ELECTRONIC FUEL INJECTION

IGNITION 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 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 plugs.

Ignition Coil / HT Lead Replacement

NOTE: Mark or note which ignition coil wire goes to
which cylinder and ignition coil post. 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.
1. Remove rear service panel to access the ignition coil.
2. Disconnect the ignition coil harness and remove the
high tension leads from the coil.
3. Remove the fastener retaining the ignition coil and
remove it from the vehicle. If replacing the high
tension lead(s), remove the other end of the lead(s)
from the spark plug.
4. Install the new ignition coil and/or high tension lead(s).
