Why is my Ford Ranger's check engine light on?

I noticed that my check engine light came on while driving my Ford Ranger. What could be causing this and how can I fix it?

The check engine light can come on for a variety of reasons, from a loose gas cap to a more serious issue with your engine. I suggest taking your Ford Ranger to a trusted mechanic to have it checked out as soon as possible. In the meantime, make sure your gas cap is securely fastened.

I had a similar issue with my Ford Ranger and it turned out to be a faulty oxygen sensor. It's best to have a professional diagnose the problem so you know exactly what needs to be fixed. Don't ignore the check engine light, as it could lead to bigger problems down the road.

It's possible that your check engine light is on because your spark plugs need to be replaced. This is a fairly simple fix that you can do yourself with the right tools. Check your owner's manual for the proper steps.
