Help Identifying Sensor Plz 2010

[floridaimpreza]

Hello forum,
I'm hoping someone will help me id one of the sensors in my 2010 non turbo engine. On the drivers side of the engine is the camshaft position sensor, then to the left is the variable valve timing solenoid, then to the left of that is a third sensor that I have not be able to id. In my case the third sensor has a round white housing. There was a small fire on top of the engine at that spot so I have to replace those 3 sensors and the wiring and housing. I haven't been able to find the wiring or housing parts yet either.
Thanks for your help!

You are mistaken. That solenoid on an N/A engine is the Variable Valve Lift solenoid and that switch is the the VVL oil pressure switch - sometimes called the VVL diagnostic switch.
Go to https://parts.subaru.com/ enter your year/model/engine/body or your serial number then look under Engine and Cooling - Cylinder Head System. in the image below it is item 25240

As far as wiring - best bet is a junk yard or buy a complete engine harness...
