(f) Inspect and adjust the shift lever position.
When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator is not aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(1) Loosen the nut on the shift lever.
(2) Push the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to N posi-
tion.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, tighten the shift lever nut.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(6) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
(g) Inspect and adjust the park/neutral position.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.
If it is not as stated above, carry out the following adjustment
procedures.
(1) Loosen the park/neutral position switch bolt and set
the shift lever to the N position.
(2) Align the groove and neutral basic line.
(3) Hold in position and tighten the bolt.
Torque: 5.4 N´m (55 kgf´cm, 48 in´lbf)
For continuity inspection of the park/neutral position
switch, see page DI±479.
(h) Check the idle speed.
Idle speed: 700 ± 50 rpm
(In N position and air conditioner OFF)
6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).
Do not continuously run this test longer than 5 seconds.
To ensure safety, conduct this test in a wide, clear level area which provides good traction.
The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.

7. HYDRAULIC TEST
Measure the line pressure
NOTICE:
Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).
The 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 doing the test.
Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See page AX±21 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressed firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)

DTC31, 32, 33, 34Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.
DTC No.DTC Detecting ConditionTrouble Area

Detection of any of conditions from 1. through 4.:
1. Vehicle speed is at 10 km/h (6 mph) or more and the
speed sensor signal circuit is open or short circuit con-
tinues for 15 sec. or more.
2. Momentary interruption of the speed sensor signal oc-
curs 7 times or more.
3. Vehicle speed is at 20 km/h (12mph) or more and inter-
ference on the speed sensor signal continues for 5 sec.
or more.

continues for 0.5 sec. or more.
