Default Murano that won't move and code P0746

Yesterday morning my Mo went into limp mode and threw a P0746 code.
After I parked, it will not move any more, the engine just dies when I put it in gear. I cleared the code but the cvt still is dead. HAs anyone been through this?? I saw the one post that explained what the code means. and posible causes. I was wondering if anyone has had this problem and had it fixed.
Or can help locating and testing the components like the input and output speed sensors and the cvt solinoids.

Default P0746

Here is what is in the Nissan Repair Manual for P0746. The dealer does have some repairs for the CVT solenoid and then they reprogram the ECM. Most likely, they will have to see your Murano.
Good Luck!

DTC P0746 PRESSURE CONTROL SOLENOID A PERFORMANCE (LINE PRESSURE
SOLENOID VALVE)
PFP:31941

Description
ACS002IZ

The pressure control solenoid valve A (line pressure solenoid valve) regulates the oil pump discharge pressure
to suit the driving condition in response to a signal sent from the TCM.
NOTE:
CONSULT-II screen terms are shown differently depending on the version of CONSULT-II card.
CONSULT-II Reference Value
ACS004Y7

Remarks: Specification data are reference values.
On Board Diagnosis Logic
ACS002J0


This is an OBD-II self-diagnostic item.


Diagnostic trouble code “L/PRESS SOL/FNCTN” with CONSULT-II or P0746 without CONSULT-II is
detected under the following conditions.

Unexpected gear ratio was detected in the LOW side due to excessively low line pressure.

Possible Cause
ACS002J1


Line pressure control system


Output speed sensor (Secondary speed sensor)


Input speed sensor (Primary speed sensor)

DTC Confirmation Procedure
ACS002TA

CAUTION:

Always drive vehicle at a safe speed.


Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 5 seconds before performing the next test.

After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to confirm
the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
2. Start engine and maintain the following conditions for at least 10
consecutive seconds. Test start from 0km/h (0 MPH).
ATF TEMP SEN: 1 - 2V
ACC PEDAL OPEN: More than 1.0/8
Selector lever: D position
VHCL SPEED: 10 km/h (6 MPH) More than
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.

I own a 2004 Murano that is now at the dealer awaiting special attention from a tech rep . I believe I have the same problem , when you put it into drive and step on the gas pedal it dies . i noticed this problem and notified the dealer approximatley 4 months after i purchased it. the dealers said it was that I had not been used to driving this new type of transmission. it was noted and today i am glad I brought it too their attention. the service tech said i need a new trans at approx 4500 to 5 thousand. does this sound right to any of you out there!!!!!

Sounds like your problem started slow! Mine was always fine and then went to never moving again within 20 miles. The Dealer told me that they have very little info on these trannies, they checked the solinoid pack then ordered a new trans. Just got it back thursday. Rolling again!!
