I got a check engine light for the 2nd time now. When it happened the first time it was on for a few mins then it went away but the VSC lights stayed on. I drove it again on Saturday and it's on again. Here's what my code reader says.

How do I tell if it's my Cat or O2 sensor? Does any of this info from the reader help?

This might help you understand and troubleshoot the issue, if you haven't seen it already.
