Intake Air Temperature Sensor: Description and Operation

Intake Air Temperature Sensor (THA)

    The Intake Air Temperature Sensor is mounted in the air cleaner housing.  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.  The THA inputs the ECU
through terminal THA.
