Guy's he wanting to know how to check for engine codes, not what they are.

Look under your passengers floor board, pull the carpet back from under the dash section. You could see a metal plated bolted to the floor with (4)10mm bolts. The will be a small hole in the center of the plate, that'll let you see the ECU and if it has any code whats they are. You will see a single red LED that blinks off the codes. A single short blink = 1, a long blink will = 10, add together the blinks to get your code. If you have multiple codes, there will be a brief puase b/t code sequences.
