Electronic Ignition System

The Hall Effect sensor in the distributor uses a shutter window wheel, mounted on the distributor shaft. The shutter blades pass in and out of the air gap of the Hall Effect sensor, resulting in signal pulses. There is one shutter window for each engine cylinder.

Signals from distributor Hall Effect sensor are sent to the ECU/ECM. The ECU/ECM sends a switching voltage signal to the ignition coil primary circuit to discharge secondary spark voltage.
