    Air Cleaner Temperature Sensor

    Air Cleaner Temperature Sensor Operation:

    Measures air and fuel mixture in the intake manifold. The engine control computer receives the signal from the sensor and adjusts the injector pulse width and fuel mixture. It senses the temperature of incoming fresh air and decreases the vacuum when the air is warm. When the air is cold, the sensor directs more vacuum to the air cleaner vacuum motor.
