Common rail fuel pressure

[craka]

I have looked up my W/S manual (Russian CD) and it is complicated.


With engine CW temp @85 to 95 Deg C, transmission in neutral and all lights off, the common rail target pressure is 20 - 35 MPa at idle speed. Press the accelerator slightly and the pressure should increase (the amount would vary according to how hard you press).


The rail pressure sensor will bring up code PO191, 192 or 193 if the rail pressure varies by more than +/- 10 MPa.


4000 psi equals 27.56 MPa and 4500 psi equals 31MPa

Thanks Erad, I couldn't seem to find it in the manual.

Well all seems to be normal than as I'm between those two ranges at idle, and fuel pressure increase as the accelerator is pressed.

My NS idles at ~4500psi.
