What's wrong with jumping up and down on the sylphy tachometer?

The disorderly jump of Xuanyi tachometer in Pacific Auto Network may lead to the failure of tachometer. It is only necessary to refresh the automobile ECU, or it may be caused by excessive carbon deposition in some parts such as automobile throttle, idle motor, air intake, intake valve, combustion chamber and fuel nozzle.

Tachometers are often used in manufacturing industries such as motors, electric fans, paper making, plastics, chemical fibers, washing machines, automobiles, airplanes and ships. The most commonly used is the hand-held centrifugal tachometer. Tachometer measurement is essential in all fields of national economy. The advantages of tachometer are as follows.

1, the pointer with large static moment is not easy to shake and has strong anti-vibration performance.

2. The software design adopts single chip microcomputer, which has high precision and strong anti-interference ability.

3, the hour meter adopts liquid crystal display, no mechanical parts, so it is more reliable and more contemporary. Engine throttle failure, idle speed control valve failure, air leakage in engine intake pipe, engine carbon deposition, charging circuit failure and other reasons, it is recommended to contact the local 4S shop for inspection and maintenance.
