One KS is installed on each head under intake manifold. See Fig 1 . 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.
