There could be many problems with your car depending on the code. For instance, you have to go to a mechanic or car shop for them to hook this plug up to your car. It will give you a code and that code will tell you exactly what is wrong with your car. The MIL came up on my car before and I had to change the thermostat of my car. Once you have the code, you can just google it and it should tell you the problem as all the codes are generic. Hope this helps.
