4. CHECK AIR INLET LINE
(a) Disconnect the air inlet line hose from the charcoal
canister.
(b) Check that air can flow freely into the air inlet line.
If air cannot flow freely into the air inlet line, repair or
replace it.
(c) Reconnect the air inlet line hose to the charcoal
canister.
5. VISUALLY INSPECT HOSES, CONNECTORS AND
GASKETS
(a) Check for cracks, leaks or damage.
HINT:
Removal or problems with the engine oil dipstick, oil
filler cap, PCV hose and other components may
cause the engine to run improperly. Disconnection,
looseness or cracks in the parts of the air induction
system between the throttle body and cylinder head
will allow air suction and cause the engine to run
improperly.
If necessary, replace any damaged parts.

ON-VEHICLE INSPECTION
NOTICE:
In this section, the terms "cold" and "hot" refer to the
temperature of the coils. "Cold" means approximately -
10
C (14F) to 50C (122F). "Hot" means approximately
50
C (122F) to 100C (212F).
1. INSPECT IGNITION COIL ASSEMBLY
(a) Check for DTCs.
NOTICE:
If any DTC is present, perform troubleshooting
in accordance with the procedures for that DTC.
(b) Remove the ignition coil assembly and spark plug.
(See page IG-8).
(c) Check that sparks occur.
(1) Disconnect the 6 fuel injector connectors.
(2) Install the spark plugs to each ignition coil, and
connect the ignition coil connectors.
(3) Ground the spark plugs.
(4) Check if a spark occurs at each spark plug
while the engine is being cranked.
NOTICE:
• Be sure to ground the spark plugs when
checking.
• Replace the ignition coil if it receives an
impact.
• Do not crank the engine for more than 2
seconds.
(d) Perform the spark test according to the flowchart
below.
(1) Check that the ignition coil connector is
securely connected.
Result
(2) Perform a spark test on each ignition coil.
1. Replace the ignition coil with a normal one.
2. Perform the spark test again.

(4) Check the power supply to the ignition coil.
1. Turn the ignition switch to the ON position.
2. Check that there is battery voltage at the
ignition coil positive (+) terminal.
Result
(5) Measure the resistance of the crankshaft
position sensor (See page ES-514).
Result
(6) Check the IGT signal from the ECM (See page

(e) Using a 16 mm (0.63 in.) plug wrench, install the
spark plugs.
Torque: 18 N*m (184 kgf*cm, 13 ft.*lbf)
(f) Connect the 6 fuel injector connectors.
(g) Install the ignition coil assembly (See page IG-10).
2. INSPECT SPARK PLUG
NOTICE:
• Never use a wire brush for cleaning.
• Never attempt to adjust the electrode gap on a
used spark plug.
(a) Check the electrode.
(1) Using a megohmmeter, measure the insulation
resistance.
Standard insulation resistance:
10 M
or higher
HINT:
• If the result is 10 M
or less, clean the plug
and measure the resistance again.
• If a megohmmeter is not available, perform
the following simple inspection instead.
(b) Alternative inspection method:
(1) Quickly accelerate the engine to 4000 rpm 5
times.

(2) Remove the spark plugs.
(3) Visually check the spark plug.
If the electrode is dry, the spark plug is
functioning properly. If the electrode is damp,
proceed to the next step.
(c) Check the spark plug for any damage to its threads
and insulator. If there is damage, replace the spark
plug.
Recommended spark plug
NOTICE:
Use only the listed spark plug or equivalent to
ensure engine performance and smooth
driveability.
(d) Check the spark plug electrode gap.
Maximum electrode gap for used spark plug:
1.4 mm (0.055 in.)
If the gap is greater than the maximum, replace the
spark plug.
Electrode gap for new spark plug:
1.0 to 1.1 mm (0.039 to 0.043 in.)
(e) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the
electrode with a spark plug cleaner and then dry it.
Standard air pressure:
588 kPa (6 kgf*cm
2, 85 psi)
Standard duration:
20 seconds or less
HINT:
Only use the spark plug cleaner when the electrode
is free of oil. If the electrode has traces of oil, use
gasoline to clean off the oil before using the spark
plug cleaner.
(f) Install the ignition coil assembly and spark plug.
(See page IG-10).
