What causes the Ford Fiesta Check Engine Light to come on?

I have a 2015 Ford Fiesta and recently my check engine light came on. I'm not sure what could be causing this and I'm worried about the cost of repairs. Any advice on what the issue could be?

There are a few common reasons for the check engine light to come on in a Ford Fiesta. It could be a loose gas cap, a faulty oxygen sensor, or an issue with the catalytic converter. My advice would be to take your car to a trusted mechanic and have them run a diagnostic test to determine the exact cause.

I had a similar issue with my 2017 Ford Fiesta and it turned out to be a problem with the mass airflow sensor. I would recommend checking that first before spending money on other potential fixes.

There's no need to panic when the check engine light comes on. It could be something as simple as a faulty oxygen sensor or a loose gas cap. However, it's always best to have a professional check it out to make sure it's not a more serious issue.
