Why is my Ford Fiesta engine malfunction light on?

I recently purchased a used Ford Fiesta and the engine malfunction light keeps turning on. What could be causing this issue and how can I fix it?

Hi Rachel, the engine malfunction light could be turning on due to a variety of reasons such as a faulty oxygen sensor, loose gas cap, or a problem with the catalytic converter. It's important to get your car checked by a mechanic to determine the exact cause and fix the issue before it gets worse.

Hello Rachel, I had a similar issue with my Ford Fiesta and after getting it checked, it turned out to be a faulty oxygen sensor. I highly recommend getting it fixed as soon as possible as it can affect your car's performance and lead to higher fuel consumption.
