INSPECT IGNITION COIL (WITH IGNITER) AND
SPARK TEST

Check that the spark occurs.

(1)

Remove the ignition coils (with igniter). 
(see page 

IG–5

)

(2)

Remove the spark plugs.

(3)

Install the spark plugs to each ignition coil (with ig-
niter), and connect the ignition coil (with igniter) con-
nector.

(4)

Disconnect the 8 injector connectors.

(5)

Ground the spark plug.

(6)

Check that spark occurs while engine is being
cranked.

NOTICE:
To prevent gasoline from being injected out of injectors
during this test, crank the engine for no more than 5 to 10
seconds at a time.

SPARK TEST

Replace the crankshaft position sensor.

REPAIR WIRING BETWEEN IGNITION COIL 
AND ECM

Connect securely.

Check wiring between ignition switch
to ignition coil (with igniter).

(c)

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.

(d)

Check the spark plug for thread damage and insulator
damage.

If abnormal, replace the spark plug.

Recommended spark plug:

DENSO made

SK20R11

NGK made

IFR6A11

(e)

Adjust the spark plug electrode gap.
Electrode gap: 1.0 to 1.1 mm (0.039 to 0.043 in.)

(f)

Using a 16 mm plug wrench, install the spark plugs.
Torque: 17.5 N·m (180 kgf·cm, 13 ft·lbf)

(g)

Reinstall the ignition coils (with igniter).
