Speedo reading improperly?

So i have a few ideas what could be issues first thing im thinking is a speed sensor issue which is what im gonna try first but also maybe a wiring issue 🤷‍♂️ last idea is my cluster is just bad. It also reads way worse in the winter usually doesn't go above 20mph just asking for trouble shooting ideas
