P0137 - Zero Volts O2 Sensor

[58Willys]

Happy 4th Everyone!

2018 3.6L - Couple of months ago I had an oil leak on rear of Bank 1 valve cover, fixed it all good. A few weeks later got a P2096 and P 0171 codes. Installed new Bank 1 downstream O2 sensor, all good. Yesterday got a P0137 code. No oil leak now, all clean. Checking live date, I have zero (0) volt reading on Bank 1 Sensor 2 (downstream).

So do I have a bad O2 sensor, or a wiring issue? I'm thinking a wiring issue as one screen shot of live date had .21 v, and the rest had zero, so a bit intermittent. I have the wiring diagrams, but haven't been able to find to O2 diagram yet; anyone know what the power wire to Bank 1 downstream sensor is? Bad ground?

Any other ideas?

Thanks!

Did you use an OEM O2 sensor? Make sure it is plugged in still, and check fuses.

Use oem o2
Also if oil got on the sensors they are gonna go out over time. I had two get ruined from a dealership oil spill

Used a OEM sensor, one of the white signal wires is bad. Waiting on new one.

I've had to replace o2 sensors on practically every vehicle I've had, they don't last forever. I would replace the sensor while I'm in there
