What causes the engine light to turn on in my Ford Focus?

I have noticed that the engine light on my Ford Focus turns on randomly. What could be the potential causes for this issue and how can I fix it?

The engine light can indicate a variety of issues, from minor problems like a loose gas cap to more serious issues such as a faulty sensor. It is best to bring your car to a trusted mechanic to diagnose the specific cause. However, make sure to check your gas cap first before taking it in.

I had a similar problem with my Ford Focus and it turned out to be a faulty oxygen sensor. It's always best to get it checked out as soon as possible to avoid any potential damage to your car's engine.

In some cases, the engine light may turn on due to a loose connection or a weak battery. Double check all connections and consider getting your battery tested to rule out any potential issues.
