P1710
P1710 A/T FLUID TEMPERATURE SENSORDescription
The A/T fluid temperature sensor detects the A/T fluid temperature and transmits a signal to the TCM.
DTC Logic
P1710:
DTC CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
NOTE: If "DTC CONFIRMATION PROCEDURE" has been previously performed, always turn ignition switch OFF. Then wait at least 10 seconds before performing the next test.
1. CHECK DTC DETECTION
With CONSULT-III
1. Start the engine.
2. Select "Data Monitor" mode for "TRANSMISSION".
3. Drive vehicle and maintain the following conditions for at least 10 minutes (total). (It is not necessary to maintain continuously)
VHCL/S SE-A/T: 10 km/h (6 MPH) or more
ACCELE POSI: More than 1.0/8
SLCT LVR POSI: "D" position
With GST
Follow the procedure "With CONSULT-III".
Is "P1710 ATF TEMP SEN/CIRC" detected?
YES >> Go to "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-38, "Intermittent Incident". Service Information For Electrical Incident
Diagnosis Procedure
1. CHECK A/T FLUID TEMPERATURE SENSOR 1 SIGNAL
With CONSULT-III
1. Start the engine.
2. Select "Data Monitor" mode for "TRANSMISSION".
3. Check "ATF TEMP SE 1" and "ATF TEMP SE 2" values.
Which item is abnormal?
ATF TEMP SE 1 >> GO TO 2.
ATF TEMP SE 2 >> GO TO 5.
2. CHECK A/T FLUID TEMPERATURE SENSOR 1
1. Remove control valve with TCM.
2. Disconnect park/neutral position switch connector.
3. Check A/T fluid temperature sensor 1. Refer to "Component Inspection (A/T fluid temperature sensor 1)".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts.
3. CHECK SUB-HARNESS
1. Disconnect TCM connector.
2. Check continuity between park/neutral position switch connector terminals and TCM connector terminals.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace damaged parts.
4. DETECT MALFUNCTIONING ITEM
Check the following.
^ Check terminals of park/neutral position switch connector and TCM connector, and harness cladding for damage.
^ Check connector for loose connection.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Repair or replace damaged parts.
5. CHECK A/T FLUID TEMPERATURE SENSOR 2
1. Remove A/T fluid temperature sensor 2.
2. Check A/T fluid temperature sensor 2. Refer to "Component Inspection (A/T fluid temperature sensor 2)".
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace damaged parts.
6. CHECK TERMINAL CORD ASSEMBLY
1. Remove control valve with TCM.
2. Disconnect TCM connector.
3. Check continuity between A/T fluid temperature sensor 2 connector terminals and TCM connector terminals.
Is the inspection result normal?
YES >> GO TO 7.
NO >> Repair or replace damaged parts.
7. DETECT MALFUNCTIONING ITEM
Check the following.
^ Check terminals of A/T fluid temperature sensor 2 connector and TCM connector, and harness cladding for damage.
^ Check connector for loose connection.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Repair or replace damaged parts.
8. CHECK TCM POWER SUPPLY AND GROUND CIRCUIT
Check TCM power supply and ground circuit. Refer to TM-89, "Diagnosis Procedure". Main Power Supply and Ground Circuit
Is the inspection result normal?
YES >> Replace the control valve with TCM.
NO >> Repair or replace damaged parts.
Component Inspection (A/T fluid temperature sensor 1)
1. CHECK A/T FLUID TEMPERATURE SENSOR 1
Check resistance between park/neutral position switch connector terminals.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace control valve with TCM.
Component Inspection (A/T fluid temperature sensor 2)
1. CHECK A/T FLUID TEMPERATURE SENSOR 2
Check resistance between A/T fluid temperature sensor 2 connector terminals.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace the A/T fluid temperature sensor 2.
