DTC P0745 LINE PRESSURE SOLENOID VALVE
Revision: 2006 January2006 M35/M45
DTC P0745 LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionNCS001M3
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.
CONSULT-II Reference ValueNCS001M4
On Board Diagnosis LogicNCS001M5
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P0745 L/PRESS SOL/CIRC” with CONSULT-II or 4th judgement flicker without
CONSULT-II is detected under the following conditions.
–When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
–When TCM detects as irregular by comparing target value with monitor value.
Possible CauseNCS001M6
Harness or connectors
(Solenoid circuit is open or shorted.)
Line pressure solenoid valve
DTC Confirmation ProcedureNCS001M7
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, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T”
with CONSULT-II.
3. Touch “START”.
4. Engine start and wait for at least 5 seconds.
5. If DTC is detected, go to AT-131, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.

In “P” Position, Vehicle Moves When PushedNCS001Q1
SYMPTOM:
Even though the selector lever is set in “P” position, the parking mechanism is not actuated, allowing
the vehicle to be moved when it is pushed.
DIAGNOSTIC PROCEDURE
1. CHECK PNP SWITCH CIRCUIT
Perform self-diagnosis. Refer to AT- 9 2 , "
SELF-DIAGNOSTIC RESULT MODE" , AT- 1 0 3 , "TCM SELF-DIAG-
NOSTIC PROCEDURE (NO TOOLS)" .
Do the self-diagnostic results indicate PNP switch?
YES >> Check malfunctioning system. Refer to AT- 11 3 , "DTC P0705 PARK/NEUTRAL POSITION
SWITCH" .
NO >> GO TO 2.
2. CHECK CONTROL LINKAGE
Check control linkage.
Refer to AT-228, "Checking of A/T Position" .
OK or NG
OK >> GO TO 3.
NG >> Adjust control linkage. Refer to AT-227, "
Adjustment of A/T Position" .
3. CHECK PARKING COMPONENTS
Check parking components. Refer to AT-248, "
REMOVAL AND INSTALLATION (VQ35DE MODELS)"
(VQ35DE models for 2WD), AT-298, "DISASSEMBLY" (VQ35DE models for AWD), AT- 2 5 5 , "REMOVAL AND
INSTALLATION (VK45DE MODELS)" (VK45DE models).
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK A/T FLUID CONDITION
1. Remove oil pan. Refer to AT- 2 3 6 , "
Control Valve With TCM and A/T Fluid Temperature Sensor 2" .
2. Check A/T fluid condition. Refer to AT-53, "
A/T Fluid Condition Check" .
OK or NG
OK >>INSPECTION END
NG >> Check malfunction items. If any items are damaged, repair or replace damaged parts. Refer to AT-
64, "Symptom Chart" (Symptom No.65).

Refer to AT-228, "Checking of A/T Position" .
OK or NG
OK >> GO TO 3.
NG >> Adjust control linkage. Refer to AT-227, "
Adjustment of A/T Position" .
3. CHECK A/T FLUID LEVEL
Check A/T fluid level. Refer to AT-13, "
Checking A/T Fluid" .
OK or NG
OK >> GO TO 4.
NG >> Refill ATF.
4. CHECK A/T FLUID CONDITION
1. Remove oil pan. Refer to AT-236, "
Control Valve With TCM and A/T Fluid Temperature Sensor 2" .
2. Check A/T fluid condition. Refer to AT- 5 3 , "
A/T Fluid Condition Check" .
OK or NG
OK >> GO TO 5.
NG >> Check malfunction items. If any items are damaged, repair or replace damaged parts. Refer to AT-
64, "Symptom Chart" (Symptom No.67).
5. CHECK SYMPTOM
Check again. Refer to AT- 5 7 , "
Check at Idle" .
OK or NG
OK >>INSPECTION END
