Symptoms of a bad transmission speed sensor

transmission speed sensor

The transmission speed sensor measures the amount of revolutions occurring in the transmission which helps the transmission control unit determine the rotational speed of the wheels. This information allows the computer of your vehicle to help it shift gears smoothly so that the vehicle can run efficiently. This particular sensor cannot be repaired once it becomes faulty. Usually, it just becomes faulty after years of using it. There isn’t much you can do to maintain the lifespan of the speed sensor. The only thing you can do is replace it once it becomes faulty. That is why it is important to know the warning signs of a bad transmission speed sensor so that you can have it replaced as soon as possible.

The Common Symptoms of Faulty Transmission Speed Sensor

A simple symptom of a faulty speed sensor is the inability to use cruise control. You may try to set the speed for the cruise control but then the car will continue to decelerate anyway after you take your foot off the gas pedal. Another symptom is when the speedometer or odometer stops working. When the speed sensor is faulty then obviously the speedometer isn’t going to be able to detect how fast you are going. This will make it dangerous to drive because you won’t know if you are abiding by the speed limits or not. As for the odometer, this may not necessarily affect your driving but you’re still required to have a working odometer if you ever want to sell your car. Plus, it is important to have a working odometer because it helps you determine when you need oil changes and other forms of maintenance for your vehicle.

Shifting gears will also be difficult with a faulty speed sensor. Sometimes the transmission will be late when going in overdrive and other times you may not even be able to shift into higher gears at all. This means you won’t be able to drive your car because your risk of having an accident will greatly increase. But you shouldn’t even wait for the problem to get to this point. As soon as you notice a problem with your speedometer or odometer, then you’ll want to take your car to the local auto body shop right away. Even though these problems may not affect the ability to drive, they will still affect your judgment and driving decisions while you drive. So it is best to have them taken care of right away.
