I would begin by having the vehicle scanned for Diagnostic Trouble Codes (DTCs). The code (or codes) will provide a good starting point for the fault diagnosis.

The intake air temperature sensor is basically a thermistor. It changes resistance (in ohms) with air temperature. Have you had the code cleared since the sensor was plugged back in?
