P2004 code

Read through your warranty when you bought the vehicle what is covered. Your Nissan dealer service department would be able to help as well. I would say no, since that code has to deal with the intake runner control stuck open. An oil change would be unrelated.

I would think this is covered as this affects how the engine runs and the emissions.

What about getting gas. Cause the light came on when I was done filling up and turned the engine back on
