    Gang,

    I posted this a while ago concerning a handful of CELs I was getting:

    http://www.ferrarichat.com/forum/348-355/390064-cel-codes-p1448-p1445-p0153-p0159.html

    Advice was helpful but I'm finding nothing in the WSMs for how to correct these issues. I see the thermocouples on the cats but what am I supposed to do here? When folks say things like "swap out the ECUs" and "check to see if the bypass valve is stuck open", I have no idea what that means and where to even begin.

    Can someone direct me to a resource explaining how one does this? There is some discussion about thermocouples and the like in the WSMs, but nothing on process or steps. Gotta clear these CEL faults ASAP.

    Thanks all.

    Not sure there is a "procedure" per se....

    Shut the battery off.
    Locate the ECU's you want to swap.
    Unplug them.
    Unbolt from the frame
    swap location
    reinstall
    Turn battery on

    It is pretty intuitive. If this process makes you nervous take it to an independent shop. They should be able to do this in under an hour of labor.
