O2 Sensor Trouble Codes?

So lately my car has started giving me these 2 codes. I clear them, and the next time I start the car, about 5 minutes into driving they return.

P0138 - O2 Circuit High Voltage (Bank 1, Sensor 2)
P2271 - O2 Sensor Signal Stuck Rich (Bank 1, Sensor 2)

I understand Bank 1 is the passenger side? Sensor 2 would be the downstream sensor right?

I'm almost positive my downstream sensors are turned off via my Diablosport tune. I have BBK longtubes for what it's worth. I'm pretty sure I still have some makeshift MIL eliminators installed but it should not make a difference if the sensors are disabled.

Thanks for any help guys.
