Troubleshooting a Check Engine Light on a Ford Transit Custom

I recently noticed that the check engine light on my Ford Transit Custom has turned on. What could be the cause of this and how can I fix it?

The check engine light can indicate a variety of issues, but the most common are related to the engine's emission control system. I suggest checking your gas cap first, as a loose or damaged cap can trigger the light. If that doesn't fix it, it's best to take your Transit Custom to a certified mechanic for a diagnostic test.

The check engine light could also be caused by a faulty oxygen sensor, which can affect your vehicle's fuel efficiency and lead to costly repairs in the long run. It's best to have a trained technician check and replace the sensor if needed.

Another possibility is a malfunctioning catalytic converter, which is responsible for reducing harmful emissions. If this is the case, it's important to have it inspected and replaced by a professional as soon as possible.
