knock sensor problems

I had the codes read on my 94 525i and the codes knock sensor curcuit 2 amd knock sensor curcuit 1 was showing. My question is what are these two codes? I know what a knock sensor is. Im just not sure what the codes mean. Is it that im running to low of a grade of gas and the system needs to be flushed? I really dont know and i need some answers or suggestios on what to. Thanks for any help or suggestions offered
