IGNITION COIL IGNITION COIL TESTS
The ignition coil can be tested by using an ohm meter.
OPERATION OVERVIEW Use the following illustration and specification table to

The ignition coil q is used to provide high voltage to fire test the ignition coil resistance.
the spark plugs. When the ignition key is on, DC voltage
is present in the primary side of the ignition coil windings. TEST PIN CONNECTION Ω
During engine rotation, an AC pulse is created within the Primary Between 1 & 2 0.4 Ω
crankshaft position sensor for each passing tooth on the Between 2 & 3
flywheel’s encoder ring. The encoder ring missing tooth Secondary Between High Tension
creates an “interrupt” input signal, corresponding to (PTO) Lead Caps 7.0 k Ω ± 5%
specific crankshaft position. This signal serves as a
reference for the control of ignition timing. The ECU then Secondary Between High Tension 7.4 k Ω ± 5%
calculates the time interval between the consecutive (MAG) Lead Caps
pulses, and determines when to trigger the voltage spike
that induces the voltage from the primary to the Primary Test
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.

1. Remove engine access 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 11
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).
