My Check Engine Light Is On

By Sunrise Chevrolet | October 22nd, 2018

Customers from Carol Stream to Bloomingdale often contact us in a panic when saying, “My check engine light is on!” This small light can lead to huge headaches for many drivers, but there’s no need to fear. The issue could be a bad catalytic converter, but it could also be as simple as a loose gas cap. Let’s go into some of the most common reasons that this pesky light makes itself known.

What is a Check Engine Light?

The check engine light was created to instantly alert the driver if something is wrong under the hood. This system was standardized back in 1996 with a formal system of diagnostic trouble codes. That means that any dealership with the right equipment can hook your vehicle up to a reader and find the issue quickly. In fact, you can even take the DIY approach by purchasing a code reader yourself. While you’ll still need to take the car into the shop, customer code readers can help you diagnose your car’s issues as soon as you notice the light.

Why Does the Check Engine Light Matter?

The check engine light indicates that something is wrong with your vehicle and requires immediate attention. If your check engine light is a steady amber glow, then you should schedule an appointment with the dealership as soon as possible. If you notice a check engine light flashing on your dashboard, then you need to move faster. A flashing light is your car’s signal that there are serious issues that need to be resolved, like engine misfires. Do not delay if you notice this warning sign!

What are the Common Causes for a Check Engine Light?

  • Emissions system issues
  • Loose gas cap
  • Problems with the catalytic converter
  • Errors with the airflow sensor
  • Faulty spark plug wires

And while it may seem obvious, we recommend double-checking your dashboard to make sure that the check engine light is really on. Many drivers mistake the “service required” light on the gauge cluster for the check engine light!
