i just got back in from trying to check the knock sensor, i traced its harness to its connector, removed the connector, connected the ground of my tester to the battery negative, and held the positive on the pin that is closet to the front of the car as the instructions say. I started with the tester on the highest ohms setting and then turned it down through the different ohm ranges, but all I got was '1', never anything else. Does this sound right or did I screw up somewhere???

P.S. After observing the location of the knock sensor, I would like to give kudos to all who have changed it w/o removing the intake manifold, that sucker is really buried!!!

 

a 1 means that the meter is maxing out i got some weird numbers when i tested mine it was like 1.2 mega ohm then later it was 3.2 mega ohm it was all messed up man

 

Hey damnit I can't remember what reading your supposed to get exactly... I think it was something in the range of like 555 ohms...

THOUGH... I also heard here that you should connect it DIRECTLY to the knock sensor... this means removing it and reading it like that...
Reading it from the harness suposedly gave some people here some odd readings... (from what i remember....)

removing it isn't tooo hard... (without removing any item on the engine...) i'm not a mechanic and it took me about 45 minute to get it out an about an hour to get it back in... it's a biatch to get back in because you have to put the nut back into the hole... but it's doable... oh.. that's also assuming you don't have big big hands...

bringing that to a general machanic or a nissan mechanic will probably cost you big bucks cause they'll take off the intake manifold and stuff... useless to me... it's doable without removing it...

Note: if attempted, you may have to bend a small piece of metal with your hands... this will allow your hand to bend better into the position required to remove/install the bolt/ks... it's a metal that holds the pcv valve... (i think)

good luck

 

I bet you just don't have a high enough ohm reading on your multimeter.

 

its a $20 digital meter from Wal-Mart, it should ready pretty high!

 

what is the highest ohm setting?

 

I believe the highest ohm setting was 200K (i don't have it in front of me at the moment)

 

I believe I use my 2000k setting in order to get a reading.

 

the meter has 20M as its highest(then 2M, 200K, 20K etc.), shouldn't this be high enough?

 

if your meter give you 1 on all range that because your probe doesn't even touch the contact in the connector or your sensor is completly open.
