Check Your Gas Cap
One common reason why the Check Engine Light may come on is because your gas cap is loose, damaged, or missing altogether. It may seem like a small thing, but a loose gas cap can cause your car to lose fuel through evaporation, which can lead to lower fuel efficiency and increased emissions.
If your gas cap is not tightened properly, it can also trigger a diagnostic trouble code (DTC) which will turn on the Check Engine Light. Fortunately, this is an easy fix. Simply tighten your gas cap until you hear it click and see that it won't move any more. If your gas cap is damaged or missing, it's important to replace it as soon as possible.

If your Check Engine Light comes on, the first thing you should do is check your other dashboard warning lights. If other warning lights are on, such as the battery or oil pressure light, it may indicate a more serious problem that requires immediate attention.
Even if no other warning lights are on, you should still get your car checked out as soon as possible. Continuing to drive with the Check Engine Light on can cause damage to your car and lead to more expensive repairs down the road.

If your spark plugs are dirty or worn out, you may notice that your engine is misfiring or that your car is running rough. You may also experience a decrease in fuel efficiency or have trouble starting your car. To fix this issue, you'll need to have your spark plugs replaced by a professional mechanic.
What Should You Do if Your Check Engine Light Comes On?
Check Your Oxygen Sensor
One of the most common reasons why the Check Engine Light may come on is because of a problem with your oxygen sensor. Your car's oxygen sensor measures the amount of oxygen in your exhaust, which helps your engine run more efficiently and reduce emissions.
If your oxygen sensor is not working properly, it can cause your engine to run too rich or too lean, which can lead to problems with your car's performance and fuel efficiency. You may notice that your car is running rough, that your fuel economy has decreased, or that the Check Engine Light is on.
To fix this issue, you'll need to have your oxygen sensor replaced by a professional mechanic. Ignoring this problem can lead to more serious issues with your engine and more expensive repairs down the road.
