Specifications of the intake air temperature sensor

1. The IAT sensor is classified as a two-wire thermistor.
2. The typical temperature measurement accuracy is within  ±2°C to ±5°C.
3. This sensor has a very short response time.
4. As the temperature increases, the resistance of the sensor decreases. 
5. The resistance of the termistor at 25°C can be in the range of 2.0 kΩ to 5.0 kΩ.
6. The IAT thermistor is generally positioned in the air filter box or the intake manifold.
7. This sensor uses the standard connector type of the Bosch EV1 connector. 
8. The connector type is an AMP SCS.
9. The specified operating temperature of the sensor is between -40°C and 125°C.
10. The specified storage temperature is between -40°C  to 130 °C or higher.

Application of intake air temperature sensor

1. The IAT sensor gauges the temperature of the incoming air to an engine. This information is sent to the ECU to improve engine function and fuel efficiency.
2. The IAT sensor, when used in conjunction with other sensors, can assist the ECU in calculating the engine's air mass. 
3. Using the IAT sensor, the ECU will optimize the air-to-fuel ratio for effective combustion and engine efficiency. 
4. Modern EFI systems utilise these sensors to assist engine control.
5. Using IAT data, the ECU can optimise ignition timing in order to enhance overall engine performance. 
6. In-home or industrial applications, these serve to measure and monitor air intake temperature.
7. Both diesel and petrol engines utilise these in order to improve fuel and performance efficiency. 
8. In motorsport, these sensors improve engine function and assist with the consistent delivery of fuel in eve-changingg environments. 
9. Within non-condensing HVAC-based applications, some sensors can be used to measure air duct temperature.
