What to Do When Your Engine Light Comes On

Your car’s engine light flickers on as you’re cruising down the road, and your heart sinks a little. What now? That little amber light, often shaped like an engine or labelled “Check Engine,” is a warning that something might be wrong under the hood. But before you panic, here’s a step-by-step guide on what to do when your engine light comes on.

1. Don’t Ignore It

First things first—don’t ignore the light. While it might be tempting to brush it off as a glitch or something minor, the engine light is your car’s way of telling you that something needs attention. Ignoring it can lead to more serious, and often more expensive, problems down the road.

2. Check for Obvious Issues

Before you rush to the mechanic, take a moment to see if there’s an obvious issue you can spot yourself. Here are a few things to check:

• Fuel Cap: A loose or damaged gas cap is one of the most common reasons for the engine light to come on. If you’ve recently filled up your tank, make sure the gas cap is tightly secured. If it’s damaged, consider replacing it.
• Dashboard Indicators: Are there other warning lights on the dashboard? Low oil pressure or overheating could be more serious issues that require immediate attention.

3. Assess the Situation

If the engine light is steady and there are no other signs of trouble (like strange noises, smoke, or loss of power), it’s usually safe to continue driving for a short period. However, if the light is flashing, this indicates a more severe issue, such as a misfire that could damage the catalytic converter. In this case, you should pull over safely and call for assistance.

4. Use an OBD-II Scanner

For those who like to take a hands-on approach, an OBD-II scanner can be a useful tool. This device can read the error codes from your car’s computer, giving you more insight into what might be wrong. Once you have the code, you can look up what it means or discuss it with your mechanic.

5. Schedule a Diagnostic Appointment

Even if the issue seems minor or the light goes off after tightening the Fuel cap, it’s still a good idea to have a professional check your vehicle. The engine light can be triggered by a wide range of issues, from minor to major, and only a qualified mechanic can give you a definitive answer. Book a mechanic to perform a thorough diagnostic check and address the root cause of the problem.

6. Don’t Delay Repairs

Once the issue has been identified, make sure to follow through with the necessary repairs. Delaying them can lead to more significant damage, lower fuel efficiency, and ultimately, a more costly visit to the mechanic.

7. Regular Maintenance is Key

Preventive maintenance is your best defence against the engine light coming on in the first place. Regular oil changes, timely filter replacements, and keeping up with your vehicle’s maintenance schedule can help keep your car running smoothly and minimize the chances of unexpected issues.

Conclusion

The engine light is your car’s way of asking for help. When it comes on, it’s important to take it seriously, but there’s no need to panic. By checking for obvious issues, assessing the situation, and scheduling a diagnostic appointment with a trusted mechanic, you can address the problem promptly and keep your car in top shape.
