P0745 PRESSURE CONTROL SOLENOID A
DescriptionINFOID:0000000005397324
The line pressure solenoid valve regulates the oil pum p 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 po sition switch is ON. To
confirm the line pressure duty cycle at low-pressure, the accelerator (throttle) sh ould be open until the
closed throttle position switch is OFF.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000005397325
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397326
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0745 PC SOLENOID A” with CO NSULT-III or 11th judgement flicker without CON-
SULT-III is detected when TCM detects an improper volt age drop while it tries to operate the solenoid valve.
Possible CauseINFOID:0000000005397327
• Harness or connector
(The solenoid circuit is open or shorted.)
• Line pressure solenoid valve
DTC Confirmation ProcedureINFOID:0000000005397328
CAUTION:
If performing this “DTC Confirmati on 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-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Depress accelerator pedal completely and wait at least 1 second.
4. If the check result is NG, go to AT-135, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
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-82, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-135, "
Diagnosis Procedure" .

Diagnosis ProcedureINFOID:0000000005397330
1.CHECK INPUT SIGNALWith CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Read out the value of “LINE PRES DTY” while driv ing. Check the value changes according to driving
speed.
Without CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM connector terminals and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2.CHECK DROPPING RESISTOR
1. Turn ignition switch OFF.
2. Disconnect dropping resistor har ness connector in engine room.
3. Check resistance between terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
3.CHECK VALVE RESISTANCE
1. Turn ignition switch OFF.
2. Disconnect terminal cord assembly connector in engine room.
