I have a 03 cadillac cts 3.2 and i have a 02 sensor problem. I have swapped bank 1 and bank 2 and same problem bank 2 gets high voltage with 1 sensor .6 to 1.08 short term fuel trim is -25 and swap sensors and it will get no activity .440 short term fuel trim 0.0 but both sensors read right on bank 1 only have a problem with bank 2 wiring is good also swapped the injectors thinking maybe leaking but still the same

OK, back up. What is the exact code number you are getting before and after you did your swapping?

You're showing a short to power and a heater issue. The circuit will have to be troubleshooted thoroughly. It could be a wiring problem, shorted sensor or bad PCM.

I also unplugged the harness side of the 02 and both read the same volts with a volt meter when i got the car the 02 wire and crankshaft position sensor were burnt so replace the sensor and rewire the 02 soldered it and every thing. why would 1 sensor say high voltage and not get the heater codes
