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 turbocharger outlet and cylinder head.
ConditionOperation
Clogged air cleanerClean or replace the element
Collapsed or deformed hosesRepair or replace
Leakage from connectionsCheck each connection and repair
Cracks in componentsCheck and replace
2. INSPECT EXHAUST SYSTEM
(a) Check for leakage or clogging between the cylinder head and turbocharger inlet and between the
turbocharger outlet and exhaust pipe.
ConditionOperation
Deformed componentsRepair or replace
Foreign material in passagesRemove
Leakage from componentsRepair or replace
Cracks in componentsCheck 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 fully. Measure the turbocharging pressure at
the 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 the specification, check if the ac-
tuator hose has disconnected or cracked. If not, check the
turbocharger.
4. INSPECT TURBO PRESSURE SENSOR
(a) Inspect the power source voltage.
(1) Disconnect the turbo pressure sensor connector.
(2) Turn the ignition switch to ON.
(3) Using a voltmeter, measure the voltage between
connector terminals 3 (VC) and 1 (E2) of the wire
harness side.
Voltage: 4.5 to 5.5 V
If the result is not as specified, check the wiring and ECM.

(4) Apply vacuum to the turbo pressure sensor in 13.3
kPa (100 mmHg, 3.94 in.Hg) to 66.7 kPa (500
mmHg, 19.69 in.Hg).
(5) Measure the voltage decrease from step (3).

26.7 (200, 7.87)0.3 to 0.5
40.0 (300, 11.81)0.5 to 0.7
57.3 (400, 15.75)0.7 to 0.9
66.7 (500, 19.69)0.9 to 1.0
(6) Using SST (a turbocharger pressure gauge), apply
pressure to the turbo pressure sensor in 19.6 kPa
(0.20 kgf/cm
2, 2.84 psi) to 98.0 kPa (1.00 kgf/cm2,
14.2 psi).
SST 09992−00242
(7) Measure the voltage increase from step (3).
Voltage up:
Applied Pressure
[kPa (kgf/cm2, psi)]

[V]
19.6 (0.20, 2.84)0.1 to 0.4
39.2 (0.40, 5.69)0.4 to 0.7
58.8 (0.60, 8.53)0.7 to 1.0
78.5 (0.80, 11.4)1.0 to 1.3
98.0 (1.00, 14.2)1.3 to 1.6
