Some of the top reasons your check engine light might come on can all be fixed if you take your car to a mechanic right away. If you don’t know what the problem is, most mechanics can help you troubleshoot until they figure it out.
- The issue may be your oxygen sensor. This measures the oxygen in your vehicle’s exhaust system that isn’t burned. If it is damaged and you don’t replace it right away, you could have a problem with your spark plugs or catalytic converter. You may also have bad fuel economy.
- If you lost your gas cap, this could be a reason your check engine light is illuminated. Getting a new cap as soon as possible is advised.
- If your catalytic converter is bad, then your vehicle isn’t converting carbon monoxide into carbon dioxide properly. This means your fuel economy will be worse, your car may be running at a higher temperature, and you probably won’t pass an emissions test!
- You have a mass airflow sensor out. This sensor tells your car how much fuel it needs to run your engine efficiently. It this sensor doesn’t work, you will see damage to your catalytic converter, oxygen sensors, and you will have some reduced performance.
- If you have bad spark plugs or wires, your check engine light will shine. Spark plugs are what ignite the air and fuel, and the wires deliver the spark from the ignition coil to the plugs. If you don’t replace these when they don’t work properly, then you will have less power and use more gas. You can also damage the catalytic converter, ignition coils, and oxygen sensors.
Make sure if your check engine light comes on, you bring your car in to get serviced if you are in or near Ashland, OR. All of these but one (lost gas cap) is a serious situation that can get worse every time you drive it!
