What happens when a wheel speed sensor goes bad?

loss of stability and traction control: if it detects a bad wheel speed sensor, the abs computer will usually disable the stability and traction control systems, as well. on some vehicles, a bad wheel speed sensor may affect other functions as well, such as hill-start assist and roll stability.

How much does it cost to replace a vehicle speed sensor?

It also informs the car’s computer how much power needs to be applied to stop the car safely. To replace the speed sensor, you are going to pay, on average, between $330 and $380. The labor should only cost you between $80 and $100, while parts will run you about $265.

What causes a transmission speed sensor to fail?

Also, the plastic portion of the sensor can become brittle after prolonged exposure to the elements. The magnetic portion of the sensor may also become worn and damaged over time. The speed sensor measures the rotation of a toothed wheel on a shaft inside the transmission to determine how fast your car is going.

How do I know if my wheel speed sensor is bad?

Noted below are a few of the warning signs of a bad or failing wheel speed sensor for your review….Symptoms of a Bad or Failing Wheel Speed Sensor

  1. ABS Light is illuminated on the dashboard.
  2. ABS does not work properly.
  3. Traction Control Light is active.

How can you tell if the speed sensor is bad?

When there’s no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won’t control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.

How do you know if your transmission speed sensor is bad?

If your transmission becomes bucking-broncoesque, pull over. You’re likely to cause serious damage to a number of parts if you continue. A fluctuating speedometer may be a sign of a faulty transmission sensor. If you have a truck or SUV with enough ground clearance, you won’t need to jack up your car.

How much does it cost to replace wheel speed sensor?

Transmission speed sensors tend to cost around the same. Labor varies depending on the engine type, as some sensors are more accessible than others. If your mechanic needs to drop the transmission to replace a transmission sensor, you’re looking at bill around $800-1,000. Wheel speed sensors are generally pretty accessible and easy to replace.

Where is the speed sensor on a car?

The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.
