P1D70 Code - Traction Motor Phase Current Sensors Multiple Failure
Quick Answer
The motor control module (traction) uses two small control deviation values of a specified values of a motor phase current sensors three phase signals to controls the traction motor output. Common causes include Faulty Traction Motor Phase Current Sensors, Traction Motor Phase Current Sensors harness is open or shorted, Traction Motor Phase Current Sensors 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.
