Check engine light - P2097 code?

Hello, before replacing the sensor, since you have a scan tool, you should be able to go in a look at the live engine computer(ECM) data and we want to see what the voltage reading is for the Bank 1 Sensor 2(rear)B1S2. I will post a diagram of where the sensor is as well, but oxygen sensors can end up with their voltage reading being either stuck high or low. It may be a defective sensor, wiring issue, or potentially a failing Catalytic converter, but thankfully its not setting a code for that yet.

Here are the diagrams for the B1S2 oxygen sensor location. Along with the wiring diagram if there happens to be damaged wiring under the vehicle.
Here is a guide to help, but let us know what you find.
