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”.

Large Shock (“N” to “D” Position)NCS001Q3
SYMPTOM:
A noticeable shock occurs when the selector lever is shifted from “N” to “D” position.
DIAGNOSTIC PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Perform self-diagnosis. Refer to AT- 9 2 , "
SELF-DIAGNOSTIC RESULT MODE" , AT- 1 0 3 , "TCM SELF-DIAG-
NOSTIC PROCEDURE (NO TOOLS)" .
Is any malfunction detected by self-diagnostic results?

LINE PRESSURE TEST" .
OK or NG
OK >> GO TO 8.
NG - 1 >> Line pressure high: GO TO 6.
NG - 2 >> Line pressure low: GO TO 7.
6. DETECT MALFUNCTIONING ITEM
1. Check control valve with TCM. Refer to AT- 2 3 6 , "
Control Valve With TCM and A/T Fluid Temperature Sen-
sor 2" .
2. Disassemble A/T. Refer to AT-298, "
DISASSEMBLY" .
3. Check the following.
