Greetings. This fault is an emissions system problem. Most times you will need to take it to the shop. This specific trouble is pointing to a evap canister vent solenoid. Usually this is a bad vent solenoid or a broken wire going to it.

can you show me a diagram of the solenoid vent so I can check and see if the wire is broke, if not then I will take it to a shop.

You would need a lift. The vent solenoid is near the evap canister which is tucked up into the body by the gas tank. I dont' think you can even see the wires without pulling the canister down.
