How do you fix your speedometer on your corsa?

To fix the speedometer on your Corsa, first check the vehicle's fuse box for any blown fuses related to the speedometer. If the fuse is intact, inspect the speed sensor located on the transmission, as a faulty sensor can cause speedometer issues. Additionally, ensure that the wiring and connections are secure and free from corrosion. If these steps do not resolve the problem, consider consulting a professional mechanic for further diagnosis and repair.
