Hall Sending Unit

The distributor with its Hall sending unit is located at the left rear of the engine. It sends just 1 broad signal per distributor shaft rotation, just before ignition TDC on No. 1 cylinder.

This signal only permits the signal of 60° BTDC on No. 1 cylinder to be accepted as the reference mark signal in the control unit.
