Tools/Parts needed:
Nissan Pathfinder Knock Sensor ($25): from Amazon (http://goo.gl/WHKa7) or Rockauto

Step by step process for relocating the knock sensor in a 1999 Nissan Pathfinder to avoid the tedious task of taking the air plenum off. Filming was done with my micro 4/3rd Panasonic GF-1 camera w/ 14-45mm lens.

  • I have a trouble code for this on my 00 xterra gas milage sucks! Did yours milage improve after this Mod?

  • @102sammy yes - when the knock sensor isn't functioning properly the power output of your engine is reduced to protect it. This results in decreased gas mileage.

  • Hey Great Video.... I have a 2000 Xterra and the check engine light keeps coming on... Scanner is showing a Knock sensor code. Will this Mod work for my xterra as well?

  • @iplayinedge Yes, most likely it will.

  • Don't knock it till you try it...

  • Thank you so much. This is sooooo helpfull!!!!

  • Nevermind. Just got a harness from nissan, it was 30$.

  • Can i use my original harness for this if im able to get it off the sensor without removing the intake mani? Can i pull out the wire if i take the distributor off?

  • can i do this to a 1998 pathfinder looks like a quick and simple fix and i need to repalce mine tomorrow before the superbowl an do no want to spend all day. thanks for the help plase let me know

  • @102sammy I have this code too. My gas milage is 16.4 mpg on a 2wd crewcab frontier. Manual tranny.

  • @superch11 You will get a code. This code won't trip your check engine light.  Have a buddy or autoparts store plug in a obd2 computer.
