How do I troubleshoot my Ford Ranger's engine light?

I recently noticed that the engine light on my Ford Ranger has been on for a few days now. Is there anything I can do to troubleshoot this issue before taking it to a mechanic? I'm worried it might be a sign of a major problem. Thank you in advance for your advice.

I had a similar issue with my Ford Ranger and ended up changing the oil and air filter, and the light went off. You can also try checking for any loose connections or dirty sensors.

It could be something as simple as a loose gas cap causing the light to turn on. Make sure to check that first before bringing it in for repairs.
