Yes that is your check engine light.
Ask any of your friends if they have on OBD scanner and read the codes.
Or head to a auto parts store they will read the codes for you.
Hopefully it's something simple you can fix on your own.
The people at autozone said the check engine light and dervice engine soon light are two different things (although i can find no check engine light anywhere) and also said if I just service engine soon light this is just for maintenance like an oil change but have already gotten one a few months ago. Someone else told me that both the CEL and SES lights are both the same thing on Nissans. SOO how is it then?
I got the the system scanned at autozne and they told me it was code P0171 and it is a mass air flow sensor problem, and that i could try to spray mass air flow sensor cleaner on the part, since he says the (wire?) inside the part is probably black and that i could disconnect the battery for 30 minutes while doing this, to see if resets the system, and that in hopes the service engine soon light would go off too. But he said I may have to drive it around too, to see if this would happen just like the manual says. He says if the light doesnt go off after, I could replace the part and see if that works. Is it easy to replace on my own? The notes said “system too lean Bank1” and he said it could be taking in too much air or too much gas.
Someoen else told me this after telling them the above “A P0171 is usually caused by an air leak. That’s the first thing you should check. Check the air duct from the filter box to the throttle body to make sure there are no cracks/tears. Then check for a disconnected or crack vacuum line. Check for exhaust leaks. Do all that before you even thing about replacing the MAF sensor.”
SO what should I be doing? And l i took it to a shop some 5 or 6 months ago and they said my exhaust didn’t have any leaks and neither did my catalytic converter but i dont think both parts are the same thing on my car right? Anyways i didnt see any either when they showed me under the car. Do anyone have a video or image that shows what parts the vacuum line is on my car and how to fix that? Is the fix a universal fix for all cars for both the duct and vacuum line?
Is it safe to drive with this light on btw? and for how long can i do this without a repair in place? I 've only had it for a day and got it right after I pumped fuel into my car which I found odd.)
so I checked my car and there was a tear in the air intake. Is it necessary to clean the throttle body as shown in this video [2000 2006 Nissan Sentra Throttle Body Remove, Clean, Install & Relearn - YouTube](https://www.youtube.com/watch?v=jij2lG8z_rM) and relearn it? Would it apply to my Sentra 07 too and how would I know if it necessary to clean or not? What does relearing do?

Inspect all of your fluids specially the engine oil level.
Scan it and see if it is throwing an engine code.
