2019 road king with 475 cam and PV tuner. Bike is running well but I got a po152 code rear o2 sensor hi. I’ve gone through the clearing process but it doesn’t seem to go away even after my screen says clear. That is once it came on it has stayed on no matter what I do. Thanks for any insight

Check and clean the connection for the rear O2 sensor. If that doesn't work replace the sensor, they are not very expensive. May be covered under emissions warranty.

I finally got it to go out after a ride I stopped for an hour came back out started bike and it was off. Maybe it took a couple of cycles to clear not sure.

O2 codes look at how the O2 sensor is working over time. So it's going to take a couple of ride cycles to set a code if they are bad. If you clear the code they should be NO light when you first fire the bike up and ride it a few times. Keep an eye on it after your gone a few rides when the bike is fired up cold and run and ridden for at least15 minutes.
