(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.
