What do you do if the odometer on a Nissan Altima does not work?

If the odometer on your Nissan Altima is not working, start by checking the vehicle's fuse related to the instrument panel, as a blown fuse can cause malfunctions. If the fuse is intact, inspect the vehicle speed sensor (VSS), which sends speed data to the odometer. Additionally, you may need to check for any wiring issues or a malfunctioning instrument cluster. If these steps don't resolve the issue, consider consulting a professional mechanic for further diagnosis and repair.
