Intake Air Temperature Sensor: Description and Operation
PURPOSE
The intake air temperature sensor (THA) is mounted in the airflow meter. It measures the temperature of incoming intake (ambient) air, so the
ECU can adjust injection duration. This aids with improvement in fuel atomization and decreases carbonizing within the engine.
OPERATION
The THA inputs the ECU through terminal THA.
