No. Worst case senario with a bad knock sensor is check engine light, and bad fuel economy. Also spark knock, which if not taken care of can cause excessive heat to build in the engine and cause premature failure.
In most cases corrosion will cause a knock sensor to go bad. The knock sensor can also be shorted out by an electrical surge.
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.
It could.
Crank angle sensor or coolant temprature sensor are the two favourites that will cause a non start

Yep.
the motor could pre-detonate or "knock" that can cause damage
No all it is is basically a microphone to monitor for noise-nothing to do with the engine running.
I have a 240 and with the knock sensor unplugged it will still start so I would have to say no.
Perhaps--unless the sensor itself is bad.
A bad crankshaft sensor on a 2.3 Ford may cause the car to not start. A bad crankshaft sensor can crank, just not start.
yes, it is protecting the motor from damage.
If you run your rig with a bad knock sensor the computer will not be able to tell if or when your engine starts to knock (such as a rod knocking). That is if it isn't already cause the sensor is there for insurance. Make sure the sensor is bad and if so have it replaced asap. It is an expensive job cause you have to remove the intake to get to them (some engines have two under the intake). willyray3
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.
Yes it can hurt your engine to drive with a bad knock sensor. The knock sensor should be replaced as soon as possible.
