How does an input turbine speed sensor work?
With this, it’s important to consult with the manufacturer’s service manual for the exact location of the input/turbine speed sensors designated A. An input/turbine speed sensor is usually electromagnetic; it’s a 3-wire sensor that works by monitoring the transmission input speed (recognized by the PCM as revolutions per minute or RPMs).
Where is the transmission input speed sensor located?
Users have reported p0715 for the following makes: Mercedes Benz (especially on a Mercedes Benz ML320), Ford, Nissan, Mazda, and Mitsubishi. An input speed sensor reads a reluctor ring. Located on or inside your vehicle’s transmission, the sensor is tasked to monitor your vehicle’s transmission input speed.
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.
When does the input speed sensor set the OBDII code?
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 ). The ECM sets the OBDII code when the Input Speed Sensor is out of factory specifications. Need more information on how to fix the P0715 code? Need more help? What is OBDII?
Where is the input turbine speed sensor located?
Consult the manufacturer’s service manual for the location of the input/turbine sensor designated A. 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).
How does the input speed sensor work on a car?
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. A vehicle may go into “fail-safe” mode as a result of this 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.
Why is my turbine speed sensor no signal?
If it doesn’t get that signal, the computer sets a P0717 Input Turbine Speed Sensor Circuit No Signal. Either the sensor is dead or there’s a circuit issue (bad wiring, etc). Alldatadiy.com and Eautorepair.net are professional-grade shop manuals—period. They include wiring diagrams and technical service bulletins.
Which is the first sensor on the transmission shaft?
The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
What happens when the transmission speed sensor does not work?
Cruise Control Does Not Work Since the transmission speed sensors monitor the input and output shaft speed, it also plays a part in monitoring the cruise control. When the sensors fail to deliver accurate data to the onboard computer on your car, truck, or SUV, the powertrain control module (PCM) will send an error code to the vehicle’s ECU.
What happens when the output shaft speed sensor falls out?
The other sensor is the output shaft speed (OSS) sensor. If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.
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.
The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft.
How is the transmission input and turbine speed measured?
The speed of transmission input/turbine speed is then compared with engine RPM speed, transmission output speed, engine load percentage, and vehicle speed to determine the right input speed RPM.
