P0745

P0745 PRESSURE CONTROL SOLENOID A

Description

- Line pressure solenoid valve is installed to control valve.
- Line pressure solenoid valve adjusts oil pump discharge pressure to optimum level according to the driving conditions.
- The adoption of an N/H type (normal high) line pressure solenoid valve enables generation of a control oil pressure when a voltage is not applied to the coil.

- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT
1.Start the engine.
2.Drive the vehicle for 10 seconds or more.
3.Stop the vehicle.
4.Select "Self Diagnostic Results" in "TRANSMISSION".
With GST
Follow the procedure "With CONSULT".
Is "P0745" detected?
YES- Go to .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK LINE PRESSURE SOLENOID VALVE CIRCUIT

1.Turn ignition switch OFF.
2.Check resistance between TCM connector terminal and ground.





Is the inspection result normal?
YES- Check intermittent incident. Intermittent Incident.
NO- GO TO 2.

2. CHECK LINE PRESSURE SOLENOID VALVE

1.Disconnect CVT unit connector.
2.Check Line pressure solenoid valve. .
Is the inspection result normal?
YES- GO TO 3.
NO- Line pressure solenoid valve is malfunctioning. Replace transaxle assembly. Exploded View.

3. CHECK HARNESS BETWEEN TCM AND CVT UNIT (LINE PRESSURE SOLENOID VALVE) (PART 1)

1.Disconnect TCM connector.
2.Check continuity between TCM vehicle side harness connector terminal and CVT unit vehicle side harness connector terminal.





Is the inspection result normal?
YES- GO TO 4.
NO- Repair or replace damaged parts.

4. CHECK HARNESS BETWEEN TCM AND CVT UNIT (LINE PRESSURE SOLENOID VALVE) (PART 2)

Check continuity between TCM vehicle side harness connector terminal and ground.





Is the inspection result normal?
YES- Check intermittent incident. Intermittent Incident.
NO- Repair or replace damaged parts.


Component Inspection (Line Pressure Solenoid Valve)


1. CHECK LINE PRESSURE SOLENOID VALVE

Check resistance between CVT unit harness connector terminal and ground.





Is the inspection result normal?
YES- INSPECTION END
NO- Line pressure solenoid valve is malfunctioning. Replace transaxle assembly. Exploded View.
