RE: CM870 Turbocharger Speed Sensor
I'm not very familiar with the CM870 but have a good read of the fault code information. On the CM570, 595 is 'turbo speed data above normal' but generally means the boost is higher than the limits set for that eng speed and fuelling.

It could be actuator related, barometric pressure related, leaking actuator signal hose, etc. Not saying it won't be the speed sensor, but do some digging before you load up the parts cannon.
