P1747 Code - Electronic Pressure Control Solenoid 'A' Short Circuit
Quick Answer
The Diagnostic Trouble Code (DTC) will set if with the engine running in gear at cruise speed, the Powertrain Control Module (PCM) detects that the Torque Converter Clutch (TCC) circuit was shorted to power. Common causes include Faulty Line Pressure Solenoid, Line Pressure Solenoid harness is open or shorted, Line Pressure Solenoid 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.
