Inlet Air Temperature Sensor

The Negative Temperature Coefficient (NTC) resister located within the intake air temperature sensor alters it's resistance in line with the charge air temperature. If the engine is cold, the value equals ambient temperature. For a temperature of 68°F (20°C) the resistance is approximately 6000 ohms. For a temperature of 104°F (40°C) the resistance is approximately 3300 ohms.
