If the RPM gauge isn't functioning in your Honda Civic, it's likely due to a sensor issue within the engine. Several sensors detect the engine's rotational speed, and any of them could be faulty. There's a possibility that the ECU isn't transmitting data from a sensor to your tachometer. To troubleshoot, consider using an OBD II scan tool to check for any computer glitches when the tachometer malfunctions. While a failed tachometer motor could also be the culprit, this scenario is less probable and may warrant replacement.

The main reason why the RPM gauge in a Honda Civic stops working is typically due to a blown fuse associated with the tachometer. Check the fuses to ensure they are in good condition. In addition to that, a faulty tachometer relay switch or improper wiring could also be to blame for a malfunctioning tachometer.
