The check engine light is a warning light that appears on your dashboard when your car’s computer detects a problem with the engine or emissions system. The light can be yellow, orange, or red, and it will usually stay on until the problem is fixed.

What Should I Do If My Check Engine Light Is On?

If you see your check engine light come on, it’s important to take action as soon as possible. Here are some steps you can follow:

1. Check your owner’s manual. The manual will have information about what the check engine light could mean and what you should do.
2. Take your car to a mechanic. A mechanic can use a diagnostic tool to read the trouble codes that are stored in your car’s computer. These codes will help the mechanic identify the problem and make recommendations for repairs.
3. Don’t ignore the check engine light. If you ignore the check engine light, the problem could get worse and cause more damage to your car. In some cases, ignoring the check engine light could even void your car’s warranty.
