The Vehicle Speed Sensor (VSS) is located on the right rear of the transmission near the tail shaft. When there are symptoms of a bad transmission speed sensor, the powertrain control module cannot control the shifting of gears within the transmission properly.Apr 28, 2021
As the name indicates, input shaft speed (ISS) sensor is used for monitoring the speed of the input shafts of the transmission, whereas the output shaft speed (OSS) sensor is used to monitor the speed of the transmissions’ output shafts.
The Speedometer Vehicle Speed Sensor (VSS) is located in the transmission housing on the passenger side output flange. Automatic Transmission The Vehicle Speed Sensor (VSS) is located on the right side of the transmission near the output shaft.
Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.
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.
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.
In general, it is unsafe to drive a vehicle with a broken wheel speed sensor. The car’s computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.
The transmission of your vehicle can only shift smoothly with the help of a healthy speed sensor. This sensor counts the number of internal revolutions in the transmission. … Unfortunately, it is impossible to repair the transmission speed sensor as it simply fails.
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.
Sensor is located on the driver’s side of the transmission immediately behind the bell-shaped portion of the housing. It’s held in by one bolt and has a wire running to it.
The rear wheel speed sensor for a 2006 Chevy Silverado is going to be located on the wheel housing for the tire. You’re going to need to take off the outer section of the housing in order to access it. These sensors will cost between $20 and $40 each depending if You buy a generic one or an OEM one.

Your vehicle may rumble or idle irregularly when you start it, or it may burn more fuel than normal. Also, your vehicle may lose power suddenly due to wrong signals sent from the speed sensor to the fuel system.
This sensor controls ignition timing of the engine and when it fails the computer does not know when to ignite the cylinder causing the engine to stall and not start correctly.
bad speed sensor alone will not cause trans to go into limp mode.
The output speed sensor measures how fast a vehicle moves and sends that information to other vehicle systems. The transmission control unit uses the speed to determine when to change gears, adjust the torque converter and display the vehicle’s speed in the speedometer.
Now you can have the best of both worlds with a system called speed sensing steering. Speed sense steering system does exactly what its name implies. … The speed sensing steering enables power steering to continue to function at high speeds but allows for you to have more control when driving at highway speeds.
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.
The average price for the wheel speed sensor replacement cost comes to between $225 and $265, while the cost of the labor is between $69 and $87. Based on this total price, drives can expect this procedure to take between 45 minutes and 1 hour at most dealerships.
There are two of them, you may have changed the wrong one. INPUT speed sensor is closer to the motor than the OUTPUT speed sensor, which is closer to the driver side end of the trans case. You need the output one. You don’t need to reset anything but you can disconnect battery for say an hour if you want to do it.
Resetting Your ABS Dashboard Warning Light
Step One: Disconnect the positive cable from your car battery. … This will result in a reset of the car’s central computer. Plug the cable back in to restore power. If there’s no remaining problem with the system, this should reset the light.
On most vehicles, this is not an issue, but on some — notably pickup trucks — this can lead to lack of stability under heavy braking as the rear brakes lock up early. If unplugging the sensor makes your problem go away, don’t be fooled. You’ve simply disabled the entire ABS, masking the symptoms.
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.
Problem Description
The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the vehicle speed sensor is faulty, however, at times, the driven gear inside the transmission is at fault.
Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can’t adjust these symptoms on the fly can cause the engine to not start. … Faulty sensors can keep your engine from starting, but this is often engineered in as a safety measure.
