An engine may have one or more knock or detonations sensors in the block. The sensors use piezoelectric materials to detect vibrations in the block. If a certain vibration known to be caused by pre-ignition is detected, the ECU can take action, such as reducing ignition timing advance.

What is knock sensor?
A knock sensor is a device that senses detonation. Detonation occurs in the engine when the fuel begins to burn prematurely; it can cause substantial damage to the engine.

What is a Renault scenic knock sensor?
A knock sensor is a sensor inside an engine that detects detonation of fuel prior to the spark plug igniting the full during the cycles of the engines. Detonation at the wrong time can cause significant harm to an engine since it will cause the piston where the detonation occurred to be pushed down at the incorrect time. This can result in a catastrophic breakdown of the whole engine. A knock sensor monitors irregular detonation and will automatically retard or advance the timing of the engine to ensure that serious damage is not caused to the motor.
Will a knock sensor make it not to idle?
The knock sensor has no effect on idle. It has no effect at all unless it is triggered by detonation. It is a passive device.
How does a missile detonate?
Missiles can detonate through various methods, such as impact detonation upon striking a target, proximity detonation triggered by a sensor detecting the target's presence, or command detonation initiated by a remote operator. The specific detonation mechanism depends on the missile's design and intended use.
What does a knock sensor do on a 4.9 6-cylinder f-250 engine?
the knock sensor detects pre detonation ans adjusts the timing to compensate
What is knock sensor 1 circuit malfunction bank 1 or 1 sensor mean?
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.

Where is a detonation sensor on a Nissan exa CA18 engine?
On the side of the engine close to the firewall. Near The Oil Pump
What is the purpose of a knock sensor in 2003 jeep wrangler?
It is there to detect detonation or ( knocking ) and the information is used to adjust timing by the pcm.
What is the purpose of a knock sensor on 2002 Mercury Villager?
It detects detonation in the combustion chamber(s), then adjusts the engine timing to compensate.
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.
Where is the knock sensor located on a 1997 ford explorer?
The Knock Sensor (KS) is mounted on the engine, above the alternator and used to sense engine detonation. The knock sensor is a frequency amplifier with the sensor designed to resonate at approximately the same frequency as the engine knock. This allows relatively large signals to be sent to the Electronic Control Assembly (ECA) without electrical amplification and with a relatively small sensor. The ECA uses this information to alter the ignition timing to optimize ignition timing while reducing the occurrence of spark detonation.
