bolt too and need to get a bolt extractor kit. Why not replace the rusty bolt once off?

Thanks very informative video

My 08 impala has been a great car for the most part. I have owned mine for years and havent had any major.issues...however, I just hit 200k miles and things are seeming to go wrong, one after another. Including this exact issue. Not to mention the ubiquitous known "power door lock" issue. Its.funny, my check engine light is intermittent, but everyime i get fuel, the pump constantly shuts off. This will hopefully be the solution. Thanks!

It’s very helpful thank you

would like to know what scan tool u use, it looked like the think tool, looking for a budget bidirectional scanner

I'm going to invest in a scanner 👍🏾 .

I’m reading 0v on my connector, there was a flood in my area a while back and I’m thinking a fuse got blown. Do you know which fuse this is related to

I wanted to ask if the engine harness was shortened and someone messed with up does it caused malfunctioning to the vent canister working ?

very good video and well explained,what about the scanner what brand is it,Thank

I've been having the hardest time trying to get that sensor off, no matter how much I try it won't come out even with wd 40. Any ideas of how I can fix this?

i got two P0449 codes 1)EVAP system vent valve control circuit/open 2)evaporative emission(evap) vent solenoid valve control does this mean its just the circuit or both? Can it also be the gas cap or would the reader would have said that? if you can give me your thoughts on this i would greatly appreciate it THANKYOU NEW SUBSCRIBER

You can check cannister by jumping ground to back of attached connector to hear it click>>>>

This would be the same with the 08 ss correct ??

How much was the part?

What is Code p0446?

What are the symptoms of this? This is the only code I have and my car surges a little at idle and the all the lights inside and out will dim and brighten while driving and parked

I need to change mine out ,but my plug was ripped out, when I had a blow out and I can't tell where it was attached to car

I replaced the solenoid valve, and the engine is still on, and I drive it for two days and still engine light.

will the engine light go right off or will it go off later

I felt like the rust was falling on me

Dude sounds like Will Farrell
