DTC P0745 LINE PRESSURE SOLENOID VALVE
DTC P0745 LINE PRESSURE SOLENOID VALVE
DescriptionINFOID:0000000001327221
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-III Reference Value in Data Monitor ModeINFOID:0000000001327222
On Board Diagnosis LogicINFOID:0000000001327223
Diagnostic trouble code “P0745 L/PRESS SOL/CIRC” with CONSULT-III or 4th judgement flicker without
CONSULT-III 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 CauseINFOID:0000000001327224
Harness or connectors (Solenoid circuit is open or shorted.)
Line pressure solenoid valve
DTC Confirmation ProcedureINFOID:0000000001327225
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “MAIN SIGNALS” in “DATA MONITO R” mode for “TRANSMISSION” with CONSULT-III.
3. Touch “START”.
4. Engine start and wait at least 5 seconds.
5. If DTC is detected, go to “ AT-128, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
Diagnosis ProcedureINFOID:0000000001327226
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Turn ignition switch ON.
2. Select “MAIN SIGNALS” in “DATA MONITO R” mode for “TRANSMISSION” with CONSULT-III.
3. Start engine.
4. Read out the value of “LINE PRES SOL” while driving.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2.CHECK TCM POWER SUPPLY AND GROUND CIRCUIT
Check TCM power supply and ground circuit. Refer to AT-160
.
