I think it's a DOHC thing. From what I've seen SOHC Honda's don't have knock sensors but the DOHC ones do.

As far as I know, the D16Y8 is the only D-series to have a knock sensor.

you'll notice the engines that have knock sensors have higher compression ratios..obviously for the detonation/pinging that usually occurs with the higher compressions..
