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’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.

Ignition Coil / HT Lead Replacement

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.

1. Remove the seats and engine 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).
