You can turn off the Check Engine light by either disconnecting the battery or by using a code reader to clear the codes. However, if the problem still exists it will come right back on. Instead you should get the code read, find out what the problem is, and fix it. Your local autozone or checker auto parts store will read them for free.

The OBDII connector is located in the center console just behind the ashtray. There is a plastic cover that must be removed and you will find the connector behind the cover.
