Default P0411 code

Hi guys so I recently have my ac deleted, and now I’m getting a p0411 code, could this be from that? And I’m wondering can I go ahead and remove the air control solenoid valve as well? It’s making a really weird buzzing noise, the car have no cat, thx!

The code has probably got to do with the air pump. I have a test pipe and my air pump doesn't buzz so maybe you did something to it when deleting your AC? Check connections

The bulk of questions like this have solutions, or at least information, in the Service Manual. Just download and search for P0411.
