What is the reason for the speedometer of Besturn B70 not moving?
4 Answers
Here are the reasons and troubleshooting methods for the speedometer of Besturn B70 not moving: 1. Reasons: (1) The vehicle speed sensor or its driving mechanism is faulty. (2) The speedometer (speed indicator) is faulty. 2. Troubleshooting methods: There are two situations when the speedometer does not move. One is when it stays at 0, which usually indicates a broken or short-circuited display. The other situation is when it stays at the maximum point, commonly referred to as "pegging the needle," and it can be reset. If it stays at 0 and the mileage number also does not move, it is highly likely that there is an issue with the speed sensor, or there might be a problem with the wiring between the instrument and the sensor. In such cases, it is recommended to seek repair at a service center.
I've been driving the Besturn B70 for several years, and it's quite common to encounter a speedometer that stops working. Usually, it's due to a problem with the speed sensor. The sensor is installed near the wheels and can easily get clogged or damaged by dust or water, preventing the signal from reaching the dashboard. Another issue could be the dashboard itself, such as poor internal wiring connections that loosen over time due to aging—this requires opening it up to inspect. Short circuits or broken wires are also common, like when the wires connecting the sensor and the dashboard get crushed or chewed by rodents. In such cases, you should check if the fuse is blown—the fuse box is located in the engine compartment, and replacing it might solve the problem. Additionally, a malfunction in control modules like the ECU can cause this issue, or the speed might falsely read zero if the connector loosens due to vehicle vibrations. If you've changed tire sizes or have unstable tire pressure, the sensor calibration can get messed up, causing the speedometer to freeze. It's best to visit a repair shop quickly to diagnose the issue with a scanner—don't delay as it affects driving safety. Replacing a small sensor usually costs just a few dozen bucks. When washing your car, take care to protect the sensor, and during regular maintenance, remind them to check the wiring—it can save you a lot of hassle.
I own a Bestune B70, and last year the odometer suddenly stopped working. At first, I thought it was a minor issue. Initially, I suspected low battery voltage affecting the power supply, but after checking, the voltage was normal. Then, I disassembled the dashboard and found that too much dust had clogged the signal interface. After cleaning it, the odometer still didn't work, so I realized the speed sensor might be faulty. The sensor is located near the rear wheel, and upon inspection, it turned out that mud and water had corroded the connector. After replacing the sensor, everything worked fine again, but the whole process took a day and cost over a hundred yuan. I've also encountered issues with aging wiring—older cars are prone to insulation breakdown, which can cause short circuits and stop the odometer. Software bugs in the control unit can also be a culprit; sometimes, restarting the car doesn't help. I recommend checking the fuse first, as it's often the cause of signal interruption due to blowing. While driving, you can rely on a navigation app as a temporary substitute for the odometer, but don't make it a long-term solution—it's risky.
My Bestune B70's speedometer is stuck, and I'm quite anxious, not knowing what the issue might be. It could be that the speed sensor is blocked by something, or the wiring isn't connecting to the dashboard. First, I'll check the fuse myself—it's simple and quick. If that doesn't solve it, I'll try to see if the sensor is loose by reaching near the wheel to feel it. A faulty control module can also cause the speedometer to malfunction, so I'll try restarting the car. If I often drive on bumpy roads, the connections might loosen. It's best to take it to a professional shop for repair and avoid tampering with it randomly.
