Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397848
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0725” with CONSULT-III is detected when TCM does not receive the engine
speed signal (input by CAN communication) from ECM.
Possible CauseINFOID:0000000005397849
Harness or connectors
(The ECM to the TCM circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005397850
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and maintain the following conditions for at least 10 consecutive seconds. PRI SPEED SEN: More than 1000 rpm
3. If DTC is detected, go to CVT-81, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005397851
1. CHECK DTC WITH ECM
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELF-DIAG RESULTS” mode for “ENGINE” with CONSULT-III. Refer to EC-612, "
CONSULT-III
Function (ENGINE)".
OK or NG
OK >> GO TO 2.
NG >> Check the DTC detected item. Refer to EC-612, "
CONSULT-III Function (ENGINE)".
2. CHECK DTC WITH TCM
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELF-DIAG RESULTS” mode for “TRA NSMISSION” with CONSULT-III. Refer to CVT-48, "

3. CHECK INPUT SIGNALS
With CONSULT-III
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
3. While monitoring “ENG SPEED SIG”, check for engine speed change corresponding to “ACC PEDAL
OPEN”.

Component Description".
4. CHECK DTC
Perform CVT-81, "
DTC Confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.
5. CHECK TCM
1. Check TCM input/output signals. Refer to CVT-46, "
TCM Terminal and Reference Value".
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> INSPECTION END
NG >> Repair or replace damaged parts.

P0740 TORQUE CONVERTER
DescriptionINFOID:0000000005397858
• The torque converter clutch solenoid valve is included in the control valve assembly.
• The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehi-
cle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.
• Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
• When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

- TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Possible CauseINFOID:0000000005397861
• Torque converter clutch solenoid valve
• Harness or connectors (Solenoid circuit is open or shorted.)
