DTC P0715

Input/turbine speed sensor circuit malfunction

DETECTION CONDITION
•  When all conditions below are satisfied and 0.7 s or more have passed.
―  D range of TR switch input
―  Driving vehicle at vehicle speed of 41 km/h {25 mph} or more
―  Input/turbine speed sensor signal not input
Diagnostic support note:
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the TCM detects the above malfunction conditions during the first drive cycle.
•  The PENDING CODE is available if the TCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA is available.
•  The AT warning light illuminates.
•  The DTC is stored in the TCM memory.
POSSIBLE CAUSE
•  Input/turbine speed sensor malfunction
•  Short to ground in wiring harness between input/turbine speed sensor terminal A and TCM terminal Y
•  Short to ground in wiring harness between input/turbine speed sensor terminal B and TCM terminal AB
•  Open circuit in wiring harness between input/turbine speed sensor terminal A and TCM terminal Y
•  Open circuit in wiring harness between input/turbine speed sensor terminal B and TCM terminal AB
•  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 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
•  Turn the ignition switch to the LOCK position.
•  Start the engine.
•  Measure the frequency of input/turbine speed sensor using a oscilloscope.
―  IG ON: 0 Hz
―  Idle: Within 320—374 Hz (P, N position)
•  Are frequencies of input/turbine speed sensor within specifications?
Yes
Go to the intermittent concern troubleshooting procedure.
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 the connector and/or terminals, then go to Step 10.
5
INSPECT INPUT/TURBINE SPEED SENSOR RESISTANCE
•  Measure the resistance between the input/turbine speed sensor terminals (part-side).
•  Is the resistance within 250—600 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 input/turbine speed sensor.
•  Is there iron powder stuck on input/turbine speed sensor?
Yes
Clean the input/turbine speed sensor, then go to Step 10.
No
Go to the next step.
7
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 10.
8
INSPECT INPUT/TURBINE SPEED SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Inspect the following input/turbine speed sensor terminals (wiring harness-side) and TCM terminals (wiring harness-side):
―  A and Y
―  B and AB
•  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 the memory using the M-MDS.
•  Drive the vehicle a vehicle speed 41 km/h {25 mph} or more for 0.7 s or more.
•  Is the same DTC present?
Yes
Replace the TCM, 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.
