Here is what I am recommending;

Sorry it took me a bit to get back to you...
Which O2 sensor was said to be bad?, because there is a front and a rear heated O2 sensor. Did the mechanic give the codes that he pulled from the ECM.
The intake air temp sensor doesn't have any effect on the running of the vehicle. It is located next to the battery in the intake stream. The harness should be checked so that is plugged in correctly and the power is being applied to the sensor. The harness will have a 5v source on the pin 2 (with lock up pin 2 is on the right) and the ground on pin 1 should be check with an ohmmeter. I would say have the codes pulled for free at Auto Zone or places like that the get the actual codes if he didn't clear them.
You can replace those parts but we need to make sure of what is bad first.
