July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Knock Sensor (KS)

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2000 Nissan Xterra, 2000 Nissan Sentra, 2000 Nissan Quest, 2000 Nissan Pathfinder, and 2000 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Basic ignition timing is preprogrammed. Knock sensor detects engine knocking, converts knocking vibration into voltage signal and transmits signal to ECM. Information is used by ECM to adjust ignition timing accordingly to eliminate detonation.
