Knock sensors detect abnormal vibrations in the engine. The system is designed to reduce spark knock during periods of heavy detonation. Knock sensors produce AC output voltage which increases with the severity of the knock. The signal is fed into the PCM and the timing is retarded to compensate for the severe detonation.

What is the function of a knock sensor on a 1991 4.3 s10?
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.
What is the function of the knock sensor on the Lexus ES 300?
The knock sensor allows the computer to adjust the engine timing for maximum advance and fuel economy.
What is the function of a knock sensor on a 2000 mercury villager?
the knock sensor monitors preignition,spark knock and sends signal to pcm,pcm responds by adjusting ignition timing and fuel timing until knock is gone.
What is the function of an detonation knock sensor?
The knock sensor detects spark knock or ping and sends a signal to the vehicles putor. The putor takes that information and retards timing in an attempt to eliminate the ping.

What is the function of a crankcase sensor in a 2005 Audi A4 1.8T Cabriolet do?
There's no such thing as a crankcase sensor as engine sensors are normally defined by their function rather than what they are mounted to. What you are probably referring to is the knock sensor which is usually mounted on the side of the engine block. The knock sensor monitors detonation/pinging/pre-ignition and is used by the engine management system to offset the ignition timing.
