Hi welcome to just answers my name is ricardo. are there any codes stored on memory , do you have spark and injection signal?
Good morning sorry for the delay will you like to continue ?
Check scan tool Parameter Identification the pressure sensor located on rail. At first start the rail pressure should be about 5 Mpa at a cold idle. If the pressure reading is high (eg. 25 Mpa) and does not change when the engine speed is changed then measure voltages at the pressure sensor. Supply voltages at the pressure sensor unplugged: pin 3+ (Blue) to pin 2- (White) = 5 volts. Pin 3+ to ground = 5 volts. Pin 1+ (Yellow) to pin 2- (White) = 5 volts. Signal voltages at the sensor plugged in: Pin 1+ (Blue) to ground Key On Engine Off (KOEO) = 0.4-0.8 volts, engine idling = 1.5-2.0 volts. Signal voltage increases with engine RPM. If the voltage values are off, replace the high pressure fuel rail. Note that if fuel injectors are dislodged, the seals and mounting hardware must be replaced or cylinder head damage will occur. Reset Motronic Control Unit adaptations with the scan tool and then clear the faults before starting the engine.
P0193 Fault text Rail-pressure sensor, electrical: Short circuit to positive Fault description The diagnosis function monitors the upper voltage limit of the rail-pressure sensor. Test condition: The fault is recognized when the voltage of the rail-pressure sensor exceeds 4.5 V.
