The knock sensor alone will not throw the Check engine light most if not all 3.3 motors Frontier or Xterra have bad knock sensors not a big deal unless you have the S/C motor. The sensor is located under the lower intake manifold passenger side so to get to it you need to remove the upper and lower intakes or if you do a little searching on www.nissanoffroad.net there have been a few who have relocted the sensor using a Nissan maximum harness and sensor.
