Your car’s check engine light is designed to provide you with immediate warning of a mechanical issue in your vehicle. If your check engine light illuminates suddenly while you are driving, you will want to bring your car to a trusted automotive repair facility. Your mechanic will use diagnostic tools to inspect your car and figure out why your check engine light has turned on. Let’s review some of the top reasons why your check engine light may be on.

Faulty Oxygen Sensor

Your car’s oxygen sensor is responsible for keeping track of how much oxygen is leaving your car through the exhaust system. If your check engine light has turned on suddenly, a faulty oxygen sensor could be to blame. When your oxygen sensor gets covered in grime or debris from your engine, it may no longer take accurate readings of the oxygen mix in your exhaust system.

Loose Gas Cap

A loose gas cap may also cause your check engine light to turn on. When your gas cap is not screwed on all the way, it can cause gas fumes to enter your fuel lines. In order to preserve the safety and efficiency of your vehicle, you will want to make sure that your gas cap is secured properly at all times.

Broken Catalytic Converter

In the event that your catalytic converter becomes damaged or broken, this could also cause your check engine light to turn on. A broken catalytic converter can cause issues with your car’s acceleration or overall gas mileage.
