Secondary air injection system on 2010 Tundra

Posting to this thread too:....HI All. New to this forum for posting, but I have used the threads for help with things in the past. Thanks

I have been having this issue for over a1 year. Basically I got the CEL and ran the codes. I got P2442 (Secondary Air injection system switching valve stuck open bank 2) and P0418 (Secondary air injection system Control A circuit) It throws up the CEL which was fine for a while, but then if I did not clear the codes, it would put into limp mode. I now have to stop if happens while driving or before and clear the codes, so it comes out of limp mode. I did the research on this and I know replacing the system from dealer cost like $3K or that is what I was quoted. Since it is a 2010 and 160K miles, it is no longer under the warranty or recall. Apparently there was a recall, but it was past the mileage already so they won't honor it. I need some advise because this has become really annoying. Once codes clear, it's fine. I am ok with CEL on, but limp mode is an issue, unless constant CEL on is an issue. I would not be able to replace the pump myself if I bought. Would a non-dealer shop be worth looking into? I had one tell me they wouldn't do it. Is it worth investing in the Bypass kit from Hewitt Tech? https://hewitt-tech.com/product/sec...apAk0L726PF4PU7Oiu2v81CmYvEGUZLX0UAJOeWuRPAny advice is appreciated.

Any advice is really appreciated. Thanks! Steve
