Does anyone know if all GM knock sensors are infact the same? I have seen some that look identical on votrec 4.3l, 5.7l and most other GM motors.

I am looking for a new one, but they seen to be super expensive.

Thanks

A quote from an article on the TT website.

"The sensor in the turbo 3.8L has a resonant frequency of 6 KHz. "

That is good to know, but no parts guy will be able to tell me what is what. Or will they?

Does anyone have a new knock sensor for sale?
 
GM PART # 10456287
ACDELCO Part # 213325

You should be able to find it for $35-$45...
And it does appear to have more applications than just the LC2, icluding the LT1 as DD wrote about and maybe the TPI and possible the LS series.(it's just listing a year range from 85-2002)

You know...it's function is critical and certainly not worth saving $10 here or there. Piece of mind sometimes isn't cheap....
 
Thank you WS6. I will look the part up when i am home once more. Thanks again.
