IGNTION COIL

OPERATION OVERVIEW

The ignition coil is used to provide high voltage to fire the
spark plugs. When the ignition key is on, DC voltage is
present in the primary side of the ignition coil windings.
During engine rotation, an AC pulse is created within the
Crankshaft Position Sensor (CPS) for each passing tooth
on the flywheel. The two-tooth gap creates an "interrupt"
input signal, corresponding to specific crankshaft
position. This signal serves as a reference for the control
of ignition timing. The ECU then calculates the time
interval between the consecutive pulses, and determines
when to open the ground side of the primary coil circuit.
This triggers the voltage spike that induces the voltage
from the primary to the secondary coil windings to fire the
spark plugs.

IGNITION COIL TEST

The ignition coil can be tested by using an ohm meter.
Refer to the following illustrations and table to test the
ignition coil.
The ignition coil is located below the seat and upper RH
side panel.
