replacing knock sensor.

There was another thread about whether using a knock sensor from another Honda engine "works" on an S2000 even if it fits.
The knock sensor is tuned to react to the specific frequency created by a knock and then it sends a signal to the ECU--- unanswered question is whether the frequency created by a knock in a Honda Odyssey V6 the same frequency as in our S2000s 4 cylinder--if it isn't, thesensor won't react to it and it wont send a signal when a knock occurs.
While other manufacturers may make folks pay extra for parts for their speciality vehicles, my take is that Honda wouldn't have made (and have dealers stock) a separate knock sensor just for a S2000 vs their other cars unless there was something different about it.
So, even though it physically fits and uses the same connector, until someone can show the Odyssey sensor reads and reacts to the same frequency, if I need one, I'll bite the bullet and pay the extra for the S2000 version--- the knock sensor is a critical piece in ensuring longivity in our engines.

Is there away to test this? If someone can send me a broken S2000 sensor, maybe I can test it on an oscilloscope and compare the voltage generated by it to one for an Odyssey.

Yes.
All i am stating is what DID work for me. Its up to you if you want to use it. Clearly, i am using this until i get my s2000 one in the mail. From there... i am going to test them.
And i will update if anything happens.

That would be great if you could test it!! On the earlier thread, no one actually did.
I don't know how nor have the equipment to do it.
I like the idea of using the cheaper part if it works the same--- I was just trying to say that physical appearance and the same electrical connection doesn't necessarily mean if functions the same and if it doesn't detect a knock when it should, significant engine damage can occur over time.
Looking forward to a definitive answer!
Thanks!

Ballade sports has a replacement for far less than Honda. I believe they were able to source the OEM and get it on their own, since Honda themselves don't manufacture the part.

I just replaced my knock sensor.
I positioned the socket and extension from below and then attached my 1/2 driver from above to remove it.
Then installed the new one from below using the deep socket and 1/2 to 3/8 reducer and tightened it from below.
Thanks for the writeup.

Since it hasn't been mentioned yet...what's the torque spec??
