What You Can Do to Troubleshoot

One of the most common reasons the check engine light comes on is a failure to tighten the gas cap well enough, so that’s the first thing you should check. If you’re a good DIY handyperson, then you might be able to take care of some of the other parts replacements, but otherwise it’s a good idea to bring it to a pro.
