Default Error Code P0558

Hi Guys

After some help with the following error I've got on my 04 WRX - P0558 Brake Booster Pressure Sensor Circuit High

Has anybody got a direct fix for this such as replacing a sensor?

Also where about is the sensor and piping for his located in case it is just a case of clean up a sensor, checking cabling etc

Thanks
Luke
