It could be a minor issue or something more serious which requires immediate attention. Either way, it's very important to take note of the CEL and get your car checked out as soon as possible.
 
Ignoring the check engine light can lead to much bigger problems down the road, so it's always best to err on the side of caution. If the light doesn’t go away after checking out these top tips, your next step will be to book an appointment with a trusted mechanic.
 

5 quick fixes for when the check engine light comes on

 
The check engine light is a signal that your car's computer has detected a problem. It could be something as simple as a loose gas cap, or it could be something more serious. The best way to find out is to take your car to a mechanic and have them run a diagnostic test.
 
If the problem is something simple, there's a chance you can fix it yourself. Let's explore the 5 best case scenarios for when your check engine light comes on:
 
1. Tighten the gas cap - This is one of the most common causes for the check engine light to illuminate on your dash, and it's usually as simple as making sure the cap is tight and secure.
 
2. Check the air filter - If the air filter is dirty or clogged, it can cause the engine to run poorly and trigger the check engine light. Changing or cleaning the air filter can often fix this problem.
 
3. Replace the spark plugs - If any of the spark plugs in your vehicle are old or worn out, they can cause engine problems, and trigger the check engine light. Replacing them can often solve the issue.
 
4. Add fuel system cleaner - If your car has been running rough or misfiring, it could be due to a dirty fuel system. Adding fuel system cleaner can help to clean out gunk and dirt from the system and restore performance. Ensure that you do some research and determine if this is the best option for your vehicle. 
 
5. Turn your car off and then back on - this will reboot your car's computer.

There few simple solutions above are some great DIY options before taking it in for a check-up. But if you're not sure what's wrong, don't hesitate to speak with the pros.
