Have a 2012 Nissan Quest emission control light came on what may this be?

Question

Having emission code problem information needed.

Answer 1

HI there,

This means you need to have the computer scanned for codes. The light comes on for a large variety of reasons and one of the monitored systems has a problem. This will turn the light on then you have it scanned, once you have a code then you know where to start looking for the problem. The emission system is made up of several components. I would start by checking the gas cap and making sure it's tight.
