INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the hand−held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
(a) Turn the ignition switch off.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Push the ”ON” button of the hand−held tester.
(e) Select the item ”DIAGNOSIS / OBD/MOBD / DATA LIST”.
(f) According to the display on tester, read the ”DATA LIST”.

2. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand −held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method
to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the hand −held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Push the ”ON” button of the hand −held tester.
(f) Select the item ”DIAGNOSIS / OBD/MOBD / ACTIVE TEST”.
(g) According to the display on tester, perform the ”ACTIVE TEST”.

self.
[Vehicle Condition]
Less than 50 km/h (3 1 mph)
[Others]
S Press ” ” button: Shift up
S Press ” ” button: Shift down
Possible to check the operation of
the shift solenoid valves.
LOCK UP
[Test Details]
Control the shift solenoid DSL to set the automatic transaxle to the
lock−up condition.
[Vehicle Condition]
Vehicle Speed: 60 km/h (37 mph) or more, and 5th gear
Possible to check the DSL opera-
tion.
LINE PRESS UP *
[Test Details]
Operate the shift solenoid SLT and raise the line pressure.
[Vehicle Condition]
S Vehicle Stopped.
S IDL: ON
[HINT]
OFF: Line pressure up (When the active test of ”LINE PRESS UP” is
performed, the ECM commands the SLT solenoid to turn off).
ON: No action (normal operation)
−
*: ”LINE PRESS UP” in the ACTIVE TEST is performed to check the line pressure changes by connecting
the SST to the automatic transaxle, which is used in the HYDRAULIC TEST (see page 05 −538) as well.
HINT:
The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.

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.

When Electronic Throttle Control System (ETCS) is mal-
functioning, electric current to throttle actuator is cut off and
throttle valve returns to throttle position (TP) 16 by its
spring.
Then, required engine power is calculated using ignition
timing and Accelerator Pedal Position (APP). Engine is
controlled by intermittent fuel–cut.
As a result, fully slowly depressing accelerator pedal en-
ables driving at minimum speed. However, quickly depress-
ing pedal would vary vehicle speed remarkably.

Accelerator Pedal Position (APP) sensor has main circuit
and associate circuit. When one of circuits is malfunction-
ing, APP is calculated by output of other circuit. When both
of circuits are malfunctioning, it is interpreted that accelera-
tor pedal is releasing. As a result, throttle valve is closed
and engine idles.
