It's quite well documented that the air temp sensor was incorporated into the MAP sensor and the wiring diagrams reflect this. If it has four wires, it's a dual sensor.
FWIW, the code I have in my book for the air temp sensor is 111, not 26. There is no code 26 for the Impreza since the codes begin at 31... Maybe your tech has read the code wrong and you're barking up the wrong tree?
