ENGINE ELECTRICAL -Ignition System16-26
IGNITION SYSTEM
GENERAL INFORMATION
This system is equipped with two ignition coils (A
and B) with built-in power transistors for the No.
1 and No. 4 cylinders and the No. 2 and No. 3
cylinders respectively.
Interruption of the primary current flowing in the
primary side of ignition coil A generates a high
voltage in the secondary side of ignition coil A.
The high voltage thus generated is applied to the
spark plugs of No. 1 and No. 4 cylinders to generate
sparks. At the time that the sparks are generated
at both spark plugs, if one cylinder is at the
compression stroke, the other cylinder is at the
exhaust stroke, so that ignition of the compressed
air/fuel mixture occurs only for the cylinder which
is at the compression stroke.
In the same way, when the primary current flowing
in ignition coil B is interrupted, the high voltage
thus generated is applied to the spark plugs of
No. 2 and No. 3 cylinders.
The Engine-ECU turns the two power transistors
inside the ignition coils alternately on and off. Thiscauses the primary currents in the ignition coils
to be alternately interrupted and allowed to flow
to fire the cylinders in the order 1-3-4-2.
The Engine-ECU determines which ignition coil
should be controlled by means of the signals from
the camshaft position sensor which is incorporated
in the camshaft and from the crank angle sensor
which is incorporated in the crankshaft. It also
detects the crankshaft position in order to provide
ignition at the most appropriate timing in response
to the engine operation conditions. It also detects
the crankshaft position in order to provide ignition
at the most appropriate timing in response to the
engine operation conditions.
When the engine is cold or operated at high
altitudes, the ignition timing is slightly advanced
to provide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce
output torque, thereby alleviating shifting shocks.

SPARK PLUG CHECK, CLEANING AND REPLACEMENT
SPARK PLUG GAP CHECK
Caution
1. Do not adjust the gap of the iridium plug.
2. Cleaning of the iridium plug could damage the tip of the electrode. Thus, if the plug must
be cleaned because of soot, etc., use a plug cleaner and clean within a short time of 20 seconds
or less to protect the electrode. Do not use a wire brush, etc.
3. Even when the functions of the iridium plug are normal, the electrode section may be blackened.
However, the adhered carbon has properties that easily burned off compared to the conventional
type, so there is no problem. Check the quality of the spark plug by checking the insulation
resistance.
Check the plug gap, and replace if the checked value is more than the limit value.
Standard value, limit value:
MakerModelStandard value (mm)Limit value (mm)
NGKIGR7A-G0.6 - 0.70.75
DENSOVW22PR-DA70.6 - 0.70.75
SPARK PLUG INSULATION RESISTANCE CHECK
Measure the insulation resistance of the spark plug, and
replace if the measured value is less than the limit value.
Limit value: 1 MΩ
CAMSHAFT POSITION SENSOR CHECK
Refer to GROUP 13A - Troubleshooting.
CRANK ANGLE SENSOR CHECK
Refer to GROUP 13A - Troubleshooting.
DETONATION SENSOR CHECK
Check the detonation sensor circuit if self-diagnosis code,
No. 31 is shown.
NOTE
For information concerning the self-diagnosis codes, refer
to GROUP 13A - Troubleshooting.
