Knock sensor

O.K. yes I added an additive that said it increases the octane by 9. I use premium at 91 octane and when I added the additivie according to the bottle added 9 so that put my ocatne at 100 91+9=100.
The engine light came on right after I added the additive and when I checked it the knock sensor code 52 started.
The car runs real good and I need to know if I don't fix this code will I do any damage to the engine?I thought the higher the octane the better the car would run.
I found the sensor on the block by the intake and unplugged it. After runnig the car for a short period the engine light came back on giving me the same code. Does that mean the rear knock sensor is bad or is there a short somewhere.
