Default knock sensor

My SES light just came on. I hooked up the computer it said "Low voltage from knock sensor". Has anyone had the same issue? I erased the code and drove it more and the light didnt come back on yet? How hard is it to change the sensor?? Any advice would be greatly appreciated. The engine is a 99 T/A LS1 w/ M6 trans.
