In this video I show you how I test the fuel rail pressure sensor when there is P0191 Fuel Rail Pressure Sensor Circuit Range/Performance fault code. I perform the test on a KIA Rio 2012 with GDi fuel system. During diagnostic, I explain the wiring diagram for sensor, I explain the step by step diagnosis on the wiring and at the same time I show you how o find the wires and pins on sensor connector and PCM connector. I also explain how to test the sensor operation by monitoring the live data on scan tool.
