I cleaned the CPS connector but the sensor itself could be bad. Can a
bad CPS keep the check engine light from turning on right away? I
think the computer allows about 3 seconds to get at signal from the
CPS but I don't know if others have reported the check engine light
not lighting due to a bad CPS. Thanks

The FSM says that not all '95 YJs have this ground wire. Mine doesn't
seem to have it (but it still worked fine for a long time before this
problem started).
