What is the reason for the tachometer not returning to zero?

The reasons for the tachometer not returning to zero are: 1. The speedometer in the vehicle's instrument cluster malfunctions, causing the tachometer needle to stop moving; 2. The vehicle's mileage sensor fails. Check if the flexible shaft connection is disconnected, then observe whether the mileage starts to increase. If only the tachometer stops working, it needs to be replaced with a new one; 3. There is a foreign object stuck inside the instrument, preventing movement. Open the instrument to remove the foreign object. The tachometer is usually located within the instrument panel, placed symmetrically with the speedometer and odometer. It operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted, and converting these signals into displayable RPM values. The faster the engine speed, the more pulses the ignition coil generates, resulting in a higher RPM value displayed on the gauge.
