Sorry for taking so long. That code is indeed for the knock sensor, but it doesn't say what type of problem it is. The way I'd approach this would be to connect a scanner to view live data and see what the Engine Computer is seeing. If there s no activity from the sensor, the best suspect is a broken wire going to the it. If there is a lot of activity, especially at a specific engine speed, a good suspect is a stretched timing chain slapping against the cover. Your engine uses a timing belt, so the next thing would be to look for any other metal parts that can clatter or rattle. Look at the valve train in particular, and even idler pulleys for the timing belt and belt-driven generator and power steering pump.
