Default Installed O2 Simms and SES light came back on after reseting the ECM!

What in the world could be the deal? I unplugged the O2 sensor and just plugg the simms in and took a actron code scanner and deleted the SES code and it came back on yesterday(installed the sims the night before)

This is on a 2000 Chevy Pickup that belongs to a freind of mine. We order them from Thunder Racing the other day and plugged them in...

What gives?????????????

I can't really recall but he said that it was the same code as the one BEFORE the O2 Simms. It had something to do with the rear o2 sensors.
