    Had a recent " check engine " light come on . Had scanned , P1442 and P1445 ." Secondary air injection system switching valve No.2 stuck close bank 1 and bank 2 . Researching reveals very expensive repairs . Heard about a relatively simple ( and cheaper ) kit to bypass this problem . My question : I live in an area requiring emission testing at auto registration yearly . My understanding is these codes are an emission failure and will not allow me to register my vehicle . Will this bypass kit fix the problem or will the CEL still fail me on the emission testing ? Any experiences or advice anyone has to offer will be truly appreciated .

    From what I’ve read, you won’t have the CEL come back so emissions shouldn’t be an issue as long as you clear the code.

    I have a 2006 Double Cab that started making the vacuum sound associated with the secondary air pump when I started the truck. After reading forums I realized that this could possibly lead to certain codes related to the secondary air pump so I went ahead and installed the bypass kit from Hewitt-Tech. I didn't have a CEL but it was done to hopefully keep the problems away. I didn't even have to install the block-off plates for the exhaust that are needed for most if CELs show up. I had to have my inspection done about a few weeks ago and I live in an area that requires emissions testing. Didn't have any issues with the truck passing. Take my experience for what it's worth. Hope that helps.
