I'm almost certain that's the O2 sensor on the bottom of the catalytic converter in the back of the engine. Which sucks because it's not all that easy to access. I believe it can be accessed from the bottom of the car but not certain.
Has the code only come on once? If so, I'd reset the ECU and see if it comes back.

I tried to reset the ECU and it came back after 5 minutes of driving. I tried it twice but the check engine light came back again within 5 minutes of driving. Might try changing that sensor on the weekend and see if it’s the issue.

If you're clearing it and it's coming back, it's clearly a problem

Did you disconnect the battery to reset the ECU or by OBDII scan tool? Try to disconnect the battery to fully reset the ECU if you haven't try that.
I had P0430 and could not clear it via OBD scan tool; it went away after disconnect the battery. The code has not been back; fingers crossed.

The code is for o2 sensor bank 1, sensor 2 circuit low voltage, which losliglo is correct about the location, lower rear sensor which requires access from below and above-unless you have abnormally long arms to disconnect the plug, and if so, please post pics of your abnormally long arms.
The code will only clear with the engine off, ignition on. It can be caused by multiple things, including an exhaust leak near the sensor, or a loose wire. Or just a dead sensor. Would require a bit of troubleshooting
