I guess the obvious answer is check it.
A few things to consider: 1. An OBD II scanner to read the trouble code(s) is pretty inexpensive (there are a few choices at around $120). Autozone will check if free for you, except in California.
- The code that comes up may not tell you exactly to what is broken, but it will at least provide a clue to help with the diagnosis.
- If the light coincides with the O2 sensor change, that's a pretty big clue already. For some cars, there are cases where changing brands causes a CEL. Not sure if this ever happens to Subes though. Anyway the new sensor could be bad.
