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”.
