DTC P0745 LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionUCS005P7
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-II Reference ValueUCS005P8
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005P9

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0745 LINE PRESSURE S/V” with CONSULT-II or 11th judgement flicker with-
out CONSULT-II is detected when TCM detects an improper voltage drop while it tries to operate the sole-
noid valve.
Possible CauseUCS005PA

Harness or connector
(The solenoid circuit is open or shorted.)

Line pressure solenoid valve
DTC Confirmation ProcedureUCS005PB
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-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Touch “START”.
3. Depress accelerator pedal completely and wait at least 1 sec-
ond.
4. If the check result is NG, go to AT-147, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
WITHOUT CONSULT-II
1. Start engine.
2. With brake pedal depressed, shift the lever from “P” → “N” → “D” → “N” → “P” positions.
3. Perform self-diagnosis. Refer to AT- 9 0 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT-147, "
Diagnostic Procedure" .
