how to fix a stuck speedometer needle
The common reasons for the immobility of the automobile speedometer are as follows: 1. The speedometer of the vehicle instrument assembly type may be faulty, resulting in the non rotation of the pointer in the meter; 2. It may be that this table causes the wheel speed sensor of the vehicle to fail to rotate. Specifically, you need to go to the repair shop for inspection; 3. First check whether the flexible shaft is disconnected, and then check whether the mileage number increases when starting. If the tachometer doesn't work, there is no need to repair it and replace it with a new one.
If not only the speedometer needle stuck:Different cars have different instruments. However, the conventional instruments of ordinary cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging meter, etc. Various indicators or warning lights are made under the mask of modern automobile instrument panel, such as coolant level warning light, fuel level indicator light, washer level indicator light, charging indicator light, high and low light dimming indicator light, transmission gear position indicator light, anti lock braking system (ABS) indicator light, driving force control indicator light, airbag (SRS) warning light, etc. The pointer of the car meter doesn't move at all. First check whether the connection of the flexible shaft is disconnected, and then check whether the mileage increases when starting. When the reading of the automobile electrical instrument is abnormal, it is inferred through analysis that the sensor or the wire between the sensor and the indicating instrument may have a grounding fault, and the disconnection method is often used for inspection.
The battery is charged, but the vehicle cannot start. It is likely that the fuse responsible for starting the motor has blown out. It should be noted that when the vehicle cannot be started, remember not to ignite continuously. Continuous ignition will lead to the embarrassing situation of continuous battery discharge and complete power failure. When the vehicle is driving downhill, the tachometer displays normally, but the speedometer displays zero. Meanwhile, the ABS warning light is on, indicating that the fuse corresponding to ABS is blown. Some irregular businesses will unplug the ABS fuse when transporting vehicles, so as not to increase the mileage, but the hidden danger brought by this is very large.
