Fiat Punto Evo, 1.4 8V, 2010. - ODB code P0555 - kingfox10

I am getting on a regular basis P0555 Brake Booster Pressure Sensor. This code can be cleared for a while. Checking around the brake master cylinder there is no evidence of a sensor. The servo is mounted inside the car behind the dash. No easy access. The brake 'feel' is very good. Is this a generic code for something else I wonder? Or could this be an ABS pump issue? Thanks for your help in advance.

The pressure sensor is engine bay side , up near the bulkhead. Very difficult access. It’s in the vacuum boost circuit.

Thanks for the information. The ODB message is misleading. It should read vacuum sensor. I will have a further look around the back of the bulkhead.
