1. Damaged speedometer cable: The speedometer cable is responsible for transmitting the speed of the vehicle to the speedometer. If the cable is damaged, it can cause the speedometer needle to jump or become inaccurate.
2. Faulty speedometer sensor: The speedometer sensor is responsible for sending the speed signal to the speedometer. If the sensor is faulty, it can cause the speedometer needle to jump or become inaccurate.
3. Electrical issue: There may be an electrical issue that is causing the speedometer needle to jump. This could be due to a loose wire or a faulty electrical component.
4. Faulty speedometer: In some cases, the speedometer itself may be faulty and need to be replaced.
To diagnose the cause of this issue, it is recommended that you take the vehicle to a qualified mechanic for inspection and repair.
