a. Place differential case in the upright position so that the side
gear to be measured is at the top.
(A): Location for inserting feeler gauge
(B): Side gear tooth
(C): The center line of differential case
b. In order to maximize the back clearance, rotate side gears so
that a tooth on side gears at the top and bottom will align at the
same position as shown in the figure.
c. Adjust the back clearance of side gear according to the following
procedures.
i. Insert feeler gauges A of the same thickness to the back of side
gear from both sides, preventing side gear from falling, to mea-
sure the clearance.
• Measure clearance 3 times by rotating side gears and take the
average.
CAUTION:
In all 3 measurements, maximize the clearance by aligning
teeth on side gears at the top and bottom at the same posi-
tion.
ii. Select side gear thrust washer so that the clearance will fall
within the standard.
iii. Turn differential case upside down, and measure the back clear-
ance of the other side gear in the same manner.
NOTE:
Adjust the clearance to approx. 0.1 mm (0.004 in) for used differ-
ential [driven approx. 3,000 km (1864 mile) or more].
4. Install lock pin (1) to pinion mate shaft using the pin punch A.
CAUTION:
• Do not reuse lock pin.
• Make sure that lock pin is flush with differential case.
5. Install speedometer drive gear on differential case.

DTC P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)
DTC P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SEN-
SOR)
DescriptionINFOID:0000000001703512
The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of the
CVT output shaft and emits a pulse signal. The pulse signal is sent to the TCM, which converts it into vehicle
speed.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001703513
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001703514
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0720 VEH SPD SEN/CIR AT” with CONSULT-III is detected TCM does not
receive the proper signal from the sensor.
Possible CauseINFOID:0000000001703515
• Harness or connectors
(Sensor circuit is open or shorted.)
• Output speed sensor (Secondary speed sensor)
DTC Confirmation ProcedureINFOID:0000000001703516
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and maintain the following conditions for at least 12 consecutive seconds.
ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
3. If DTC is detected, go to CVT-82, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.

NG >> GO TO 2.
2. CHECK SECONDARY SPEED SENSOR
With CONSULT-III
1. Start engine.
2. Check power supply to output speed sensor (secondary speed sensor) by voltage between TCM connec-
tor terminals 10, 19 and 42. Refer to CVT-36, "
Circuit Diagram" .
3. If OK, check the pulse when vehicle cruises.
OK or NG
OK >> GO TO 8.
NG >> GO TO 3.
3. CHECK POWER AND SENSOR GROUND
1. Turn ignition switch OFF.
