INSPECTION
1. REMOVE VSV ASSEMBLY
2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: 38.5 - 44.5 W at 20°C (68°F)
If there is no continuity, replace the VSV.
3. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
4. INSPECT VSV OPERATION
(a) Check that air flows from port E to the filter.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to F.
If operation is not as specified, replace the VSV.
5. REINSTALL VSV ASSEMBLY

ON-VEHICLE INSPECTION
1. INSPECT INTAKE AIR SYSTEM
Check for leakage or clogging between the air cleaner and
turbocharger inlet and between the turbocharger outlet and cyl-
inder head.
Clogged air cleaner ..Clean or replace air filter
Hoses collapsed or deformed .... Repair or replace
Leakage from connections .... Check each
connection and repair
Cracks in components .... Check and replace
2. INSPECT EXHAUST SYSTEM
Check for leakage or clogging between the cylinder head and
turbocharger inlet and between the turbocharger outlet and ex-
haust pipe.
Deformed components .... Repair or replace
Foreign material in passages .... Remove
Leakage from components .... Repair or replace
Cracks in components .... Check and replace
3. INSPECT EXHAUST GAS CONTROL
VALVE OPERATION
(a) Disconnect the air hose from the actuator.
(b) Using SST, apply approx. 49 kPa (0.50 kgf/cm
2, 7.1 psi)
of pressure to the actuator.
SST 09992-00242
(c) Check that the actuator push rod moves.
(d) Reconnect the air hose to the actuator.
If operation is not as specified, replace the control valve assem-
bly.
4. INSPECT TURBOCHARGING PRESSURE
(a) Using a 3-way connector, connect SST (turbocharger
pressure gauge) to the hose between the gas filter and
turbo pressure sensor.
SST 09992-00242
(b) While driving with the engine running at 5,600 rpm or
more with the throttle valve fully open in the 1st gear/L
range, check the turbocharging pressure.
Standard pressure:
61 - 75 kPa (0.62 - 0.76 kgf/cm
2, 8.8 - 10.8 psi)
If the pressure is less than that specified, check the intake and
exhaust systems for leakage. If there is no leakage, replace the
turbocharger assembly.
If the pressure is above specification, check if the actuator hose
is disconnected or cracked. If not, replace the turbocharger as-
sembly.
