IGNITION SYSTEM
ENGINE ELECTRICAL16-30
IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
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. This causes 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.

M1173007400208
POSITIVE CRANKCASE VENTILATION
SYSTEM CHECK
M1173001100179
1. Remove the ventilation hose from the PCV valve.
2. Remove the PCV valve from the rocker cover.
3. Reinstall the PCV valve at the ventilation hose.
4. Start the engine and run at idle.
5. Place a finger at the opening of the PCV valve
and check that vacuum of the intake manifold is
felt.
NOTE: At this moment, the plunger in the PCV
valve moves back and forth.
6. If vacuum is not felt, clean the PCV valve or
replace it.
POSITIVE CRANKCASE VENTILATION
(PCV) VALVE CHECK
M1173001200187
1. Insert a thin rod into the PCV valve from the side
shown in the illustration (rocker cover installation
side), and move the rod back and forth to check
that the plunger moves.
2. If the plunger does not move, there is a clogging
in the PCV valve. In this case, clean or replace
the PCV valve.
EVAPORATIVE EMISSION CONTROL
SYSTEM
GENERAL INFORMATION (EVAPORATIVE
EMISSION CONTROL SYSTEM)
M1173005100405
The evaporative emission control system prevents
fuel vapours generated in the fuel tank from escaping
into the atmosphere.
Fuel vapours from the fuel tank flow through the fuel
tank pressure control valve and vapour pipe/hose to
be stored temporarily in the canister.
When driving the vehicle, fuel vapours stored in the
canister flow through the purge solenoid and purge
port and go into the intake manifold to be sent to the
combustion chamber.
When the engine coolant temperature is low or when
the intake air quantity is small (when the engine is at
idle, for example), the engine control unit turns the
purge solenoid off to shut off the fuel vapour flow to
the intake manifold.
This does not only insure the driveability when the
engine is cold or running under low load but also
stabilize the emission level.

1. Disconnect the vacuum hose (red stripe) from
throttle body and connect it to a hand vacuum
pump.
2. Plug the nipple from which the vacuum hose was
removed.
3. When the engine is cold or hot, apply a vacuum of
53 kPa, and check the condition of the vacuum.
When engine is cold
(Engine coolant temperature: 40°C or less)
When engine is hot
(Engine coolant temperature: 80°C or higher)

1. Disconnect the vacuum hose (red stripe) from the
throttle body and connect a hand vacuum pump to
the nipple.
2. Plug the vacuum hose (red stripe).3. Start the engine.
4. Check that a fairly constant negative pressure is
generated regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.
