P1DD1 Dodge Code - Input-Turbine Speed Sensor 1 Gradient Fault
Quick Answer
The Transmission Control Module (TCM) can detect rationality failures of the input (turbine) speed sensor and output speed sensor signals as well as the wheel speed and engine speed signals received through the Controller Area Network (CAN). Common causes include Faulty Transmission Control Module (TCM), Transmission Control Module (TCM) harness is open or shorted, Transmission Control Module (TCM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
