P0710

P0710 TRANSMISSION FLUID TEMPERATURE SENSOR A





Description
- CVT fluid temperature sensor is installed to control valve.
- CVT fluid temperature sensor detects CVT fluid temperature in oil pan.
- The CVT fluid temperature sensor converts CVT fluid temperature into output voltage and transmits the signal to TCM.
- The CVT fluid temperature sensor uses a thermistor and its electrical resistance varies as the temperature varies. The electrical resistance decreases as the temperature increases.

DTC CONFIRMATION PROCEDURE

CAUTION:
Always drive vehicle at a safe speed.
1.PRECONDITIONING (PART 1)
Immediately after performing any "DTC CONFIRMATION PROCEDURE", always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
- GO TO 2.
2.PRECONDITIONING (PART 2)
With CONSULT-III
1. Turn ignition switch ON.
2. Select "Data Monitor" in "TRANSMISSION".
3. Select "ATF TEMP SEN".
Is "ATF TEMP SEN" value within 2.03 - 0.16 V?
YES - INSPECTION END
NO-1 ("ATF TEMP SEN" indicates 0.15 V or less.)-Go to P0710.
NO-2 ("ATF TEMP SEN" indicates 2.04 V or more.)-GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT-III
1. Start the engine.
2. Select "Data Monitor" in "TRANSMISSION".
3. Select "RANGE" and "VEHICLE SPEED".
4. Drive the vehicle.
5. Maintain the following conditions for 14 minutes or more.





6. Stop the vehicle.
7. Select "Self Diagnostic Results" in "TRANSMISSION".
With GST
Follow the procedure "With CONSULT-III".
Is "P0710" detected?
YES - Go to P0710.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT (PART 1)
1. Turn ignition switch ON.
2. Check resistance between TCM vehicle side harness connector terminals.





Is the inspection result normal?
YES - GO TO 2.
NO - GO TO 3.
2.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT (PART 2)
1. Disconnect TCM connector.
2. Check continuity between TCM vehicle side harness connector terminal and ground.





Is the inspection result normal?
YES - Check intermittent incident. Intermittent Incident.
NO - GO TO 3.
3.CHECK CVT FLUID TEMPERATURE SENSOR
1. Turn ignition switch OFF.
2. Disconnect CVT unit connector.
3. Check CVT fluid temperature sensor. P0710.
Is the inspection result normal?
YES - GO TO 4.
NO - CVT fluid temperature sensor is malfunctioning. Replace transaxle assembly. Exploded View.
4.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT FLUID TEMPERATURE SENSOR) (PART 1)
1. Disconnect TCM connector.
2. Check continuity between TCM vehicle side harness connector terminals and CVT unit vehicle side harness connector terminals.





Is the inspection result normal?
YES - GO TO 5.
NO - Repair or replace damaged parts.
5.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT FLUID TEMPERATURE SENSOR) (PART 2)
Check continuity between TCM vehicle side harness connector terminals and ground.





Is the inspection result normal?
YES - Check intermittent incident. Intermittent Incident.
NO - Repair or replace damaged parts.




Component Inspection (CVT Fluid Temperature Sensor)
1.CHECK CVT FLUID TEMPERATURE SENSOR (PART 1)
Check resistance between CVT unit harness connector terminals.





Is the inspection result normal?
YES - GO TO 2.
NO - CVT fluid temperature sensor is malfunctioning. Replace transaxle assembly. Exploded View.
2.CHECK CVT FLUID TEMPERATURE SENSOR (PART 2)
Check continuity between CVT unit vehicle side harness connector terminal and ground.





Is the inspection result normal?
YES - INSPECTION END
NO - CVT fluid temperature sensor is malfunctioning. Replace transaxle assembly. Exploded View.
