I am getting a P0446 code and it states that it is the vent contol circuit. Does anyone have a diagram stating where all the parts and names for the EVAP system? The truck has had the TSB update as it has a 08 canister in it and the hose is relocated to the bed of the truck. Took everything out, blew it out with air..and cleaned the electrical hook up that is by the canister also with some good electrical cleaner. So I am trying to figure out what next..and the diagram will tell me what is what. Thanks
