It's the bank 2 sensor 1 that's is telling me that the voltage is too high. Before this code, my car used to be lean on bank 2 with the code P2197 (O2 sensor Signal Biased/Stuck Lean Bank 2 Sensor 1).
After the fix, the sensor was telling me code P0152 (O2 Sensor Circuit High Voltage (Bank 2 Sensor 1) First thing I did was goto autozone and get a replacement to see if that worked first thing. Same code popped up. I looked at live data and it shows the sensor at 1.25V and instantly dropping to about .4V and then instantly going back up to 1.25V.
I was unsuccessful with research and was hoping to get some other people's help. Anything is appreciated!
