Question
I have a 96 oldsmobile cutlas ciera and I have 5 sensor codes that are keeping my check engine light on.

p0121, p502, p0753, p0758 and p1864

Answer
    Except for the first one all these are transmission trouble codes.  Since these are digitally controlled transmissions, I suggest you go to a reputable independent transmission shop for repair.  You aren't going to be able to do this yourself.  The first code is normally a MAP sensor, but I would suspect it is something else in this case.
