Jaguar Check Engine Light Codes

Welcome to the Jaguar Check Engine Light codes page. Below you will find the most complete list of Jaguar 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? We have a large number of resources to help you repair the problem.

Here is how we suggest you proceed. Look up your code definition. This tells you where to start testing. If you are unsure of any abbreviations, check out the acronym list by clicking on the link at the left. Next, read our article Automotive Circuit Testing 101, and if there is an article related to the system you are testing, such as Oxygen Sensors or EGR concerns, read these as well. They will provide valuable info! If there is a link to a specific diagnosis strategy for the code then follow that and start testing. If there is no procedure for your manufacturer specific code, then I suggest referring to a similar generic OBD II code (these are listed numerically by system type) to get a good idea of what to look for. If at this point you still need assistance use the "Get Help" link and let us know how we can help. We can provide information on component location, specifications, circuit color/location and more. We do ask that you please read the info available on the site first so that we can help reduce repeat questions. So please read our Disclaimer and when you�re ready jump in!

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 Jaguar 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 Jaguar check engine light codes with an OBD II scan tool, proceed as follows:
1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover.
2. Turn the ignition on.
3. Follow scan tool manufacturer�s operating instructions to access the Diagnostic Trouble Codes (DTC's).

Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other Jaguar diagnostic trouble codes.
