Why Is My Check Engine Light On with an Emissions Warning?

The check engine light on my Kia Grand Carnival has come on, but there are no performance problems o r obvious issues. Could it be related to emissions components like the O₂ sensor, catalytic converter, o r a loose fuel cap? I’d like to know how to accurately diagnose this in Pakistan—what tests should be run, and which parts are most commonly failing?
