Check engine light is still on even after I fixed the issue

My oil was low and I had no antifreeze so that's why it would heat up fast. As soon as the issue arose I pulled over and refilled them but today is day 2 and it's still the same. The antifreeze did go down halfway when I stopped for gas then I went straight home where I checked it again and it was full. I'm not sure what's going on. All is great today. It runs normally but the engine light won't go away.
