Question about 2008 Scion Xd
There are a ton of reasons the light could have come on. If you don't notice anything it might be just an emissions problem, but it should be scanned to at least see what Diagnostic Trouble Codes are stored. The OBD2 connector inside the vehicle can be scanned with a simple code reader that costs $50-$100, but that doesn't always tell you what's the proper repair is, just helps narrow things down to what you need to look at.

The check engine light may come on because of a sensor malfunction, a misfire, excessive heat in the transmission (transmission temp is not included in the engine temp gague) or even just not tightening the fuel cap all the way.
autozone offers free check engine light diagnostics for most vehicles, so that they can sell you sensors and such. most check engine light issues are engine sensor malfunctions, and may not adversely affect the running of the vehicle. many sensor issues can be ignored if you are low on funds at the moment. if it is a fuel cap issue, you will simply need to have the check engine light reset.
a transmission overheat is somewhat of an immediate issue to be resolved, and a misfire is usually a sign of a signifigant problem in the near future, so it would be much worth your time to get a diag test for the check engine code to rule out a tranny temp or misfire issue.

the check engine light comes
on for multiple reasons. My check engine light came on for a messed up oxygen
meter. It could be many reasons that you can't see from just looking at the
engine. I would go get it checked out before it becomes a more serious and/or
