Hello again,
No they will not. What a knock sensor does is detects detonation, when the air fuel mixture in your combustion chamber self ignites without the spark plug igniting it. This usually happens when the piston is still on the upward compression stroke and can be catastrophic to your engine's internal components. Once the knock sensor detects detonation, it sends a signal to your vehicle's Power-train Control Module [PCM] or "computer", which will retard your vehicle's ignition timing, pulling it away from detonation. Please ask this question again separately, like a new question, for archival reasons, and we can answer why you are having a high idle for you.
Thanks,
Alex
