Hi guys I have a problem on a polo 1.2 tdi cod engine CFW me in the diagnosis p0088 fuel pressure too high, in fact when I go to read the fuel pressure me, I find it to 600 bar to a minimum, to someone ? ever had a situation like that?
The car on the way to pi? 3000 rpm should not be

The machine definitely ? in recovery... You have problems with the pressure sensor in place on the pump hp

but ? the original or mapped?
With 600 bar in those rounds ? normal recovery , also dare not imagine how I'm lia motor

Not ? mapped, with the measures which I have made known to the regulator fuel has a resistance of 4 ohms, while I say engineers who have worked on these engines that the resistance should be 18 ohms. Second you can? being that I have problems with the fuel regulator?

Pi? you've written to check the pressure sensor.......

[danny677]

The pressure sensor ? the first defendant however on the power wiring of the sensor make sure that it is powered at 5v accurate and that the mass is affixed otherwise, even if we replace the problem you have.

5v power supply ? this, mass

Then the wiring ? ok....
