Great explanation and how to for DIY. Well done. Thank you.
D - Thanks for the feedback! We hope it helps.
Also causes remote start not to work
L - It's possible!
Any check engine light would do that too
Do you have part numbers for the two parts you replaced ?
B - It depends on your vehicle.
@ where would you recommend looking for the part numbers for a 2010 Chevy Silverado 1500?
So can this effect why my gas gauge won’t go to full bc it’s stuck at half a talk even when I put gas in it
Clean the mass air flow sensor
@@garyteeters-ok3hcthat will not effect your gas gauge.
I - Do you have this engine code?
What did you do to fix the gas gauge mine is doing the same thing?
Throw some Techron in there that fixed mine
my ford eacape have a code p0401 too less flow..shoul the mechanic clean the other egr parts?engine have knocking on first start,but vanished when the engine is hot.what dou think is the problem,i have 2.0 engine
M - We have a video on this code that may be helpful: ruclips.net/video/LoAqvay0HEk/видео.html
Great video. Thank you. Which of these two fixes actually fixed your truck?
It was the purge valve solenoid that did it
Could a gas line leak cause this code?
K - A P0449 code (Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction) is typically caused by an issue with the EVAP system vent valve or its electrical circuit, rather than a direct gas line leak. However, a gas line leak could contribute to related issues in the EVAP system, as it might disrupt the system's ability to maintain proper pressure or vacuum. Keep us updated!
@8020Media ok, thanks for the quick reply
Is there a way to test which one it is? Autozone wont let you return parts after install
I mean you can pull one and try to manually clean it and see if it gets better or the code goes away. But both parts are like $30 so worst cause you end up with a fresh evap system and -$30 more than it should have cost
so i have a 2007 chevy malibu ls 2.2 engine and I'm getting a po449 code also, i went and bought a purge valve to hopefully get my check engine light off, do you think it will be that purge valve like in your video or the vent valve
B - It could be. We can't say for certain that it will be.
@@8020Media knowing my luck it will be the vent valve lol, the purge valve and gas cap i ordered should be delivered tomorrow, i should have it replaced and let you know if the code got erased, you did a great job on the video, keep up the good work
B - Thanks for the feedback! We hope you find your solution. Keep us updated.
So I replaced the purge valve and added the new gas cap but it didn't clear the code
B - Give it some time, or if you can reset it do that. May take some miles after. Keep us posted.
Hey, thanks that fixed my stuff
T - Thanks for the feedback! Glad it helped.
Good info bro thank you
B - Thanks for the feedback! Hope it was helpful.
Replaced everything you mentioned and still have the code. Any ideas?
M - Have you cleared the code?
@@8020Media yes several times
M - Interesting. Have you taken it in to be looked at?
@MarkHollandsworth-b2v did u check for power in wiring
where is the Vapor Canister Vent on my 2001 1500 silverado?
P - Here's a video that will help: ruclips.net/video/FDJrQFxeOos/видео.html
THANK-YOU SIR !!
R - Thanks for the feedback! We hope it helps.
Thanks a Lot My friend
L - Thanks for the feedback! We hope it was helpful.
Change tank cap, both parts and still the same code. It can be fault part.
W - True! Keep us updated.
THE ISSUE IS YOU WILL FAIL SYNDICATE GOVERNMENT EMISSIONS, MONEY MAKER FOR GOVERNMENT GANGSTERS !!
