Fuel Cap codes

[snance]

Popped a CE light and apparently the code if for a fuel cap according to auto zone. Put a new cap on and code is still there. Bought an evap canister and will put that on soon. Wondering if i could order any other parts or any other areas i need to look.

You need to diagnose it properly instead of throwing parts at it. Auto zone gave you a maybe.
Did they give you the actual code number?
