P0716 Input Turbine Speed Sensor Circuit Range Performance
If you have a P0716 Input Turbine Speed Sensor Circuit Range Performance trouble code, this post will help you understand what it is and how to fix it.
Here, let me decipher it for you. 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. It knows which gear you’re in because it commanded the transmission to shift into that gear. The turbine speed refers to the torque converter. That’s the device that transfers power from the engine to the transmission. Think of two fans facing each other. Turn on one fan and the blades on the other fan will spin. The fan that ISN’T turned on is the turbine. So, with the input shaft or turbine speed, the gear selection, and the output speed, the computer can calculate how efficiently the transmission is working. If the speed is off, it knows that 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.
The P0716 code means that the computer has detected a value for the input sensor that’s either out of range (way too high or too low), or there’s a circuit issue (bad wiring, etc)
