5 INSPECT TFT SENSOR CIRCUIT
• Turn ignition key to ON (engine OFF).
• Measure the voltage at PCM terminal 3D when
connect between ATX connector terminals E
and H (vehicle harness-side) using jumper
wire.
• Verify that voltage changes to 0.06 V or below.
• Does voltage change?
Yes Go to next step.
No Go to Step 8.
6 INSPECT TFT SENSOR CONNECTOR FOR
POOR CONNECTION
• Turn ignition key to OFF.
• Remove valve body cover.
• Disconnect TFT sensor connector.
• Check for poor connection (damaged/pulled-
out terminals, corrosion, etc.).
• Is connection okay?
Yes Go to next step.
No Repair or replace connector and/or terminal or replace TFT
sensor, then go to Step 11.
(See K21 TRANSAXLE FLUID TEMPERATURE (TFT)
SENSOR REMOVAL/INSTALLATION.)
7 INSPECT TFT SENSOR CIRCUIT FOR OPEN
• Check for continuity between TFT sensor
terminals (harness-side) and ATX connector
terminals (transaxle case side).
 ATX connector terminal E and TFT sensor
terminal A
 ATX connector terminal H and TFT sensor
terminal B
• Is there continuity?
Yes Replace TFT sensor, then go to Step 11.
(See K21 TRANSAXLE FLUID TEMPERATURE (TFT)
SENSOR REMOVAL/INSTALLATION.)
No Repair or replace harness, then go to Step 11.
8 INSPECT PCM CONNECTOR FOR POOR
CONNECTION
• Turn ignition key to OFF.
• Disconnect PCM connector.
• Check for poor connection (damaged/pulled-
out terminals, corrosion, etc.).
• Is connection okay?
Yes Go to next step.
No Repair or replace connector and/or terminal, then go to
Step 11.
9 INSPECT HARNESS FOR OPEN CIRCUIT
• Disconnect ATX connector.
• Connect the PCM connector.
• Turn ignition key to ON (engine OFF).
• Inspect voltage at ATX connector terminal E
(vehicle harness-side).
• Is voltage 5 V?
Yes Go to next step.
No Repair or replace harness, then go to Step 11.
10 INSPECT ATX CONNECTOR CIRCUIT FOR
OPEN
• Turn ignition key to OFF.
• Inspect continuity between ATX connector
terminal H (vehicle harness-side) and body
ground.
• Is there continuity?
Yes Go to next step.
No Repair or replace harness, then go to next step.
11 VERIFY TROUBLESHOOTING OF DTC P0713
COMPLETED
• Make sure to reconnect all disconnected
connectors.
• Clear DTC from memory using WDS or
equivalent.
• Drive vehicle under following condition for 150
seconds or more.
 Vehicle speed (VSS PID) 20 km/h {12 mph}
or above.
• Is same DTC present?
Yes Replace PCM, then go to next step.
(See F43 PCM REMOVAL/INSTALLATION.)
No Go to next step.
12 VERIFY AFTER REPAIR PROCEDURE
• Perform After Repair Procedure.
(See K52 AFTER REPAIR PROCEDURE.)
• Are any DTCs present?
Yes Go to applicable DTC inspection.
No Troubleshooting completed.
