IGNITION COIL

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

The ignition coil can be tested by using an Ohm meter.

Use the following specification table and illustrations to

test the ignition coil.
