I did read it. Just because that's what they tell their mechanics what is going on, doesn't mean it is 100% technically correct.
In an interesting side note: There were some Subarus built with 'overactive' knock sensors. The recommended fix from the factory: a small amount of teflon tape on the threads to insulate it from the knock vibrations... On the flip side, some of the earliest US WRXs were shipped with almost deaf knock sensors. The result? About an extra 30hp and all those great reviews of the WRX (and that 5.4 second 0-60 time) and then the motors eating themselves alive after a while.
