P2442 code . I need help!

I have 2007 tundra 4.7l v8 . I got P2442 code secondary air injection system switching valve stuck open bank 2 . What can I do ? I looked at the messages and videos and saw 3 different pieces. I'm not sure which one to change. Can you help me and how can I solve the problem?

 

Look at Hewitt systems bypass. It might help you.

 

Will the check engine light still on after using the Hewitt?

 

I don’t believe so, go on their site, do some research, ask them your questions.

 

thanks for help

 

I haven’t used them, my truck is fine for now. If mine go out I’ll bypass them. A few guys on this site have used them with good results. Good luck.

 

Yes. You will want the 2nd generation kit for a 2007. Install the kit and clear the code it won’t come back. If you have further questions the Owner of Hewitt would be happy to answer any questions, Hewitt is a small operation all you have to do is call him

 

You can either install the Hewitt bypass kit or replace the switching valve which connects to the valve cover. The SAIS has failed twice on my 2007 Tundra. The first time at 135k miles which was replaced under warranty and the second time at 250k miles which at that time I got a Hewitt kit.


If you replace the valve make sure it is OEM not a cheap aftermarket, if you replace only the failed valve don’t be surprised it the other bank also fails

 

Thanks for the information. I replaced the valve bank2. it's easy. I got from the rockauto. There is no problem right now. If it happens again, I will bypass it.

 

You can also just bypass the SAIP by doing a DIY kit. It essentially turns the SIAP off and doesn't read for it at all. Here's the instructions on how you do it. Works great. and only a few dollars with of parts.
