Emissions light/symbol

[hecho.in.626]

Hi everyone. I was hoping to get some advice. The emissions symbol came on in my dash for the first time and I'm not sure if that is an issue that needs to be addressed asap or if it's something that can wait until the weekend. It's on but not blinking. My car is pretty much stock except for some cosmetic upgrades. I do have about 28k in miles. Drove to a buddy's house this afternoon and everything was fine. The emissions light was on when I turned on my car to drive home. I drove home about 15 miles with the light on and everything felt fine.

Any advice would be greatly appreciated!

Update...
Took it my dealer this morning. SA ran a quick diagnostic and said its a faulty pressure sensor and it needs to be replaced. Nothing major. I needed to get to work so he said bring it by this weekend to get it replaced. He estimated it to be a 3 hour job so I will need to get a loaner. Lame.
