What is the reason for the sudden stop of the Cruze tachometer?
2 Answers
Cruze tachometer not working reasons are as follows: 1. The flexible shaft connection inside the tachometer is disconnected: The tachometer pointer does not move due to the disconnection of the flexible shaft connection inside the tachometer. In this case, you can go to a professional 4S store for repair. 2. The tachometer pointer is detached or stuck: The tachometer pointer does not move because the tachometer pointer is detached or stuck. Do not drive easily in this situation, as it can easily lead to accidents. 3. There is foreign matter inside the instrument panel: Foreign matter inside the instrument panel prevents the pointer from rotating, and the foreign matter should be cleaned out in time. 4. Problems with the circuit inside the tachometer: The circuit inside the tachometer has problems, aging or burning out.
My old Cruze also had the issue of the tachometer not working—it might be due to a faulty crankshaft position sensor, which controls the RPM data. Sometimes, carbon buildup or water ingress can cause it to fail. Another possibility is loose or corroded wiring connections on the dashboard, leading to signal interruptions. Check the fuses, usually located in the engine compartment fuse box, labeled 'TACH' or 'RPM.' If the ECM trouble light comes on, it indicates an issue with the engine control module, and you’ll need to scan the codes. Short circuits in the wiring are also common, especially where wires rub in the cabin corners. I’d suggest first checking the fuses and connections before considering replacing the sensor or seeking professional repair. Don’t delay too long, as it could affect driving safety.
