What does the knock sensor in the 1997 q45 do?

The knock sensor in the 1997 Infiniti Q45 detects engine knock or pinging, which occurs when fuel ignites prematurely in the combustion chamber. By monitoring vibrations caused by this knocking, the sensor sends signals to the engine control unit (ECU). The ECU then adjusts the ignition timing and air-fuel mixture to optimize performance, enhance fuel efficiency, and prevent potential engine damage. This helps ensure smooth engine operation and longevity.
