Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature Sensor - Description
DESCRIPTION
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the air inlet tube with the sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as inlet air temperatures increase, resistance (voltage) in the sensor
decreases. As temperature decreases, resistance (voltage) in the sensor increases.
