DTC P0745 LINE PRESSURE SOLENOID VALVE
DescriptionINFOID:0000000003532316
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.
The line pressure duty cycle value is not consistent when the closed throttle position signal is “ON”.
To confirm the line pressure duty cycle at low pressure, the accelerator (throttle) should be open until
the closed throttle position signal is “OFF”.
CONSULT-II Reference Value in Data Monitor ModeINFOID:0000000003532317
On Board Diagnosis LogicINFOID:0000000003532318
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0745 L/PRESS SOL/CIRC” with CONSULT-II is detected under the following con-
ditions.
- 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 CauseINFOID:0000000003532319
• Harness or connectors
(The solenoid circuit is open or shorted.)
• Line pressure solenoid valve
DTC Confirmation ProcedureINFOID:0000000003532320
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” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
2. Engine start and wait at least 5 second.
3. If DTC is detected, go to AT-115, "
Diagnosis Procedure".
WITH GST
Follow the procedure “With CONSULT-II”.
