Ignition System - 4-CYL: Description

Two variations of electronic ignition are used with the 1.9L 4-cylinder engine, both making use of a Nippondenso distributor.

California models feature a computer, in addition to other ignition components. The computer is a part of the computerized engine control system. Federal models incorporate an engine speed sensor into the system, but have no computer.

The distributor has both vacuum and centrifugal advance mechanisms. It also houses a reluctor, stator, magnet set, and a pick-up coil and control module assembly. See Fig 1 and Figure. The system makes use of a conventional ignition coil with positive, negative, and secondary terminals.
