Why is the Cruze tachometer not working?

The reasons why the Cruze tachometer is not working are: 1. The flexible shaft connection inside the tachometer is disconnected; 2. The tachometer needle has fallen off or is stuck; 3. There is foreign matter inside the instrument panel; 4. There is a problem with the wiring inside the tachometer, such as aging or burning out. The solution is to remove the negative terminal of the battery, disconnect the power for five seconds, and then reconnect it. The Cruze is a compact car launched by Chevrolet, with body dimensions of 4666mm in length, 1807mm in width, and 1460mm in height, and a wheelbase of 2700mm. In terms of appearance, the side profile of the Cruze is made very three-dimensional through the use of lines, presenting a sense of sporty forward motion.
While driving, I noticed the Cruze's tachometer wasn't moving at all. After checking, there could be several reasons for this. The most common one is a faulty or dirty crankshaft position sensor, which is responsible for monitoring engine speed and sending signals to the dashboard. A blown fuse is also a common issue—try replacing the corresponding one in the fuse box near the driver's seat. If the wiring is aged or the connectors are loose, it can also interrupt signal transmission. Restarting the engine might temporarily fix it, but it’s unstable. Don’t ignore it—without the tachometer, you can’t monitor whether the engine is overloaded, and driving too fast could damage the car. I immediately drove to a nearby auto repair shop for inspection. The mechanic used an OBD scanner to check for error codes, and it turned out to be a sensor failure. It cost 300 yuan to replace it with a new one. Now, during regular maintenance, I always remind the mechanic to clean the sensor to prevent such issues. Paying attention to dashboard abnormalities while driving daily can save a lot of trouble.
