NOTICE:
ºColdº and ºHotº in these sentences express the tempera-
ture 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

1. INSPECT IGNITER AND SPARK TEST
Check that the spark occurs.
(1) Remove the ignition coil. (See page IG-6)
(2) Remove the spark plug.
(3) Install the spark plug to the ignition coil, and connect
the ignition coil connecter.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being
cranked.
NOTICE:
To prevent excess fuel being injected from the injectors
during this test, do not crank the engine for more than 5 -
10 seconds at a time.
If a spark does not occur, do the test as follows:

2. INSPECT SPARK PLUGS
NOTICE:

Never use a wire brush for cleaning.

Never attempt to adjust the electrode gap on used a
spark plug.

Spark plugs should be replaced every 100,000 km
(60,000 miles).
(a) Remove the ignition coils assemblies.
(See page IG-6)
(b) Inspect the electrode.
Using a megger (insulation resistance meter), measure
the insulation resistance.
Standard correct insulation resistance:
10 MW or more
If the resistance is less than specified, proceed to step (c).
HINT:
If a megger is not available, the following simple method of in-
spection provides fairly accurate results.
Simple Method:

Quickly race the engine 5 times to 4,000 rpm.

Remove the spark plug.

Visually check the spark plug.
If the electrode is dry ... OK
If the electrode is wet ... Proceed to step (d).

Reinstall the spark plug.
(c) Using a 16 mm plug wrench, remove the 6 spark plugs.
(d) Visually check the spark plug for thread damage and insu-
lator damage.
If abnormal, replace the spark plug.
Recommended spark plug:
DENSO madePK20R11
NGK madeBKR6EP11
(e) Inspect the electrode gap.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE:
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip. Never attempt
to adjust the gap on the used plug.

(f) Clean the spark plugs.
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.
(g) Using a 16 mm plug wrench, reinstall the 6 spark plugs.
Torque: 18 N´m (180 kgf´cm, 13 ft´lbf)
(h) Reinstall the ignition coils assemblies.
(See page IG-7)
3. INSPECT IGNITION COILS
(a) Remove the No.3 timing belt cover.
(b) Disconnect the ignition coil connectors.
(c) Using an ohmmeter, measure the resistance between the
terminals.
Primary coil resistance:
Cold0.54 - 0.84 W
Hot0.68 - 0.98 W
If the resistance is not as specified, replace the ignition coil.
(d) Reconnect the ignition coil connectors.
(e) Reinstall the No.3 timing belt cover.
4. INSPECT CAMSHAFT POSITION SENSORS
(a) Disconnect the camshaft position sensor connectors.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
Cold835 - 1,400 W
Hot1,060 - 1,645 W
If the resistance is not as specified, replace the camshaft posi-
tion sensor.

(c) Reconnect the camshaft position sensor connectors.
5. INSPECT CRANKSHAFT POSITION SENSOR
(a) Remove the No.2 air tube for the CAC.
(b) Disconnect the crankshaft position sensor connector.
(c) Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
Cold835 - 1,400 W
Hot1,060 - 1,645 W
If the resistance is not as specified, replace the sensor.
(d) Reconnect the crankshaft position sensor connector.
(e) Reinstall the No.2 air tube for the CAC.
