DTC P1745 LINE PRESSURE CONTROLPFP:31036
DescriptionUCS0063D
The pressure control solenoid valve A (line pressure solenoid valve) regulates the oil pump discharge pres-
sure to suit the driving condition in response to a signal sent from the TCM.
On Board Diagnosis LogicUCS0063E

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “P1745 L/PRESS CONTROL” with CONSULT-II is detected when TCM detects
the unexpected line pressure.
Possible CauseUCS0063F
TCM
DTC Confirmation ProcedureUCS0063G
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
2. Make sure that output voltage of CVT fluid temperature sensor
is within the range below.
ATF TEMP SEN: 1.0 - 2.0 V
If out of range, drive the vehicle to decrease the voltage
(warm up the fluid) or stop engine to increase the voltage
(cool down the fluid)
3. If DTC is detected, go to CVT-163, "
Diagnostic Procedure" .
Diagnostic ProcedureUCS0063H
1. CHECK DTC
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT-II.
3. Erase self-diagnostic results. Refer to CVT-63, "
How to Erase Self-diagnostic Results" .
4. Turn ignition switch OFF, and wait for 10 seconds or more.
5. Start engine.
6. Confirm self-diagnostic results again. Refer to CVT-60, "
SELF-DIAGNOSTIC RESULT MODE" .
Is the
“P1745 L/PRESS CONTROL” displayed?
YES >> Replace TCM. Refer to CVT-9, "Service After Replacing TCM and Transaxle Assembly" .
NO >>INSPECTION END

DTC P1777 STEP MOTOR - CIRCUIT
Revision: June 20062007 Versa
TCM terminals data are reference values, measured between each terminal and ground.
Diagnostic ProcedureUCS0063O
1. CHECK INPUT SIGNALS
With CONSULT-II
1. Start engine.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “TRANSMISSION” with CONSULT-II.
3. Start vehicle and read out the value of “STM STEP”, “SMCOIL
A”, “SMCOIL B”, “SMCOIL C”, and “SMCOIL D”.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2. CHECK HARNESS BETWEEN TCM AND STEP MOTOR
1. Turn ignition switch OFF.
2. Disconnect CVT unit connector and TCM connector.
3. Check continuity between TCM connector terminals and CVT
unit harness connector terminals.
4. If OK, check harness for short to ground and short to power.
5. If OK, check continuity between body ground and CVT assembly.
6. Reinstall any part removed.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.

TRANSAXLE ASSEMBLY
Revision: June 20062007 Versa
4. Remove the four drive plate to torque converter nuts.
NOTE:
Rotate the crankshaft clockwise as viewed from front of engine
for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud.
CAUTION:
For matching marks, use paint. Never damage the drive plate or torque converter.
6. Remove the transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle:

CVT fluid charging pipe

Engine mounting bracket (LH)

Fluid cooler tubes

Air breather hose

Any necessary brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:

When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.

Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.

Do not reuse O-rings and copper washers.

When turning crankshaft, turn it clockwise as viewed from the front of the engine.

When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be
sure to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-37, "
TIMING
CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.

When installing the torque converter to the transaxle measure
distance A.
