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.

TURBO CHARGER SYSTEM (1CD–FTV)
INSPECT INTAKE AIR SYSTEM
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
INSPECT EXHAUST SYSTEM
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
CHECK TURBOCHARGING PRESSURE
Warm up the engine.
Using a 3–way connector, connect SST (turbocharger
pressure gauge) to the hose leading to the intake air con-
nector.

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
INSPECT TURBO PRESSURE SENSOR
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.
