DTC P0715

Input/turbine speed sensor circuit malfunction

DETECTION CONDITION

•  While driving vehicle with vehicle speed 41 km/h {25 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 B and PCM terminal 1M.

•  Short to ground in wiring harness between input/turbine speed sensor terminal A and PCM terminal 1Q.

•  Open circuit in wiring harness between input/turbine speed sensor terminal B and PCM terminal 1M.

•  Open circuit in wiring harness between input/turbine speed sensor terminal A and PCM terminal 1Q.

•  Damaged connectors between input/turbine speed sensor and PCM.

•  PCM malfunction.

DTC P0715	Input/turbine speed sensor circuit malfunction
DETECTION CONDITION	• While driving vehicle with vehicle speed 41 km/h {25 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 B and PCM terminal 1M. • Short to ground in wiring harness between input/turbine speed sensor terminal A and PCM terminal 1Q. • Open circuit in wiring harness between input/turbine speed sensor terminal B and PCM terminal 1M. • Open circuit in wiring harness between input/turbine speed sensor terminal A and PCM terminal 1Q. • 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.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		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 M-MDS. ― 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. (See INTERMITTENT CONCERN TROUBLESHOOTING[L3].)
3		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.
4		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)? (See INPUT/TURBINE SPEED SENSOR INSPECTION[GF4AX-EL].)	Yes	Go to the next step.
5		No	Replace the input/turbine speed sensor, then go to Step 10. (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION[GF4AX-EL].)
6	INSPECT INPUT/TURBINE SPEED SENSOR • Remove the input/turbine speed sensor. • Is there iron powder stuck on input/turbine speed sensor? (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION[GF4AX-EL].)	Yes	Clean input/turbine speed sensor, then go to Step 10
6		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.
7		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). ― B and 1M ― A and 1Q • Is there continuity?	Yes	Go to the next step.
8		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.
9		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 M-MDS. • Drive the vehicle with vehicle speed 41 km/h {25 mph} or more for 0.8 s or more. • Are any DTCs present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[L3].)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[GF4AX-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[GF4AX-EL].)
11		No	DTC troubleshooting completed.
