DTC P0717 [SJ6A-EL]



DTC P0717

Turbine sensor circuit malfunction (open circuit/short circuit)

DETECTION CONDITION

  • When all conditions below are satisfied.

    • D range of TR switch input

    • Vehicle speed signal 12 pulse input

    • Turbine sensor signal not input

    Diagnostic support note:
  • The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle.

  • A PENDING CODE is not available.

  • FREEZE FRAME DATA is available.

  • The AT warning light illuminates.

  • The DTC is stored in the TCM memory.

POSSIBLE CAUSE

  • Turbine sensor malfunction

  • Open circuit between turbine sensor terminal B and TCM terminal 2A

  • Open circuit between turbine sensor terminal A and TCM terminal 2B

  • Short to ground in wiring harness between turbine sensor terminal B and TCM terminal 2A

  • Short to ground in wiring harness between turbine sensor terminal A and TCM terminal 2B

  • Short to power in wiring harness between turbine sensor terminal B and TCM terminal 2A

  • Short to power in wiring harness between turbine sensor terminal A and TCM terminal 2B

  • Damaged connector between turbine sensor and TCM

  • TCM malfunction


Diagnostic procedure

STEP

INSPECTION

ACTION

1

VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
  • Has the FREEZE FRAME DATA been recorded?

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 Bulletins and/or on-line repair 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 TCM CONNECTOR FOR POOR CONNECTION
  • Turn the ignition switch to the LOCK position.

  • Disconnect the TCM connector.

  • Inspect for poor connection at TCM terminals R18 and R7 (such as damaged/pulled-out pins, corrosion).

  • Are terminals normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 13.

4

INSPECT CONTINUITY OF TURBINE SENSOR CIRCUIT
  • Inspect for continuity between the TCM terminals 2A and 2B (wiring harness-side).

  • Is there continuity?

Yes

Go to the next step.

No

Go to Step 7.

5

INSPECT TURBINE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND
  • Inspect for continuity between the TCM terminals (wiring harness-side) and body ground.

    • Terminal 2A and body ground

    • Terminal 2B and body ground

  • Is there continuity?

Yes

Go to the next step.

No

Repair or replace the wiring harness for short to ground, then go to Step 10.

6

INSPECT TURBINE SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY
  • Turn the ignition switch to the ON position (engine off).

  • Measure the voltage at TCM (wiring harness-side) terminals 2A and 2B.

  • Is there 0 V at the TCM wiring harness-side connector terminals?

Yes

Go to the next step.

No

Repair or replace the wiring harness for short to power supply, then go to Step 10.

7

INSPECT TERMINAL TURBINE SENSOR FOR POOR CONNECTION
  • Turn the ignition switch to the LOCK position.

  • Disconnect the turbine sensor connector.

  • Inspect for poor connection at turbine sensor terminals A and B (such as damaged/pulled-out pins, corrosion).

  • Are terminals normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 10.

8

INSPECT TURBINE SENSOR

Yes

Go to the next step.

No

Replace the turbine sensor, then go to Step 10.

(See TURBINE SENSOR REMOVAL/INSTALLATION [SJ6A-EL].)

9

INSPECT TURBINE SENSOR CIRCUIT FOR OPEN CIRCUIT

  • Inspect for continuity between turbine sensor terminals (wiring harness-side) and TCM terminals (wiring harness-side).

    • Terminal B and terminal 2A

    • Terminal A and terminal 2B

  • Is there continuity?

Yes

Go to the next step.

No

Repair or replace the wiring harness for open circuit, then go to the next step.

10

VERIFY TROUBLESHOOTING OF DTC P0717 COMPLETED
  • Make sure to reconnect all the disconnected connectors.

  • Clear the DTC from the memory using the M-MDS.

  • Drive the vehicle in D range and make sure that gears shift smoothly from 1GR to 6GR.

  • Is same DTC present?

Yes

Replace the TCM, then go to the next step.

(See TCM REMOVAL/INSTALLATION [SJ6A-EL].)

No

Go to the next step.

11

VERIFY AFTER REPAIR PROCEDURE
  • Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SJ6A-EL].)

No

Troubleshooting completed.
