So could my code scanner be finding a problem on the left side and be reporting as a bank 1 (right side) dtc?

I have replaced both right sensors and still get p0133.

When I first received the p0133 I replaced the bank 1, sensor 1, which didn't fix it. Then I used a "car chip" dtc scanner that graphs data onto my PC. Bank 1 sensor 2 seemed to be inop with constant voltage at about 1.35volts (other 3 sensor data displayed an active wave of voltage between .1 and .9 volts). So I then replaced Bank 1 sensor 2. This still has not fixed my problem (check engine light with p0133).
