P0711

DTC P0711 FLUID TEMPERATURE SENSOR PERFORMANCE

Description
The A/T fluid temperature sensor detects the A/T fluid temperature and sends a signal to the TCM.

On Board Diagnosis Logic
- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "FLUID TEMP SEN" with CONSULT-II or P0711 without CONSULT-II is detected when ATF temperature signal does not change.

Possible Cause
- Harness or connectors (The sensor circuit is open or shorted.)
- A/T fluid temperature sensor

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" and wait at least 10 seconds before performing the next test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

WITH CONSULT-II





1. Turn ignition switch "ON". (Do not start engine.)
2. Select "A/T" with "DATA MONITOR" mode in CONSULT-II.
3. Start engine.
4. Drive vehicle and maintain the following conditions for at least 15 minutes (Total). (It is not necessary to maintain continuously.)
VHCL SPEED SE-A/T: 40 km/h (25 MPH) or more
SLCT LVR POSI: "D" position
5. If DTC is detected, go to AT-102, "Diagnostic Procedure".

WITH GST
Follow the procedure "With CONSULT-II".

Diagnostic Procedure
1. CHECK FLUID TEMPERATURE SENSOR SIGNAL
With CONSULT-II
1. Start engine.
2. Select "A/T" with "DATA MONITOR" mode in CONSULT-II.








3. Read out the value of "FLUID TEMP SE".

Without CONSULT-II
1. Start engine.








2. Check voltage between TCM connector terminals 41 and 42 while warming up A/T. Refer to "Wiring Diagram-AT-FTSP".
3. Turn ignition switch "OFF".
4. Disconnect the TCM connector.
5. Check if there is continuity between the connector terminal and ground.
OK or NG
OK >>GO TO 6.
NG >>GO TO 2.

2. CHECK FLUID TEMPERATURE SENSOR CIRCUIT
1. Turn ignition switch "OFF".
2. Disconnect the TCM connector.








3. Check resistance between terminals 41 and 42.
4. Check if there is continuity between the connector terminal and ground.
OK or NG
OK >> GO TO 6.
NG >>GO TO 3.

3. CHECK TERMINAL CORD ASSEMBLY WITH A/T FLUID TEMPERATURE SENSOR
1. Turn ignition switch "OFF".
2. Disconnect terminal cord assembly harness connector.








3. Check resistance between terminals 4 and 8.
4. Reinstall any part removed.
OK or NG
OK >>GO TO 4.
NG >>GO TO 5.

4. CHECK HARNESS BETWEEN TCM AND TERMINAL CORD ASSEMBLY
Check the following.
- Open or short-circuit in the harness between TCM and terminal cord assembly.
OK or NG
OK >>GO TO 6.
NG >>Repair or replace damaged parts.

5. CHECK A/T FLUID TEMPERATURE SENSOR
1. Remove side cover. Refer to "Side cover".
2. Disconnect A/T fluid temperature sensor.








3. Check resistance between terminals 4 and 8.
OK or NG
OK >>GO TO 6.
NG >>Repair or replace transmission wire. Refer to "Terminal cord assembly".

6. CHECK DTC
Perform "DTC Confirmation Procedure". Refer to AT-100 "DTC Confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >>GO TO 7.

7. CHECK TCM
1. Check TCM input/output signal. Refer to "TCM Input/Output Signal Reference Values". Pinout Values and Diagnostic Parameters
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> INSPECTION END
NG >>Repair or replace damaged parts.

Component Inspection

A/T FLUID TEMPERATURE SENSOR
1. Remove side cover. Refer to "Side cover".
2. Disconnect A/T fluid temperature sensor.








3. Check resistance between terminals 4 and 8.
4. If NG, repair or replace transmission wire. Refer to "Terminal cord assembly".
