don't listen to that. it's OBDII (On Board Diagnostic II) and the computer is throwing a code to tell you that something is wrong. go to the dealer or even autozone and have them read the code for you to find out what's wrong. DON'T get the check engine light confused with the "maintenance required light". and even if the CEL comes on at 100k, that's good. 100k is the most important service your car will ever see. if you don't get your car a major service at 100k you're retarded and you deserve to be left stranded on the side of the road.
