engine codes,help!!!!

hi,ive these following codes - code 22 knock sensor, code 32 oxygen sensor and code 45 presure sensor. can anyone tell me were these are located or even better any pics? will all these need doing or will one of them throw the rest out? the car is only boosting up to 0.5 bar but sometimes while driving boost to around 1.0 bar but doesnt stay like that for long. any help will be great as im a newbie to subarus.

The knock sensors under the intercooler at the back of the engine. Im having problems with half boost in 2nd gear and im getting the 22 fault code. Im thinking about changing it.

The oxygen sensor is on the exhaust you have one down from the turbo near the 1st catlyic converter and the 2nd oxygen sensor is near the 2nd catlylic converter but think the code 37 shows up a fault with the 2nd oxygen sensor and that pressure sensor located top of trottle body..............

had a good look around the engine today and found out the pipe work on the solenoid was on the wrong way around,ive got the 3 port solenoid and my top port was connected to the nipple on the turbo not the actuator and middle to the actuator not turbo, so hopefully now fault code 45 wont show up and the car will boost better.ill let you all know once ive swapped them all around
