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

 

The Hewitt kit is definitely a good option. Not done it myself but have read about others that have. The secondary air pumps are not needed and costly to replace. Hewtt gets good reviews with good customer support too.
