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 2K • Short to ground in wiring harness between input/turbine speed sensor terminal B and TCM terminal 2I • Open circuit in wiring harness between input/turbine speed sensor terminal A and TCM terminal 2K • Open circuit in wiring harness 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 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. (See INTERMITTENT CONCERN TROUBLESHOOTING [L8, LF, L3].)
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)? (See INPUT/TURBINE SPEED SENSOR INSPECTION [FS5A-EL].) | Yes | Go to the next step.
No | Replace the input/turbine speed sensor, then go to Step 10. (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION [FS5A-EL].)
6 | INSPECT INPUT/TURBINE SPEED SENSOR • Remove input/turbine speed sensor. • Is there iron powder stuck on input/turbine speed sensor? (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION [FS5A-EL].) | 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 2K - B and 2I • 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 WDS or equivalent. • 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. (See TCM REMOVAL/INSTALLATION [FS5A-EL].)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [FS5A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection.
No | DTC troubleshooting completed.
