IGNITION COIL

OPERATION OVERVIEW

q
The ignition coil
is used to provide high voltage to fire
the spark plug. When the ignition key is on, DC voltage is
present in primary side of the ignition coil windings.
During engine rotation, an AC pulse is created within the
crankshaft position sensor 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 trigger the voltage spike that induces the voltage from
the primary to the secondary coil windings to fire the
spark plug.

IGNITION COIL TESTS

The ignition coil can be tested by using an Ohm meter.
Use the following specification table and illustrations to
test the ignition coil.
