The “Check Engine” light is your vehicle’s way of telling you that something isn’t working quite right under the hood. While it doesn’t always signal an emergency, it should never be ignored. Here’s what you need to know:
Possible Causes Range from Minor to Serious
The light can come on for a variety of reasons, including:
- Loose or damaged gas cap (one of the most common causes)
- Oxygen sensor or mass airflow sensor failure
- Worn spark plugs or ignition issues
- Catalytic converter problems
- Emissions system malfunctions
- Transmission or fuel system issues
Why You Shouldn’t Ignore It
Even if your vehicle seems to be running fine, driving with the “Check Engine” light on can lead to more serious and costly repairs down the road. It may also reduce fuel efficiency or affect emissions.
What to Do Next
When the light comes on, here’s what we recommend:
- Check your gas cap. Make sure it’s tightened properly—it might fix the issue.
- If the light stays on or starts flashing, schedule a diagnostic check immediately.
- A flashing light often indicates a more urgent problem, like a misfire that could damage your catalytic converter.
