Need to know what engine it has.
The function of the knock sensor ob a sensor on a 1991 4.3 s10 is to provide the computer the position of the crank shaft to give it the right information to get correct timing. That would be the crank position sensor. The knock sensor monitors the engine for spark knock (ping) so the ECM (Engine Control Module) can retard the timing to eliminate it.

The cam sensor is the distributor.
