i was just looking through ebay (i know) and came upon this. it's supposedly a brand new in box oe part delphi as10148 knock sensor. not sure about the seller or if it's a genuine item or if delphi was/is an oe supplier of these to nissan but i figured i'd throw this up here since these normally sell for ~ $160 - $180 ish. hope this info is helpful to someone (and doesn't turn out to be junk, a scam or a bust).

 

i've used the cheap ebay knock sensors that sell under $20 bucks. It does take care of the ghost code but not really sure if it actually sends the correct info to the ecu or just mimics a functioning knock sensor.

 

i too have wondered the same thing, has anyone done tests on the oe / fleabay ks? any differences? voltage, resistance...things of this nature?

 

No ones cared enough to test it. It's cheap and it works and that's all that matters lol

 

I didn't know that there's an $8 KS. I bought a $40 one from ebay and it seems to be working fine. It's just a pain to replace it in a VE.

 

Will this part work in a 4th gen maxima? It says it will not work for the VQ on the listing.
