    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.
