ACDelco GM Original Equipment 2131701 Vehicle Speed …

An ACDelco GM Original Equipment Vehicle Speed Sensor reports the vehicle speed to the instrument panel and engine control module, and is a GMrecommended replacement for your vehicle’s original component. This signal is used by multiple control modules to adjust or perform functions, such as cruise control, steering assist, and climate control.


Vehicle Speed Sensors: Types of VSS

201268 · A vehicle speed sensor generates a magnetic pulse in the form of a wave, proportional to the speed of the vehicle. The power control module (also known as the electrical control module) uses the VSS frequency signal to manipulate multiple electrical subsystems in a vehicle, such as fuel injection, ignition, cruise control operation, torque, and ...


Speed Sensor an overview | ScienceDirect Topics

Speed sensor and excitor (Fig. ) The speed sensor uses the variable reluctance magnetic sensing principle, whereby a cylindrical permanent magnetic core with a coil wire wound around it, mounted on the stationary hub carrier, axle casing or back plate, produces a magnetic field (flux) which overlaps the rotating excitor excitor may be of the tooth ring or ribslot ring type ...


Easy Ways to Test a Vehicle Speed Sensor with a Multimeter

20211013 · A vehicle speed sensor, or VSS, is a sensor that is used to determine how fast your vehicle is traveling. If your vehicle’s speedometer stops working or isn’t telling you the correct speed …


How To Test Transmission Speed Sensor | The Drive

2020515 · Connect the new sensor to the vehicle’s wiring. Install the new sensor. Lower your car. Start the engine. Take a test drive. Check to make sure the transmission shifts properly. Check …


Bad Speed Sensor Symptoms and How to Fix a Broken …

2021724 · The VSS or vehicle speed sensor, also called transmission speed sensor, is the tiny device mounted on your car transmission. As I said before, its main function is to measure the speed of your car through the twisting toothed wheel that you will find in …


How to Test for a Bad Vehicle Speed Sensor | …

20101116 · Here are some ways to test the vehicle speed sensor to determine if it is faulty. Step 1: Check Sensor Reluctance. There are two ways that you can determine whether a variable reluctance sensor is bad. The first way is by checking the Ohms that the sensor …


Testing 2 and 3 Wire Speed Sensors Speedway Motors

2016913 · The tools needed for testing either a 2 or 3 wire speed sensor are essentially a multimeter with the clamp leads, and a drill. The 3 wire speed sensor is externally powered, so you will need a power source of some form. First off is testing the 2 wire speed sensor. These sensors are self powered, meaning the revolutions inside the case generate ...

VSS Vehicle Speed Sensor Testing FreeAutoMechanic

2021930 · The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile. By comparing the input and stored value, the PCM calculates vehicle speed.
