DTC P0715 [JA5A-EL]


DTC P0715	Input/turbine speed sensor circuit malfunction
DETECTION CONDITION	• If the following condition is detected twice, the TCM determines that there is a malfunction.: - The input/turbine speed sensor signal is 600 rpm or less while the engine speed is 1,500 rpm or greater and vehicle speed is 40 km/h {24.8 mph} or greater in the D, S, or L range. Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the TCM detects the above malfunction conditions in two consecutive drive cycles. • PENDING CODE is available. • FREEZE FRAME DATA is available. • The HOLD indicator light flashes. • 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 B and TCM terminal 1N • Short to ground in wiring harness between input/turbine speed sensor terminal A and TCM terminal 2F • Open circuit in wiring harness between input/turbine speed sensor terminal B and TCM terminal 1N • Open circuit in wiring harness between input/turbine speed sensor terminal A and TCM terminal 2F • Damaged connectors between input/turbine speed sensor and TCM • TCM malfunction


STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME PID 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.
2		No	Go to the next step.
3	INSPECT TERMINAL COMPONENT NO.2 (8-PIN) CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the terminal component No.2 (8-pin) connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal?	Yes	Go to the next step.
3		No	Repair or replace the terminals, then go to Step 12.
4	INSPECT INPUT/TURBINE SPEED SENSOR RESISTANCE • Measure the resistance between the terminal component No.2 (8-pin) (transaxle case side). • Is the resistance within 513-627 ohms between terminal component No.2 (8-pin) terminal E and F (transaxle case side)?	Yes	Go to the next step.
4		No	Go to Step 8
5	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal?	Yes	Go to the next step.
5		No	Repair the terminals, then go to Step 12.
6	INSPECT TERMINAL COMPONENT NO.2 (8-PIN) CIRCUIT FOR OPEN CIRCUIT • Inspect the terminal component No.2 (8-pin) terminals (wiring harness-side) and TCM terminals (wiring harness-side). - F and 2F - E and 1N • Is there continuity?	Yes	Go to the next step.
6		No	Repair or replace the wiring harness, then go to Step 12.
7	INSPECT TERMINAL COMPONENT NO.2 (8-PIN) CIRCUIT FOR SHORT TO GROUND • Inspect the terminal component No.2 (8-pin) terminal (wiring harness-side) and body ground. - F and body ground - E and body ground • Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 12.
7		No	Go to Step 12.
8	INSPECT COUPLER COMPONENT (8-PIN) CONNECTOR FOR POOR CONNECTION • Disassemble the control valve body cover. • Disconnect the coupler component (8-pin) connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal?	Yes	Go to the next step.
8		No	Repair the terminals, then go to Step 12.
9	INSPECT INPUT/TURBINE SPEED SENSOR RESISTANCE • Measure the resistance between coupler component (8-pin) (transaxle case side). • Is the resistance within 513-527 ohms between coupler component (8-pin) terminal B and A (part side)?	Yes	Repair or replace terminal component, then go to Step 12.
9		No	Go to the next step.
10	INSPECT INPUT/TURBINE SPEED SENSOR CONNECTOR FOR POOR CONNECTION • Disassemble the transaxle. • Disconnect the input/turbine speed sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal?	Yes	Go to the next step.
10		No	Repair the terminals, then go to Step 12.
11	INSPECT INPUT/TURBINE SPEED SENSOR RESISTANCE • Measure the resistance between input/turbine speed sensor. • Is the resistance within 513-627 ohms between input/turbine speed sensor connector terminal A and B (part side)?	Yes	Repair or replace the coupler component, then go to the next step.
11		No	Replace the input/turbine speed sensor, then go to the next step.
12	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 at a vehicle speed of 40 km/h {25 mph} or above and engine speed 1,500 rpm or above for 2 s or more • Repeat Step ii two times. • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [JA5A-EL].)
12		No	Go to the next step.
13	VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [JA5A-EL].)
13		No	DTC troubleshooting completed.
