Can a faulty knock sensor cause a vehicle to overheat?

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.
