check engine light comes on when car is warmed up.

[johnavery]

I have a 94 mx-6 ls,manual,6 cyl. When the cared is warmed up the check engine light comes on. I think it might be the temp. but the radiator fan kicks on the the coolant levels are good. This is my first mazda so I'm not really sure what the problem is. If any has had this happen or knows what is wrong, i would apprectiate the info.THANKS
