CEL: Air Intake Temp Sensor...how accurate is that?

Hey guys,
I have a CEL. The codes are for: Air Intake Temp Sensor, O2 Sensor 1, and O2 Sensor 2.
The "O2 Sensor 1" doesn't concern me, I've had that code intermittently for 6 years and I have a new sensor and my SAAB indy mechanic scanned it multiple times while driving and everything is functioning OK.
So, really I have 2 questions as follows:
Regarding the Air Intake Temp Sensor code, does that pretty much always mean the Air Intake Temp Sensor is bad? Or, do these codes sometimes really signify other problems that may be masked by other problems, etc etc... If it's pretty much always the sensor, then I can simply order one and pop it in...I just want to make sure it's it before I go ahead and do so.
Lastly, regarding the second O2 sensor code (the rear sensor), what are the negative effects of this condition other than not being able to pass inspection? Would it hurt performance, mpg, etc? Just trying to see if I can wait on it. I assume the Air Intake Temp Sensor is what is muting my boost and lowering my MPG at the moment.
Thanks Guys!!!!
Alex
