Sensors - Swapped out at 70k miles

I swapped my original secondary O2 sensors at 75k-80k miles. The one on the drivers side was just not reading right. It had been this way for a year or more. Very slow to read low to high on my torque OBD2 app. The passenger side O2 sensor read fine, but I change these sensors in pairs. I got them on Amazon, the same ones as Nissan would happily gouge you for them. Last time I checked Nissan wanted double this amount.

The original primary O2 sensors are still on the car. I do not use any of the quick fix anti fouler or other interesting attachments. They are mounted right into the Berk HFCs directly sensing the exhaust flow.

Sorry just realized your post is for 2014 and up but mine is a 2013. Although I don’t think it would really matter. I did look up the DTC through a database from work, and the “Possible Issues” are O2 sensors, wiring, connectors, exhaust leak or PCM. Betting that it is a leak or possibly part of the sensor(s).
