IGNITION COIL
Operation Overview
The ignition coil
is used to provide high voltage to fire
1
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 for each passing tooth on the
flywheel's encoder ring. The encoder ring missing tooth
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 plugs.

NOTE: The engine will misfire if the spark plug
wires are installed incorrectly. The spark plug wires
are marked with PTO and MAG from the factory and
should be installed to the corresponding cylinder
and ignition coil post.
