Reading Codes

[wettpaint99]

How do I read the codes in my 99 GTP? I don't have a scan tool, and the service manuals that I spent big bucks on when I bought them don't give me a clue. The service engine soon light has been on for a week. It still runs great. Any help would be appreciated. Thanks

Go to autozone they will read them for you with a scanner.

^x2 most autoparts will read for free.

However I bought a scantool from Linear Logic called the Scanguage II for around $150
