INFOID:0000000001703495
1. CHECK PNP SW SIGNALS
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Change selector lever to “P”, “R”, “N”, “D” and “L” positions to check the value of “INH SW1”“INH SW2”
“INH SW3”“INH SW4” and “INH SW3M”.
Without CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Change selector lever to “P“, “R”, “N”, “D” and “L” positions to
check voltage between the TCM connector terminals and

DTC P0710 CVT FLUID TEMPERATURE SENSOR CIRCUIT
DescriptionINFOID:0000000001703497
• The CVT fluid temperature sensor is included in the control valve assembly.
• The CVT fluid temperature sensor detects the CVT fluid temperature and sends a signal to the TCM.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001703498
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001703499
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0710 ATF TEMP SEN/CIRC” with CONSULT-III is detected when TCM receives
an excessively low or high voltage from the sensor.
Possible CauseINFOID:0000000001703500
• Harness or connectors
(Sensor circuit is open or shorted.)
• CVT fluid temperature sensor
DTC Confirmation ProcedureINFOID:0000000001703501
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. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Start engine and maintain the following conditions for at least 10 minutes (Total).
VEHICLE SPEED: 10 km/h (6 MPH) or more
ENG SPEED: 450 rpm more than
ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
4. If DTC is detected, go to CVT-73, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
Item name Condition Display value (Approx.)
ATF TEMP SEN When CVT fluid temperature is 20°C (68°F). 2.0 V
When CVT fluid temperature is 80°C (176°F). 1.0 V
