Tonya,

My OXS and Alt. lights come on together too when there isn't enough
voltage.  I found my problem was the alternator pully slipped. You might
just need to check your belt and your charging system in general.

I think it's just afreak thing that both lights go on when I found it to
be a charging problem.  Oxy Sensor was fine.
