DTC P0713:00

TFT sensor circuit high input
DETECTION CONDITION
LF, L5
•  The TCM detects that input voltage from the TFT sensor is more than 4.66 V for 1 s when the following condition is met.
―  Time since engine start: more than 180 s
MZR 2.0 DISI i-stop
•  The TCM detects that input voltage from the TFT switch is more than 4.66 V for 1 s when the following conditions are met.
―  Battery positive voltage is 9 V or more
―  Intake air temperature is -31 °C {-23 °F} or more
―  IAT sensor related DTC is not recorded
Diagnostic support note
•  The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle. (LF, L5)
•  The MIL illuminates if the TCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the TCM. (MZR 2.0 DISI i-stop)
•  The AT warning light illuminates if the TCM detects the above malfunction condition during the first drive cycle. (LF, L5)
•  The AT warning light illuminates if the TCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the TCM. (MZR 2.0 DISI i-stop)
•  PENDING CODE is available.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the TCM memory.
POSSIBLE CAUSE
•  Coupler component connector or terminal malfunction
•  Short to power supply in wiring harness between TFT sensor and TCM terminal AA
•  TFT sensor malfunction
•  TCM connector or terminal malfunction
•  Open circuit in wiring harness between TFT sensor and TCM terminal AA
•  Open circuit in wiring harness between TFT sensor and TCM terminal V
•  TCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded on the repair order?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION
•  Switch the ignition off.
•  Disconnect the coupler component connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 8.
No
Go to the next step.
4
INSPECT TFT SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Switch the ignition to ON (Engine off).
•  Measure the voltage between coupler component terminal E (wiring harness-side) and body GND.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
No
Go to the next step.
5
INSPECT TFT SENSOR
•  Inspect the TFT sensor.
•  Is there any malfunction?
Yes
Replace the coupler component, then go to Step 8.
(See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FS5A-EL].)
No
Go to the next step.
6
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition off.
•  Disconnect the TCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 8.
No
Go to the next step.
7
INSPECT TFT SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition off.
•  Inspect for continuity between the following circuits:
―  Coupler component terminal E (wiring harness-side) and TCM terminal AA (wiring harness-side)
―  Coupler component terminal H (wiring harness-side) and TCM terminal V (wiring harness-side)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC using the M-MDS.
•  Perform the following procedure to ensure that the DTC has been resolved:
1.  Start the engine.
2.  Idle the engine for 180 s or more.
•  Is the PENDING CODE same as the DTC present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [FS5A-EL].)
No
Go to the next step.
9
VERIFY NO DTCs ARE PRESENT
•  Perform the “Reading DTCs Procedure”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FS5A-EL].)
No
DTC troubleshooting completed.
