You need to have the ecm scanned for codes. The VSC and TRAC OFF lights are one just because the Check engine light is on. Once you clear the code in the ecm they will go off too.
Testimonial: "We actually fixed the problem before we got the feedback! I read it could be a loose gas cap, and that was it!!! But thank you anyway!!!"

SOURCE: Check engine and VSC lights on
that the check engine light is on indicates a problem. that the light is not flashing indicates that the computer does not think that the problem is all that bad. without some other vehicle malfunction symptoms best advice i can give you is to take your vehicle to a place that has a code reader and see what codes it has stored. some car parts stores will retrieve the codes for free, idea being that the parts store can then sell you some parts to fix the problem. but you don't have to buy anything, you can just have them read the codes. some of the parts stores will give you a printout of the codes too. get the codes and you know what the computer is not liking, then you can make a more informed decision about what to do next. hope that helps.

Check your switches for the VSC, some get bumped on (due to their location) and some get stuck in the "on"position.
SOURCE: What does the VSC light on the dash mean
VSC means Vehicle Stability Control. Take the car for a scan to ease your mind.

It is not hard to change the sensor, it just screws into a threaded hole. The light will not go out immeditaly, after the sensor is replaced. It needs to go thru a drive cycle. Your best bet is to replace the sensor and get the code cleard by whoever scanned it for the 0031 code.
