Ignition Spark TestS6RW0D1804004
1) Remove air cleaner assembly with air intake pipe.
2) Disconnect all injector couplers from injectors.
WARNING!
Without disconnection of injector couplers,
combustible gas may come out from spark
plug holes during this test and may get
ignited in engine room.

3) Remove spark plug and check it for condition and
type referring to “Spark Plug Inspection”.
4) If OK, connect ignition coil coupler to ignition coil
assembly and connect spark plug to ignition coil
assembly or high-tension cord. Ground spark plug.5) Crank engine and check if each spark plug sparks.
6) If no spark is emitted, inspect the related parts as
described in “Ignition System Symptom Diagnosis”.
Repair Instructions
High-Tension Cord Removal and InstallationS6RW0D1806001
Removal
1) Remove air cleaner assembly with air intake pipe
and cylinder head upper cover.
2) Disconnect No.1 cylinder (2) and No.3 cylinder (3)
high-tension cords from ignition coil assemblies (1)
while gripping each cap.
3) Pull out high-tension cords from spark plugs while
gripping each cap.
CAUTION!
• Removal of high-tension cords together
with clamps will be recommended so as
not to damage their inside wire (resistive
conductor).
• For the same reason, pull out each
connection by gripping cap portion.

Installation
1) Install No.1 cylinder (2) and No.3 cylinder (3) high-
tension cords to spark plugs and ignition coil
assemblies (1) while gripping each cap.
CAUTION!
• Never attempt to use metal conductor
high-tension cords as replacing parts.
• Insert each cap portion fully when
installing high-tension cords.

High-Tension Cord InspectionS6RW0D1806002
Measure resistance of high-tension cord (1) by using
ohmmeter.
If resistance exceeds specification, replace high-tension
cord(s).
High-tension cord resistance
No.1 cylinder high-tension cord resistance: 1.4 – 4.0
kΩ
No.3 cylinder high-tension cord resistance: 0.6 – 2.0
kΩ
Spark Plug Removal and InstallationS6RW0D1806003
Removal
1) Remove air cleaner assembly with air intake pipe
and cylinder head upper cover.
2) Pull out high-tension cords by gripping their caps
and then remove ignition coil assemblies referring to
“Ignition Coil Assembly (Including Ignitor) Removal
and Installation”.
3) Remove spark plugs.
Installation
1) Install spark plugs and tighten them to specified
torque.
Tightening torque
Spark plug: 25 N·m (2.5 kgf-m, 18.0 lb-ft)
2) Install ignition coil assemblies referring to “Ignition
Coil Assembly (Including Ignitor) Removal and
Installation”.
3) Install high-tension cords securely by gripping their
caps.
4) Install cylinder head upper cover and air cleaner
assembly with air intake pipe.
Spark Plug InspectionS6RW0D1806004
CAUTION!
• When servicing the iridium / platinum
spark plugs (slender center electrode type
plugs), do not touch the center electrode
to avoid damage to it. The electrode is not
strong enough against mechanical force
as it is slender and its material is not
mechanically tough.
• Do not clean or adjust gap for the iridium /
platinum spark plugs.

Inspect spark plug for:
• Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found for nickel spark plugs, adjust
air gap, clean with spark plug cleaner or replace it with
specified new plug.
For iridium / platinum spark plugs, replace it with new
plug.
Spark plug air gap
“a”
: 1.0 – 1.1 mm (0.040 – 0.043 in.)
Spark plug type
NGK: BKR6E-11 (Nickel) / IFR6J11 (Iridium)
DENSO: K20PR-U11 (Nickel)
NOTE
NGK IFR6J11 is highly recommended for
better engine starting performance under –25
°C (–13 °F).
