If your talking vent I just jumped the wires one thing that really confuses me is says the service port goes to charcoal canister not gas tank in my chilton.

The vent is t the back of the truck on the frame. If the purge in the front passed the test, the vent is next.

You would need to apply voltage to the vent solenoid manually if you do not have a scan tool that can do this. Make sure the valve opens and closes.

I attached the flow chart for the 443 code below. I also attached a wiring diagram of the vent solenoid and the purge valve for you.
