Since there are no drivability problems, you may start by trying to erase the code. If the codes come back ON then I suggest changing the engine oil. Dirty engine oil can block the sensor and cause the code to set. If the codes still comes back, then you may have to replace the sensor.

More information about the P0021 code here: Engine-Codes.com | OBD-II Trouble Code P0021 - Intake valve timing control performance (Bank 2)

I agree with Nissan Tech. Also check the oil level.
