Can the car still be driven if the speed sensor is broken?

If the speed sensor is broken, the car can still be driven, but it is best to drive at a relatively slow speed to the nearest auto repair shop for maintenance or replacement. After all, a faulty speed sensor will directly affect the vehicle's driving safety system, leading to a decrease in the car's stability performance. At this time, aggressive driving poses significant safety risks. Here is some relevant information about the speed sensor: Introduction: The speed sensor is a device used to detect the speed of electronically controlled vehicles. The control computer uses this input signal to regulate engine idle speed, torque converter lock-up in automatic transmissions, automatic transmission gear shifts, and the opening and closing of the engine cooling fan, as well as cruise control and other functions. Features: The speed sensor is usually installed inside the drive axle housing or transmission housing. The speed sensor signal line is typically enclosed in a shielded sheath to eliminate electromagnetic and radio frequency interference caused by high-voltage ignition wires, car phones, or other electronic devices. This ensures uninterrupted electronic communication and prevents degraded driving performance or other issues.

I think the vehicle speed sensor is broken, but the car can still be driven—just don’t take it lightly. The engine should run normally and can still start, but there are plenty of issues: the speedometer might not work, making it easy to speed unknowingly; if the ABS fails, braking distance increases, which is especially dangerous in rainy weather; the automatic transmission might shift erratically, staying in low gear and roaring, wasting fuel and making driving difficult. I’ve seen a friend insist on driving like this, only for the transmission to completely fail later, costing a fortune in repairs. It’s a major safety concern—best not to drive long distances and get it fixed by a professional shop ASAP. Don’t risk it for convenience. Remember to regularly maintain and inspect the sensor to prevent such failures.

Last time my vehicle speed sensor broke, I could still drive, but the experience was awful. The speedometer completely stopped working, so I had to rely on feeling or a speed-measuring app on my phone. The ABS failed, and I almost skidded when braking on wet roads. The automatic transmission got stuck in second gear, causing fuel consumption to skyrocket like it was guzzling gas. I barely managed to commute for a while, driving in constant fear every day, and eventually had to get it fixed. The repair wasn’t expensive—just a few hundred bucks—much cheaper than an accident. I suggest stopping or driving slowly to a repair shop if your sensor fails, unlike me who stubbornly pushed through. Regularly check the electrical system to prolong component lifespan.

From a technical perspective, if the vehicle speed sensor fails, the car can indeed start and move since the engine operates independently. However, other systems rely on it: the speedometer may display inaccurately, ABS and stability control could be disrupted, and the automatic transmission might experience delayed or faulty gear shifts. I do not recommend driving under these conditions, especially in urban traffic or on highways, due to the high risks involved. It's advisable to promptly use diagnostic tools to check for trouble codes. Replacing the sensor is usually a straightforward process, often completed in about 30 minutes. Ignoring the issue can damage core transmission components, potentially doubling repair costs. Regular vehicle inspections are a preventive measure.
