Sensor Help!

Recommended Posts

Was wondering if someone could help identify this sensor(with a name and part #) on my 2005 Legacy 2.5i (non-turbo) It appears to be broken. Also what affects could this sensor have on the car if not tended to promptly.


*Also a P0420 code popped up on my way home (which is when I noticed this sensor) Would this sensor have anything to do with it?
