Item to the left of the coloured wire is the MAP sensor (manifold absolute pressure) it senses the pressure in the manifold and tells the ecu to apply the right amount of fuel and timing ignition.

As far as i know they can't be repaired (i wait to be corrected) and you can get one from anyone who deals with subaru parts.

You could always reset the ecu to see if the code is wiped before spending money.

Tried re setting the ecu but came back with same codes 45 and 21 which was water temp

21 is located in the block by cylinder no.3 (orangey/brown sensor) if you didn't know
