Is your car's Check Engine Light on? Do you want to repair your car yourself rather than take it into the shop? Are you a shadetree mechanic (DIY)? If so, then this site is for you!

This site is the premier OBD-II ( a.k.a. OBD2 ) trouble codes resource site. Instead of just giving you a cryptic description of what a trouble code means, we offer a lot more information on trouble codes: troubleshooting tips, symptoms, and possible solutions. We strive to give you the most troubleshooting information as possible, in one site. We also feature car repair forums, where you can ask questions, totally free.
