In a Mazda CX-9, if the fuel gauge isn't working, it's likely due to a faulty fuel level sensor located in the gas tank. This sensor measures gasoline levels using a float. A malfunctioning sensor won't relay information to the ECU, causing gauge issues. To troubleshoot, use an OBD II scan tool to check for ECU faults related to the fuel level sensor. If found, replace the sensor with a new one to restore functionality.
