Order of inspection
P0193 Fuel Rail Pressure Sensor Circuit High Input High
The P0193 code means the voltage from the fuel rail pressure sensor went above the maximum possible value. It points to an electrical fault, not to a pressure that is really too high: a short to a voltage line, an open ground or a sensor broken inside. The engine goes into limp mode as a safety measure.
