When the sensor goes out, the engine starts to shake violently, after running tit fo a few minutes. And you will also expend more in gas!!, the motor will run,, but uses more gas due bad timing signal... Jesus S. --------------------
Nothing really happens unless you are using VERY low grade gasoline. First, if its bad get it replaced by a service tech. Its hard to replace for a novice and you waste money because your fuel mileage goes down. Running my vehicle with a bad knock sensor, I've gone from 32 MPG to 25 MPG. I could have paid for a new sensor several times over by now.
Its possible that the engine could "shake violently" but use a higher octane gasoline to prevent predetonation until you get it fixed.

What happens when knock sensor goes out on a 1994 Nissan Altima?
The knock sensor advances the timing to optimize fuel efficiency. When it goes out, your gas mileage goes down.
What does a car do when the knock sensor is bad?
The knock sensor retards the engine timing when there is a knock or ping detected. This will make the car a little sluggish. It is rare that the knock sensor goes bad.
Does a knock sensor ECM error mean that sensor is bad or that the sensor is just reporting a knock in the engine?
The sensor is bad. A properly-functioning knock sensor allows the ECM to advance timing until it senses a knock. It then retards timing until the knock just barely goes away allowing for optimal gas mileage.
When the knock sensor is disconnected what happen to the car?
Nothing will happen to the car if you disconnect the knock sensor. It just will not detect a problem if there happens to be one.

Where is the knock sensor located on a 95 Chevy blazer?
The knock sensors yes there are two are located on either side of the motor (4.3LTR Vortec) below the heads in the center area of the engine block.

How can you tell if your knock sensor is bad?
Not much goes wrong with them! if your car is pinging under load this may be a bad knock sensor, but if you tap the block with a small hammer & the idol seems to change or the timing wanders this is the knock sensor failing. if the idol doesn't change this is a bigger issue

We need to know what engine you have to answer that.
What is knock sensor on Honda s2000?
A knock sensor detects engine knock in the motor(aka pinging, detonation, or uncontrolled explosions. it basically means the motor is about to blow up or potentially could.) the second part to a knock sensor is that it keeps the ignition timing as advanced as possible to make the most power without making engine knock. So if you have a bad knock sensor or have a check engine light form a knock sensor your car will be slower. this is when your car goes into LIMP mode which is basically a preset running condition which is safe for the motor.
