If your engine light is on in your vehicle, it indicates that there is a problem with the engine or its related components. The engine light, also known as the check engine light or malfunction indicator lamp (MIL), is part of your vehicle’s onboard diagnostic (OBD) system. It is designed to alert you to potential issues that may affect the performance, emissions, or overall operation of your vehicle.

Here are some steps you can take when your engine light is on:

1. Check for immediate issues: If you notice any unusual symptoms like engine misfiring, a significant loss of power, or strange noises, it’s best to pull over and turn off your vehicle. Continuing to drive with severe symptoms can potentially cause further damage.

2. Check the fuel cap: Sometimes, a loose or faulty fuel cap can trigger the engine light. Ensure that your fuel cap is properly tightened. If it was loose, tighten it and see if the light goes off after a few driving cycles.

3. Check for other warning lights: Take a moment to check if any other warning lights are illuminated on your dashboard. Multiple warning lights may indicate a more severe problem that requires immediate attention.

4. Use an OBD scanner: If the engine light remains on after checking the fuel cap, it’s a good idea to have the vehicle’s OBD system scanned. You can visit an auto parts store or a mechanic who can connect a diagnostic scanner to your vehicle’s OBD port. The scanner will retrieve error codes stored in the system, providing information about the potential issue.

5. Address the issue: Once you have the error codes, you can research them online or consult a professional mechanic to determine the exact problem. Depending on the severity, you might choose to address the issue yourself if it’s within your capabilities or take your vehicle to a trusted mechanic for repairs.

It’s important not to ignore the engine light, as it could indicate a problem that, if left unaddressed, may lead to more significant issues or potential breakdowns.
