Default '04 RS Intake Sensor (Please help identify)

Hello,

I have an '04 RS which has had the engine light on for quite a while. A friend of mine and fellow impreza owner came over with his code reader and identified that my car had two codes showing.

The first code was for a fuel tank filler cap leak which is an easy enough fix (I will probably source from the dealer, but if anyone has had luck in the aftermarket world, let me know)

The second code was for something along the lines of an intake temperature sensor (Forgive me, it was a while ago that he read the code to me, and I forget the code itself and description) I believe this is the sensor which is located in the plastic air filter box above the throttle body on the left (passenger) side. Can be seen in attached image of a legacy engine.



Can anybody confirm this? To me it would make sense as I have been experiencing VERY poor fuel economy (blown sensor possibly reading too cold of a temp and adding more fuel to compensate)

Any help would be great - I kind of want to know what it is i am talking about before I phone the dealer to order the new part, or accidentally order an incorrect part.

Right the readings will be too far off from the coolant temp sensor and will probably mess with your closed loop open loop operation/ Leaning and enriching the fuel air content.

It should be cheap and readily available from any parts store
