Player can ask HK-47 about the Sonic Imprint Sensor even if they don't have it.

Apparently the player is able to ask HK about the Sonic Imprint Sensor even if they failed to pick it up on Peragus. Looking at the DLG, it looks like it should be working as intended. There's a conditional that appears to be checking a global being set to 1. There is speculation TSLRCM changed it so that you could access that avenue without the sensor, which would presumably mean a script is setting the global regardless, most likely on Peragus or afterwards on the Hawk.

Edit: Speculation that the global could be set on examining the container the sensor is in without looting it.
