You need a charcoal canister and vent control valve.
You also need the EGR solenoid valve (I think it the brown one).
Valve is located in the valley of the V, towards the transmission side of engine.
Do these 1st and reset light. You may have other issues but you have to start here.

check ur gas cap for tight and proper seal that is the most common problem for the the evap codes if cap is good check fuel and vent lines for damage or leaks from gas cap under vehicle up to engine compartment

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.
