DTC P0710 CVT FLUID TEMPER
ATURE SENSOR CIRCUIT
Description INFOID:0000000004305634
• 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 Val ue in Data Monitor Mode INFOID:0000000004305635
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004305636
• 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 Cause INFOID:0000000004305637
• Harness or connectors (Sensor circuit is open or shorted.)
• CVT fluid temperature sensor
DTC Confirmation Procedure INFOID:0000000004305638
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESU LTS” 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-251, " 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

Diagnosis Procedure
INFOID:00000000043056401.
CHECK CVT FLUID TEMP ERATURE SENSOR SIGNAL
With CONSULT-III
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONITO R” mode for “TRANSMISSION” 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.
OK or NG OK >> GO TO 5.
NG >> GO TO 3. 3.
CHECK CVT FLUID TEMPERATURE SENSOR
1. Turn ignition switch OFF.
2. Disconnect CVT unit harness connector. Item name Condition
