P0711
DTC P0711 TRANSAXLE FLUID TEMPERATURE SENSOR RATIONALITYCOMPONENT LOCATION:
GENERAL DESCRIPTION
The oil temperature sensor is installed in the valve body and uses a heritor that resistance changes by temperature change. PCM offers 5V as a reference voltage and the output voltage changes according to the ATF's temperature. The oil temperature sensor signal is important information in detecting torque converter clutch operation or non-operation area, the oil temperature sensor's variable controlling and oil pressure's controlling at shifting.
DTC DESCRIPTION
PCM displays this code if it detects the condition for more than 1 second. PCM regards that the ATF's oil temperature is 85°C (185°F) since this code is sensed.

SPECIFICATION
SPECIFICATION:
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 PCM.
NO > Replace TRANSAXLE FLUID TEMPERATURE SENSOR as necessary and go to Verification of Vehicle Repair procedure.
2. CHECK PCM
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?
YES > 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 PCM and check for proper operation. If the problem is corrected, replace 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.
