Intake Air Temperature Sensor
WARNING: This page is about a different car, the 2016 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
The intake air temperature sensor is built-into mass air flow sensor. The sensor detects intake air temperature and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise.

| Intake air temperature [°C (°F)] |
Voltage* (V) | Resistance (kΩ) |
|---|---|---|
| 25 (77) | 3.3 | 1.800 - 2.200 |
| 80 (176) | 1.2 | 0.283 - 0.359 |
* : These data are reference values and are measured between ECM terminals.
