P0192 RAM Code - Fuel Pressure Sensor Voltage Too Low

Quick Answer

The Engine Control Module (ECM) monitors the Fuel Pressure Sensor with the ignition ON and the battery voltage greater than 10.4. Common causes include Faulty Fuel Pressure Sensor, Fuel Pressure Sensor harness is open or shorted, Fuel Pressure Sensor 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.
