6F2-2 IGNITION SYSTEM (FOR J20/H25 ENGINES)
General Description
The ignition system is a direct ignition system. It consists of the parts as described below and has an electronic
ignition control system.
• ECM (or PCM)
It detects the engine condition through the signals from the sensors, determines the most suitable ignition
timing and time for electricity to flow to the primary coil and sends a signal to the igniter (in ignition coil
assembly).
• Ignition coil assembly (including an igniter and an ignition coil)
The ignition coil assembly has a built-in igniter and ignition coil which turns ON and OFF the primary current
of the ignition coil according to the signal from ECM (or PCM). When the ignition coil primary current is
turned OFF, a high voltage is induced in the secondary wiring. One ignition coil is in charge of ignition of one
cylinder only.
• Spark plug and noise suppressor
• CMP sensor, TP sensor, ECT sensor and MAF sensor
For their details, refer to “Electronic Control System” in Section 6E1 or 6E2.
This ignition system does not have a distributor and high-tension cords but each cylinder has an ignition coil
assembly (igniter and ignition coil) and the secondary voltage which occurred in the ignition coil is sent to the
spark plug directly. Also, the signal(s) are sent from the CMP sensor to ECM (or PCM) so as to control each igni-
tion coil independently through the igniter (in ignition coil assembly).
