Hi RPMex,Certainly no rush I appreciate your time more than I can say!
...
When the new angle sensor is in and set to 4.4V I turn the engine on and the first thing i notice is the engine seems to be under a little load also hydraulics are so fast they stall out the engine, or if I close the bucket and hold it the engine immediately stalls. After a few of these movements the angle sensor kicks down to around 1V and now the hydraulics become very slow. However if I multifunction the speed seems to come back towards normal. I can still idle up fine and there does not appear to be any load on the engine now. Could it be that the new angle sensor is faulty or what would cause it to lose voltage like this? I can unplug the 2 solenoids and the angle sensor goes back to 4.4V with no adjustment needed. I'm still manually getting code 22.

I have checked the harness from the solenoids to the PVC and PVC to ground and they have continuity.
I replaced the angle sensor and it is currently set to 4.4V. I notice that if I move the hydraulics and multifunction for a bit the voltage on the angle sensor kicks down to 1.1V and the machine becomes very slow. If I preform the angle sensor adjustment it automatically goes back to 4.4V without needing to be adjusted and the machine goes back to stalling.
It means the "Pump control system" is currently faulty.I will check these and get back to you shortly. See below the diagnostic results show PVC does just mean that’s what the MPDr is looking at or is that what’s at fault?View attachment 234205 View attachment 234206
Check the No. 1 PUMP displacement solenoid valve.
It's sure.From your pictures Solenoid 1 is closest to the entry door and solenoid 2 is closest to the engine. Can you confirm as my manual shows the opposite and the wiring diagram seems too as well.
It’s an EX 100-2 s/n 12L-30145
I suggest you look at Angle sensor bolt. It has a Elliptical hole allows you to adjust the position of the sensor, then try to adjust it......
However I do have slow hydraulics especially with the boom up function and walking the machine
Lachau would you mind looking at these numbers again now that I have cleared up the codes. Could it be something in the actual hydraulic system itself? The pump delivery pressure and flow rates seem low.
