People tell me that I can bring my car to autozone to have them check it, but I want to see if can do it myself.
Thank you in advance for any information that you can provide.
Take a paperclip and put it in the obdII port under the left hand side of the dash under the steering wheel. stick it into holes 8 and 15 and then turn on the car. read the code two long flashes and three fast = 23 see my chart below....
