If the check engine light in your Scion TC comes on, it indicates that the vehicle's onboard diagnostic system has detected a problem. Common issues can range from minor problems, like a loose gas cap, to more significant concerns, such as engine misfires or emissions system failures. It's advisable to use an OBD-II scanner to retrieve the trouble codes, which can help pinpoint the issue. If you're unsure or the light persists, consider consulting a mechanic for a thorough diagnosis.
