How does an input turbine speed sensor work?
How does an input turbine speed sensor work?
Manufacturers simply use variations in terminology to describe them. 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 causes erratic input / output speed sensor readings?
Excessive metallic debris (accumulated to the electromagnetic sensor) can cause erratic input/output speed sensor readings. Sensor to reluctor clearance is extremely important, so make sure that mounting surfaces/threaded holes are clear of any debris or obstructions.
What to do if turbine shaft speed sensor is not working?
The TCM also monitors the turbine speed sensor itself for problems, which it would expect to find in a certain range and change speeds at a certain rate. If the TCM detects problems with the TSS or TSS circuit, it will set a diagnostic trouble code (DTC) in memory and command the ECM to illuminate the check engine light.
What is the fault code for turbine shaft?
Thanks, Input and output shaft sensors or signal failure problems should throw fault codes P0717 & P0722. I have the workshop manual for this car with all the wiring diagrams, and ohms values to check etc, so i’ll give your recommendations a try….
What is the name of the transmission speed sensor?
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’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
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.
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).

How can I repair the transmission speed sensor?
Consult the repair manual for your car. Place bucket or oil drain pan underneath the sensor, there will be some oil that drains out. Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling.
What can be done to an input speed sensor?
Depending on the diagnosis, common repairs for this code include: Repair of damaged wiring for input speed sensor Repair or replacement of faulty wires, connectors, battery cables, battery cable ends, and cleaning of battery terminals The rebuilding of damaged transmission (from findings and contamination in transmission fluid)
What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on. The transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use.
What is a speed sensor in a transmission?
The transmission speed sensor is a magnetic sensor that provides this information, allowing the transmission to shift smoothly. The sensor counts the internal number of revolutions of the transmission and transmits that information to the transmission control unit, where the data is used to determine the rotational speed.
Where is the turbine speed sensor located?
The turbine speed sensor is located on the drivers side of the transmission just above the shift lever and sensor. The turbine sensor is mounted in the side of the transmission.
What is a turbine input speed sensor?
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).
