DTC P0715

Input/turbine speed sensor circuit malfunction

DETECTION CONDITION

• While driving vehicle with vehicle speed 42 km/h {26 mph}, input/turbine speed sensor signal is not input for 0.8 s or more.
Diagnostic support note:
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle.
• A PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• The O/D OFF indicator light illuminates.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• Input/turbine speed sensor malfunction.
• Short to ground in wiring harness between input/turbine speed sensor terminal A (wiring harness-side) and PCM terminal 67 (wiring harness-side).
• Short to ground in wiring harness between input/turbine speed sensor terminal B (wiring harness-side) and PCM terminal 93 (wiring harness-side).
• Open circuit in wiring harness between input/turbine speed sensor terminal A (wiring harness-side) and PCM terminal 67 (wiring harness-side).
• Open circuit in wiring harness between input/turbine speed sensor terminal B (wiring harness-side) and PCM terminal 93 (wiring harness-side).
• 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 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
VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT
• Turn the ignition switch to the LOCK position.
• Start engine.
• Access TSS PID using the WDS or equivalent.
- IG ON: 0 rpm
- Idle: Within 600-700 rpm
• Are PID readings within specification?
Yes
Go to the intermittent concern troubleshooting procedure, then go to Step 10.
No
Go to the next step.
4
INSPECT INPUT/TURBINE SPEED SENSOR CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch to the LOCK position.
• Disconnect the input/turbine speed 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 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 253-604 ohms between input/turbine speed sensor terminals (part-side)?
Yes
Go to the next step.
No
Replace the input/turbine speed sensor, then go to Step 10.
6
INSPECT INPUT/TURBINE SPEED SENSOR
• Remove the 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 the next step.
7
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Disconnect the PCM 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 terminals, then go to Step 10.
8
INSPECT INPUT/TURBINE SPEED SENSOR CIRCUIT FOR OPEN CIRCUIT
• Inspect input/turbine speed sensor terminals (wiring harness-side) and PCM terminals (wiring harness-side).
- A and 67
- B and 93
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
9
INSPECT INPUT/TURBINE SPEED SENSOR CIRCUIT FOR SHORT TO GROUND
• Inspect input/turbine speed sensor terminal (wiring harness-side) and body ground.
- A and body ground
- B and body ground
• Is there continuity?
Yes
Repair or replace the wiring harness, then go to the next step.
No
Go to the next step.
10
VERIFY TROUBLESHOOTING OF DTC P0715 COMPLETED
• Make sure to reconnect all the disconnected connectors.
• Clear the DTC from memory using the WDS or equivalent.
• Drive the vehicle with vehicle speed 42 km/h {26 mph} or more for 0.8 s or more.
• Are any DTCs present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
