Turn your car key in the 'On' position. Your CEL light should blink a few times, pause and blink a few times again. For example you might get this: blink, blink, blink - pause - blink blink. This would be a code 32. Once you know your code, post it in here and someone will look up the problem for you.
PS: If it keeps on blinking, then it means there are no problems.
