DTC P0745 LINE PRESSURE SOLENOID VALVE
DescriptionINFOID:0000000001694348
The line pressure solenoid valve regulates the oil pump 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 position switch is ON. To
confirm the line pressure duty cycle at low-pressure, the accelerator (throttle) should be open until the
closed throttle position switch is OFF.

Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001694350
 This is an OBD self-diagnostic item.
 Diagnostic trouble code “P0745 LINE PRESSURE S/V” with CONSULT-III or 11th judgement flicker without
CONSULT-III is detected when TCM detects an improper voltage drop while it tries to operate the solenoid
valve.

6. Apply compressed air into the oil hole on transaxle case as
shown to raise piston while strongly pressing the whole low &
reverse brake piston by hand. When applying compressed air,
strongly press the whole piston and adjust the pressure so that it
is raised evenly. Portion (A) (low & reverse brake pressure)
especially tends to tilt.
CAUTION:
Apply air gradually and allow low & reverse brake piston to
come out evenly.
7. Remove low & reverse brake piston from transaxle case by turn-
ing it.
8. Inspect transaxle case. Replace if damaged or worn.
9. Remove seal ring (1) and D-ring (2) from low & reverse brake
piston (3).
INSPECTION
Low & Reverse Brake Snap Rings
Check for deformation, fatigue or damage. Replace if necessary.
Low & Reverse Brake Drive Plates
 Check facing for burns, cracks or damage. Replace if necessary.
 Measure thickness of facing.
CAUTION:
 Measure the thickness at 3 locations and find the average.
 Inspect ALL drive plates.
 Replace if the thickness is below the allowable limit.

Work FlowINFOID:0000000001728326
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelera-
tor pedal position sensor (throttle position sensor) or PNP switch.
Then provides shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-III (or GST) or a circuit tester connected should be
performed. Follow the “DETAILED FLOW”.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic work sheet” as shown on
the example (Refer to TM-327
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.

TCM FunctionINFOID:0000000001714311
The function of the TCM is to:
 Receive input signals sent from various switches and sensors.
 Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
 Send required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The automatic transaxle senses vehicle operating conditions through various sensors or signals. It always
controls the optimum shift position and reduces shifting and lock-up shocks.
