    I have an 07 5.7L. It threw code P2442 air injection valve stuck open and went into limp mode. I replaced the valve and it worked for a day but now getting codes C1201 ABS inlet valve coil LF circuit short to ground and P2438 secondary air injection system. I see on a lot of videos to change out the air pumps also but i took mine off and ran them for a while to make sure they were dry and working and they worked perfectly. The truck is staying in limp mode. Any help greatly appreciated.

    Just buy a air injection bypass system because it will most likely keep causing issues from every part you don't replace. Unless you live somewhere that requires it.
    Look up SAIS bypass on here and you should be able to find threads on it.
