(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, install the 6 spark plugs.
Torque: 18 N·m (180 kgf·cm, 13 ft·lbf)
(h) Reinstall the 6 ignition coil (See page IG-5 ).
3. INSPECT IGNITION COILS (WITH IGNITERS)
(See step 1.)
4. INSPECT CAMSHAFT POSITION SENSORS
(a) Remove the V-bank cover.
(b) Remove the air cleaner hose w/ resonator.
(c) Disconnect the sensor connectors.
(d) Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
Cold 835 - 1,400
Ω
Hot 1,060 - 1,645
Ω
If the resistance is not as specified, replace the sensor.
(e)
Reconnect the sensor connectors.
(f) Reinstall the air cleaner hose w/ resonator.
(g) Reinstall the V-bank cover.
5. INSPECT CRANKSHAFT POSITION SENSOR
(a) Remove the sensor (See page IG-9 ).
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance:
Cold 1,630 - 2,740
Ω
Hot 2,065 - 3,225
Ω
If the resistance is not as specified, replace the sensor.
(c)
Reinstall the sensor (See page IG-9 ).
