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

A faulty tire sensor won’t stop the vehicle, so you can still drive great distances. However, it is not safe to drive your car with a bad speed sensor. The speed sensor in the vehicle is a speedometer that tells the computer how quickly the car is traveling. The system then adjusts the tachometer, Rotor speed, and transfer gauges.

When the vehicle’s wheel speed slows, you will receive the indications. It either causes the check engine light to come on, or you find other symptoms that the tires are damaged.

This article explains how all these sensors function, what they perform, and how they might impact you if something goes wrong. Keep reading to resolve them before they become serious issues.

“How Long Can I Drive a Car with a Faulty Speed Sensor?”

It is essential to know how speed sensors function. Since this will provide a clear overview of how long you may continue driving if one or more of them fail. A car has speed sensors for each tire.

These sensors monitor the speed of each tire to which they are mounted. Also, they provide the data to the transmitting monitoring system through electrical impulses.

Additionally, the tire sensors of modern automobiles can monitor the rotational motion of each tire to which they are linked.

Now that you understand the roles of tire speed sensors. Let’s review what occurs when one or more of the sensors malfunctions. When a sensor is damaged or defective, it sends incorrect signals to the associated system. Or sometimes no signal at all.

When the ABS receives these inaccurate signals, you might encounter irregularities such as trouble shifting gears and malfunctioning automated driving technologies. A faulty speed sensor won’t stop the automobile from operating, but it might cause the ABS or gearbox to malfunction.

Therefore, driving a vehicle with a defective wheel sensor is unsafe and not recommended. Moreover, replacing speed sensors is affordable. Even if only one sensor may be defective, it is best to replace them all at once since it’s easy to repair.

What Happens If a Wheel Speed Sensor Fails?

The impact of a defective tire speed sensor may vary across vehicles. Although, the vehicle’s speed would be reduced.

Traction Loss

You would realize that the vehicle is not balanced on the roadway. Traction control would be completely changed, and you would have difficulty driving on hills. You might well observe other similar symptoms, but a loss of stability is the most common.

The Check Engine Light Will Illuminate

When the transmissions detect incorrect information from a faulty speed sensor, it may disable some functions and flash the check engine light.

Transmission Issues

A defective or malfunctioning tire speed sensor will directly impact the vehicle transmissions if it has an automatic gearbox. Irregular automatic gearbox actions are among the most prevalent indications of a faulty wheel speed sensor, such as quick or late shifting and inaccurate gear changes.

Lack of control, balance, friction and transmission-related problems are the most common results of faulty tire speed sensors.

Can You Drive with a Faulty Speed Sensor?

Driving a car with a defective wheel speed sensor is often dangerous. The vehicle’s computer system won’t be able to estimate the car’s speed. So, it may hit the brakes more quickly than required or boost engine power. This might lead to an accident if you’re driving too quickly for the circumstances.

If you have a faulty speed sensor and require servicing, you should call a professional as soon as possible. You may wonder why it is so essential. There are several reasons, but safety is the most apparent. Last but not least, you can drive with a faulty speed sensor. But, first fix the issue and then drive on the roadway.

How Can Speed Sensor Malfunctions Occur?

A car’s speed sensor might malfunction for a number of reasons. The vehicle may have been harmed in a collision where the tire was totally removed, which would prohibit it from receiving resources and information. In other situations, rust or dirt may develop on the cables inside the wheel that link the car’s computer to the rest of the car.

Most sensors don’t need to be changed but have it looked out if something isn’t functioning properly. You can also hire professionals. They will fix it with less labor cost. So, don’t wait, have it checked and fix it.

Can You Change Your Own Speed Sensors?

To fix the speed sensor on the vehicle, you must first detach the wheel. And then the internal liners to have entry to the cables. Then after, you must be able to remove and replace the old sensor.

If you feel uncomfortable with any of these steps, you must consider professional assistance. You might make the situation worse. Additionally, you should determine which ABS sensors are defective before replacing them. So, hiring a professional would be a good alternative.

Frequently Asked Questions

How Can I Prevent Difficulties with My Car’s Speed Sensor?

The simplest method to prevent difficulties with the car’s speed sensor is to ensure that all of its components are in proper working condition. You should also have monthly checkups so that you can detect any issue as quickly as possible. Otherwise, it might lead to serious complications.

How Much Does the Replacement of a Speed Sensor Cost?

If you suspect that the car’s speed sensor is defective, a specialist may be able to repair it for about $300. But in some cases, it might cost more. However, that is not excessively costly when you consider that difficulties with this component might lead to losing vehicle control and cause an accident.

Can I Drive with A Defective Speed Sensor?

Driving a motor vehicle with a defective wheel speed sensor is dangerous. If you are driving on a wet road, you generally won’t even notice much change in the driving experience. Even if the ABS light illuminates if the tire speed sensor is broken or worn out. So, yes, you can drive but should not.

Can A Faulty Speed Sensor Cause Transmission Damage?

The PCM may cause jerky gear changes and affect the transmission’s shifting time. In addition, a defective sensor may cause serious damage to the motor gear pairs and other interior parts. Such as hydraulic hoses, valve chambers, and more if the vehicle has an automated transmission system.

What Happens When a Vehicle’s Speed Sensor Malfunctions?

A faulty speed sensor will directly affect the functioning of an automatic gearbox. Therefore, a malfunctioning automatic gearbox is among the most frequent indications of a faulty speed sensor. If the VSS is defective, gearbox indications may include slow switches, difficult shift patterns, and restricted gear functioning.

Final Words

To prevent issues with the ABS sensors, you should maintain the vehicle. This requires routinely examining the tires and brakes for corrosion before a problem emerges.

Additionally, be sure to maintain records of all car maintenance. So that if anything does go wrong, you can have it serviced immediately. Although, if you see the warning signals, the speed sensors are likely to fail. Then it would be wise to take preventative action to avoid costly repairs such as gearbox failure.

Speed sensors are also known as car speed sensors, tire speed sensors, Brake sensors, and gearbox sensor systems. Therefore, whenever you hear any of these terms, it refers to the same thing, the sensors of speed.
