Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello. My name is ***** ***** I will be assisting you today. I believe that your issue will be the EVAP vent solenoid, or the EVAP canister itself. Both could potentially create this issue because of the pressure that gets built up in the tank. I am leaning more toward the canister failing. The charcoal pack inside sometimes burst and clogs the canister preventing proper circulation. The valve could also be stuck closed, causing the pressures to rise.
Give me a moment, please, to review a few things.
Here, I am providing some testing information for the valve. The canister will have to be visually inspected, which will require removing it from the vehicle.
I have attached canister replacement procedure for you. Also, I have attached component location information.
You should have these components (EVAP canister and canister valve) inspected and replaced as needed.
If you require more information on this issue and/or are not satisfied, let me know, please, and I will attempt to assist you further on this. I hope this information points you in the right direction. If you have any further questions or concerns on this issue, feel free to ask. If you are satisfied, and have found this information helpful, a positive rating would be greatly appreciated. Thank you.
A positive rating does not close the session. We will still be able to communicate and I will continue to assist you with this issue as needed
