Default Anyone know what this is about?

Ok, I've done a search and see that some have had the CEL, VSC, & VSC OFF lights come on. Could be the TPS, but my car runs fine when I hit the pedal. Could be an O2 sensor, a possibility! Could be a tranny solenoid, cause I have the PI TC. Also could be the speed sensor at a wheel, as well.

I am taking the car into the dealership on Friday for service anyway, but curious if what has happened to my car has happened to anyone else. I got into my car on Friday after work and noticed upon leaving the parking garage, that the lights were on. I pulled over, shut the car off and turned it on, lights came back. Now this is how the lights come on, note the sequence. CEL comes on first, staying on after the car is started. Then 5 seconds later, both the VSC and VSC OFF come on. So this Sat I set up the service call, since I was meaning to anyway. Well now this AM, the lights are on. Make my daily stop at Dunkin Donuts, start the car and the lights have gone off. I thought this would happen, but on Friday when this problem happened not now. So I turned the car off and restarted, lights stay off.

Now when I leave work in about 3 hrs, does anyone think the lights will come back? HAHA Any thoughts on what may be causing this? I will surely update the cause when it goes in on Friday. Least I have my VSC back, so it can snow this week, lol! Thanks for the comments and suggestions in advance guys!
