Hey guys my ecotec is throwing CEL P0440 Evap Emmision Control System?? i clear the code for a couple days then it comes back on. i did change gas caps already but it still happens. is the Charcole canister done with?? or what else is there i could swap/

i do still have my ecotec swap car so i can go change pieces on the weekend.

Thanks

Greg

Maybe the solenoid by the gas tank check there could be loose

don't check it replace it #1 issue with cavaliers and sunfires for throwing EVAP Codes they are like 30 bucks at the dealer
