Check Engine Light

I'm trying to prep my truck for selling and fixing all of the "problems." Code 341 pops up. I know what the code is, but I don't know how to fix it. I am not a mechanical guru, but I am not a retard either. Can someone give me some insight as to how to tackle this code. Thanks in advance.
