My check engine light comes on every now and then and I'm trying to find the code for it. Autozone gave me a funky looking key and said to plug it in somewhere and it will flash the code. I'm no mechanic so I have no idea what to do. Any help? Picture would be great. Thanks

Do you have a dvom digital volt meter and a test light at your disposal. To go on we will need them. We will be leaning toward a computer or module or wireing.
