1. Check your gas cap. A loose or missing gas cap can cause your check engine light to come on. Make sure the gas cap is tight and secure.
2. Check your oil level. Low oil can also cause your check engine light to come on. Check your oil level and add oil if necessary.
3. Have your car scanned for diagnostic trouble codes. If you've checked the gas cap and oil level and the check engine light is still on, you can have your car scanned for diagnostic trouble codes. This will tell you what's causing the light to come on.
4. Fix the problem that's causing the light to come on. Once you know what's causing the check engine light to come on, you can fix the problem and turn the light off.
5. Reset your car's computer. Once you've fixed the problem, you can reset your car's computer. This will turn the check engine light off.
If you can't fix the problem yourself, you should take your car to a mechanic. They will be able to diagnose the problem and fix it.
