Just wanted to share with you guys my Camry was coding the check engine light. Doing some research and it looks like there are about 4 types of OBD II ports and not all of the corded readers work with all of the types. Wasn't really interested in a Bluetooth one but it was inexpensve, worked with EVERY OBD II port, and Android (only) phones. I bought the app Torque Pro for $5. VERY happy with it, basically fool proof and was able to clear my code along with seeing many other live engine functions. I am pretty impressed.
