Technical [20v-turbo] Ecu error code 89 (pressure sensor)?

[elberto]

Hi guys,
my Bosch ECU says:

89 - Pressure sensor

No help available
The reason for this fault is Short circuit at ground

What could it be?
Maybe APS sensor?
Or is there other pressure sensors somewhere?
Thanks.

I found this pressure sensor is APS pressure sensor for limiting turbine pressure.
