Emissions Warning.

I have a 2007 MDX that I purchased used in August of last year. It has a little over 120k on it.. today my gas was low (not ridiculously low) but enough to have my light come on. Anyways. I got gas, and drove it 20 mins, and then on the highway the emissions warning came on. My car is running fine, and I read it could be the gas cap. I tightened it, restarted the car a few times and it’s still on. I’m leaving it overnight, and hoping it will clear on its own.. I also read it could be an O2 sensor, or catalytic converter..does the extreme cold have anything to do with this? The car seems to be running okay..

Without diagnosing we can all just speculate… Is it a base model? tech models with the GPS have on board DTC readings so you can know the exact OBDII code that its showing with that Emission Warning.
