VSS Replacement 1) Loosen and remove negative battery cable. 2) Locate the faulty speed sensor and disconnect the speed sensor connector. 4) Check the connector wiring to insure there are no breaks or exposed wire. 5) Verify O-ring is installed on new sensor. 6) Install and tighten new sensor.
Where is the transmission speed sensor located?
Locate the speed sensor. The sensor is found on the bottom of the transmission and can be identified as a small plug that is sticking straight out of the transmission with an electrical connector plugged into it.
How long does it take to replace a transmission sensor?
Three to four days. It usually takes three to four days to replace or repair the entire transmission system.
How much does it cost to replace a transmission sensor?
The average cost for transmission position sensor replacement is between $249 and $298. Labor costs are estimated between $137 and $173 while parts are priced between $112 and $126. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
What happens when your transmission speed sensor goes out?
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.
Can I drive without a speed sensor?
While it’s technically possible to operate your vehicle without a properly functioning vehicle speed sensor, it is strongly discouraged. A faulty VSS can negatively impact multiple aspects of vehicle operation—which is why it’s best to replace a bad speed sensor as soon as possible.
Is it easy to replace speed sensor?
However, some vehicles with anti-lock brakes use speed wheel and transmission output to spot any faults whereas those that have no anti-lock brakes use the transmission output alone. Fortunately, it is easy to replace a wheel speed sensor and takes you about an hour at maximum.
How much does a transmission speed sensor cost?
The DIY cost for replacing a speed sensor is the cost of the sensor. Depending on the vehicle year, make and model, a speed sensor can cost as little as $7.92 or as much as $100. For most vehicles, the cost for a speed sensor is between $25 and $45.
Which speed sensor controls the transmission?
Typically, two sensors communicate the transmission data to the vehicle’s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission’s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
Can you clean transmission speed sensor?
The sensors are magnetic, and this makes them attract dust and debris. The various components of the speed sensors can gather dirt from the road and from the dust that is generated by constant sharp braking. Speed sensors need to be cleaned on a regular basis to avoid damaging the anti-lock braking system.
How do you fix a transmission sensor?
Replacing Your Transmission Speed Sensors Having found the sensor or sensors to be faulty, remove the connector between the sensor and the vehicle’s wiring. Using the proper socket, remove the faulty sensor. Connect the new sensor to the vehicle’s wiring. Install the new sensor. Lower your car. Start the engine.
How many wheel speed sensors are on a car?
Modern vehicles have four wheel speed sensors: two front wheel speed sensors and two rear wheel speed sensors. That is, each wheel of your car has a wheel speed sensor.
How can you tell if the transmission sensor is bad?
Top Signs of a Failing Transmission Position Sensor Car fails to move out of park. When your vehicle is unable to shift out of neutral or park, this is a clear indication that there is a serious problem somewhere in the transition system. Transmission shifts into the wrong gear. Vehicle becomes locked in a single gear.
What causes the speed sensor to go bad?
Over time, the transmission speed sensor can go bad due to wiring issues or just outright failing due to it constantly being used every time you are driving your vehicle. If the sensor is magnetic, it can go bad from iron sticking to the tip of the sensor, which will cause an inaccurate reading.
What happens if you don’t replace speed sensor?
When the Sensor is Broken If the wheel speed sensor isn’t working, it won’t send any information to the ECU when there’s a problem. The ABS system won’t know to begin working and you can lose control of your vehicle and cause a crash.
How much does it cost to replace a 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.
Can a wheel speed sensor cause shifting problems?
Can A Bad Wheel Speed Sensor Cause Transmission Not Shift? The PCM will not be able to properly control the shifting of gears within the transmission if it does not receive a valid speed signal from these sensors. The transmission may shift more quickly or rough due to this.
