P1216 not currently present. My Maxysis won't give a code description for some reason.
Do you not have an information database ?
Am I right in saying the rail pressure control valve is working overtime too? From what I understand it should be at about 18% and any higher would indicate a leak? But with the rail pressure showing higher than desired I wouldn't expect there too be a leak. Correct me If I'm wrong, I still have a lot to learn in diagnostics.
Again an information database would tell you this, AD, Global ........
It's no good testing in dribs & drabs, get the vehicle & go through it methodically from a road test with the scan tool graphing data to the scope attached to see in real time with a quicker refresh rate than the scan tool & in the workshop environment making the car think it's on the road & thinking it does have a leak & watching the ECU's reaction !
Get yourself an info database it's no good without.From my information database...........
P1190 Rail Pressure Control Valve Stuck
.Sensor signal out of range
P1216 Rail Leak Detected
.Common Rail Pressure Too Low
Rail Pressure Control Valve Pulse Ratio <50% @ Idle
.APP not actuated
As I said get an information database as without you're in the dark & can't just rely on being spoon fed in hope for silver bullets !
