I have p1470 (charge pressure negative control charge pressure high) Fault ,STAR Diag
Pressure too high, it seems there is turbo overboosting (i already fixed a turbo pipe leak and the fault changed from pressure low to high)
I found EGR transducer and turbo transducer pipes are disconnected
So I installed disabling EGR mod (more performance , no fault)
and I installed a pipe directly from the intake manifold to turbo transducer then to turbo actuator
the fault p1470 still appears , and the actuator doesn't seem to move
i tested the actuator and its working
Is it a bad transducer or wrong pipes connections ?
