Is this knock sensor good? has anyone ever bought from this company before? This knock sensor doesn't look like it has a connection, is it because the connection dettached directly from the sensor?

that knock sensor is not sitting in a harness right now, which is why you dont see any wires connected to it.

i think several people from this forum have ordered from that guy Bill Curtis before and had good reports. I got my part from him (still waiting to get it in the mail)

There is another one on ebay for $45 shipped, if you type "nissan knock sensor" in the search area. those ones were pulled off new engines.

 

I believe that's who I got mine from. I bought it awhile ago and have yet to get it on the car, but it's Nissan genuine stuff.

 

You should be ok. I bought mine from him and checked the resistance and it was 550 k-Ohm, right around where it should be.
