DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
Diagnostic Procedure
ECS00987
1.
CHECK VALVE RESISTANCE
1.
Turn ignition switch to “OFF” position.
2.
Disconnect terminal cord assembly connector in engine compartment.
3.
Check resistance between terminal 5 and ground.
OK or NG
OK
>> GO TO 2
NG
>> 1. Remove oil pan. Refer to
.
2. Check the following items:
–
Torque converter clutch solenoid valve
Refer to
AT-164, "Component Inspection"
.
–
Harness of terminal cord assembly for short or open
2.
CHECK POWER SOURCE CIRCUIT
1.
Turn ignition switch to “OFF” position.
2.
Disconnect TCM harness connector.
3.
Check continuity between terminal 5 and TCM harness connector terminal 3.
If OK, check harness for short to ground and short to power.
4.
Reinstall any part removed.
OK or NG
OK
>> GO TO 3
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
3.
CHECK DTC
Perform
AT-161, "DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE"
.
OK or NG
OK
>> INSPECTION END
NG
>> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

DTC P0745 LINE PRESSURE SOLENOID VALVE
DTC P0745 LINE PRESSURE SOLENOID VALVE
PFP:31940
Description
ECS00989
The line pressure solenoid valve regulates the oil pump discharge
pressure to suit the driving condition in response to a signal sent
from the TCM.
NOTE:
The line pressure duty cycle value is not consistent when the
closed throttle position switch is “ON”. To confirm the line
pressure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is
“OFF”.
CONSULT-II REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Specification data are reference values.
NOTE:
The line pressure duty cycle value is not consistent when the closed throttle position switch is “ON”. To confirm the line pressure duty
cycle at low pressure, the accelerator (throttle) should be open until the closed throttle position switch is “OFF”.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE” has been previously conducted,
always turn ignition switch “OFF” and wait at least 5 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1.
Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
2.
Depress accelerator pedal completely and wait at least 1 sec-
ond.
3.
If DTC is detected, go to
AT-169, "Diagnostic Procedure"
.
With GST
Follow the procedure “With CONSULT-II”.
