Why is the tachometer of the Verna not working?
2 Answers
The tachometer of the Verna is not working because there is a foreign object stuck inside it. Tachometers are commonly used in industries such as motors, fans, papermaking, plastics, chemical fibers, washing machines, automobiles, airplanes, and ships. The most commonly used type is the handheld centrifugal tachometer. Tachometer measurements are essential in various sectors of the national economy. The advantages of tachometers are as follows: 1. High static torque, the pointer is not prone to shaking, and it has strong anti-vibration performance; 2. It uses a single-chip microprocessor with software design, ensuring high precision and strong anti-interference capability; 3. The hour meter uses LCD display without mechanical parts, making it more reliable and contemporary.
I also encountered the tachometer malfunction when driving my Verna before, which seems quite common. The cause could be a faulty sensor, such as a loose or dust-covered crankshaft position sensor, leading to incorrect readings. Another possibility is aging wiring or poor contact inside the instrument panel. Once, I opened the instrument cover myself and found a loose wire connector, which was fixed by tightening it. Fuse issues are also frequent, so check the engine-related fuses in the fuse box to see if they're blown. Additionally, high speed or strong vibrations can worsen the problem, so it's best to visit a repair shop as soon as possible for a thorough fix. Don't compromise driving safety, as the lack of a tachometer can lead to incorrect gear shifting, affecting fuel efficiency and engine health.
