What are the reasons for the Kia K5 tachometer not moving?

The reasons why the Kia K5 tachometer is not moving are: 1. The tachometer is damaged; 2. The induction coil is damaged; 3. The sensor is damaged; 4. The tachometer needle is stuck. The tachometer is installed in the instrument panel and works according to the magnetic principle. The tachometer receives the pulse signal generated when the primary current in the ignition coil is interrupted, and converts this signal into a displayable speed value. Taking the 2020 Kia K5 KaiKu Fashion Edition as an example, its front suspension is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension. It is equipped with a 1.5L turbocharged engine, with a maximum horsepower of 170PS, a maximum power of 125kW, a maximum torque of 253Nm, and is matched with a 7-speed dual-clutch transmission.
My Kia K5's tachometer isn't working, and I suspect it's likely a sensor issue, such as a faulty crankshaft position sensor, which measures engine speed and transmits it to the dashboard. Sometimes, aging wires or loose connectors can also interrupt the signal. I tried checking the fuses myself because the fuse box is near the driver's seat and easy to locate—if one is blown, I can just replace it. Last time I encountered a similar issue, it was due to wet wiring causing a short circuit on a rainy day. Driving at high speeds without a functioning tachometer is particularly dangerous, as you can't monitor the engine's condition, risking overspeeding or overheating. I recommend not taking it lightly and first stopping by a roadside repair shop for a quick check. If simple issues are ruled out, then deeper diagnostics like checking the ECU or instrument cluster module should be left to professional technicians. Regular maintenance checks can help prevent such failures.
