My battery took a crap on me, had to get it jump started, battery done it before need to change it asap(tomorrow)... but before the check engine light didn't come on? Is it a coincidence and something else came up? I'm also due for an oil change too.

Yes, I know i need to get codes, but what are possible things throwing it off? 02 sensors? Gas Cap? or is it the dreaded battery?

Thanks guys!

It could be a low voltage code caused by the dead battery. I would disconnect the neg. batt cable for a few minutes and see if the CEL is still on when you hook it back up. If it's still on, then you can get the code(s) read.
