What Does the Check Engine Light Mean?

The check engine light, also known as the check engine lamp, engine check warning, or engine indicator light, is part of your vehicle’s onboard diagnostics system. It lights up when your car’s computer detects a potential issue with the engine, emissions system, or other vital components.

For German vehicles, this light is especially sensitive. Something as simple as a loose gas cap or as serious as a failing catalytic converter can trigger it.

Common causes include:

  • Faulty oxygen sensors
  • Worn-out spark plugs
  • Mass airflow sensor failure
  • Failing ignition coils
  • Emission system issues

No matter the reason, the light is your vehicle’s way of saying, “Hey, let’s get this checked.”

Why You Shouldn’t Ignore It

We get it—life gets busy, and if your car seems to be running fine, it’s tempting to put off a visit. But ignoring your check engine light in Oceanside, CA, could mean letting a small issue snowball into expensive repairs or even engine damage.

Driving with a lit engine indicator light may also:

  • Lower fuel efficiency
  • Cause your car to run poorly
  • Increase emissions
  • Create safety risks

Our advice? Don’t wait. Bring it in as soon as possible for a professional check engine light check.
