DTC P0715, P0717, P0718 [5R55S]

id0502c1806200

DTC P0715

Turbine shaft speed (TSS) sensor malfunction

DTC P0717

Turbine shaft speed (TSS) sensor signal is not input.

DTC P0718

Turbine shaft speed (TSS) sensor signal noise
DETECTION CONDITION
•  P0715: TCM detects insufficient TSS sensor signal while driving
•  P0717: TCM detects that TSS sensor is not input while driving
•  P0718: TCM detects intermittent TSS sensor signal input while driving
POSSIBLE CAUSE
•  TSS sensor malfunction.
•  Short to ground in wiring harness between TSS sensor terminal A (wiring harness-side) and TCM terminal AP (wiring harness-side).
•  Open circuit in wiring harness between TSS sensor terminal A (wiring harness-side) and TCM terminal AP (wiring harness-side).
•  Open circuit in wiring harness between TSS sensor terminal B (wiring harness-side) and TCM terminal AH (wiring harness-side).
•  Damaged connectors between TSS 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 SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT TSS SENSOR CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch to the LOCK position.
•  Disconnect the TSS sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is the connection normal?
Yes
Go to the next step.
No
Repair or replace connector and/or terminal, then go to Step 8.
4
INSPECT TSS SENSOR CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between TSS sensor connector A (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 8.
No
Go to the next step.
5
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Disconnect the TCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is the connection normal?
Yes
Go to the next step.
No
Repair or replace the connector and/or terminals, then go to Step 8.
6
INSPECT TSS SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Inspect the following TSS sensor terminals (wiring harness-side) and TCM terminals (wiring harness-side):
―  A and AP
―  B and AH
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 8.
7
INSPECT TSS SENSOR
•  Inspect the TSS sensor.
•  Is TSS sensor normal?
Yes
Go to the next step.
No
Replace the TSS sensor, then go to the next step.
(See TURBINE SHAFT SPEED (TSS) SENSOR REMOVAL/INSTALLATION [5R55S].)
8
VERIFY TROUBLESHOOTING OF DTC P0715, P0717 OR P0718 COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC from memory using the IDS/PDS.
•  Perform the “After Repair Procedure”.
•  Are any DTCs present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [5R55S].)
No
Go to the next step.
9
VERIFY DTCS
•  Are DTCs except for P0715, P0717 and P0718 output?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [5R55S].)
No
DTC troubleshooting completed.
