are knock sensors between the b-series and h-series interchangeable? are obd1 and obd2 knock sensors interchangeable also? like will an obd2 knock sensor work on an obd1 engine and vice versa. I have an h23a1 in my 95 Accord, but the knock sensor that came with it was busted. So I disabled it in the ecu (moved resistors) and left the knock board in there. I want to get another knock sensor for it and can get a brand new obd2 gsr (b-series) knock sensor for $35. Please let me know what you think …

obd-1 and obd-2 knock sensors aren’t interchangeable.
