Check engine light

I got my first "check engine light" on my 2019 JLUR (January delivery). A buddy had a code reader and it came back as P0137: O2 Sensor Circuit Low Voltage Bank 1 Sensor 2".

I cleared the code and we'll see if it comes back after a bit of driving.

Has anyone had any experience with this code on a JL?
 

Are there 2 (one on each header) wired in series? Just take it to the dealership and have them replace it. Does it smell like shes running rich? Could be a bad injector also.
 

Closure

The issue ended up being a fried O2 sensor. Root cause was a leaky engine gasket. Oil was dripping down on the sensor. FCA fixed the gasket and replaced the sensor under warranty, but I had to pay for part of the labor (for them to remove the battery/tray) to get at the engine, because I replaced the stock tray with a Genesis dual battery set up.
