Hello, so basically my Nissan maxima (2011) (250 st-l) has a CEL, but when I try to check the error codes with my OBD2 scanner it shows me no codes, it just displays N/A. I was wondering if anyone had any similar experiences and what the causes and fixes were for it. Thanks

 

I haven't had that issue but I did have an issue with my old OBDII scanner. I would suggest you have your local O'Reilly or Auto Zone use their scanner and see if they can get any codes to come up.
