    Hey guys I recently purchased a 06 Tundra Xsp. Just recently the check engine light came on and when I get on th highway the truck won’t go past 65mph. Anyone know what the issue could be?

    Sounds like it went into limp mode. Go get it scanned and see what the codes say.

    I will later today and I’ll get back with the codes. I did some research on the internet and most of what I found is that it’s possibly in limp mode like you said. How would I fix that?

    One or more codes is causing the limp mode. The code will have to be remedied to get out of limp mode.
    good luck

    I got codes p0418, p0441, p0455, p2445, p0456. I believe it’s the SAIS circuit/relay A circuit malfunction bank 1. Where is this relay?
