I have an O2 sensor that flags the Service Engine Soon. More of a nuiance but..when I asked at the dealer in passing they said that the ECU would need to be updated since the software was not compatible to the new sensors. I have yet to do it then. However I am restoring my Pathfinder and am intersted if you have replaced your sensors yet.
