6F-2 IGNITION SYSTEM
GENERAL DESCRIPTION
The ignition system used for this vehicle has an electronic ignition control system and consists of the following
parts.
D ECM
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.
D Igniter
It turns ON and OFF the primary current of the ignition coil according to the signal from ECM.
D Ignition coil
When the ignition coil primary current is turned OFF, a high voltage is induced in the secondary winding.
D Distributor
It distributes a high voltage current to each plug.
D High-tension cords, spark plugs and noise suppressor.
D CMP sensor (Camshaft position Sensor)
Located in the distributor, it converts the crank angle into voltage variation and sends it to ECM. For its details,
refer to SECTION 6E.
D TP sensor, ECT sensor and MAP sensor
For their details, refer to SECTION 6E.
