My Toyota Camry's Check Engine Light is On, What Should I Do?

I recently bought a used Toyota Camry and the check engine light came on. It drives fine, but I'm worried about potential problems. What should I do?

First, don't panic. The check engine light can come on for a variety of reasons, some more serious than others. The best thing to do is to take your car to a trusted mechanic and have them run a diagnostic test. They'll be able to pinpoint the issue and give you an accurate diagnosis.

One common reason for the check engine light to come on is a loose gas cap. Make sure your gas cap is securely tightened, then drive your car for a while and see if the light goes off. If it doesn't, you may need to take it to a mechanic for further inspection.

I had a similar issue with my Camry and it turned out to be a faulty oxygen sensor. I ended up getting it replaced and the check engine light hasn't come on since. It's always best to get it checked out by a professional to ensure your car is running smoothly.
