engine codes

[4LO4ME]

If your tj wrangler throws a check engine light you can put the key in the ignition and turn it off and on three times and leave it on it will run a diagnostic check and throw a code for what the problem is. If this happens i have a list of the codes and what they mean in a file. When i learn how to post stuff like that on here i will.. just a little jeep tech for ya.
