combustion noise sensor signal use To reduce the emission and improve the performance by changing the ignition timing. When the engine is accelerated the timing can change, you get a pinging noise. It senses that and adjusts the timing to compensate. They didn't have this in older engines without electronic ignitions and you had adjust the distributer to find a happy medium setting. It really imporves performance and power. Its not the same as an exhaust sensor that reads the unburnt fuel level and adjusts the fuel to lean out the mix. The exhaust sensor is more for the emission controls.

Where is the Knock Sensor located on a Chrysler Town and Country?
It is located on the side of the engine block. The purpose of the knock sensor is to retard engine timing When there is an engine noise. It is a rare case that one ever goes bad.
Emissions concerns on origins of engine noise?
fan , combustion, and exhaust
What In an automobile engine serves no purpose but with out it the engine will not work?
It is noise .
What in an automobile engine serves no purpose but without it the engine does not work?
noise
What in a car engine serves no purpose but without it the engine does not work?
The noise
Which are negative impacts that the internal combustion engine has had on society?
efficient travel and noise pollution
What in a automobile engine serves no purpose but without it the engine does not work?
Noise. Without noise, it can't work. Noise is in an engine, and without it does not work. Every engine has to make some kind of noise, internal or external, inside or outside the engine.
What in an automobile engine serves no purpose but without it the engine dose not work?
Noise !
What does the knock sensor make the engine do?
It retards / slows the engine timing up when it detects an engine knock / pining noise like bad fuel are valve noise.
Does the engine on a 2003 impala knock in the top of the motor if the knock sensor is bad?
The knock sensor just advances and retards the engine timing only. If there is a noise in the engine then you have engine are valve train problems. The knock sensor will not make the engine knock.
Can a bad 02 sensor cause your engine to make a noise?
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
What purpose does a muffler serve for my car?
A combustion engine is powered by a series of small explosions when fuel is ignited and burned to create energy. These explosions are noisy. The noise is directed through a "muffler," which does just that: muffles the noise so that the public is not overwhelmed by the constant noise of thousands of cars that pass by each day. The tailpipe allows exhaust to leave the engine after the fuel has been burned in an explosion, which powers the vehicle. The noise also leaves the tailpipe. The muffler "muffles" the noise.
