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.
