How do I troubleshoot my Vauxhall Vivaro's check engine light?

I recently noticed that the check engine light on my Vauxhall Vivaro has turned on. I've checked all the fluid levels and they seem to be fine. What could be causing this and how can I fix it?

Firstly, don't panic. The check engine light can indicate a range of issues, some more serious than others. The best course of action is to take your Vivaro to a certified mechanic and have them run a diagnostic check on the engine. This will give you a specific error code and help pinpoint the issue.

One common cause of the check engine light is a loose or faulty gas cap. Make sure the gas cap is securely tightened and try driving for a few miles to see if the light turns off. If not, there may be a more serious issue at hand and you should take your vehicle to a mechanic.

Another possible cause of the check engine light is a faulty oxygen sensor, which can affect the performance and fuel efficiency of your Vivaro. This is a relatively simple and inexpensive fix, so it's best to get it checked out sooner rather than later.
