Instead of wasting time trying to detect a random problem, it is recommended to take the vehicle to a mechanic who can use an OBD tool to identify the trouble code and pinpoint the issue. Checking the gas cap and fuel door is advised as a missing cap or open door can trigger the light unnecessarily. Deal with obvious problems first before seeking professional help to avoid unnecessary trips to the mechanic.
