My CEL popped up last night. I scanned it and it read P0449 - evaporative emission control system vent valve/solenoid circuit. From what I've read, this could be the Vent Valve or a Blown Fuse (I've ruled out the gas cap). Where on the 09-15 CTS-V is the valve located? Does anyone know what fuse # I would replace if it's a blown fuse?
