What Triggers the Check Engine Light?

The primary purpose of the check engine light is to alert you that your vehicle is in need of maintenance service. The light can indicate that there is a major issue, or it can be something as simple as a loose gas cap. We’ve listed below some of the most common reasons why the check engine light is activated:

• Loose Gas Cap: If the gas cap has not been properly seated, the check engine light will turn on. Check this first, as it is a very easy fix!
• Emission/Catalytic Converter: The catalytic converter takes carbon monoxide and converts it into safer components to reduce pollution. A malfunctioning catalytic converter will negatively influence your gas mileage, and you may also experience poor acceleration.
• Air/Fuel Delivery: The engine requires a balance of air and fuel in order to run properly. If it gets too much or little of either, the control module will trigger the check engine light. Engine performance will be affected and you will also experience reduced fuel economy returns.
• Ignition System: Problems with the spark plugs misfiring or issues with the coil or any other ignition components will cause the check engine light to come on. If this is not addressed promptly, your vehicle may stall or fail to start.

There are many other issues that will activate the check engine light. So, what should you do when the check engine light comes on? It is highly recommended that you bring your vehicle into one of the Sam Leman Automotive Group service centers in Central Illinois as soon as possible and have our experienced technicians diagnose exactly what the problem is.
