Cause they are junk? Next time go with GM or Chrysler
Problem with Knock Sensor circuit #1
Lifters dont really knock, they chatter. You may have a bigger problem.
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.
No, it will not cause the engine to knock.
You have another problem other then the knock sensor if the engine will not start and run. A knock sensor will not cause the engine not to run.
yes when it is not working properly
No it will not. The knock sensor is used to adjust the timing.
A knock probably means a bearing has already gone.
On Back of the Engine
I would say the Suzuki it's the fastest motorcycle in the world but the Enzo Ferrari is pretty good to I wouldn't knock either of them.
the motor could pre-detonate or "knock" that can cause damage
