What does an input sensor do?
Transmission input/output sensors calculate the transmission’s actual gear ratio during usage. 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.
Where is the input speed sensor located on a transmission?
Furthermore, where is the speed sensor located on a 4l60e transmission? The transmission connector is located on the passenger side of the 4L60E transmission housing and on the driver side of the 4L80E transmission housing. The vehicle speed sensor is located in the tail shaft housing on the passenger side.
Which is the output shaft speed ( OSS ) sensor?
The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor.
How does the input / turbine speed sensor work?
This sensor can measure how many RPM (revolutions per minute) your input shaft is turning. Once the PCM detects an irregularity in RPM input, it will trigger the illumination of the Check Engine Light.
How is a speed sensor used in a computer?
A speed sensor driven by this cable generates a pulsed electrical signal (Figure 8.6 b) that is processed by the computer to obtain a digital measurement of speed. A speed sensor can be implemented magnetically or optically.
What is the function of input speed sensor?
The function of the input shaft speed sensor is to keep track of the transmission’s input shaft speed. The clutch connects the input shaft to the engine which allows it to turn at the same speed.
Where is my input speed sensor located?
Input speed sensor is located inside the transmission . The sensor is located next to the sprocket for the input shaft. The sensor is held in place with 2 6mm bolts, one for the sensor, one for the wiring harness. Input Speed Sensor P0717 Replacement
What does the transmission input speed sensor do?
Transmission Input Speed Sensor. The input speed sensor measures the RPM of the input shaft of the transmission. With the engine running and the vehicle in gear (forward or reverse), if the car or truck is not moving, the input shaft of the transmission is also not moving.
What does a bad speed sensor do?
A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system , speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
