If operation is not as specified, replace the VSV.
3. INSPECT VENTILATION VALVE SUB±ASSY
(a) Blow air into the cylinder head side, and check that air
passes through easily.
CAUTION:
Do not suck air through the valve. If contains petroleum
substances and is harmful.

ON±VEHICLE INSPECTION
1. INSPECT AIR±FUEL RATIO COMPENSATION SYS-
TEM
HINT:
You can also check the system by choosing ºDATA MONITOR/
O
2 SENSOR OUTPUT VOLTAGEº on the monitor of the hand±
held tester.
(a) Connect the hand±held tester to the terminals 21 (OX1B) and 7 (E1) and to terminals 23 (OX1A) and 7 (E1) of the
ECM.
CAUTION:
Connect test leads from the back side of the connector with
the ECM connected.
(b) Warm up the heated oxygen sensor with the engine speed at 2,500 rpm for approximately 2 minutes.
(c) Confirm that the voltage varies output between 0V to 1V with the engine speed at 2,500 rpm.
OK:
The voltage output varies more than 8 times in 10 se-
conds.
CAUTION:

Perform the check immediately after the warming up.

If the voltage variation could not be verified, warm up
the heated oxygen sensor again.
2. INSPECT FUEL CUT OFF RPM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for injector operating sounds.
(c) Check that injector operating sounds stops momentarily and then resumes when \
the throttle lever is released.
3. INSPECT EVAPORATIVE EMISSION CONTROL SYS-TEM
(a) After starting the engine, disconnect the vacuum hose
shown in the illustration.
(b) Check if vacuum occurs at the VSV port when choosing ºACTIVE TESTº and ºPURGE VSVº according to the dis-
play on hand±held tester.
(c) Finish ºACTIVE TESTº, then reconnect the vacuum.
(d) After entering to ºECU DATA MONITORº on the hand±
held tester, choose ºPURGE VSVº to check the operation
of the purge VSV.
(e) After driving the vehicle with a warm engine, confirm that
the VSV turns from off to on.

ON±VEHICLE INSPECTION
1. INSPECT INTAKE AIR SYSTEM
(a) Check for leakage or clogging between the air cleaner
housing and turbocharger inlet and between the turbo-
charger outlet and cylinder head.
(1) Clogged air cleaner...Clean or replace element
(2) Hoses collapsed or deformed...Repair or replace
(3) Leakage from connections...Check each connec-tion and repair
(4) Cracks in components...Check and replace
2. INSPECT EXHAUST SYSTEM
(a) Check for leakage or clogging between the cylinder head
and turbocharger inlet and between the turbocharger out-
let and exhaust pipe.
(1) Deformed components...Repair or replace
(2) Foreign material in passages...Remove
(3) Leakage from components...Repair or replace
(4) Cracks in components...Check and replace
3. CHECK TURBOCHARGING PRESSURE
(a) Warm up the engine.
(b) Using a 3±way connector, connect SST (turbocharger pressure gauge) to the hose leading to the intake air con-
nector.
SST 09992 ± 00242
(c) While depressing the clutch pedal, press the accelerator pedal down to the full. Measure the turbocharging pres-
sure at maximum speed (5,100 to 5,250 rpm).
Standard pressure:
15 to 45 kPa (0.15 to 0.46 kgf/cm
2, 2.2 to 6.5 psi)
If the pressure is less than specification, check both the intake
air and exhaust systems for leakage.
If there is no leakage, check if the actuator hose has discon-
nected. If not, check the turbocharger.
If the pressure is greater than specification, check if the actua-
tor hose has disconnected or cracked. If not, check the turbo-
charger.
4. INSPECT TURBO PRESSURE SENSOR
(a) Inspect power source voltage (1) Disconnect the turbo pressure sensor connector.
(2) Turn the ignition switch ON.
(3) Using a voltmeter, measure the voltage between
connector terminals 3 (VC) and 1 (E2) of the wiring
harness side.
Voltage: 4.5 to 5.5 V
(4) Turn the ignition switch OFF.
(5) Reconnect the turbo pressure sensor connector.
