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

Knock Sensor (KS)

One KS is installed on each head under intake manifold. Using 2 sensors makes it possible for PCM to sense cylinder knock more accurately. KS I is located on right cylinder bank and monitors cylinders No. 1, 2 and 3. KS II is located on left cylinder bank and monitors cylinders No. 4, 5 and 6. See DETONATION RETARD OPERATION under IGNITION CONTROL  under IGNITION SYSTEM.
