OPERATIONl
Turn ignition switch to .“ON”position, and batteryvoltage will be applied to primary winding of
ignition coil.l
When crankshaft position sensor and camshaft
position sensor signal is input to engine control
module, engine control module makes ON-OFF
control of power transistors one by one.l When power transistor is turned on, current
flows from ignition coil (primary winding) to
ground through power transistor.l When power transistor A is turned from ON
to OFF, the spark plugs of No. 1 and No. 4
cylinders spark. Turning of power transistor B
from ON to OFF will produce sparking in spark
plugs of No. 2 and No. 5 cylinders. Furthermore,
when power transistor C is turned from ON toOFF, sparking is produced in spark plugs of
No. 3 and No. 6 cylinders.
TROUBLESHOOTING HINTS1. Engine cranks, but does not start.
(1) Spark is insufficient or does not occur at
all (on spark plug).l Check ignition coil.
l Check camshaft position sensor and
crankshaft position sensorl Check power transistor.
l Check spark plugs.
l Check spark plug cable.
(2) Spark is good.
l Check ignition timing.
2. Engine idles roughly or stalls.
l Check spark plugs.
l Check ignition timing.
l Check ignition coil.
l Check spark plug cable.
3. Poor acceleration
l Check ignition timing.
l Check spark plug cable.
l Check ignition coil.

SPARK PLUGCheck the plug gap and replace if the limit is exceeded.
Standard value:
1.0-l .l mm (.039-.043 in.)
Limit: 1.3 mm
(.051 in.)
Caution
1.Do not attempt to adjust the gap of the platinum plug.
2.Cleaning of the platinum plug may damage the plati-num tip. Therefore, if carbon deposits must be re-
moved, use a plug cleaner and complete cleaning with-
in 20 seconds for protection of the electrode. Do not
use wire brushes.
SPARK PLUG CABLE(1) Check cap and coating for cracks.
(2) Measure resistance.Limit: Max. 22

NOTE
An analog-type circuit tester should be used.No. l-No. 4 coil side
(1)Connect the negative (-) terminal of the 1.5 V power supply
to terminal (4) of the ignition power transistor; then check
whether there is continuity between terminal (13) and termi-nal (4) when terminal (3) and the positive
(+) terminal
are connected and disconnected.NOTE
Connect the (-) probe of the circuit tester to terminal (13).
