2009 saturn aura code p0449

I'd say try putting the cap back on and resetting the code, to see if it comes back if it does it's your evap canister solenoid which the part will probly cost a bit, but you may be able to get the dealer to fix it under an existing warranty

thanks you, i'll try that again With the gas cap. warranty is over on my 09 saturn, unleess it's an recall issue
