Help Boost pressure sensor failure jtd

Hi,
I have a problem with my 1.9 jtd 16v.When I accelerate to 2800 rpm the car goes in "safety modus" and "Engine failure"light fires. I hooked up the car to Alfadiag and the the fault code I found was "Boost pressure sensor failure". Does anyone have any tips about what that might be the problem?

This is the code:


Failed Component Code: Boost pressure sensor
Fault Symptom: Signal Not Plausible
Warning Lamp Status: Warning Lamp Illuminated
Fault Code Storage State: Error Not Present at time of request
Event Count: 40 count
Environmental Condition One: Engine Speed: 2564,77 rpm
Environmental Condition Two: Fuel Quantity: 58,35 mm3/str
Environmental Condition Three: Accelerator Pedal: 60,39 %
Environmental Condition Four: Rail Pressure: 1301,94 Bar
Environmental Condition Five: Turbo Pressure: 2729,48 mBar
Environmental Condition Six: Engine Temperature: 87,05 C

Re: Boost pressure sensor failure jtd

the overboost module/vnt controller is located on the front slam panel, you will see a vacuum pipe run to it, and one run from it to the turbo.
