Hello,

This sounds like you have a turbine shaft speed sensor that is out. To be sure lets run the codes by following this guide:

Please run down this guide and report back.

Does the power seem down as well? because a plugged catalytic converter can cause this as well due to low vacuum. Even if the check engine light is not on it can still have a code. here are two guides. please run down them and report back.

and

Please let us know what you find. We are interested to see what it is.

Good job on the codes, this car has the CVT transmission which has problems. can you tell is it making any weird sounds also can you check the fluid level and condition? smell the fluid to see if it burnt and check the color. If you have not serviced the unit I would try that as well. here is a guide to walk you through the steps:

Please run down this guide and report back. Can you please shoot a quick video with your phone so we can hear the noise? that would be great. You can upload it here with your response.

Yep, it looks like the transmission is slipping. have you serviced the fluid? If not I would start there. Here is a guide to walk you through the steps with more information in the diagrams below:

https://www.2carpros.com/articles/how-to-service-an-automatic-transmission

CAUTION:
- Use only Genuine NISSAN CVT Fluid NS-2. Do not mix with other fluid.
- Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.
- When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
- Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid. Refer to See: Continuously Variable Transmission/Transaxle, CVT > Scan Tool Testing and Procedures > CONSULT-III Function (Transmission).
4. Check fluid level and condition. Refer to See: Fluid - CVT > Procedures > Inspection.

Check out the diagrams (below). Please let us know what happens.
