ON±VEHICLE INSPECTION
SPARK TEST
CHECK THAT SPARK OCCURS
(a) Remove the ignition coil. (See ignition coil removal)
(b) Remove the spark plug.
(c) Install the spark plug to the ignition coil, and connect the
ignition coil connecter.
(d) Ground the spark plug.
(e) Check if spark occurs while engine is being cranked.
HINT: To prevent gasoline from being injected from injectors
during this test, crank the engine for no more than 1±2 se-
conds at time.
If the spark does not occur, do the test as follows:
SPARK TEST
CHECK CONNECTION OF IGNITION COIL, IGNITER
CHECK POWER SUPPLY TO IGNITION COIL AND
IGNITER
1. Turn ignition switch to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal.
CHECK RESISTANCE OF IGNITION COIL(See page IG±23)Resistance: Cold Hot
Primary 0.54 ± 0.84
0.68 ± 0.98

CHECK RESISTANCE OF CAMSHAFT AND
CRANKSHAFT POSITION SENSOR
(See page IG±24)Resistance: Cold Hot
NIPPONDENSO 835 ± 1,400
1,060 ± 1,645

AISAN 985 ± 1,600
1,265 ± 1,890

CHECK IGT SIGNAL FROM ECM(See page EG±519)
TRY ANOTHER IGNITER
Connect securely.
Check wiring between ignition switch
to ignition coil and igniter.
Replace the ignition coil.
Replace the camshaft and crankshaft position
sensor.
Check wiring between ECM,and igniter, and
then try another ECM.
