DTC P0715 | Turbine sensor circuit malfunction
--- | ---
DETECTION CONDITION | • The following condition is detected twice: – Turbine sensor signal is 300 rpm or less while engine speed is 1,500 rpm or more and vehicle speed is 40 km/h {25 mph} or more in D range for 2 s or more. Diagnostic support note: • This is a continuous monitor (CCM). • MIL illuminates if TCM detects the above malfunction condition during the first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • AT warning light illuminates. • DTC is stored in TCM memory.
POSSIBLE CAUSE | • Turbine sensor malfunction • Short to ground in wiring harness between turbine sensor terminal A and TCM terminal 2G • Open circuit in wiring harness between turbine sensor terminal A and TCM terminal 2G • Open circuit in wiring harness between turbine sensor terminal B and ignition switch (IG1) • Open circuit in wiring harness between turbine sensor terminal C and body ground • Damaged connectors between turbine sensor and TCM • TCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has 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 | INSPECT TURBINE SENSOR CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the turbine sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the connector and terminals normal? | Yes | Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 10.
4 | INSPECT TURBINE SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the ON position (engine off). • Inspect the voltage at turbine sensor connector terminal B. • Is the terminal voltage B+? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
5 | INSPECT TURBINE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Inspect for continuity between the turbine sensor (wiring harness-side) terminal C and body ground. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
6 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the connector and terminals normal? | Yes | Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 10.
7 | INSPECT TURBINE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the turbine sensor (wiring harness-side) terminal A and TCM (wiring harness-side) terminal 2G. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
8 | INSPECT TURBINE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between the turbine sensor (wiring harness-side) terminal A and body ground. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
9 | INSPECT TURBINE SENSOR • Inspect the turbine sensor. (See TURBINE SENSOR INSPECTION.) • Is the turbine sensor normal? | Yes | Go to the next step.
No | Replace the turbine sensor, then go to Step 10. (See TURBINE SENSOR REMOVAL/INSTALLATION.)
10 | VERIFY TROUBLESHOOTING OF DTC P0715 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the WDS or equivalent. • Drive the vehicle with vehicle speed of 40 km/h {25 mph} or more and engine speed of 1,500 rpm or more for 2 s or more. • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION.)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [RC4A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [RC4A-EL].)
No | DTC troubleshooting completed.
