NOTICE:
ºColdº and ºHotº in following sentences express the tem-
perature of the coils themselves. ºColdº is from -10°C
(14°F) to 50°C (122°F) and ºHotº is from 50°C (122°F) to
100°C (212°F).
1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Disconnect the high-tension cord from the spark
plug.
(2) Remove the spark plugs.
(3) Install the spark plugs to the high-tension cord.
(4) Ground the spark plug.
(5) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors dur-
ing this test, crank the engine for no more than 5 - 10 se-
conds at time. If the spark done not occur, do the test as fol-
lows:

2. INSPECT HIGH-TENSION CORDS
(a) Disconnect the high-tension cords from the spark plugs.
(1) Disconnect the high-tension cords at the rubber
boot. Do not pull on the cords.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
(2) Disconnect the high-tension cords from the clamp.
(b) Disconnect the high-tension cords from the ignition coils.
(1) Using a screwdriver, lift up the lock claw and discon-
nect the holder from the ignition coils.
(2) Disconnect the high-tension cord at the grommet.
(3) Do not pull on the cord.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside. Do not wipe any of the oil from the grommet after the
high-tension cord is disconnected.
(c) Reconnect the high-tension cords to the ignition coils.
Maximum resistance: 25 kW per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high-tension cord.
(d) Reinstall the high-tension cords.
(1) Assemble the holder and grommet.
(2) Align the spline of the ignition coil with the spline of
the holder, and push in the cord.
NOTICE:
Check that the holder is correctly installed to the grommet
and distributor cap as shown in the illustration.
(3) Check that the lock claw of the holder is engaged by
lightly pulling the holder.
(4) Connect the high-tension cords to the clamp.
(e) Reconnect high-tension cords to spark plugs.

3. INSPECT SPARK PLUGS
(a) Disconnect high-tension cords from spark plugs.
(b) Using a 16 mm plug wrench, remove the spark plug.
(c) Using a spark plug cleaner or wire brush, clean the spark
plug.
If the electrode has traces of wet carbon, allow it to dry and then
clean with a spark plug cleaner.
Air pressure:
Below 588 kPa (6 kgf/cm
2, 85 psi)
Duration: 20 seconds or less
HINT:
If there are traces of oil, remove it with gasoline before using the
spark plug cleaner.
(d) Visually checkthe spark plug for thread damage and insu-
lator damage.
If abnormal, replace the spark plug.
Recommended spark plug:
DENSOK16TR11
NGKBKR5EKB11
(e) Inspect the electrode gap.
Correct electrode gap: 1.1 mm (0.043 in.)
(f) Using a 16 mm plug wrench, remove the spark plug.
Torque: 18 N´m (180 kgf´cm, 13 ft´lbf)
(g) Reconnect the high-tension cords from the ignition coils.

4. INSPCT IGNITION COILS WITH IGNITER
(a) Disconnect the high-tension cords from the ignition coil.
(b) Disconnect ignition coils connector.
(c) Inspect the primary coil resistance.
Using an ohmmeter, measure the resistance between the
positive (+) and negative (-) terminals.
Primary coil resistance :
Cold0.67 - 1.05 W
Hot0.85 - 1.23 W
If the resistance is not as specified, replace the ignition coil.
(d) Remove ignition coils.
(e) Inspect the secondary coil resistance.
Using an ohmmeter, measure the resistance between the
positive (+) and high-tension terminal.
Secondary coil resistance :
Cold9.3 - 16.0 kW
Hot11.7 - 18.8 kW
If the resistance is not as specified, replace the ignition coil.
(f) Reinstall ignition coils
(g) Reconnect ignition coil connectors.
(h) Reconnect high-tension cords from ignition coils.
5. INSPECT CAMSHAFT POSITION SENSOR
(a) Disconnect camshaft position sensor connector.
(b) Inspect camshaft position sensor resistance.
Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
Cold985 - 1,600 W
Hot1,265 - 1,890 W

6. INSPECT CRANKSHAFT POSITION SENSOR
(a) Disconnect crankshaft position sensor connector.
(b) Inspect crankshaft position sensor resistance.
Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
Cold985 - 1,600 W
Hot1,265 - 1,890 W
If the resistance is not as specified, replace the crankshaft posi-
tion sensor.
