My Check Engine Light Went On—Now What?

May 31st, 2018 by

Check Engine Light

There’s one warning light virtually all Collinsville drivers will panic about, but whether it’s a Mazda3 check engine light or a check engine warning on another make or model, the Auffenberg Mazda service center has advice. 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 why a Mazda CX-5, MX-5 Miata, or Mazda3 engine light has come on without investigating your vehicle, but your check engine light could mean one or more of the following:

 

Reason Potential Risks if Unserviced
Oxygen sensor replacement warning
  • Lower fuel economy
  • Spark plug and catalytic converter damage
Loose, damaged, or no gas cap
  • Lower fuel economy
Airflow sensor replacement warning
  • Won’t pass emission test
  • Worse performance and efficiency
Catalytic converter replacement warning
  • Damage to the catalytic converter, oxygen sensors, spark plugs, etc.
  • Worse performance and efficiency
Spark plug replacement warning
  • Worse performance and efficiency
  • Damage to plugs, catalytic converter, oxygen sensors, ignition coils

How to Reset a Check Engine Light

Many of our Fairview drivers have asked us about a Mazda6 or Mazda3 check engine light reset, to just turn the light off, 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.

If you do something that resets your check engine light, you should still bring your vehicle in to have it inspected. The delay between a check engine light reset and the light coming back on could be long enough for significant damage to be caused by whatever problem your car is having.

Why Is My Check Engine Light Flashing?

Depending on your make and model, your check engine light flashing could mean a few different things. Some manufacturers’ lights flash while others stay solid. If you notice the check engine light blinking only when your vehicle starts up, this is usually normal — most of your dashboard lights should turn on and/or blink in the seconds after starting your car. A flashing check engine light could also be an intermittent problem.

In short, if your Mazda3 check engine light is flashing or blinking, you should take it as seriously as if your check engine light is 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. Another option is the on-off method. This method forces the computer to refresh its saved state during the reboot. To do this method:

  • Place your key in the ignition
  • Turn it on for one to two seconds
  • Turn it off for one to two seconds
  • Repeat this step three or four times.

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 Edwardsville who can read the particular system code and investigate what the problem could be.
