The check engine light is the most frustrating dashboard indicator light because there are so many things it could mean, from major problems to small issues. Here are some of the most common causes of the check engine light coming on. If you try a few simple fixes and the light doesn’t go off, you should head to a shop ASAP and have them run a diagnostic test to find out what the problem is.
You could have a loose gas cap, for example. This is a pretty common one that triggers the check engine light. Worn out spark plugs or spark plug wires are also a sign, and while this isn’t the most urgent problem, you will still need to replace them. You may have faulty oxygen sensors, your engine could be wet, or you might have deteriorated fuel injector rings.
Pay attention to your dashboard indicators and see if any other lights have come on in conjunction with the check engine light. Try slowing down and reducing the load on your engine and seeing if that makes the light go off. This isn’t a permanent fix, and you’ll still need to have it checked out, but it’s better to be safe than sorry.
Most of the issues associated with the check engine light are easy and cheap fixes, so see a mechanic and get them repaired as soon as they arise before bigger problems come up!
