I see them for 13$ lol, just wondering if this is a "too good to be true, than it probably is" situation... Thanx

 

U get what you pay for imho. Probably better off getting one at the junkyard

 

This guy, $15 shipped.

Still working 4 months later.

 

very good to know, thanks man, all I needed to hear...

 

I've never had any problems with mine.

 

If you search you will find a number of people that use EBAY KS's. I had one, it worked fine, I just ended up bypassing it (was sick of seeing the ghost code)

 

I have one, it's still working fine

 

thank you gentleman...

 

im using the $30 ebay KS, 2 months, no codes id say your golden

I think the cheap price is due to mass production not cheap materials.

 

yep, been 1 1/2 years & 7k

 

yupp got one for $17 bucks shipped in march still going wellso far :-)

 

my one is on its way and i found mine for $7.99 shipped....hehe

 

I bought one back in Nov 2010, crapped out after 1 month. Returned it to the ebay seller. Bought a different one in the mean time, didn't work straight out of the package. Ebay seller refunded my money. Finally received the replacement from the first seller.

 

Mine failed after a year. Meh. Not that big of a dead, bought another one.

KS are cheap because
a) Nearly all late 90's to late 00's nissans used EXACTLY THE SAME PART
b) Mass produced because see a)
c) Extremely simple part.

 

lol...here in australia i asked several shops on a price for a knock sensor and they all quoted me $180 lol...i ordered three at $5.98 each of ebay....

 

I may be wrong I know how it works just not.... How it works.... Lol

All it is is a magnet and a coil, when you shake the two it'll generate a voltage which the computers determines as a "knock", then timing gets dropped!

 

I put one in a buddys car and no problem yet

 

It is a Piezo device. Sends out a voltage signal when stressed.

 

i got mine in april last year. still going strong.

 

I bought a KS from Ebay 4 years ago, still seems to be working fine.

 

I did buy one but it was genuine nissan part.

 

The KS from Ebay sounds reliable according to this tread. Maybe, I'll give it a try as well.

 

worked fine and have no problems.

 

I got one for my 1996 at Autozone about a year and half ago, paid $125. Got one off Ebay for $20 for my 1995 about a year ago. No problems at all with the Ebay one. Checked codes last week, the 1996 is showing knock sensor code (no CEL though). I recommend getting a couple of them from Ebay, they are cheap and if you keep some in stock the, sum of cost of a bunch is still way less than regular store

 

OMG man. There are soooooooo many threads about ebay KS.

THEY WORK!!!!!!!!

SEARCH.

 

Just got my knock is was a $1. Well see how long it last

 

Im currently "using" one....although see my KS thread....

Whoa whoa whoa relax big boy, i'm not all savy like that, if you were so smart you would have included that, knock sensors are a "ghost code" and that you don't actually need to replace the sensor, it's just detecting something ELSE is wrong ie o2 sensors...

Put that in your search engine and smoke it!

 

I don't believe that's correct. It's a piezo crystal just like you find in cheap horn tweeters. That's why the resistance is so high.

 

Hell, my ebay special's still straight too after about a year of operation

 

Sorry, thats not true. My knock sensor DID actually go bad and it def was not a "ghost code"....trust me you will know when they go. You might want to take it easy and not be so aggressive. Esp with 125 post........just sayin....

And btw....my Ebay sensor for 19 shipped did the trick and fixed the problem.

 

wow, ill feel like a dumb ***. Paid $145 for mine from some bull**** parts house. autozones it $120.

 

Got my $12 eBay KS in the mail today. In the FSM, Nissan makes a big deal about not using a KS if it's been dropped. When I got it in the mail today wrapped in a single layer of thin bubble wrap in a paper envelope-- I wondered how many times it was dropped, thrown, etc. on it's way to me.

 

I'm waitng for my $12 KS to arrive in the mail today.

 

I bought one for like $15 about two years ago. It was from ebay but it is branded nissan and has not given me any problems.

 

I've has my $17 EBAY KS for 6 months. Code has stayed clear.

KS is basically a piezo microphone. It is tuned to produce the most signal at the frequency of the knock. This can be unique to each engine type. It is why the mounting area must be clean and the torque must be correct. If it hears funny things expect your performance to suffer as it retards ignition timing trying to stop the knock!
