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
(212°F).
1. INSPECT IGNITION COIL (WITH IGNITER) AND
SPARK TEST
Check that the spark occurs.
(1) Remove the ignition coils (with igniter) (See page
IG±6).
(2) Using a 16 mm (0.63 in.) plug wrench, remove the
spark plugs.
(3) Install the spark plugs to each ignition coils (with ig-
niter), and connect the ignition coil connectors.
(4) Disconnect the 4 injector connectors.
(5) Ground the spark plugs.
(6) Check 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.

CHECK POWER SUPPLY TO IGNITION COIL (WITH
SENSOR (See step 3)
SPARK TEST
Replace the crankshaft position sensor.
CHECK RESISTANCE OF CAMSHAFT POSITION
1. Turn ignition switch to ON.
2. Check that there is battery voltage at ignition coil positive (+)
terminal.

TRY ANOTHER IGNITION COIL (WITH IGNITER)
Replace the camshaft position sensor. Connect securely.
Check wiring between ignition switch
to ignition coil (with igniter).
Check wiring between ECM and ignition
coil (with igniter), and then try another ECM.

If the spark does not occur, do the test as follows:
(7) Using a 16 mm (0.63 in.) plug wrench, install the
spark plugs.
Torque: 18 N´m (184 kgf´cm, 13 ft´lbf)
(8) Install the ignition coils (with igniter) (See page
IG±7).
2. INSPECT SPARK PLUGS
(a) Remove the ignition coils (with igniter) (See page
IG±6).
(b) Using a 16 mm (0.63 in.) plug wrench, remove the spark
plugs.

(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 madeSK16R11
NGK madeIFR5A11
(e) Check the electrode gap.
Electrode gap: 1.0 ± 1.1 mm (0.039 ± 0.043 in.)
Maximum electrode gap: 1.2 mm (0.047 in.)
If the electrode gap is greater than maximum, replace the spark
plug.
(f) Using a 16 mm (0.63 in.) plug wrench, install the spark
plugs.
Torque: 18 N´m (184 kgf´cm, 13 ft´lbf)
(g) Install the ignition coils (with igniter) (See page IG±7).
3. INSPECT CAMSHAFT POSITION SENSOR
(a) Disconnect the camshaft position sensor connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Resistance:
Cold1,630 ± 2,740 W
Hot2,065 ± 3,225 W
If the resistance is not as specified, replace the camshaft posi-
tion sensor.
(c) Connect the camshaft position sensor connector.
