Most drivers dread seeing warning lights illuminated on their dashboards, especially if it’s the check engine light. This indicator is often misunderstood because it could hint at several different—and unrelated—issues in your vehicle as detected by the onboard diagnostics. But even though it seems ominous, some drivers still choose to ignore it, risking severe engine damage in the process. Here’s what you should do once you see it.

What to Do When the Check Engine Light Turns On

1. Check If It’s Steady or Flashing

Before assuming there’s a serious problem, check if the light is flickering or steady. If it stays on, the problem is not severe and won’t immediately affect your car’s drivability. However, you still need to bring your car to a mechanic. But if it’s red and flashing, then you might need to pull over and shut off the engine right away.

2. Look for Other Signs

Some problems require immediate attention, so check other dashboard gauges and lights for signs of overheating or low oil pressure. A flickering light could indicate an engine misfire that may overheat the catalytic converter, resulting in potential fire hazards and costly repairs.

3. Try Tightening the Gas Cap

There are times when the problem might be as simple as a loose or faulty gas cap. Tighten it so the fuel won’t evaporate quickly, causing a reduction in gas mileage and increase in emissions. Continue driving and check if the light turns off after some time.  

4. Reduce Speed & Load

If you notice performance issues as you drive with a blinking check engine light, such as loss of power, slow down and lighten your load to reduce the strain on the engine. Have the problem diagnosed immediately to prevent extensive damage to your vehicle.

5. Have It Diagnosed Professionally

Some car owners try to identify the problem on their own using a handy code reader. However, interpretation of the diagnosis can get tricky, so it’s always better to have your vehicle diagnosed by a professional instead.
