If your light is on, call us at 773-598-8802 and we’ll help you get it checked.

What the Check Engine Light Means

The check engine light is part of your vehicle’s onboard monitoring system. It turns on when the system detects a problem related to engine performance, emissions, or other key components. In some cases, the issue may be minor. In others, it may need more immediate attention. Because the light can come on for many different reasons, testing is needed to determine the cause.

Common Reasons the Check Engine Light Comes On

There are many possible causes for a check engine light.

Some common ones include:

  • Sensor or electrical issues
  • Fuel system problems
  • Emissions-related concerns
  • Ignition system issues
  • Loose or faulty components

The exact cause can vary depending on the vehicle. A warning light alone doesn’t confirm what needs to be repaired.

What to Do When the Light Turns On

If your check engine light comes on, it’s best not to ignore it.

  • If the light is steady, the vehicle may still drive normally, but it should be checked soon
  • If the light is flashing, it may indicate a more serious issue and the vehicle should be inspected as soon as possible

Even if the vehicle feels fine, the system may be detecting a problem early.

How We Diagnose the Problem

Checking the engine light involves more than just reading a code.

Our process may include:

  • Scanning the vehicle’s system for stored codes
  • Reviewing data from sensors
  • Performing additional testing as needed

Codes and warning lights are starting points. Proper diagnostics help confirm the actual cause before any repairs are recommended. Learn more about our auto diagnostics service for a deeper look at how this process works.
