Come along with Eric O at the SMA shope as he diagnoses and repairs this GMC Sierra that came in with a check engine light on and a DTC P0449 “Evaporative Emission (EVAP) Vent Solenoid Control Circuit” Now this is a really common problem that plagues these Chevrolet and GMC pick ups and is an easy one to figure out! Thanks for watching!

Eric would this cause the vehicle to run rough and stall once it reaches operating temp this is the only code i have on a 2005 5.3 chevy tahoe starts fine runs fine till it reaches the operating temp then she will run rough vibrate and stall…try to start it after it stalls wont start unless i play with throttle starts then stalls..I let it cool down starts and runs fine again till it reaches operating temp then same thing happens again.

Can this cause P0174 and P0171 codes and cause a truck to bog down in rpms while idle?
I am just interested in the older trucks.96 to 2000 gmc / chevy .
Cheaper and easier then Toyota
Please somebody tell me what that filter part is called at 9:21 ? I’ve looked up diagrams and couldn’t find it. Mine is hanging down full of water and dirt i dont know how it got disconnected in the first place
I've seen those stupid little filters in 3 different places on the filler, up on the frame, and clipped to the trans. All seemed to be factory
I keep having issues with my dang 2015 Sierra 1500. Every time I get one code figured out, another one pops up. Your videos have been a great help though
The small filter up by the filler tube , can't I just zip tie that anywhere that gets clean air ? Somebody zip tied mine to the very top of the transmission where I can't hardly get to it. Thanks in advanced.
Was there other codes that could have come up when the Evaporative Emission Vent Solenoid Valve Control Circuit malfunctioned?
Ok I have no code but the hot light is on the scanner? HELP
I get the circuit malfunction code for my evap on my 96 gmc sonoma
Ok so I just fixed this on a 2018, not a lot of material so I am trying to share the info. I did replace the bad vent solenoid but it still ran like crap. The REASON the valve went bad was from a filthy seal on the stupid Cap-less gas tank. Wiped it off and lubed the seal ran good as new. Good luck
Yea ! Just pump that E85 in there. Flex fuel . What does that do to your charcoal? Plug it up along with everything else .
I have a 2019 and it had a 499 code took it to shop and they changed the canister vent solenoid but the engine light will not stay off could it be the purge valve under the hood ?
do this solenoid keeps the car front starting
Is there a part number for the hose going from the solenoid to the tank? Mine was rotten and broke when it came off?
Thank you very much !!! I had the bed off of my 2013 Silverado 1500 to deal with a serious rust / rot issue and I could not remember where the fresh air intake for the evap was mounted ( welders removed the fuel tank ). After several hours of videos that showed the evap canister and solenoid but not the fresh air intake I came across your fantastic video. Thank you , Thank you. Well done
Very well made how to,thank you
i hve a 2014 silverado with a v 9 i scanned it and the mine just said DTC WITH NO NUMBER BEHIND IT WHAT DO THAT MEAN .
est t il possible de traduire en frencais s v p
ca ferait bien mon bonheur
I can not find this part what is it called
Under what circumstances does the circuit activate the solenoid? I don't have a tech 2 so how can I verify that the circuit is good?
What scan tool do you recomend?
