TURBOCHARGER ASSEMBLY INSTALLATION
1. Check the internal surface, the eye bolt and the
mating surface of the oil pipe and water pipe for
clogging, and clean if necessary.
2. If deposits of carbon are accumulated on the
turbocharger oil passage, remove them and clean
using the compressed air.
Caution
Be careful not to allow foreign material to enter the
turbocharger.
3. Add clean engine oil through the oil feed pipe port
on the turbocharger.
INSPECTION
Check the following points; replace the part if a problem is
found.
EXHAUST MANIFOLD CHECK
1. Check for damage or cracking of any part.
2. Using a straight edge and a thickness gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
Limit: 0.20 mm
TURBOCHARGER ASSEMBLY CHECK
DVisually check the turbine wheel and the compressor
wheel for cracking or other damage.
DCheck whether the turbine wheel and the compressor
wheel can be easily turned by hand.
DCheck for oil leakage from the turbocharger assembly.
DCheck whether or not the waste gate valve remains open.
If any problem is found, replace the part after disassembly.
OIL PIPE AND OIL RETURN PIPE CHECK
Check the oil pipe and oil return pipe for clogging, bending,
or other damage. If there is clogging, clean it.
EXHAUST MANIFOLD CHECK
Damage or cracking of any part.

INTAKE AND EXHAUST -General Information/Service Specifications/Sealant15-3
At starting and driving at low speed, the duty control
value of the variable geometry solenoid valve is
increased to apply the vacuum pressure of the
vacuum pump to the variable geometry actuator.
Applying the vacuum pressure to the variable
geometry actuator pulls the actuator rod so that
it can move towards the direction of closing the
variable nozzle of the variable geometry
turbocharger. As closing the nozzle reduces the
exhaust gas mass, the speed of exhaust gas flow
will be increased and efficiency will be improved.
Since the characteristic of boost pressure becomes
a low speed type, boost pressure will suddenly
rise from low speed.
At driving at high speed, the duty control value
of the variable geometry solenoid valve is
decreased to reduce the vacuum pressure from
the vacuum pump so that the actuator rod can
return to the deactivated status and move towards
the direction of opening the nozzle of the variable
geometry turbocharger.Opening the nozzle allows the characteristic of
boost pressure to become a high speed type so
that the appropriate boost pressure can be
maintained.
Therefore, boost pressure can be controlled by
appropriate duty control of the variable geometry
solenoid valve. The engine-ECU calculates the
correct boost pressure based on the engine speed
and fuel injection amount. Furthermore, the duty
control of the variable geometry solenoid valve is
given feedback of the signals from the variable
geometry control pressure sensor and the boost
pressure sensor so that the variable nozzle opening
angle of the variable geometry turbocharger can
be quickly adjusted to obtain the desired boost
pressure.

SECONDARY COIL CHECK
NOTE
It is impossible to check the secondary coil through the
continuity check as a diode is integrated in the secondary
coil circuit of this ignition coil. So, check the secondary coil
in the following procedure.
1. Disconnect the ignition coil connector.
2. Remove the ignition coil and install a new spark plug
to the ignition coil.
3. Connect the ignition coil connector.
4. Earth the side electrode of the spark plug and crank
the engine.
5. Check that spark is produced between the electrodes of
the spark plug.
6. If no spark is produced, replace the ignition coil with a
new one and recheck.
7. If spark is produced with the new ignition coil, replace
the old one as it is faulty. If no spark is produced again,
the ignition circuit is suspected as faulty. Check the ignition
circuit.
SPARK PLUG CHECK AND CLEANING
Caution
1. The spark plug gap for iridium plugs should not be
adjusted.
2. Cleaning iridium plugs may result in damage to the
iridium tip. Therefore, if cleaning is necessary
because the plug is sooty, use a plug cleaner, and
do not clean the plug for more than 20 seconds in
order to preserve the electrodes. A wire brush should
never be used.
3. The spark plugs in GDI engines are special iridium
plugs in which the electrodes can become black even
when the plugs are working normally. Carbon which
may become deposited on these plugs burns off more
readily than with conventional plugs, and so should
not cause any problems with spark plug performance.
Judgement of whether a spark plug is operating
normally or not should be made by checking the
insulation resistance.
