i think knock sensor sends signal in volts (high, low) and then ECU retards timing or not. Is there only 2 signals? and the timing is either retarted or not?

I know 0304 points to a problem with the Knock Sensor. Maybe there are other ones.
To check manually u need to use an ohmmeter which is pain in the ***.

How is it a pain? You unplug the connector, touch 2 pins with the leads and you're done. Either way the resistance means absolutely nothing. If you check the ECU and you have a code, get a new KS.
is there a posibility to have a broken KS without ECU giving code? (i know the light doesn't come on for KS) Can the KS be in a working state and maybe worn or something?
If the KS is broken there WILL be a code. It just won't show up unless you check the ECU yourself. Yes.
