Overheating, yes.
Loss of antifreeze, no.
Yes, a faulty knock sensor can indirectly contribute to a vehicle overheating. The knock sensor detects engine knock or pinging and helps the engine control module adjust the ignition timing for optimal performance. If the sensor fails, the engine may experience incorrect timing adjustments, leading to inefficient combustion, increased heat generation, and ultimately overheating. However, overheating can also result from other issues, so it's essential to diagnose the problem thoroughly.
No it will not. The knock sensor is used to adjust the timing.
yes when it is not working properly
A faulty knock sensor is unlikely to directly cause your cooling fans to stay on. The knock sensor primarily detects engine knock or pinging to adjust ignition timing, while cooling fan operation is typically controlled by the engine's temperature sensors and the engine control unit (ECU). However, if the knock sensor is causing the engine to run inefficiently or overheating, it could indirectly lead to the cooling fans running more frequently. It's best to diagnose the cooling system separately to identify the actual cause.
No it will not.
the motor could pre-detonate or "knock" that can cause damage
Yep.
No it will not.
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.
No it will not cause it not to run.
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.
