Yes, I searched those codes before making a new topic and did not find anything. My main question is what the manufacture's part is number? What are some recommended replacements?

On a 2021 model, shouldn't this still be under warranty? Have dealer resolve it at Nissan's cost, not yours.

He might be over on mileage for basic coverage on a '21, but it's probably still under drivetrain or emissions. Both of those codes are for slow response on the A/F (front O2) sensor. If the wiring is good then it's probably a bad sensor.
