DTC P0192: Fuel Rail Pressure Sensor Circuit Low Input; DTC P0193: Fuel Rail Pressure Sensor Circuit High Input [09/2014 - ]: Description
The fuel pressure sensor is installed on the delivery pipe. The sensor changes fuel pressure to an electrical signal and sends the signal to the ECM. Then the ECM controls the pump discharge using this feedback to maintain the fuel's target pressure between 2 and 18 MPa (20.4 and 183.5 kgf/cm2 , 290 and 2609 psi). If the sensor output stops, the ECM will stop the high pressure side fuel pump and supply fuel using the low pressure side fuel pump.
