P0711
DTC P0711 TRANSAXLE FLUID TEMPERATURE SENSOR RATIONALITYCOMPONENT LOCATION:
GENERAL DESCRIPTION
The automatic TRANSAXLE fluid (ATF) temperature sensor is installed in the Valve Body. This sensor uses a thermistor whose resistance changes according to the temperature changes. The TCM (PCM) supplies a 5V reference voltage to the sensor, and the output voltage.
DTC DESCRIPTION
This DTC code is set when the ATF temperature output voltage is lower than a value generated by thermistor resistance, in a normal operating range, for approximately 1 second or longer. The TCM (PCM) regards the ATF temperature as fixed at a value of 80°C (176°F).

MONITOR SCAN TOOL DATA
1. Connect SCAN TOOL to data link connector (DLC).
2. Engine ON.
3. Monitor the TRANSAXLE FLUID TEMPERATURE SENSOR parameter on the SCAN TOOL.
Specification: Increasing Gradually
Specification:
4. Does TRANSAXLE FLUID TEMPERATURE SENSOR follow the reference data?
YES > Fault is intermittent caused by poor contact in the sensor's and/or TCM (PCM)'s connector or was repaired and TCM (PCM) memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and go to Verification of Vehicle Repair procedure.
NO > Go to Terminal & Connector Inspection procedure.
TERMINAL & CONNECTOR INSPECTION
1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
YES > Repair as necessary and go to Verification of Vehicle Repair procedure.
NO > Go to Component inspection procedure.
COMPONENT INSPECTION
1. CHECK TRANSAXLE FLUID TEMPERATURE SENSOR
1. Ignition OFF.
2. Disconnect the TRANSAXLE FLUID TEMPERATURE SENSOR connector.
3. Measure the resistance between terminals 1 and 2 of the TRANSMISSION FLUID TEMPERATURE SENSOR.
Specification: Refer to Reference data
[REFERENCE DATA]
REFERENCE DATA:
4. Is resistance within specifications?
YES > Go to CHECK TCM (PCM).
NO > Replace TRANSAXLE FLUID TEMPERATURE SENSOR as necessary and Go to Verification of Vehicle Repair procedure.
2. CHECK TCM
1. Ignition ON & Engine OFF.
2. Connect TRANSAXLE FLUID TEMPERATURE SENSOR connector.
3. Install SCAN TOOL and select a SIMU-SCAN.
4. Simulate voltage (0-5V) to TRANSMISSION FLUID TEMPERATURE SENSOR signal circuit.
5. Is FLUID TEMP. SENSOR signal value changed according to simulation voltage?
YE > Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to Verification of Vehicle Repair procedure.
NO > Substitute with a known-good TCM (PCM) and check for proper operation. If the problem is corrected, replace TCM (PCM) as necessary and then go to Verification of Vehicle Repair procedure.
VERIFICATION OF VEHICLE REPAIR
After a repair, it is essential to verify that the fault has been corrected.
1. Connect SCAN TOOL and select Diagnostic Trouble Codes (DTCs) mode.
2. Using a SCAN TOOL, Clear DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are any DTCs present?
YES > Go to the applicable troubleshooting procedure.
NO > System performing to specification at this time.
