Diagnostic ProcedureUCS005ZP
1. CHECK INPUT SIGNALS
With CONSULT-II
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Start vehicle and read out the value of “PRI SPEED SEN”.
OK or NG
OK >> GO TO 6.
NG >> GO TO 2.
2. CHECK INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)
1. Start engine.
2. Check voltage between TCM connector terminals.
3. Check the pulse with CONSULT-II or oscilloscope, when vehicle
cruises.
OK or NG
OK >> GO TO 6.
NG - 1 >> Battery voltage is not supplied: GO TO 3.
NG - 2 >> Battery voltage is supplied, but there is a malfunction in
the frequency: GO TO 4.

OK or NG
OK >> GO TO 6.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
4. CHECK HARNESS BETWEEN TCM AND CVT UNIT HARNESS CONNECTOR [INPUT SPEED SEN-
SOR (PRIMARY SPEED SENSOR)]
1. Turn ignition switch OFF.
2. Disconnect TCM connector and CVT unit harness connector.
3. Check continuity between TCM connector terminal and CVT unit
harness connector terminal.
4. If OK, check harness for short to ground and short to power.

OK or NG
OK >> GO TO 5.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
5. CHECK THE TCM SHORT
Replace same type TCM, perform self-diagnosis check. Erase self-diagnostic results and then drive the vehi-
cle [10 km/h (6 MPH) or more], perform self-diagnosis check. Refer to CVT-90, "
DTC Confirmation Procedure"
.
Is the
“P0715 INPUT SPD SEN/CIRC” detected again?
YES >> Replace the transaxle assembly. Refer to CVT-207, "Removal and Installation" .
NO >> Replace TCM. Refer to CVT-9, "
Service After Replacing TCM and Transaxle Assembly" .
6. CHECK DTC
Perform CVT-90, "
DTC Confirmation Procedure" .
OK or NG
OK >>INSPECTION END
NG >> GO TO 7.

DTC P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)
PFP:31935
DescriptionUCS005ZQ
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-II Reference ValueUCS005ZR
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005ZS

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0720 VEH SPD SEN/CIR AT” with CONSULT-II is detected TCM does not
receive the proper signal from the sensor.
Possible CauseUCS005ZT

Harness or connectors
(Sensor circuit is open or shorted.)

Output speed sensor (Secondary speed sensor)
DTC Confirmation ProcedureUCS005ZU
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-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
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-97, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
Item name Condition Display value
VSP SENSOR During driving Approximately matches the speedometer reading.
