knock sensor is a very sensitive small microphone usually on the engine block or sum times on the cylinder head , it listens for any pre detonation going on in your engine . pre detonation is nasty early combustion you dont want, if you get pre det it causes a pre knock sound which the knock sensor microphone detects.
your probly not getting pre detonation but thats what the sensor does 8)
"sensor 1 circuit" means the ecu has detected it cannot make connection to the sensor, the sensor could be dead or you could have a wiring issue to the sensor IE chaffed wire, bad connection at the plug ect.
