Electronic Ignition System

Hall-Effect sensors are used to detect position of a rotating shutter wheel. As each segment of the metal shutter wheel passes between the Hall-Effect sensor and a magnet, a change in current occurs. The Hall-Effect sensor responds to the change in magnetic field by switching a transistor on or off.

This signal is used by PCM to detect the position of each cylinder or TDC of cylinder No. 1. The PCM delivers ignition signals to the ignitor to control ignition. Ignitor triggers ignition coil.
