Question about 2009 Nissan Murano
P0746: Solenoid A malfunction code.
Pressure Control Solenoid Performance or Stuck Off
This is internal to the transmission and needs repair. Likely a line pressure issue, and the vehicle will not shift until it is repaired. This requires a repair AND an ECM flash/reprogram....
see the following...
DTC P0746 PRESSURE CONTROL SOLENOID A PERFORMANCE (LINE PRESSURE
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
On Board Diagnosis Logic
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.
Line pressure control system
Output speed sensor (Secondary speed sensor)
Input speed sensor (Primary speed sensor)
Unfortunately - this will require a new transmission
P0868: Transmission fluid pressure low (related to the above issue.)
I hope you have a warranty :)

Hi! May I ask if you tried resetting the PCM (powertrain control module)? Used to have a client with the same issue and the cure was to reset the PCM. If no luck on the PCM reset then the problem will be on the PCM itself, you will have to replace it for it to work. But since its a 2008 model I believe that the PCM wont be faulty, a reset may do the trick. Please do write back on the progress. Hope this helps and have a good one!
