DTC P0715

Input/turbine speed sensor circuit malfunction

DETECTION CONDITION

• When all conditions below satisfied and 0.7 second or more have passed.
- D, S or L 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 PCM detects the above malfunction conditions during first drive cycle.
• PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• HOLD indicator light flashes. (4AT)
• AT warning light illuminates. (SPORT AT)
• DTC is stored in the PCM memory.

POSSIBLE CAUSE

• Input/turbine speed sensor malfunction
• Short to ground between input/turbine speed sensor terminal A and PCM terminal 3J
• Short to ground between input/turbine speed sensor terminal B and PCM terminal 3G
• Open circuit between input/turbine speed sensor terminal A and PCM terminal 3J
• Open circuit between input/turbine speed sensor terminal B and PCM terminal 3G
• Damaged connectors between input/turbine speed sensor and PCM
• PCM 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 PCM CONNECTOR FOR POOR CONNECTION

• Disconnect PCM 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

• Inspect input/turbine speed sensor terminals (harness-side) and PCM terminals (harness-side).
- A and 3J
- B and 3G
• 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 (harness-side) and body ground.
- A and body ground
- B 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 PCM, 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.
