Default knock sensor code

Last night my ses light came on. Plugged in a scanner and it says its a knock sensor. What can cause this? how can i fix it? I have tsp duals my first assumption was my exhaust hitting the floorboards but I have had the exhaust for a couple months now and it just threw the code now. I had the car tuned by rpm a few weeks ago.

Turned the light off today drove around, the car ran perfectly fine. No issues or anything. The exhuast occasionally hits the floorboard on wot shifts but i didnt do any of that today and the light came back. The spark plugs looked good and it idled like nothing ever happened. Ideas?

Could also be the harness going bad. I'm chasing the same issue and it's a pain in the ***
