I wish this guy was my teacher for every class throughout school; I would have probably obtained several doctorates by now. A great teacher is everything, and this guys puts on master classes for the uneducated and ignorant many. THANK YOU !!!!!!!!!!!
Im been getting p0446 code and have replaced the valve solenoid, purge vent, fuel pressure sensor, and the vaper canister, gas cap (oem) and checked for leaks and i dont know what else to do
Any ideas if i get the code, my power seems reduced, i smell gas in the cabin occasionally right after starting, usually only if i havent driven for a while so if its sat a while. I havent checked mileage but its probably also down.
I’ve been driving with this same exact code for 4 years now . I have a Chevy Malibu 2004. Out of those 4 years one day the check engine light magically disappeared but it’s back again. Idk wtf the issue is.
Where is this located on a 2013 GM Avalanche? Is this an EASY or HARD fix?? My mileage sucks! (Auto Zone used a scan tool. I’m not electrical or mechanical inclined on this truck.)
i go over water puddles and it starts missfiring and when it rains i cant drive it untill its not wet anymore what piece do i need for a 2003 chevy too fix this?😔
Sounds like an issue with the vent valve or vent valve wiring. The vent valve is likely built into the charcoal canister. I would test the wiring and then swap out the charcoal canister.
Can I keep driving with this code? I have an appt with mechanic next week but I went to put gas in and it was pressurized and vapor/air came out and I was only able to add $13 of gas before the pump kept auto shutting off. I was near empty and it should’ve taken much more gas. I’m also notice some acceleration delay.
If the purge valve is stuck open, it lets gas vapors into the engine, which can cause more fuel in the cylinders than usual. If that happens often, there are often long start times. Your purge valve is likely not stuck open, or you would have noticed issues.
Update: I made a full video on all the EVAP components and how to test them; here is a link. ua-cam.com/video/C5s3Rx3wjD0/v-deo.html

Dont forget about vent line that goes to filler cap the filter gets clogged and even the line
Got 2012 GMC Sierra slt 4x4
Thank you for the information! Clearly explained, just what I was looking for. Well Done!
That was a wonderful explanation on the system and how to do it I really appreciate your information thank you very much
2015 GMC Canyon with this code popped up today. Thanks for the info.
Commenting to help the algorithm, great information i wish i had sooner

Smoke the system for leaks

Great video. Thank you!
Great video thanks for sharing my man
Thanks. I CAN DIG IT.
Great video
Thanks I can dig it.

How would you go about testing electricity parts in the truck. Im trying to learn as much as i can about it but don't know how to diagnose issues
Hi ,thanks for the video, do you think ,don't replace sparks on a long time, could cause the code also ?
Spark plugs would affect how the engine runs but won't affect the EVAP system.
@@HVAC_Mechanic dust, old hoses, cracks

Misfiring? It might be your spark plugs needs to be replaced
So what if the mechanic fixed all that. He said light goes on but wont throw a code
You’re the man

That is a common symptom for a bad vent valve. You should have no issue when driving, but it will not pass an emission test.
How much would cost to fix that ?
Would this cause a delayed start
The only component in an EVAP system that can cause engine problems is if the Purge Valve is stuck open; otherwise, the system is separate.
👍
Can y drive with this my 30 year old Toyota has this code runs fine
If the purge valve is stuck open, it can affect the engine; otherwise, it will just not pass an emission test.
@@HVAC_Mechanic how can it affect the engine? Also, my car does not need an emissions inspection. It is too old.

i’m not gonna say u can, but i do

Yes but you will burn gas like crazy
Im burning gas like crazy
I have gas like crazy
God save
Me too
So you'll burn gas like crazy if this is out
