Can ABS Sensor Cause Transmission Problems

ABS Sensors help to regulate the speed and brakes of a vehicle. They are also called speed wheel sensors and are attached to the four wheels of a car.

When any of the ABS sensors are bad, the signals and information it sends through the channel become disorganized and incorrect, and when that happens, certain parts of the vehicle will shut down, especially when the vehicle is digitalized.

Therefore, can ABS sensor cause transmission problems?

ABS sensors can certainly cause transmission problems in a car when wrong information is being passed into the ABS computer. Your car system will try to protect itself from misinformation and this leads to transmission problems such as faulty gears, shifting incorrectly, and malfunctioning brakes.

Can ABS Sensor Cause Transmission Problems?

Yes, the ABS sensor causes transmission problems, because when any of the ABS sensors are bad, information transmitted to the ABS is distorted, leading to wrong information, and when information is wrong, your vehicle translates it and does the wrong thing.

For example, when your speed isn’t accurate, as it hasn’t been accurately calculated by the bad ABS sensor, the system won’t know when it is time to change gear and change it at the wrong time, or doesn’t change it at all when it should, and this causes transmission problems.

If your vehicle is a smart one with better-computerized systems, it detects that something is wrong and shuts down several parts of the vehicle, like the gears, for example, and this invariably causes transmission issues.

The best way to avoid transmission issues caused by the ABS sensor is to pay attention to the ABS light. Once it is switched on on your dashboard, inspect each of your abs sensors and if anyone has gone bad, replace it.

It is best to replace all four at once if anyone has gotten bad. They are not expensive parts of a vehicle.

What to do if ABS Sensor Causes Transmission Problems

When an ABS sensor causes transmission problems, the first indication would be the ABS light on your dashboard. This means there’s something wrong with one or more of your abs sensors.

The next thing you want to do is to check if any of your ABS sensors are bad. Once you discover one or more of your ABS sensors are bad, you have to change them to maintain the integrity of the speed and balance of your vehicle.

Other Sensors That Can Cause Transmission Problems

There are several sensors in your vehicle that ensure the proper functioning and safety of your car. Some of these sensors, when they are bad can cause transmission problems.

Some of them include:

  • Turbine Speed Shaft Sensor: This sensor calculates the shaft speed created by the automatic transmission. If it fails to calculate the actual shaft speed, transmission problems will occur.
  • Coolant Temperature Sensor: As the name implies, it measures the coolant temperature of the engine, and if it fails to measure accurately the temperature of the vehicle, transmission problems occur.
  • Intake Air Temperature Sensor: This sensor is responsible for calculating the temperature of air that gets into the engine. If the air entering the engine is hotter than usual, or not to the appropriate temperature to cause the engine to function appropriately, transmission problems occur.
  • Manifold Absolute Pressure Sensor: This sensor is responsible for measuring pressure in the intake manifold of your car, that is, the load that your engine is taking all at once. Too much pressure can certainly cause transmission issues.
  • Brake Switch: This one controls the function and position of the brake pad, and we need no further explanation to know that improper positioning of the brake pads can also cause transmission issues.

How do I Know if my ABS sensor is Bad?

The first sign of a bad ABS sensor is the ABS light. It will come on, telling you that something is wrong, and you need to check your ABS sensors.

The next thing is the Check Engine lights. It will pop up as well as time goes on. Then you start having little transmission and brake problems, and finally, if you’re using a very computerized automobile, your vehicle will protect you from dangerous driving by not starting at all.

Importance of ABS Sensor

ABS sensors are important parts of a vehicle because of the several functions they perform to ensure that your driving is safe, and your car is secure.

Here are several important functions of ABS Sensors:

1. Information About the Speed of the Vehicle

Imagine what would happen if you don’t know what speed you are driving at when you are driving.

The luxury of the speedometer showing you the speed of your vehicle that you enjoy isn’t just a singular, stand-alone function.

Without ABS sensors, you will not know the speed at which each of your wheels is going. This is one major function of ABS sensors.

It communicates to the ABS the speed of the wheels, and this, in turn, communicates to the gear of an automatic vehicle, when to switch.

Without this information, or with the wrong information, the ABS computer will not accurately control the gears and the brakes, which then leads to different problems in your vehicle.

2. Regulates Vehicle Stability

As a result of the information the ABS sensors get from each wheel it is attached to, they can regulate the stability of the vehicle, as correct and accurate information is passed into the system to run the vehicle smoothly.

For example, whenever the ABS sensor reads a higher speed on one wheel than on another wheel, it tries to balance the speed with the vehicle stability system to make sure the speed is balanced and regulated for safe driving.

3. Reduces the Braking Distance of Your Vehicle

There are times when you need your brakes to function faster, and some other times, when you just need the braking distance of your car to reduce.

The ABS Sensors, with the information it gets from each wheel, can reduce the braking distance of the vehicle when it is important.

4. Safety

With an ABS sensor, safety is guaranteed a lot more. This is because the ABS sensor ensures that the wheels and brakes don’t lock when you stop the vehicle. W

hen your wheels lock anytime you slow down or stop, you will put yourself in harm’s way. The ABS sensor prevents that.

5. Speed Limit

With the ABS sensor, you know what speed you are driving at and when to reduce it. Also, your automatic vehicle knows when to change gears. This helps you to maintain the speed limit required of you.


Driving with a faulty ABS Sensor is dangerous, and can lead to serious problems. Once you discover that there is something wrong with your ABS sensor, you know it is time to check and replace them. It is always advisable to replace all your sensors at the same time since they are very affordable.
