MANUAL SHIFTING TEST
1. PERFORM MANUAL SHIFTING TEST
HINT:
S With this test, it can be determined whether the trouble oc-
curs in the electrical circuit or is a mechanical problem in
the transaxle.
S If any abnormalities are found in the following test, the
problem is in the transaxle itself.
(a) Disconnect the transmission wire connector.
(b) Drive with the transmission wire disconnected. Shifting the shift lever to the D position to check whether
the shifting condition changes the table below.
Shift PositionShifting Condition
DNo Shift (Not Change)
HINT:
When driving with the transmission wire disconnected, the gear
position will be as follows:
S When the shift lever is in the D position, the gear is held
in the 4th position.
S When the shift lever is in the R or the P position, the gear
is also in the R or the P position respectively.
(c) Connect the transmission wire connector.
(d) Clear the DTC (see page 05 −557).

HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:
SPerform the test at the normal operation fluid temper-
ature the 50 to 80˚C(122 to176˚F)
SThe line pressure test should always be carried out in
pairs. One technician should observe the conditions
of wheels or wheel stoppers outside the vehicle while
the other is performing the test.
SBe careful to prevent SST hose from interfering with
the exhaust pipe.
SThis check must be conducted after checking and ad-
justing engine.
SPerform under condition that A/C is OFF.
SWhen conducting stall test, do not continue more
than10 seconds.
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Lift the vehicle up.
(3) Remove the engine under cover.
(4) Connect hand−held tester to DLC3.
(5) Remove the test plug A on the transaxle case front
left side and install the SST.
SST 09992−00095 (09992−00231, 09992−00271)
NOTICE:

tion and R position.
(6) Start the engine.
(7) Using hand−held tester, shift to D position and hold
3rd gear by active test, and measure the line pres-
sure in idling.
Specified line pressure:
ConditionD position
Idling372 to 412 kPa

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) Turn the ignition switch to OFF.
(5) Reconnect the turbo pressure sensor connector.
(b) Inspect the supply power.
(1) Turn the ignition switch to ON.
(2) Disconnect the vacuum hose from the turbo pres-
sure sensor.
(3) Connect a voltmeter to terminals E12−28 (PIM) and
E13−28 (E2) of the ECM, then measure the output
voltage under atmospheric pressure.
(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).
Voltage drop:
Apply Vacuum
[kPa (mmHg, in.Hg)]Voltage Decrease
[V]
13.3 (100, 3.94)0.1 to 0.3
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)]
Voltage Increase
[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
If the result is not as specified, check the wiring and ECM.

PRECAUTION
1. MAINTENANCE PRECAUTION
(a) Do not stop the engine immediately after pulling a trailer,
or after high speed or uphill driving. Let the engine idle for
20 to 120 seconds before turning the ignition switch to
OFF (according as the driving condition, the idling time
varies).
(b) Avoid quickly accelerating the pedal or increasing the en-
gine speed immediately after starting a cold engine.
(c) If the turbocharger is found defective, it must be replaced.
Also, inspect the source of the trouble including condi-
tions of the turbocharger that having been used. Repair
or replace the followings if necessary:
(1) Engine oil (level and quality)
(2) Oil lines leading to the turbocharger
(d) Pay due attention when removing and reinstalling the
turbocharger assembly. Do not drop, grasp, or give shock
to the easily−deformed assembly parts such as the actua-
tor or push rod when removing or reinstalling.
(e) Before removing, cover both the intake and exhaust ports
and the oil inlet to prevent dirt or foreign objects from be-
ing introduced.
(f) If replacing the turbocharger, check the oil pipe for depos-
its. If necessary, replace the oil pipe, too.
(g) Thoroughly remove old gasket sticking to the lubrication
oil pipe flange and turbocharger oil flange.
(h) If replacing the bolt(s) or nut(s), Toyota genuine parts
must be used to prevent breakage or deformation.
(i) If replacing the turbocharger, put 20 cm
3(1.2 cu in.) of
fresh oil into the turbocharger oil inlet hole, then turn the
turbine wheel by hand to spread oil to the bearing.
(j) If overhauling or replacing the engine, cut the fuel supply
after reassembling and crank the engine for 30 seconds
to feed oil throughout the engine. Run the engine at idle
for 60 seconds.

(k) Since the turbine wheels run at extremely high speed, if
the engine is running without the air cleaner, case cover
and hose, the turbine wheel will be damaged by
introduced foreign particles.
