DTC P0715

Input/turbine speed sensor circuit malfunction

DETECTION CONDITION

• When all conditions below are satisfied and 0.7 second or more have passed.
- D range of TR switch input.
- Driving vehicle with vehicle speed 40 km/h {25 mph} or above.
- Input/turbine speed sensor signal not input.
Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if TCM detects the above malfunction conditions during first drive cycle.
• PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• AT warning light illuminates.
• DTC is stored in the TCM memory.

POSSIBLE CAUSE

• Input/turbine speed sensor malfunction.
• Short to ground between input/turbine speed sensor terminal A and TCM terminal 2K.
• Short to ground between input/turbine speed sensor terminal B and TCM terminal 2I.
• Open circuit between input/turbine speed sensor terminal A and TCM terminal 2K.
• Open circuit between input/turbine speed sensor terminal B and TCM terminal 2I.
• Damaged connectors between input/turbine speed sensor and TCM.
• TCM malfunction.

Diagnostic procedure

STEP

INSPECTION

ACTION

1

VERIFY FREEZE FRAME DATA HAS BEEN RECORDED

• Has FREEZE FRAME PID DATA been recorded?
Yes
Go to next step.
No
Record FREEZE FRAME PID DATA on repair order, then go to next step.
2

VERIFY RELATED REPAIR INFORMATION AVAILABILITY

• Check for related Service Bulletins availability.
• Is any related repair information available?
Yes
Perform repair or diagnosis according to available repair information.
• If vehicle is not repaired, go to next step.
No
Go to next step.
3

VERIFY CURRENT INPUT SIGNAL STATUS

• Turn ignition key to OFF.
• Start engine.
• Measure frequency of input/turbine speed sensor using a oscilloscope.
- IG ON: 0 Hz
- Idle: Within 320-374 Hz (P, N position)
• Are frequency of input/turbine speed sensor readings within specifications?
Yes
Go to intermittent concern troubleshooting procedure.
No
Go to next step.
4

INSPECT INPUT/TURBINE SPEED SENSOR CONNECTOR FOR POOR CONNECTION

• Turn ignition key to OFF.
• Disconnect input/turbine speed sensor connector.
• Check for poor connection (damaged/pulled-out terminals, corrosion, etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminals, then go to Step 10.
5

INSPECT INPUT/TURBINE SPEED SENSOR RESISTANCE

• Measure resistance between input/turbine speed sensor terminals (part-side).
• Is resistance within 250-600 ohms between input/turbine speed sensor terminals (part-side)?
Yes
Go to next step.
No
Replace input/turbine speed sensor, then go to Step 10.
6

INSPECT INPUT/TURBINE SPEED SENSOR

• Remove input/turbine speed sensor.
• Is there iron powder stuck on input/turbine speed sensor?
Yes
Clean input/turbine speed sensor, then go to Step 10.
No
Go to next step.
7

INSPECT TCM CONNECTOR FOR POOR CONNECTION

• Disconnect TCM connector.
• Check for poor connection (damaged/pulled-out terminals, corrosion, etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminals, then go to Step 10.
8

INSPECT INPUT/TURBINE SPEED SENSOR CIRCUIT FOR OPEN CIRCUIT

• Inspect input/turbine speed sensor terminals A (harness-side) and TCM terminals 2K (harness-side).
• Inspect input/turbine speed sensor terminals B (harness-side) and TCM terminals 2I (harness-side).
• Is there continuity?
Yes
Go to next step.
No
Repair or replace harness, then go to Step 10.
9

INSPECT INPUT/TURBINE SPEED SENSOR CIRCUIT FOR SHORT TO GROUND

• Inspect input/turbine speed sensor terminal A (harness-side) and body ground.
• Inspect input/turbine speed sensor terminal B (harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace harness, then go to next step.
No
Go to next step.
10

VERIFY TROUBLESHOOTING OF DTC P0715 COMPLETED

• Make sure to reconnect all disconnected connectors.
• Clear DTC from memory using WDS or equivalent.
• Drive vehicle with vehicle speed 40 km/h {25 mph} or above for 0.7 second or more.
• Is same DTC present?
Yes
Replace TCM, then go to next step.
No
Go to next step.
11

VERIFY AFTER REPAIR PROCEDURE

• Perform "After Repair Procedure".
• Are any DTCs present?
Yes
Go to applicable DTC inspection.
No
Troubleshooting completed.
