i got in an accident and i finally got enough money saved to fix up my 89 crx and i got it started but i got the check engine light. how and where do i check the codes?

 

look at ur ecu under the carpet on the passenger side and see how manytimes it blinks one long blink is 10 and every short blink is 1 so if it blinks 2 long times and 3 short ones its a 23 got it? so find out what code it is
