The transmission control module (TCM) oversees the operation of the automatic transmission. To determine how fast the input shaft is spinning, the TCM gets the readings from the input speed sensor.
If the powertrain control module (PCM) or TCM detects a problem with the input speed sensor designated “A”, it will log a P0716 code.
The Diagnostic Trouble Code (DTC) P0716 stands for “Input/Turbine Speed Sensor “A” Circuit Range/Performance.”
The input speed sensor measures the revolution speed of the input shaft (torque converter turbine shaft). If the vehicle uses more than one input/turbine speed sensor, it will designate the device mounted near the transmission input shaft as the A sensor.
The PCM takes the reading from the input speed sensor and interprets it as transmission input/turbine speed. Then, the module uses that information to control output functions, such as torque converter operation and line pressure control.
If the input speed sensor’s reading doesn’t match the ideal input/turbine speed, the PCM or TCM will set the powertrain code P0716.
Note: Depending on the car manufacturer, the definition of code P0716 can vary. Check the appropriate repair manual or repair database to make sure you get the code’s correct definition.
The DTC P0716 code is a generic powertrain code that can apply to vehicles built in 1996 or later. While it’s a generic code, the steps needed to evaluate and fix this problem can vary from vehicle to vehicle.
If you do not have sufficient knowledge or experience to test your vehicle, it’s recommended to bring it to a certified mechanic. Otherwise, you can go ahead and run diagnostics on the issue yourself. To help you, here is a video that can give you an idea of what diagnosing and fixing your vehicle might involve:
Trying to diagnose and repair a P0716 code can become a frustrating task if you don’t have the right tools and knowledge to test the input speed sensor. In most cases, it’s a good idea to consult a professional.
For DIYers with advanced technical knowledge and hands-on experience who prefer to test and replace their vehicle’s input speed sensor/crankshaft position sensor on their own, it’s a good idea to check the appropriate repair manual or refer to an online repair database.
