Knocks when going over bumps on the road.

Lately I have been picking up knocks when going over bumps on the road. I have a rebuilt k20a2 with type-r pistons. I'm using the k20a3 knock sensor and a PRB ecu with k-pro.
Any idea on the differences between the k20a3 and k20a2 sensor? i.e. is it possible that there is a difference in voltage output between the two?

knocks registered from goging over a bump would be either bad wiring or somethign is loose somewhere and is banging and rattling.

Everything is secure. It might be the header banging against the sway bar, but i'm not sure.
Also, it doesn't do it over every bump. it's intermittent.

torn side motor mount fixed. No more random knocking so far.
Still curious about differences between a2 and a3 k sensors.

The A2 and A3 knock sensors have different part numbers. They will produce a similar output (electrically), so can be swapped. We have not tested the sensors to see if they produce different readings.

Awesome. I have a spare k20a2 and k20a3 knock sensor lying around. Maybe i'll conduct an experiment of my own if I can get a piezo speaker of the right freq. range.

hate to bring this back from the dead - but did anyone find out if there are any major differences between a2 & a3 knock sensors (& accord/tsx for that matter)?
-thanks
