What is an output shaft sensor?
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.
What does a turbine shaft speed sensor do?
A turbine speed sensor, also termed an input speed sensor, is used for measuring the performance of the turbine by evaluating transmission performance and other components of the turbine. It also detects the rotation speed of the turbine, which shows the input revolution of the transaxle.
How does an output shaft speed sensor work?
The output shaft speed sensor detects the speed of the drive wheels and sends this information back to the engine control unit. Together these two shafts allow the wheels to rotate at a speed that is manageable while the engine continues to run at a speed that makes it perform efficiently.
Are sensors analog or digital?
So as we see, sensors are analog devices, if we need to connect some sensor to a microcontroller in some project, we need an analog to digital converter (ADC) to convert it from an analog signal to a digital signal.
How much is a speed 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. Follow these procedures for replacing a faulty vehicle speed sensor (VSS).
What does the input/turbine speed sensor do?
The input/turbine speed sensor is usually an electromagnetic, 3-wire sensor used to monitor transmission input speed (recognized by the PCM as revolutions per minute or RPMs). The sensor is positioned near the rear of the torque converter (at the transmission input shaft) and is either mounted with a bolt/stud or threaded directly into the transmission case.
Where is the output shaft speed sensor located?
The output shaft speed sensor is located on the left rear of the transmission, the circuit runs from the sensor to the PCM.
What does the turbine input sensor do?
A turbine speed sensor, also termed an input speed sensor, is used for measuring the performance of the turbine by evaluating transmission performance and other components of the turbine. It also detects the rotation speed of the turbine, which shows the input revolution of the transaxle.
What is the main shaft speed sensor?
The Main Shaft Speed Sensor measures the rotational speed of the transmission gearing exiting the main case , taken from the auxiliary upper countershaft gear. The Output Shaft Speed Sensor measures the rotational speed of the output shaft taken from the Output Shaft Tone Wheel.
