02 sensor

Hi all

been using my nissan data scan just to see if all is ok but my o2 sensor reads nothin . can this cause it to run slower and rich ect??

Does it read something when you hit the accelerator ? It should flicker between 0 and 1 when on throttle.

nope it does absolutly nothin but if i unplug it on the data scan tool is says lean unplugged and when plugged in it says rich but does not move on the gauge
