DescriptionINFOID:0000000005928787
• The CVT fluid temperature sensor is included in the control valve assembly.
• The CVT fluid temperature sensor detects the CV T fluid temperature and sends a signal to the TCM.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005928788
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005928789
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0710” with CONSULT-III is detected when TCM receives an excessively low or
high voltage from the sensor.
Possible CauseINFOID:0000000005928790
• Harness or connectors (Sensor circuit is open or shorted.)
• CVT fluid temperature sensor
DTC Confirmation ProcedureINFOID:0000000005928791
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 14 minutes (Total). VEHICLE SPEED: 10 km/h (6 MPH) or more
RANGE: “D” position
4. If DTC is detected, go to CVT-69, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.

3. Read out the value of “ATF TEMP SEN”.
Without CONSULT-III
1. Start engine.
2. Check voltage between TCM connector terminals.
3. Turn ignition switch OFF.
4. Disconnect TCM connector.
5. Check if there is continuity between connector terminal and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK CVT FLUID TEMP ERATURE SENSOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect the TCM connector.
3. Check resistance between TCM connector terminals.
