There could be several reasons why the fuel gauge in your Mazda CX5 isn't working. One way to figure out the issue is by using an OBD-2 device to scan your vehicle for fault codes. These codes can provide valuable information about where the problem might be originating from in the fuel system. Common culprits for a faulty fuel gauge include a malfunctioning instrument cluster, a failed sending unit, or a defective fuel tank float. To better pinpoint the cause, it would be helpful to know more details about how and when the problem started - such as whether the gauge is erratic, always showing empty, always showing full, etc. Sharing this information can assist in troubleshooting the issue more efficiently.
