What the Check Engine Light Means
The check engine light, also known as the malfunction indicator lamp (MIL), is part of your vehicle's on-board diagnostics (OBD) system. When the light illuminates, it means the OBD system has detected a problem with one or more of the components that control or monitor your vehicle's engine, transmission, or emissions. The light can indicate anything from a loose gas cap to a more serious issue like a malfunctioning catalytic converter.
How to Respond to the Check Engine Light
- Don't ignore the light. The check engine light is a warning that something is wrong and needs to be addressed.
- Scan the system. Use an OBD-II scanner to read the diagnostic trouble codes stored in your vehicle's computer. This will help identify the specific problem.
- Address the issue. Once you know the cause, take your vehicle to a qualified mechanic to have the problem diagnosed and repaired.
- Reset the light. After the repairs are made, the mechanic will reset the check engine light. If the light comes back on, it means the underlying problem has not been fully addressed.
Ignoring the check engine light can lead to more serious and costly problems down the road. By addressing the issue promptly, you can save yourself time, money, and potential safety concerns.
