Thank You.!
But i Knew that all.!
wanna know where The P0846 Code issue located.?
And how to fixed,Solve is all.!
Please help.!
Code is for the Secondary Pressure transducer as
@Swiftab mentioned. It's most likely a DTC P0840 or P0841 Transmission Fluid Pressure Sens/Switch A. The generic OBDII code readers can falsely identify the wrong code but it's generally the same component. It's located inside the CVT oil sump pan within the valvebody unit. The SM states basically (2) options: 1) Replace the Valvebody (or Pressure transducer) 2) Replace CVT transmission. There are other troubleshooting paths but this is the summary of it unless you feel like checking all of the grounds paths and wiring harness connections then you need the SM for the CVT transmission to proceed further.
So, this would explain the vehicle performance issues your experiencing as the sensor is not working properly. The pressure sensor itself can be found online seperately for a JF011E (RE0F10A or RE0F10B) and Sonnax sell them as well or check Ebay/Alibaba as they are everywhere. New or remanufactured valvebody are also available as well but I'd start there. Finally, the reman CVT are the most expensive option. You still need a very skilled mechanic to do the diagnosis/repair, clear DTC codes, clutch relearn, or TCM reflash depending on what is replaced. This requires a CVT specialist or Nissan dealership but CVT are common enough now that techs know the procedures.
Keep in mind while you keep driving the vehicle you are going to be doing further damage to the CVT. Most healthy CVT don't throw these DTC codes and generally when they do most of the CVT are already heavily damaged but you can proceed how you want to.
Does that answer your questions?
