Hi i got p0011 code on my 06 altima and engine make a noice if i pass 2000rpm whats the resoan ?

Question

Engine vibration is also there.

Answer 1

P0011 IVT Control

This code condition would also put the engine is a fail safe mode, where there is limited acceleration. This would also create a rough idle , but a engine noise? That a concerning issue, such as low oil  pressure, Is the l oil pressure light illuminated? Because this code being set would be from low oil pressure . One of the rule for this code is either check that the oil light is not illuminated, before replace the IVT solenoid.
