DTC Code
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

RE: DTC Code
Replace the cap first. After that you will want to climb under the truck and look at the filler neck it has a tendency to split. Other than that I would follow your fuel lines and look for any abnormal wear and replace as needed.
