IGNITION COIL

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 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.
