P0715 — Input/Turbine Speed Sensor Circuit Malfunction

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0715

P0715 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0715 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0715 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0715 fault code is set when the Transmission Control Module (TCM) detects a malfunction within the circuit of the input/turbine speed sensor. This sensor is responsible for monitoring the speed of the transmission's input shaft or turbine. It plays a critical role in helping the TCM determine shift timing and transmission control. The malfunction indicated by this code can be due to a variety of reasons, such as an outright failure of the sensor, wiring issues, or problems with the connections. A malfunction in this circuit can lead to improper transmission shifting patterns and reduced v...
