Your check engine light appears when part of your vehicle needs some attention.

No automobile repair service is too big or too small for our dedicated team of mechanics. Here are some common reasons your check engine light might come on:
Vacuum System Issues
Your vehicles vacuum system serves several different purposes. Your brake booster is operated by a vacuum, for example. But your vacuum system is also used to keep harmful emission levels down by filtering the fumes that are generated when fuel evaporates within your engine. Sometimes, your vacuum system can experience a leak which renders it unable to perform these vital tasks within your engine. Vacuum leak repairs are a relatively simple car or truck service, however, if left unchecked a leaking vacuum could lead to bigger problems.
Oxygen Sensor Malfunction
The oxygen sensor in your car is responsible for detecting the presence of oxygen together with carbon dioxide being released through your vehicles exhaust. When the sensor registers oxygen, it will regulate your fuel in such a way that combustion is increased to help avoid engine jerking. If your oxygen sensor fails, your car may still seem to be running normally. However, you may soon find that you're experiencing fuel efficiency issues as your vehicle runs through gas at a faster pace. What's worse, certain components within your engine, such as your catalytic converter, might begin to deteriorate.
A Loosened Fuel Cap
That's right, sometimes your check engine light might come on for something as simple as a loose fuel cap. When you pump gas into your vehicle, you may accidently leave your fuel cap on too loose, or neglect to close it at all. When that happens, your check engine light might come on as a way to warn you that you need to tighten your fuel cap properly. Other times, your fuel cap may be worn to the point that it does not tighten appropriately. In this instance, simply swapping your fuel cap should take care of the problem. If a loose fuel cap is the cause of your check engine light coming on, you can easily remedy the problem yourself without the need of an auto repair service professional.
Spark Plug Malfunction or Malfunction
Your vehicle relies on your spark plugs to ignite properly. Spark plugs emit electricity that initiates an ignition that is needed for combustion and the burning of fuel. Spark plugs can go bad over time, causing them to lose their ability to generate the high volt electricity needed for them to work appropriately. When this happens, you will typically notice that your car or truck vibrates when you come to a stop light or if you're in slow traffic. In some cases, your vehicle may spontaneously shut down together. Looking into your check engine light correct away could help you avoid these problems. Your trusted mechanic at AI and Sons can quickly replace your worn spark plugs to make sure you're not left stranded at a stop light.
Another problem that might cause your check engine light to come on is damage to the wires attached to your spark plugs. Like the spark plugs themselves, these wires can become worn and need changing to keep up engine performance.
Mass Airflow Sensor
You mass airflow sensor is different from your oxygen sensor but still performs a vital purpose in your vehicle. This sensor is responsible for measuring the total about of air that enters into the combustion chamber of your engine. From there, it will determine the proper air to fuel ration necessary for your engine to run smoothly. When this part of your engine fails, it could lead to issues with your spark plugs, oxygen sensor, and catalytic converter. Other than your check engine light, you may not know that your mass airflow sensor is experiencing a problem until further occurs.

Carbon monoxide is incredibly harmful to the environment, so your catalytic converter converts it into carbon dioxide instead. If you are good about getting routine maintenance performed on your car or truck, you will likely never have a problem with your catalytic converter.
