Low oil pressure can set a knock sensor fault code, but Low oil pressure will not damage the knock sensor. If the engine is noisy for any reason and not respond to reduced timing that a knock sensor has detected can set a code .
The knock sensors have the function to provide better performance and economy of the engines. In the Otto cycle, these sensors allow the ignition point to operate as close as possible to the ideal. In the Diesel cycle, sensors are closer to the knock limits.

Yes, it does. When knock sensor doesn't work, meaning no signal is fed to the engine computer, the engine will use the standard advance curve according to the mode the engine is running. It may not do anything at off-idle situations, but at full power acceleration, it may cause engine damage.
