Apparently, if your car’s wheel speed begins to decline, you’ll get a warning. There are two ways to tell if something is wrong with your car’s wheels: the check engine light will come on, or you will notice a number of other indicators. How long can you safely drive a car with a malfunctioning speed sensor?

If you have a defective wheel sensor, you may still be able to drive for extended distances despite the problem. However, because today’s cars are more advanced than ever before, a malfunctioning wheel sensor could potentially put your vehicle to a halt because to the numerous smart systems that work together.

How Long Can You Drive a Car With a Bad Speed Sensor?

Understanding how speed sensors work will give you an idea of how long you can drive if one or more of them fail. A car with four wheels would have four speed sensors attached to each of its wheels; hence, it would have four speed sensors. These sensors monitor the rotational speed of the wheels they are mounted on and send electrical impulses to the transmission, ABS, and ESP control units. Newer current cars have wheel sensors that can measure the speed at which each wheel rotates, making this feature much more useful.

With this information in mind, below is what happens if one or all of the wheel speed sensors fail. The ECM, ESP, or ABS system would be unable to function properly if the speed sensor was defective or fully broken. For example, if your ABS system processes incorrect signals, it may cause problems with gear shifting, driver assistance systems (like cruise control) to malfunction or other issues to arise. Because the erroneous signals it provides to the ABS or transmission can cause certain smart components of your car to malfunction, a malfunctioning speed sensor doesn’t technically prevent your automobile from running. Although driving a car with a defective wheel sensor is risky and should be avoided, it is possible to fix the problem. Speed sensors, on the other hand, are quite easy to replace. While it’s possible that only one of the sensors has failed, it’s best to replace them all at once because they’re cheap and easy to fix.

How Long Can You Drive a Car With a Bad Wheel Speed Sensor?

Speed sensors and wheel speed sensors are not the same thing. It is true that these sensors are also referred to as ABS or transmission sensors, respectively. As a result, the information presented above is relevant to this inquiry as well. You can troubleshoot to identify the precise defective wheel speed sensor if you see any of the following symptoms: Regardless, if at all possible, replace them all at once; this is both more beneficial and kind.

What Happens When a Wheel Speed Sensor Goes Bad?

A defective wheel speed sensor can have a variety of effects on different vehicles. However, your car’s performance is likely to be negatively impacted. You may encounter the following situations when your car’s speed sensors go out of service.

1. Loss of Traction

You’ll notice that your car is unbalanced on the road, your traction control has changed significantly, and going up hills is tough. The most typical indicator is a decline in emotional stability, but there may be others.

2. Check Engine Light Will Come On

The transmission may shut off certain controls and display the dashboard check engine light when it receives incorrect signals from a malfunctioning speed sensor, according to reports.

3. Transmission Problems

If your car has an automatic gearbox, a defective or failed wheel speed sensor will have a direct impact on your vehicle’s performance. Consistent automatic transmission operations, such as hard or delayed shifts, inconsistent gear changes, etc., are among the most common symptoms of a bad wheel speed sensor. Worn-out wheel speed sensors can lead to a variety of problems, the most prevalent of which are those relating to the transmission.

Can You Drive With a Bad Wheel Speed Sensor?


How long can you drive with a defective speed sensor? There’s no way to tell how long it will take you to get back on the road if your vehicle’s speed sensor fails (wheel speed sensor). However, if you notice indicators that your speed sensors are ready to fail, you should take action to avoid more expensive repairs, such as a gearbox breakdown. Speed sensors are also known as vehicle speed sensors, wheel speed sensors, ABS sensors, and transmission sensors, to name just a few variations.Since both of these titles refer to speed sensors, it’s safe to assume that they’re referring to the same thing
