Causes and Fixes P0715 Code: Input/Turbine Speed Sensor “A” Circuit

How to fix P0715 Code: Input/Turbine Speed Sensor “A” Circuit A P0715 code is set when the computer (TCM/PCM) detects irregular signals sent by the transmission input speed sensor. The sensor is often located outside the transmission but can also be located inside. There can be multiple speed sensors on a transmission, so be sure to get a diagram of all the sensor's locations. Possible Causes of a P0715 Code: Bad Input/Turbine Speed Sensor Low Transmission Fluid Wiring (Open/Short) Transmission Issues Bad Computer (TCM/PCM) By using this information user assumes all risk of use.
