Circuit Diagram
Description Intake Air Temperature Sensor (IATS) is included inside Barometric Pressure Sensor (BPS) and detects the intake air temperature. To calculate precise air quantity, correction of the air temperature is needed because air density varies according to the temperature.
Inspection 1. Ignition "OFF" 2. Disconnect ambient temperature sensor. 3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature. 1. Sensor Ground2.
Inspection 1. Ignition "OFF" 2. Disconnect the connector of temperature control actuator. 3. Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 3 and grounding terminal 7. Verify that the temperature control actuator operates to the cool position when connecting in the rev
