3 VERIFY CURRENT INPUT SIGNAL STATUS
•
Turn ignition key to OFF.
•
Connect breakout box to PCM.
•
Turn ignition key to ON (engine OFF).
•
Measure the voltage at PCM terminal 3D.
•
Are voltage readings above 0.06 V ?
Yes Go to intermittent concern troubleshooting procedure.
(See F–227 INTERMITTENT CONCERN
TROUBLESHOOTING .)
No Go to next step.
4 INSPECT TERMINAL CONDITION
•
Turn ignition key to OFF.
•
Disconnect ATX connector.
•
Inspect for bent terminals.
•
Are the terminals bent?
Yes Repair or replace terminals, then go to Step 9.
•
If terminals cannot be repaired, replace harness, then
go to Step 9.
No Go to next step.
5 INSPECT TFT SENSOR CIRCUIT
•
Turn ignition key to ON (engine OFF).
•
Verify if voltage changes to 4.67 V or above at
PCM terminal 3D when ATX connector
disconnected.
•
Does voltage change?
Yes Go to next step.
No Go to Step 8.
6 INSPECT TFT SENSOR TERMINALS
CONDITION
•
Turn ignition key to OFF.
•
Disconnect TFT sensor connector.
•
Inspect for bent TFT sensor terminals.
•
Are the terminals bent?
Yes Repair terminals or replace TFT sensor, then go to Step 9.
(See K–21 TRANSAXLE FLUID TEMPERATURE (TFT)
SENSOR REMOVAL/INSTALLATION .)
No Go to next step.
7 INSPECT TFT SENSOR CIRCUIT FOR SHORT
TO GROUND
•
Inspect for continuity between TFT sensor
terminals (harness-side) and body ground.
— A and body ground
— B and body ground
•
Is there continuity?
Yes Repair or replace harness, then go to Step 9.
No Replace TFT sensor, then go to step 9.
(See
K–21 TRANSAXLE FLUID TEMPERATURE (TFT)
SENSOR REMOVAL/INSTALLATION .)
8 INSPECT ATX CONNECTOR CIRCUIT FOR
SHORT TO GROUND
•
Turn ignition key to OFF.
•
Inspect for continuity between ATX connector
terminal E (vehicle harness-side) and body
ground.
•
Is there continuity?
Yes Repair or replace harness, then go to next step.
No Go to next step.
9 VERIFY TROUBLESHOOTING OF DTC P0712
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.
10 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.
STEP INSPECTION ACTION
DTC P0713 Transaxle fluid temperature (TFT) sensor circuit malfunction (open circuit)
DETECTION
CONDITION
•
If PCM detects either of following conditions for 150 seconds or more , PCM determines that TFT sensor
circuit has a malfunction.
— TFT sensor voltage is
4.67 V or above and vehicle speed 20 km/h {12 mph} or above .
Diagnostic support note:
•
This is a continuous monitor (CCM).
•
MIL illuminates if PCM detects the above malfunction conditions during first drive cycle.
•
PENDING CODE is not available.
•
FREEZE FRAME DATA is available.
•
HOLD indicator light flashes.
•
DTC is stored in the PCM memory.
