Hi New to forums, but maybe someone can help.
I just got a DTC Code of P0442 clear it to see if it would come on again then got P0449.
Something to do with the "Emission Control System Vent Valve/Solenoid"
Does anyone know where the vent valve or solenoid are?

P0442 said a small leak and I have looked up these errors and someone said it could be the gas cap that's bad.
Any help would be appriciated.
Thanks
