Ford Check Engine Light Codes
Welcome to the Ford Check Engine Light codes page. Below you will find the most complete list of Ford trouble codes available. The code definitions are a good starting point when determining the cause of the service engine light but where do you go from there? Also, we value your feedback and like to hear stories of unusual fixes or concerns you may have run into with your Check Engine Light, so feel free to share your experiences by using the "Contact Us" link. Let’s go!
We do our best to update these Ford check engine light codes as frequently as possible. If you find one missing let us know and we we'll add it immediately! Please use the form on our Contact Page to get in touch with us. We certainly understand how frustrating it can be to look for a code definition and have it not online when you need it. And lets face it, if the service engine light is on then you need it now! It's easiest to use the "Find On This Page" feature of your browser's "Edit" menu to find codes on this page as the list is quite long. These are listed in numerical order for easy searching. When retrieving Ford check engine light codes with an OBD II scan tool, proceed as follows: Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other Ford diagnostic trouble codes.
