DTC DETECTION LOGIC
DTC | CONSULT screen terms (Trouble diagnosis content) | DTC detection condition | Possible causes |
P0746 | PRESSURE CONTROL SOLENOID A (Pressure Control Solenoid A Performance/Stuck Off) | The detecting condition A or detection condition
B is detected twice or more (1 second or
more later after detection of the first) in the
same DC under the following diagnosis conditions: Diagnosis conditions
Detection condition A
Detection condition B

NOTE:
DC stands for “DRIVING CYCLE” and indicates a series of driving cycle of “Ignition switch OFF → ON → driving → OFF”.
DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
Selector lever : “D” position
Accelerator pedal position : 0.1/8 or more
Vehicle speed : 40 km/h (25 MPH) or more
Is “P0746”detected? YES >> Go to TM-191, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK LINE PRESSURE SOLENOID VALVE
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK LINE PRESSURE
Perform line pressure test. Refer to TM-149, "Work Procedure".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace the malfunction items.
Component Inspection
1.CHECK LINE PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
Is the inspection
result normal?
YES >> INSPECTION END
NO >> There is a malfunction of line pressure solenoid valve. Replace transaxle assembly. Refer to TM- 283, "Removal and Installation".
