Why is the check engine light in my Ford Galaxy on?

I recently purchased a used Ford Galaxy and have noticed that the check engine light is on. I'm not sure what could be causing this and I'm worried it could be a major issue. Any advice on what I should do?

First, don't panic. The check engine light can be triggered by a variety of issues, some of which are minor and easily fixable. The best course of action would be to take your Ford Galaxy to a trusted mechanic and have them run a diagnostic test to determine the exact cause of the light. They will be able to advise you on the necessary steps to take to resolve the issue.

The check engine light could be on due to something as simple as a loose gas cap. Make sure to check that first before taking it to a mechanic. If that doesn't solve the issue, then it's best to get it checked out to avoid any potential problems in the future.
