My Check Engine Light Went On—Now What?

August 13th, 2018 by

Check Engine Light

The “check engine light” is one of the few car troubles virtually all Metairie drivers panic about, but the mechanics at the Leson Chevrolet service center are here to help. First: don’t panic. Then:

  1. Pull over to the side of the road or find a parking lot.
  2. Read this guide.
  3. Visit your trusted service center as soon as possible.

Why is My Check Engine Light On?

We can’t answer this specifically until a technician can investigate your vehicle, but these are some of the most common causes for a check engine light to turn on:

Reason

How to Reset a Check Engine Light

Many of our New Orleans drivers have asked us how to reset a check engine light, but that’s not really a question we can answer for two reasons:

  • Resetting a check engine light won’t fix the problem, and it will eventually turn back on.
  • Simply turning off the light means a driver won’t worry as much about fixing a potentially serious problem.

Why is My Check Engine Light Blinking?

Depending on your make and model, your light could be blinking for the same reason someone else’s check engine light could turn on and stay on. It could also be an intermittent problem or something that only occurs during start-up. In short, if your check engine light is flashing or blinking, you should take it as seriously as your check engine light being on.

Can I Troubleshoot My Check Engine Light?

One of the most common reasons the check engine light comes on is a failure to tighten the gas cap well enough, so that’s the first thing you should check. If you’re a good DIY handyperson, then you might be able to take care of some of the other fixes (hopefully with genuine parts), but otherwise it’s a good idea to bring it to a pro near Harvey who can read the particular system code and investigate what the problem could be.

Bring Your Car in For Service Near Harvey
