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

STEP

INSPECTION

ACTION

1

• 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 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

• 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 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 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

• 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

• 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 the turbine sensor.

  (See TURBINE SENSOR INSPECTION [SJ6A-EL].)

• Is the turbine sensor normal?

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

• 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

• Perform the “After Repair Procedure”.

  (See AFTER REPAIR PROCEDURE [SJ6A-EL].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SJ6A-EL].)

No

Troubleshooting completed.
