Intake Air Temperature Sensor: Description and Operation
Fig. 21 Intake Air Temperature (TA) Sensor And Specification Chart
The Intake Air Temperature (TA) Sensor is a temperature sensitive resistor (thermistor). The resistance of the thermistor decreases as the air
intake temperature increases. This signal is used by the ECU to determine intake air density (oxygen content) for mixture control.
