The location is directly under the steering column. You will see the OBDII plug. In order to read the code, you need a wire/paper clip. I cannot remember off the top of my head which two holes need to be jumped. LOL but all you do is make a circuit and then turn the ignition key to the on position and record the number of times the CEL flashes. This is a chitty explaination. Just go to Autozone and flip through the Haynes manual. It's really straight forward.
