DTC P0745 LINE PRESSURE SOLENOID VALVE
DescriptionINFOID:0000000001694348
The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in
response to signals sent from the TCM.
The line pressure duty cycle value is not constant 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-III Reference Value in Data Monitor ModeINFOID:0000000001694349
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001694350
 This is an OBD self-diagnostic item.
 Diagnostic trouble code “P0745 LINE PRESSURE S/V” with CONSULT-III or 11th judgement flicker without
CONSULT-III is detected when TCM detects an improper voltage drop while it tries to operate the solenoid
valve.
Possible CauseINFOID:0000000001694351
 Harness or connector
(The solenoid circuit is open or shorted.)
 Line pressure solenoid valve
DTC Confirmation ProcedureINFOID:0000000001694352
CAUTION:
If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode for “A/T” with CONSULT-III.
2. Touch “START”.
3. Depress accelerator pedal completely and wait at least 1 second.
4. If the check result is NG, go to TM-81, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Start engine.
2. With brake pedal depressed, shift the lever from “P”→“N”→“D”→“N”→“P” positions.
3. Perform self-diagnosis. Refer to TM-38, "
Diagnosis Procedure without CONSULT-III".
4. If the check result is NG, go to TM-81, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001694354
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-III.
3. Read out the value of “LINE PRES DTY” while driving. Check the value changes according to driving
speed.
