P1DD1 Chrysler 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.

Code P1DD1 Chrysler Description
The TCM performs three diagnostic checks that include:
- Multi sensor comparisons of up to three speed signals (input, output and wheel speed).
- Monitoring of the gradient of the input speed signal.
- Double failure monitoring to determine unique failure situations which could require unique limp-in functionality.
