not pass the magnetic resistance element and the
resistance decreases. The inlet camshaft position
sensor converts this change in resistance of the
magnetic resistance element to a 5 V pulse signal
and outputs it to engine-ECU.
DETONATION SENSOR
A detonation sensor is installed on the inlet side of
the cylinder block. Detonation sensor uses the piezo-
electric element to convert the vibration of the cylin-
der block generated when engine is in operation to
minute voltage that is output to engine-ECU.
Engine-ECU uses the minute output voltage from the
detonation sensor filtered through the cylinder
block's natural frequency to detect knocking, and
compensates the ignition timing lag according to the
strength of the knocking.
