Ion Sensor
Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias
voltage to the spark plug, which is amplified in the ignition coil internal
circuit and input to the PCM.

PCM
Purpose/Function
High-level driveability and lower fuel consumption have been realized by
controlling the appropriate engine conditions (fuel injection/ignition timing)
according to operation conditions.
Controls each output part based on the signal from each input part.
