Where is the turbine shaft speed sensor located?
Located on or inside your vehicle’s transmission, the turbine speed sensor measures the RPM of the turbine shaft. Once the PCM or TCM detects an irregularity in the turbine speed input, it will trigger the illumination of the Check Engine Light.
What is a turbine input shaft speed sensor?
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.
Where is the input speed sensor located?
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.
What does the input shaft speed sensor do?
There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. 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.
What’s the difference between input and output speed sensor?
Transmission input/output sensors calculate the transmission’s actual gear ratio during usage. 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.
How does the input shaft speed sensor work?
The input speed sensor detects the primary pulley revolution speed and sends a signal to the Transmission Control Module (TCM) and Engine Control Module (ECM). – Transmission speed sensor circuit is open or shorted.
What happens when turbine speed sensor does not work?
If the output shaft speed doesn’t match the expected speed, the computer knows something is slipping inside the transmission. It can then try to boost the fluid pressure to compensate. If that doesn’t work, it sets a different trouble code. But first it needs the input from the input turbine speed sensor.
When does Toyota transmission speed sensor no signal?
– Poor transmission speed sensor circuit connection – Faulty transmission speed sensor The Error code is generally activated on detection of the following conditions: Diagnostic Trouble Code (DTC) P0717 Toyota is detected when TCM or ECM receives no signal from the sensor.
What does p0717 input turbine speed sensor circuit no signal trouble code?
If you have a P0717 Input Turbine Speed Sensor Circuit No Signal trouble code, this post will help you understand what it is and how to fix it. The computer wants to know if the transmission is working properly. So it reads the speed of the input shaft and compares it to the speed of the output shaft.
