glad you've found it. before you buy a new sensor, fix the connection, reset the computer, do the oxygen sensor drive cycle and hopefully both codes should go away. if one is off the other may be off too.

 

Hey everyone, I think I may have solved my CEL problem. I returned my first 02 sensor and got a new one for free, (under warranty) took it home and had it installed. I reset the ecu with the battery method, and the light hasn't come back on ... yet. And I have driven it about 6-7 times by now. Either the first one was bad, or maybe I didn't screw it in all the way. But who knows, thanks for everyones help.
