Intake Air Temperature Sensor

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2000 Nissan Xterra, 2000 Nissan Sentra, 2000 Nissan Quest, 2000 Nissan Pathfinder, and 2000 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Intake air temperature sensor is mounted on air duct housing. Sensor monitors temperature of incoming air. Sensor is a thermistor and increases (cold) or decreases (hot) its resistance in response to temperature changes. This input is only used for on-board diagnosis and is not used to control engine operation.
